Operation The table below gives the stages of opening :

Stage Description

Start of opening When the moving contact (4) separates from the maincontacts (3), the current is switched onto the arc con-tacts (10). The compression of the (Vp) volume cau-ses the first rise of pressure.

103 4 Vp

Thermal effect When the contacts (10) separate, the arc appears andits energy causes the pressure to rise in the thermalexpansion volume (Vt), closed by the fixed contact rod(11) and the insulating nozzle (12).

12 10 Vt11

Interrupting andassistanceat opening

When the rod (11) comes out of the nozzle (12), thethermal overpressure in the volume (Vt) is releasedcausing an energy blast to occur, just before the cur-rent zero passage, ensuring final quenching of thearc.The (Vp) volume pressure decreases to the ambiantpressure by means of the valve (13) to allow the endof the opening.

Operation, continued The table below gives the continuation of opening stages :

Stage Description

“OPEN” position The arc has been extinguished.The SF6 molecules, separated by the arc, are re--formed instantaneously.Residual gases left over from the interruption opera-tion are absorbed by the molecular sieve, situated atthe base of the pole. A few powdery compounds aredeposited in the form of dust which is quite harmlessfor the circuit breaker.

Special caseof small currents

For small currents (example : operating no--load lines, transformers or ca-pacitor banks), the thermal energy of the arc is too low to provide enough ex-cess pressure.Consequently, the conventional autopneumatic effect developing in the vol-ume (Vp) is used mainly, to blast the arc.

Gas pressure and density

Introduction Theelectrical characteristics of switchgear depend on the density of SF6 gas

i.e. the mass of gas pumped into a compartment of a given volume.

Constanttemperature

At constant temperature, an increase of gas density results in a higher gaspressure against the walls of compartment.

Constant density At constant density, with an fixed compartment volume, the pressurechanges in the same way as the temperature. Since the gas density re-mains invariable owing to the fact that no modification occurs in the quanti-ty of gas or the volume of the relevant compartment, the electrical charac-teristics of the switchgear will remain unchanged.

Conclusion Since it is difficult to measure the gas density directly, it is essential toknow accurately its absolute pressure and temperature.

Pressure measurement

Effective pressure ?

Absolute pressure ?

Absolute pressure = effective pressure + atmospheric pressure

Pressure Description Diagram

Effective

The pressure of SF6 gas is mea-sured by of a standard pressuregaugewitha deformablediaphragmactuating an indicating pointer.One surface of the diaphragm is incontact with the SF6 gas, while theother is in contact with the atmo-sphere. The differencebetween thegas and the atmosphere is thus

measured, taking atmosphericpressure as a reference. This is themeasurement of the effective pres-sure of the SF6 gas.

SF6

Atmospheric pressure

Standard pressure gauge

Absolute

If the deformable diaphragm, onesurface of which is in contact withthe SF6 gas, blocks a volume wherea vacuum has been developed, thepressuregauge measures thepres-sure difference between that of theSF6 gas and thevacuum. Since thelatter is zero, the pressure gaugemeasures the absolute pressure ofthe gas.The absolute pressure of the SF6

gas, independent of atmosphericpressure, reflects the quantity ofgas introduced into the compart-ment and hence its density at thepresent temperature.This is measured by means of an

absolute pressure gauge which isless generally used and more deli-cate than a effective pressuregauge. This is the reason why a ef-fective pressuregauge is used, pro-vision being made for correctionsrequired by atmospheric pressurevariations resulting from atmo-spheric disturbances and differ-ences of elevation.

Measuring density

Pressure units D The international unit pressure is the Pascal (Pa).

D The practical unit is the bar (14.503 p.s.i.)1 bar = 1,000 hPa1 bar = 100 kPa10 bar = 1 MPa

D Standard atmospheric pressure is equal to 101.3 kPa at sea level and anair temperature of 20C (68F).

Measuring density When it is not possible to directly measure density, this may be checkedusing an industrial pressure gauge capable of measuring the effectivepressure.An effective pressure value corresponds to the rated density, determined

for normal atmospheric pressure (101.3 kPa) and an ambient temperatureof 20C (68F).

For eachpressurereading (filling, inspection of densimeter thresholds...), therated effective pressure should be corrected according to the ambient tem-perature and atmosphericpressureof thesiteat thetime thereading is taken.See the module “Calculation of the SF6 gas filling pressure to using thepressure gauge (tool)”.

The real pressure is therefore :

Preal = Prated effective in accordance with temperature + ∆Pp*

* ∆Pp : correction in accordance with atmospheric pressure.

Function D Permanent SF6 gas density monitoring.

D Visual SF6 gas real pressure information (MPa -- psi).

Localization The densimeter is situated onto the bottom of the pole of the circuit--breaker,and joined to the gas volume of the circuit--breaker.

Working The densimeter is fitted with internal contacts. These contacts closesucces-sively if the gas’s density diminishes and determine 2 distinct thresholds.These contacts are wired to the terminalblock inside the cubicle and are usu-ally left at the user’s disposal for the following use :

Theapparatusmust be storedwith itstransport packaging open whilstplacedonbeams ina closed, but ven-tilated, flood--proof place.

Operating device

The operating device should bestored in the same place as the cir-cuit--breaker, these two sub--assem-blies being inseparable. Check thatthe vacuum packaging is leak--tight.

If this has beendamaged, proceedas

follows :D Completely remove the packagingprotection so that air can enterthroughtheventsof therearplate andside panels.

D In order to prevent corrosion dam-agedueto formation of condensation,it is mandatory that the heating circuitbe switched on.

ANY CHANGE OF LOCATIONOF THE APPARATUS(EVEN AFTER COM-

MISSIONING) SHOULD BE DONE AT A REDUCED PRESSURE OF0.3 BAR.

Reminder SF6 envelopes are at rated pressure following the SF 6 gas filling operation.

Parameters Take note of parameters below :

D site altitude, in meters,

D atmospheric pressure of site in kPa,

D site temperature in C.

Checking SF6 gas SF6 pressure values must obligatorily be read on the pressure inspectiongauge (tooling). Pay no attention to indications given by the dialdensimeter on the filling control block (where applicable) ; it is not accurateenough for this inspection.

See the module “Calculation of theSF6 gas filling pressure to using thepressure gauge(tool)”.

The table below gives the steps of checking :

Step Action Comment

1 Measure SF6 gas pressure bymeans of the pressure inspectiongauge (tooling)

Follow the instructions given inmodule ”Filling with SF 6 gas”.

2 Correct pressure found. Follow the instructions given inmodule ”Calculation of the SF 6gas fillingpressure to usingthepressure gauge (tool)”.

Lubrication

Principle No future lubrication will be necessary. The bearings and rollers have been

lubricated in our workshops with special grease :ASEOL SYLITEA 4--018

This grease can easily endure very low temperatures and has an excellentresistance to ageing. So that its qualities are not modifiedduring use, itispro-hibited to :

D Mix this grease with any other lubricant.

D Lubricate later with any other oil.

D Spray parts of the apparatus with a protective liquid against corrosion orwith any kind of lubricating oil.

Mixture with other lubricants can cause the layer of grease to become toohard.

SAFETY SHEET



SF6

Use and Handling


Sulphur hexafluoride (SF6) is a gas which in its basic state is colourless, odourless and tasteless. It is not toxic,but it cannot sustain life. It is a heavy gas that is dispersed slowly into the atmosphere.

In its natural state, SF6 is delivered and stored in pressurized tanks (bottles or spheres) at a pressure ofapproximately 20 bar at 20°C (in its liquid form) and complies with IEC standard 376.

However, under the effect of the electric arc, the SF6 molecules break up and the elements mostly recombineduring cooling either due to extinction of the arc or by regeneration caused by the presence of activeabsorbent charges within the circuit breaker. Various chemical reactions, associated with the volatilization of the materials in contact with the electric arc,

create either fluoridized or sulphurous secondary gas products or solid products in the form of metallic fluoridepowder ; or again, in the presence of traces of water or moisture, hydrofluoric acid or sulphur dioxide.

In the life-cycle of the equipment, SF6 can be observed not only in its pure state, but also in its contaminatedstate :

- the use of new SF6 for filling or adding,

- leaks under normal operating conditions,

- maintenance involving the opening of circuit breakers containing old SF6 (decomposition products),

- abnormal conditions (internal arc fault causing the shielding to break),

- circuit breaker recycling on end of life-cycle.

WORK REQUIREMENTS.

Follow the instructions for the transport of pressurized containers.

The storage of these containers is governed by the same storage regulations as compressed gas bottles :

- keep away from any source of heat and in a cool, dry and well-ventilated area,- always fit a pressure reducing valve.





PS 0004/A 02 1996-03-18 1998-08-12 2 / 3Sheet N° Revision 1st issue Revision date Page

Whilst SF6 in its pure state is not toxic, the decomposition products have varying degrees of toxicity. They may irritate the skin, the eyes and the mucous membranes; and in massive amounts may cause serious lesions(oedema, heart failure, circulatory disorders and unconsciousness).However, very rapidly and before there is any real danger, signs such as a pungent smell, irritation of themucous of the nose, the eyes and the mouth will give a warning and the personnel concerned will havesufficient time to take the necessary safety actions.

Where the gas is used or handled within enclosed premises, ensure adequate ventilation, especially low down.If the gas is inhaled, the area concerned must be evacuated immediately.

Under normal operating conditions, leaks are exceptionally minor and not critical, even when the gas containsimpurities (due to the regenerating filters in the circuit breaker).

Filling and where necessary topping up operations must be carried out using the appropriate tools.

During maintenance operations, or at the end of the life-cycle, dust inside the equipment must be removed by a vacuum extractor and the operator should wear a mask. Gas recovery must be carried out using theappropriate gas recovery equipment.

Gases and decomposition products must be treated and/or disposed of by specialist organizations.

Under extremely abnormal conditions (e.g. break in the shielding) in an enclosed space, individual protectiveequipment is recommended.

Lastly, it is forbidden to smoke, drink, eat or keep food in the vicinity of open SF6 equipment, whether indoors

or outside (harmful dust).





It is essential that both the fitter and the user read IEC Technical Report 1634 regarding the use andhandling of sulphur hexafluoride gas.

Introduction

This manual describes the following manual operations:• Slow closing

• Slow opening

• Manual discharge of closing spring

Manual operations as described in these instructions are not necessary inthe course of installation or in normal circuit breaker operation.

The circuit breaker can be slowly closed or slowly opened as required foradjustment and inspection purposes.

In order to remedy a problem after improper manipulations or in case of

circuit breaker malfunctions, the equipment can be slowly closed or slowlyopened or the closing spring can be manually discharged.

Safety

The 70.00 motor-wound spring operating mechanisms feature state-of-the-art design and high operational reliability. They can nevertheless pose ahazard if used improperly. The circuit breaker operator must therefore ensure that assigned personnel

• Is familiar with locally and nationally applicable safety and accident-

prevention regulations, particularly as applicable to high-voltageswitchgear and other high-voltage equipment

• Is aware of and comply with the contents of these instructions

• Has received technical training on circuit breakers, including operatingmechanisms

• Observes safety instructions affixed to the apparatus

• Has the duty immediately to report any changes that interfere with safety

Necessary conditionsfor performance of manual operations

• The circuit breaker is in open position.

• The circuit breaker is earthed on both sides.

• The control voltage is disconnected.

Safety: general • Manipulations not in compliance with these instructions pose hazards forthe personnel involved as well as for the motor-wound spring operatingmechanism.

• Manipulations on the motor-wound spring operating mechanism that donot comply with the FK 3-X instructions create a danger of death or injuryto the person performing them. Damage to the motor-wound spring op-erating mechanism may also result.

DANGER • Perform only manipulations that comply with the instructions forFK 3-X motor-wound spring operating mechanisms.

Personal safety whenperforming manipu-

lations on the oper-ating mechanism

• The closing spring is charged after the control voltage is disconnected.Inadvertent switching operations are possible while performing manipu-

lations on the operating mechanism even though the control voltage isdisconnected.

• Injury may result from touching parts that are moving.

WARNING • To discharge the springs, use manual releases to open, close andreopen with the control voltage disconnected.

• Spring operating mechanisms with undervoltage releases open immedi-ately when the control voltage is disconnected.

•

This can lead to injury when performing manipulations in the springoperating mechanism.

WARNING • Disable the undervoltage release to prevent unforeseen openingoperations.

• When the motor voltage is turned on, the motor immediately begins towind the closing spring.

• Injury may result from touching parts that are moving and/or spring-driven.

WARNING • When turning on the control voltage, keep body parts away fromparts of the equipment that are moving and/ or spring-driven.

Product safety • If the spring operating mechanism is operated with no circuit breaker, thetotal energy is released inside the spring operating mechanism.

•

Damage to the operating mechanism may result.

CAUTION • Operate the spring operating mechanism only with the circuitbreaker coupled to it.

• If the gas pressure of the circuit breaker is lower than the minimum valuefor mechanical switching operation (listed on the warning plate in thespring operating mechanism), an excessively high energy is released in-side the spring operating mechanism.

• Damage to the circuit breaker and the spring operating mechanism may

result.

CAUTION • Operate the spring operating mechanism only with a circuit breakerhaving a gas pressure higher than the minimum value for mechani-cal switching operation.

• Dust inside the spring operating mechanism can interfere with the func-tioning of moving parts such as latches, rollers and shafts and can impairthe performance of electrical equipment.

• Malfunctions and damage to the spring operating mechanism may result.

CAUTION • Always keep the inside of the spring operating mechanism free of dust. Always close the cabinet door in correct fashion to bar the en-try of dust.

• The use of cleansers, rust-preventing oil or sprays can lead to heavy build-ups of gum.

• This can interfere with the functioning of the spring operating mechanism.

CAUTION • Use only mechanical cleaning aids when performing cleaning

and/or corrective maintenance. If relubrication is necessary, it mustbe carried out in compliance with the FK 3-X lubrication instruc-tions.

• Moisture inside the spring operating mechanism leads to condensationand subsequent corrosion of steel parts.

• Malfunctions and damage to the spring operating mechanism may result.

CAUTION • The heating (anticondensation feature) must always be in opera-tion, regardless of where the circuit-breaker is installed.

Evacuation of SF6 gas apparatus

Principle and

precautions

The table below gives the principle of evacuation of SF 6 gas apparatus and

precautions to take :

Step Action Comment

1 De--energize apparatus, switch--off where applicable and earth.

2 Connect the servicing unit to thegas filling nipple by means of ahose and using an adsorber filter.

3 Suck SF6 gas :

-- Into servicing unit or ,

-- After having taken the ap-propriate safety precautions, ex-

haust the gas outdoors (observethe local regulations on emis-sion).

Where switchgear with consider-able decomposition products isinvolved, exhaust outdoors onlythrough an adsober filter.

4 Fill gas compartment if possiblewith nitrogen or dry compressedair at rated pressure and subse-quently, discharge outdoors (if possible through an adsorber fil-ter).

Opening--up SF6 gas switchgear

Precautions to take At the time of the opening--up SF6 gas switchgear, take the precautions be-

low :

S Open--up SF6 switchgear only after the gas has been evacuated and thepressure inside the apparatus has been reduced to that of atmospheric pres-sure.

S Put the ventilation system in operation or ensure that fresh air circulatesin some other manner when switchgear which contains decomposition prod-ucts is opened (e.g. circuit--breaker).

S Wear suitable fresh air breathing apparatus if there is even the slightestpossibility that personnel working on the equipment could be put in dangerthrough inhalation of hazardous amounts of gas vapor from powdery decom-position products.

S Wear special overalls when working on opened--up SF6 switchgear whichcontains powdery decomposition products. After completing work remove

overalls.

S Avoid stirring--up dust and powder from SF6 switchgear. Difficult to removedust can be removed with dry non--fibrous rags. A vacuum cleaner should beused to remove loose dust. Thevacuum cleaner filter should be able to retainsparticles of a least 1 min size.

S Items (such as rags, vacuum cleaner, throw--away--overalls, gloves, etc.)which come in contact with the decomposition products must be collected andneutralized so that the dust cannot be transferred. Before getting rid of theseitems neutralize in a 3 percent soda solution for 24 hours. verify the degreeof neutralization after 24 hours. When soda is added, no bubbles should beresult. If there are bubbles repeat the neutralization.

S Under all circumstances ensure that the decomposition products neithercome in contact with skin, eyes, clothes, nor that they are swallowed or in-haled. Pay special attention to cleanliness of body, clothes and work--bench.Dust or powder that comes in contact with skin must be washed away withplenty of water.It is advisable to wash face, neck, arms and hands with soap and plenty of water before work--breaks and after stoppage of work.

S Avoid eating, drinking, smoking or storing eatables in rooms or outdoorsnear to opened SF6 switchgear which may contain arc--decomposed powder.

Recapitulation of important instructions

Reminder Pure, non--contaminated SF6 gas is non--poisonous. Electrical discharges

and fault--switching arcs will give rise to different grades of poisonous decom-position products. In small amounts gaseous decomposition products pro-duce -- within seconds and before any poisonous effects can take place --warning symptoms, such as an unpleasant piercing odor, nasal, mouth andeye irritations, which enable working personnel to withdraw to safety. Soliddecomposition products (powdery residues from switching) can cause skinirritations. SF6 is about five times heavierthan air, and in theabsence of turbu-lence, results in the gas collecting just above ground level and causing suf-focation through a deficiency of oxygen.

Importantinstructions

The table below recapitulates the important instructions to follow at the timeof handling of used SF6 gas and decomposition products :

No. Instruction

1 As soon as an unpleasant, piercing odor from decompositionproducts becomes perceptible leave the substation room with-out delay. enter the room only after thorough ventilation or whenwearing suitable oxygen breathing masks (with filtering or freshair device).

2 After disturbances, enter the substation room only after havingthoroughly aired the room or when wearingindependent of ambi-ent--air operating oxygen breathing masks, or alternatively, afterverifying by measurement that the ambient air contains at least17% volume of oxygen, especially if, one has to reckon with theconcentration of SF6 in hazardous amounts.

3 Enter rooms located below, and connected with the substation--rooms after thorough ventilation only, or when wearing oxygenbreathing masks which operate independent of the ambient--air,or alternatively, after having verified by measurement that theambient air contains at least 17% volume of oxygen.

4 Ensure that the room ventilation operates satisfactorily, whilstmaintenance work is being performed on SF6 switchgear (dis-charging and filling of gas, opening and cleaning of equipment).

5 When working on opened SF6 switchgear protect skin againstcontact with gas and avoid swallowing or inhaling of gas. Ensurebody, clothing and work--bench cleanliness. Wear special work--overalls and after completion of work discard latter.

6 Wash skin which comes in contact with powder deposits withplenty of water. Before work--breaks and after work wash face,neck, arms and hands thoroughly with soap and plenty of water.

7 Do not stir--up powder deposits resulting from arc--switching.Remove sticky powder with dry rags. Use suitable vacuumcleaner with paper--filter to remove loose powder. Discard useditems and filter--bags in such a manner that powder deposit doesnot spread. Before discarding neutralize used items.

8 Avoid eating, drinkingand storing eatables inrooms with openedSF6 switchgear which contains powder deposits.
