Description MV-C


3. Description MV-C

The MV-C series is a series of air-insulated control panels for the op-

eration of medium voltage motors (for conveyor belts, pumps, shred-

ders, etc.) with a rated voltage from 2.3 to 15 kV.

MV-C panels are available in several basic configurations; these are

basically governed by the built-in relay:

ISA-HD MV soft starter

IAT-HD MV autotransformer

DOL-HD MV direct online starter

A wide range of options and configurations allows customisation as

specified by clients. The basic layout of the panels is always the

same, and some operating controls are always executed the same.

The MV-C control panels can be designed as single units or as sev-

eral units connected to a switchgear unit in a line-up.

In addition to MV-C motor start panels (soft starter, autotransformer

or direct online starter), there are also other configurations – as addi-

tional panels to these and generally intended for use in line-ups:

Input panel

Output panel

Coupling panel

Bus riser panel

Metering panel

Capacitor array

3.1 Housing properties

3.1.1 General

The frame, the outer housing and the inner walls of the MV-C control

panels are made of galvanised and partially painted steel plate. Walls

and doors or service doors are designed to be pressure resistant.

The frame elements are welded or bolted, the walls and doors bolted

or fitted with locks.

Description MV-C


Depending on the version, internal partitions and seals according to

partition classes LSC1, LSC2A and LSC2B (refer to Fehler! Ver-

weisquelle konnte nicht gefunden werden. on page Fehler!

Textmarke nicht definiert.) ensure safe access to the built-in

switchgear in the switchgear compartment or to the fuses, even when

power is flowing through the busbar.

The low-voltage compartment is completely sealed off by a sheet

steel housing from the medium-voltage area.

Doors and exterior walls are painted in standard colour RAL 7035

(other colours on request).

The doors of the medium-voltage areas are pressure resistant and

equipped with composite locking systems in different executions (op-

erated by a central lever handle).

Partitioning

The medium-voltage areas in the MV-C panel are mechanically com-

pletely sealed off to the outside, to each other and to the low-voltage

compartment (subdivided in individual compartments and LSC clas-

ses depending on the version).

An optional power supply transformer for control voltage is installed

in the medium-voltage area, the outgoing low-voltage supply cable is

routed through the partition. Here the essential galvanic isolation in

the transformer ensures that there can be no medium voltage in the

low-voltage area.

The control units for the ISA-HD soft starter are connected via fibre

optic cables to the medium-voltage section, this also provides gal-

vanic isolation.

Description MV-C


Housing walls

The walls of the control panel, as far as they do form opening doors

or panels, are also screwed to the frame in the same way as the bot-

tom and the cover.

Side walls are only installed if they are exterior walls of a single con-

trol panel or if the panel is at the beginning or end of a line-up. A gal-

vanised partition is installed between two adjacent panels of a line-up

instead of the two facing side walls. These partitions are provided

with feedthroughs for medium-voltage busbars as well as openings

for continuous control lines and earthing bars.

Figure 2 Links: Partition, pre-assembled. On the right: Dia-

gram of the connecting elements between panels.

Pressure-relief dampers

The medium-voltage areas (busbar compartment, terminal compart-

ment and switchgear compartment) have pressure-relief dampers fit-

ted and secured at the top. These open upwards when excess pres-

sure is caused by an internal arc.

The pressure-relief dampers are fastened with steel screws on one

long side and with plastic rivets on the other. The plastic rivets form

the predetermined breaking point in case of internal excess pressure.

Description MV-C


Figure 3 Top of a MV-C panel with pressure-relief dampers

Attention

To ensure that the pressure-relief dampers function correctly, nothing

may be placed or stored on top of the housing.

In addition, sufficient distance from the ceiling must be provided for

so that the dampers can open freely.

Description MV-C


Cable glands

Depending on the selected version of the MV-C panel, there are sev-

eral versions of entries and exits for medium-voltage cables and con-

trol cables.

For the routing of cables from top to bottom or vice versa cable

shafts from sheet metal are built in, separated for low (1) and me-

dium voltage (2).

Using these, the cables can also be laid in the housing when the side

wall is closed.

Specially prepared aluminium plates (3) fastened with screws to the

bottom or the cover can be removed, equipped with the necessary

bushings for medium voltage cables and then reinstalled.

Figure 4 Cable glands and feedthroughs for low and medium

voltage (as per the example of the ME version)

Alternatively, a sliding flange with a foam rubber strip is installed in

the base plate in the basic version of the MV-C control panel, through

which the customer can insert his medium-voltage cable in the hous-

ing.

Description MV-C


Figure 5 Sliding flange

The red pin indicates the area where the cable is inserted into the

housing between the two strips of foam rubber. The earthing bar can

be seen in the foreground.

Identification Plate

The aluminium type plate is always fixed to the front of the MV-C

panel. A white plastic label contains all the project-specific perfor-

mance data.

Description MV-C


3.1.2 Locks

Low-voltage compartment

The low-voltage compartment is secured with double-bit locks to pre-

vent unauthorised opening.

Attention

The double-bit key must be kept where it cannot be accessed by un-

authorised users. It is possible to open the door to the low-voltage

compartment during operation.

Figure 7 Double-bit lock and latch

Medium-voltage compartments

Depending on the cabinet design and electrical short-circuit capacity

of the installed components, the doors of the medium-voltage com-

partments must be secured mechanically and electronically in a dif-

ferent way.

Type of closing operation

The medium-voltage doors in all systems have coupled closing

mechanisms with central pivot lever actuation. There are differences

in the number of tumblers and in how they arranged along the door

edges. For types with lower internal arc protection, tumblers are in-

stalled only along the front edge of the door, how many depends on

the height of the door.

Description MV-C


Three-sided locking is available from internal arc protection of 31.5

kA. These doors are thus kept in place on all sides by latches or

hinges.

All locks are actuated by pivot lever. These are always at least me-

chanically secured against inadvertent actuation, e.g. by first having

to be flipped open to be actuated. In addition, they can also be fitted

with cylinder and/or electronic locks.

Please refer to your project documents for information on the exact

type.

Figure 8 Pivot lever for three-sided locking

Caution

The keys must be kept in a safe place to prevent unauthorised use.

Electrical safety precautions

It is not possible to open the medium-voltage doors during operation.

This requires first of all – if available in each case – the disconnector

to be opened and the earthing electrode to be closed. Only then is it

allowed to open the door. In some versions, this is ensured by a lock-

ing mechanism.

If neither a disconnector nor an earthing electrode is installed in the

cabinet because an external power supply with the corresponding

components is connected upstream, these must be unlocked first.

Then, the enable signal is supplied from there to the door lock, if

Description MV-C


such is present. This way too, it is ensured that the section of the me-

dium-voltage area, which is accessible after the door is opened, is

not under voltage.

When the medium-voltage doors are being opened, door contacts

deliver a message ‘door open’ to the external controller. This way it

can be ensured by means of a status signal that the power to the

plant is not reconnected when the door of a medium-voltage area is

open.

3.1.3 Earthing electrode / disconnector

The actuating mechanism for the earthing switch, if applicable, cou-

pled with the actuation of the circuit breaker is equipped with a cou-

pling for a removable actuating lever, which can be operated through

a slot in the housing front.

Figure 9 Actuation of the disconnector / earthing electrode

The actuating coupler in the housing front is blocked by a slide (1),

which can be secured with a padlock. The switch positions are visu-

ally identified:

Cross fade visible (1) Actuating coupler blocked. Lockable in this

position.

Marker is horizontal (2) Switch position disconnected, earthed = safe.

Marker is perpendicular (3) Switch position not disconnected, not earthed

= in operation.

Deviating from this or in addition to this, another electromechanical

locking mechanism for an earthing electrode can be installed. This

ensures that the earthing electrode can only be operated when the

plant is turned off.

Description MV-C


In such a case, a lock switch (left) must be activated to release the

coupler to start the actuating lever (right).

Figure 10 Earthing electrode secured electromechanically

The actuating lever for the disconnector / earthing electrode is usu-

ally kept in a holder in the low-voltage compartment.

Figure 11 Storing the lever

Colour and shape coding

For distinction purposes, the couplers for the actuating levers are

shaped differently, depending on whether it is a pure earthing elec-

trode or a disconnector or a combined earthing electrode / discon-

nector.

Earthing electrode: the signal stripe on the coupler head is red,

as is the ball on the end of the lever

Disconnector, disconnector/earthing electrode: Signal stripe and

ball are black.

Delivery, transport and assembly


4. Delivery, transport and assembly

4.1 Scope of delivery

In addition to the panel itself: Fastening material for busbars and

other terminals is packaged either separately and included with the

delivery, or it is pre-assembled in the appropriate position.

All other auxiliary equipment necessary for operation are included.

This includes for example the ISA-HD soft starter, a test cable set for

the function test with 400 V.

Figure 21 test cable set in packaging

4.2 Condition on delivery

The MV-C panels are delivered factory-assembled and tested to

function correctly, all doors and dampers are closed. All panels are

factory-checked that they correspond with the order and comply with

all the relevant regulations.



The double-bit key for the low-voltage compartment door is tied to

one of the lifting eyes with a cable tie during delivery.

Figure 22 Double-bit key on delivery

4.3 Packaging

The control panels are individually packaged in an upright position for

transport by truck on pallets. Several layers of PE-LD film are

wrapped correctly around all sides (according to TL 8135-0019 and

DIN 55530).

Bags with desiccant (certified according to DIN 55473) are hung in or

on the panels at suitable positions inside the film packaging.

Figure 23 Desiccant for transport



Figure 24 MV-C control panel wrapped in film.

For transport by sea in standard containers, the control panels are

delivered by lorry to the packager where they are packed in crates

made from wood and wood materials. The regulations of the con-

tainer manual apply.

Figure 25 Wooden crate for loading in sea containers.

These crates are then stowed in containers for sea transport



4.4 Transportation

Position during transport

MV-C control panels may only be transported upright. If local condi-

tions require transportation in a different position, it must be coordi-

nated with the manufacturer in advance.

Protection against vibrations and shocks

Protect the MV-C units during transport to prevent excessive impact

and vibration.

Load securing

Observe the general rules and regulations for securing cargo for

transport by road, rail or sea.

Suitability for crane use

MV-C control panels are fitted with lifting eyes at the top. Suitable lift-

ing equipment for loading and unloading and suspended transport,

for example in halls equipped with gantry cranes, can be hooked

onto these.

Caution

The lifting eyes are designed for a single load of no more than 700kg.

Thus, taking a margin of safety into account, panels or transport units

up to a maximum total mass of 2,500 kg can be lifted by the lifting

eyes. The lifting eyes are not removed from the panels also after as-

sembly at the installation site.



Figure 26 Lifting eye

Alternatively, angle irons can be bolted along the top edges of very

large and heavy panels to spread the tensile force to more points on

the housing to handle heavier loads than which the lifting eyes can

do only on the corners.

These so-called crane brackets have to be removed after the panel

has been transported, for one thing because they could obstruct the

functioning of the pressure-relief dampers.

Caution

The length of the chains/belts must be such that an angle of 30 ° ver-

tical or 60 ° horizontal is not exceeded.

Figure 27 Maximum angle of the load slings

MV-C panels are factory-fitted with transport timber bolted to the bot-

tom. These allow the lifting and transport by lift truck, forklift or crane

fork.

They are bolted through the holes for floor installation and have to be

removed during installation.

When transporting by forklift, lift truck or crane fork, the forks must go

in all the way under the control panel. If the forks stop under the base

plate, the latter can be damaged when being lifted. In the worst case,

the control panel can tilt and fall from the forklift, causing serious

damage.

Figure 29 Proper forklift transportation

4.5 Delivery

When the switchgear is delivered, your responsibilities as customer

include the following:

Checking the delivery for completeness and integrity (e.g. also

for moisture and its adverse effects). In case of doubt, the pack-

aging must be opened and then sealed again properly if stored

temporarily; new bags with desiccant must then be placed in the

packaging, if any were present.

Documentation and reporting of damage and defects. If any

parts are missing or defects or transport damage is found, you

have to do the following:

০ Note the relevant event or defect on the delivery note.

০ Notify the relevant carrier or forwarding agent immediately,

in accordance with the applicable liability provisions.



Always document damage by taking photographs of it.

4.6 Temporary storage

Should temporary storage be necessary, optimal storage without

negative effects depends on ensuring a number of minimum condi-

tions for the control panels and installation materials.

Panels with basic packaging or without packaging:

A dry, well-ventilated storage area whose ambient conditions

meet the requirements according to IEC 62271-1

The room temperature must not fall below -5 °C

There must be no other negative environmental influences

The control panels must be stored upright

The control panels may not be stacked

Control panels with basic packaging: open the packaging, at

least partially

Panels without packaging: cover the control panels loosely with

protective film

Ensure adequate air circulation

Check the control panels regularly for condensation until they

are installed.

Control panels with seaworthy or similar packaging with protec-

tive film:

Store the transport units:

০ protected from the weather

০ in a dry place

০ protected against damage

Check the packaging for damage.

Check the desiccant (see also section 4.2):

০ on delivery

০ periodically thereafter



After expiry of the maximum storage time from the date of pack-

aging:

০ The protective effect of the packaging can no longer be

guaranteed.

০ Take appropriate measures if the temporary storage

needs to be continued. Consult IGEL Electric GmbH if

necessary.

4.7 Assembly

4.7.1 General

Before starting the installation, the proposed switch room must be

fully completed, have lighting and power supply, be lockable, dry and

equipped with ventilation devices. All necessary preparations such as

wall openings, conduits, etc. for the routing of power and control ca-

bles to the switchgear must be completed.

The ground or the supporting structure (intermediate floor) must be

strong enough to support the weight of the switchgear.

Attention

When planning the room for the switchgear, sufficient distance to the

ceiling must be ensured, so that the pressure-relief dampers can be

opened unobstructed in an emergency. The ceiling height must con-

form to the IEC standard.

In some cases, additional measures to protect the operator at the

control panel may be required, e.g. deflector plates or discharge

channels.

Also take note of prescribed or technically required minimum clear-

ances to side and rear walls in accordance with the contract docu-

ments.

4.7.2 Remove packaging

Remove the packaging from the control panel with suitable tools

without damaging it. Remove all packaging and transport material

from the assembly area.

Clean the assembly area of all packaging waste and dirt.



Dispose of packaging according to local regulations.

4.7.3 Anchorage to the floor

IGEL Electric GmbH recommends the installation of a steel base

frame in the floor. Also possible is the retrofitting of flat iron bars on a

concrete base, to which the control panels are bolted. Alternatively,

the control panels can also be installed directly on precisely levelled

concrete floors or on raised floors.

Refer to the specific project documents for the relevant measure-

ments of the unit footprint. Please refer to the individual measure-

ments in the construction drawing for the bottom plate relating to the

order.

In an ideal situation, the base for the installation of the control panels

has been measured before installation. Before anchoring the control

panels to the base, the measurement log can be evaluated and, if

necessary, an absolutely horizontal surface can be created with

shims for the installation of the control panels.

When a line-up is installed, the entire surface under all control panels

/ transport units of the line-up must be uniformly level and horizontal.

This is primarily the current-free connection line-up elements to be

assembled side by side; uneven surfaces will also twist the frames

causing control panel doors to stick or not close tightly.

4.7.4 Assembly in the line-up

When assembling line-ups you should follow the following sequence:

1st After having placed the control panels in place by forklift or

crane, align the first panel of the line-up on the base frame ac-

cording to the drawing. The other control panels are placed at a

short distance parallel to the first control panel.

2nd Next, screw the panels together.

The partitions are pre-assembled to a respective panel. The ex-

isting lead screws are used to determine the positioning of adja-

cent panels to each other and stay in place.

The sealing material is already attached to the open side of the

adjacent panel, if the panels are intended for assembly soon.



Rear walls, roof panels or parts may have to be remove to gain

access to screw connections if access is not possible through

the doors.

When a longer storage period is envisaged, the sealing material is

not pre-assembled, but included in the delivery and must be applied

on the sealing surfaces before assembly.

3rd Now comes the connection of the busbars.

In switchboards with busbar partitions, the feedthroughs are pushed onto the busbars beforehand.

Grease the joints of busbars with suitable grease. If necessary, pull insulating covers over the busbars. Install and connect the busbars with the included or pre-assembled fasteners.

Figure 30 Connecting elements of the busbars

4th Then the panels are screwed onto the bottom. Rear walls or

parts may have to be remove to gain access to screw connec-

tions if access is not possible through the doors.



Attention

The rear walls of panels of higher internal arc classification are very

heavy due to the double plates. This needs to be taken into account

during handling.

If necessary, the individual control panels or transport units must be

realigned to each other to compensate for gaps that occur by having

been screwed to the bottom. Gaps up to 2.5 mm wide can be sealed

with sealant.

Figure 31 Drawing of the assembly of line-ups

5. Finally, reinstall rear walls or other housing covers necessary for

floor anchoring where applicable.

4.7.5 Connection

Earthing the switchgear

Connect the earthing bar according to the wiring diagram with the

connectors in each control panel.

Make sure that the wiring connection of the bottom frame or the

cavity floor is protected.

Connect the PE conductor to the main earthing terminal of the

switchgear.

Connecting the cable

Caution



Please refer to chapter Commissioning for the type and possibly the

time of connecting the plant to the medium voltage.

Medium-voltage cable

The cable terminations must be attached to the cable cores accord-

ing to manufacturer specifications. It is possible to use cable termina-

tions from different manufacturers, while maintaining the same length

of cable ends including the terminations, which is determined by the

distance of the cable terminal busbars from the control panel floor.

These bars come in different versions, which differ in the number of

parallel cables and the values of the rated and short-circuit currents.

Installation procedure for medium-voltage cables:

Insert, cut to size and strip medium-voltage cables.

Adjust reduction rings to the cable diameter and attach to the ca-

ble.

Prepare cable terminations and attach them to the cable cores

according to manufacturer specifications.

Connect cable lugs with strain relief to the prepared terminal

strips.

Connect the earthing of the cable.

Install the ground cover parts.

Push reduction rings down until the nuts in the rings sit in the

corresponding recesses in the floor coverings. This seals the ca-

ble glands.

Connect the cable with the prepared cable terminals (the maxi-

mum tightening torque for the terminal screws is 9 +2 Nm).

Low-voltage cables

The low-voltage cables are routed through the low-voltage cable

channel or the low-voltage cable entry gland in the roof panel in the

control panel.

Installation procedure

Run the cable through the cable channel or the feedthrough in

the roof panel.



Fasten the cable to a suitable location, remove the insulation and

run the control wires into the low-voltage compartment.

Connect the control cables to the terminal block according to the

wiring diagram.

Prepare the control line connections to adjacent control panels

using the feedthrough.

Special screw connections

Attention

Note that screw connections for electrical connections (e.g. the con-

tacts of capacitors) are designed for much different tightening tor-

ques or must be specially supported during the screwing action. You

will find information, where appropriate, on a label on the respective

equipment as well as in the technical documents on the equipment.

Figure 32 Special torque specifications for electrical connec-

tions

4.7.6 Final tasks

Check the painted areas of the control panel for damage and

touch up to keep protected against corrosion if necessary.

Check the screw connections and retighten if necessary, espe-

cially the connections that are made during the on-site installa-

tion of busbars and earthing system. Please pay attention to the

prescribed torque (see Fehler! Verweisquelle konnte nicht

efunden werden. on page Fehler! Textmarke nicht definiert.

in the Annex).

Clean the control panel thoroughly.



Make sure that no loose parts are left inside (tools, screws,

washers, nuts, etc.) after installing the plant.

Correctly replace all the covers that were removed for assembly

and connection tasks.

Close all remaining openings in the housing when they are no

longer needed.

Check that the break contacts and locking mechanisms operate

smoothly and lubricate if necessary (see chapter 8.2.2 from

page 67.

Carefully close all dampers and control panel doors.

Perform the High-Pot test as well as the Megger test when line-

ups or control panels were assembled from several transport

units.

Switchgear configuration


5. Switchgear configuration

5.1 Main components

5.1.1 ISA-HD soft starter

The ISA-HD is an advanced and reliable digital soft starter for use

with three-phase medium-voltage motors (synchronous or asynchro-

nous). It limits the current inrush and prevents torque surges at start-

up. This relieves the medium-voltage grid and reduces the mechani-

cal load on the equipment driven by the motor.

The ISA-HD continuously increases the terminal voltage of the motor

in the start-up phase and so provides a soft start and smooth accel-

eration at the lowest possible starting current. The microprocessor

control provides special properties such as pump control, compre-

hensive motor protection and optional analogue outputs.

The – optional – RS485 serial port for MODBUS, PROFIBUS and

other systems (on request) allows complete remote control and ob-

servation (start, stop, dual setting, etc.).



Figure 33 ISA-HD soft

starter

5.1.2 IAT-HD auto-transformer starter

The IAT-HD autotransformer starter reduces the motor voltage during

the start-up phase with the aid of a transformer and related contactor

control. This is done to increase the voltage in specified steps.

Figure 34 IAT-HD auto-transformer starter

5.1.3 DOL-HD direct starter

Except for measuring and control components and a circuit breaker,

no special start-up controller is installed in the direct starter panel.

The DOL starter switches the mains voltage directly through to the

connected motor.



5.2 Secondary components

5.2.1 Circuit breaker

Circuit breakers are usually installed in input panels or in DOL pan-

els. They can be permanently installed or as a pull-out circuit

breaker.

Figure 35 Permanently installed Siemens circuit breakers

A completely voltage-free condition can be produced when the pull-

out circuit breaker is pulled out from the contact, with the creation of

an air-insulating gap.

Figure 36 Pull-out circuit breaker.

1 Before installation in the control panel

2 Pulled out

3 Pushed in



5.2.2 Contactor

Contactors are used as line and bypass contactors.

Figure 37 Contactors (left 3.6 kV, right 7.2 kV)

5.2.3 Motor protection relay (optional)

The motor protection relay is an optional component. It protects the

motor against overload or failure of an outer conductor. Further tech-

nical specifications can be obtained from the manufacturer.

Figure 38 Motor protection relay in MV C-Basic with ISA-HD

(outside operator panel and cable connections at the

back)



5.2.4 Earthing electrode (optional)

The earthing electrode or earthing switch connects a control panel

with the

earth, so that induced voltage is conducted directly to the earth. To

prevent damage, the equipment must always first be discon-

nected/turned off.

Figure 39 Earthing electrode earthed in switch position.

5.2.5 Disconnector (optional)

A disconnector or circuit breaker disconnects the control panel from

the medium voltage.

Figure 40 Disconnector disconnected in switch position.



5.2.6 Control voltage transformer (optional)

Optionally, a control voltage transformer that is used to power the

controller, can be built into the MV-C panel. Alternatively, the control

voltage can be supplied from the outside.

Figure 41 Control voltage transformers.

5.2.7 Current transformer (optional)

Current transformers are measuring instruments for floating meas-

urement of large AC currents. They are used to monitor the amper-

age.

Figure 42 Current transformer



5.2.8 Voltage converter (optional)

Voltage transformers are instrument transformers for the floating

measurement of high AC voltage. They are used to monitor the me-

dium voltage.

Figure 43 Voltage converter

5.2.9 Multifunction display (option)

The multifunction display is used to display various system parame-

ters: Voltage, current, etc. separately for each phase of the medium

voltage.

Figure 44 Multifunction display



5.2.10 Anti-condensation heater

To prevent condensation from forming, a thermostatically controlled

electric heater is installed in the MV-C panels. These can be

equipped with either an internal thermostat that turns off the heater

when it reaches a fixed temperature, or (on the customer’s request) a

thermostat controller, which allows the customer to choose the de-

sired temperature, is installed.

Danger

Before working on the plant, it must be activated in accordance with

the rules of electrical engineering, prevented from restarting, short-

circuited and earthed. Cover or partition off adjacent live plant com-

ponents.

In preparation for the commissioning, the following needs be done:

Check the general condition of the switchgear for possible dam-

age or defects.

Perform a visual inspection of the switchgear, break contacts,

insulating parts, etc.

Check the connection of the main earthing bar to the PE con-

ductor of the installation (in accordance with applicable safety

regulations).

Check the paint for damage and touch it up if necessary.

Remove all material residues, foreign parts and tools from the

switchgear.

Clean the switchgear and wipe the insulating parts with a soft,

dry, clean and lint-free cloth. Remove greasy or sticky dirt.

All covers, etc. removed during assembly and test procedures

must be properly refitted.

Commissioning


6.2 Checks during final assembly on site

When line-ups are installed or when individual panels were partially

dismantled for transportation reasons and the internal medium-volt-

age connections loosened in the process, the following two tests,

which otherwise have already been carried out after final assembly at

the factory, must be repeated on site after assembly:

6.2.1 High-Pot test

The High-Pot test is a test for voltage resistance. It is performed sep-

arately for the medium and low-voltage components.

The built-in components are subjected to a test voltage that is a mul-

tiple of the rated voltage for 60 seconds.

All electronic components that can be destroyed in this test must be

removed beforehand.

6.2.2 Insulation measurement

In insulation measurement (Megger test), the insulation capability of

the electrical lines or the quality of the earthing of the plant is tested

with a high test voltage.

A Megger test (1kVDC) is performed between the three short-cir-

cuited phase conductors and the earth. The result should have an in-

finitely large resistance outcome.

Operating


7. Operating

7.1 Operating the MV-C

Depending on the built-in switching technology, an MV-C control

panel has different display and operating elements. Here only those

operator actions and elements are described which basically may oc-

cur in all versions.

7.1.1 Ensure safety

In accordance with the electrical safety rules the following steps have

to be followed when any maintenance, cleaning or repair work is

done inside an MV-C panel:

1st Activate

Upstream circuit breaker must be switched to switch position

OFF. An existing disconnector must be switched to the switch

position DISCONNECTED.

Figure 47 Activate

Operating


2. Secure against re-starting.

For this purpose, the disconnector can be locked with a padlock

to prevent activation. The key must be stored appropriately.

Figure 48 Secure against reconnection.

3. Check that the equipment is disconnected from the power

supply.

Using a tester, the control panel must be tested in several places

to determine that it is not under voltage. When capacitors are in-

stalled, it is essential to take measurements on both connection

sides of the capacitors after they have been discharged and pos-

sibly short-circuited. The same applies to fuses in the event of

triggering.

Figure 49 Establish voltage-free status.

Operating


4. Earth and short-circuit.

To exclude with certainty that intrinsic voltage can endanger per-

sonnel, the plant must be earthed in the next step and short-cir-

cuited.

This is done by actuating the earthing electrode (1) or it has al-

ready happened when a coupled disconnector and earthing elec-

trode (2) had been actuated. Alternatively, it can be earthed using

an earthing harness.

8. Maintenance / repairs

8.1 General

Caution

Five safety rules of electrical engineering

The five electrical safety rules must be observed during installation,

maintenance or repair work on the products and components de-

scribed in this manual.

See chapter 7.1.1 Ensure safety on page 61 on their practical imple-

mentation.

8.1.1 Preventive maintenance

Maintenance is important to ensure the trouble-free operation and

maximum service life of the switchgear. It includes the following

closely inter-related activities:

Inspection: Determination of the current state or condition

Maintenance: Measures to maintain the specified state or con-

dition

Repairs: Measures to restore the specified state or condition

When any maintenance and repair work is done, the regulations of

the country where the equipment is used must be observed. The

work may only be done professionally by trained personnel who are

familiar with the properties of the respective switchgear, and in ac-

cordance with the applicable IEC safety regulations and the provi-

sions of other technical authorities with other overarching provisions.

It is recommended to commission the IGEL customer service to carry

out the maintenance and repair work listed below.



8.1.2 Intervals for inspection, maintenance and repairs

The time intervals for the maintenance work to be performed always

depend on the operating conditions of the switchgear and especially

from the mode of operation, the number of switching operations with

rated and short-circuit current, ambient temperature, pollution and so

on. We recommend that the equipment is serviced at the appropriate

intervals according to the following table:

In addition to the visual inspection, check that all installed elements

function properly, both mechanically and electrically:

Circuit breaker

Earthing switch

Switchgear



Controls, in particular emergency stop button

Housing elements, doors and their locks

Transducer (visually/acoustically)

8.2.2 Maintenance

Remove corrosion and treat the respective areas with a suitable

agent.

Remove dirt and other types of deposits.

Lubricate the main contacts of the earthing electrode/discon-

nector, etc. with a suitable lubricant.

Lubricate door hinges etc. with suitable lubricants.

Adjust the door locks if necessary. For this purpose, loosen the

screw (2) and adjust the position of the locking pin (3) on the

push rod (1) so that it completely frees the space between the

two plates when open and when closed, reaches through the

top plate.

Secure the screw with thread lock fluid again if necessary.

Figure 51 Door lock adjustment option



Changing the fuses

If the optional built-in medium-voltage fuses have to be changed,

safe conditions in accordance with chapter 7.1.1 Ensure safety on

page 61first need to be created.

A plastic hammer, for example, can be used to release the retaining

clips. The fuses (1) can then be removed from the holders by hand,

and the new fuses – after troubleshooting the cause of the blown

fuses – can be reinserted by hand. Then close the retaining clips

again.

If the fuses have to be removed immediately after they have blown,

special fuse tongs (2) must be used because the fuses are still too

hot to handle them safely!

Figure 52 Medium-voltage fuses and tongs

8.2.3 Check after short circuit

After a short circuit you need to check that the tightening torque of all

the screw connections in the panel is correct; due to the vibrations

caused by the short circuit.

Make contact with IGEL Electric GmbH anyway to agree on the way

forward. If applicable, tests as described in chapter 6.2 Checks dur-

ing final assembly on site from page 58 need to be repeated.

Decommissioning and disposal


9. Decommissioning and disposal

For the final decommissioning of an MV-C control panel, first perform

the steps that are described in chapter 7.1.1 Ensure safety on page

61 .

Then the following needs to be done:

1st After it has been ensured that there is no medium-voltage sup-

ply present, the medium-voltage connections have to be loos-

ened.

2nd 1. Then disconnect the control lines.

3rd 2. Loosen the floor anchorages and, if necessary, the screw

connections of a line-up.

4th 3. Dispose of the individual components of the control panel for

recycling in accordance with the national and/or local regula-

tions.

Attention

Capacitors must be discharged and short-circuited before they can

be dismantled.

Capacitors may contain toxic oils which may not leak out during dis-

mantling and disposal. It is therefore preferable to leave the proper

disposal to a certified specialised company.
