General

The AirSwitch series of switching and isolatingapparatus consists of medium voltage airinsulated isolators, suitable for use in metal-enclosed switchboards (rotary version) andfor wall-mounting (hinged version).

DESCRIPTION

They are used in secondary distribution substa-tions for supplying lines, power transformers andring networks.

The switchboard rotary isolators are available intwo versions: AM type switch-disconnectors AR and AS type rotary isolators.

The hinged wall-mounted switch-disconnectorsare the GS and IMC types for voltages up to 24 kV.

Operating mechanisms

One of the following operating mechanisms canbe used on the Airswitch isolators, according totheir foreseen use.

Operating mechanism with dependentoperation

This allows manual closing and opening with theoperator deciding the operating speed.

1) Operating mechanism onexceeding dead centre

2) Stored energy operatingmechanism for GS/IMCswitch-disconnector.

Stored energy operating mechanism withindependent operation

This allows rapid manual closing with operationindependent of the operator, obtained by meansof a spring charged over the dead centre.

During the closing operation, a separate spring isautomatically charged which stores the energy foropening.

Isolator opening can be carried out by means of:

operating lever

knob

shunt opening release (applied on the operatingmechanism itself)

release system activated by the fuse striker(even in the case of a single blown fuse).

This type of operating mechanism is normally in-stalled in AM/Y, GS/Y and IMC/Y isolators.

Closing or opening is obtained by activating theoperating lever.Withdrawal of the lever from its coupling is onlypossible after completion of the closing or openingoperation.This type of operating mechanism is installed onAS-AR isolators and on AT earthing switches.

Operating mechanism with independentoperation on exceeding dead centre

This allows rapid manual closing and opening

with operation speed independent of the operator,obtained by means of a single spring. Closing oropening is carried out by charging this spring untilthe dead centre is exceeded.This type of operating mechanism is normallyinstalled in the AM/X, GS/X, and IMC/X isolators.On request, it is available in the version with motoroperator for AM and IMC isolators.

DESCRIPTION

Fuses

The isolators can be combined with fuse-holderframes suitable for mounting fuses according toDIN Standards which allow protection of powerand instrument transformers.

Fields of application

The rotary and hinged isolators are used insecondary distribution substations as feederswitching and/or isolating apparatus, fortransformer power supply (in combination

with protection fuses or circuit-breakers), etc.

Compliance with Standards

The Airswitch isolators comply with Italian CEI 17-9/1 (file 1672) Standards, International IEC 60265-1 and CENELEC HD 355.1 S2 Standards.The AM and GS switch-disconnectors are derivedfrom apparatus which has obtained Enel (ItalianElectricity Board) approval.

Operating temperature

The operating characteristics of the Airswitch iso-lators do not alter within a range of ambient tem-peratures from 5 C to + 40 C.

Main technical characteristics

Frame. Thisconsists of press-bent steel sections,welded, galvanised and shaped to make the struc-ture particularly sturdy.

Moving contacts. In the rotary type isolators,the rotating body consists of 3 copper bars,covered with insulating material with finned profile(to increase surface insulating distances).The isolator moving contacts are placed at theend of these bars.

In the hinged isolators, the moving contacts areof the jointed type with double blades; the contactpressure is ensured by special springs and bythe self-tightening action of the moving contactpassed through by current.

Insulators

In the rotary type isolators the three upper insu-lators act as a support for the upper fixed contactsand allow direct fixing of the main busbars.The lower insulators act as a support for the lowerfixed contacts and allow direct connection of themedium voltage cables.

The lower insulators of the AM switch-disconnec-tors also incorporate the pistons for the air blastand act as the support for the fixed arcing con-tacts.

In the hinged isolators, apart from being thesupport for the main fixed and arcing contacts,the blowing nozzles and the terminals, the threeupper insulators also incorporate the pistons forthe air blast. The lower insulators support theterminals of the main moving contacts.

Insulating parts

The insulators are made of self-extinguishingepoxy resin or polyester glass, and have a finnedprofile with extended exhaust lines to ensurewithstanding of surface discharges.

Breaking principle

In both the rotary and hinged switch-disconnec-tors, on opening there is compression of the airby means of the pistons contained in the insulatorcylinders. Thanks to the generation of a blast ofcompressed air which comes out through special

1) Insulator prepared for con-nection of the main busbars ofthe switchboard.

2) Detail of the lower insulatorwith piston and blast nozzleof the AM type switch-disconnector.

3) Upper insulator of the GS/IMCswitch-disconnector.

4) Arc extinguishing action by

means of air compression.

nozzles, the arc is cooled and deionised onseparation of the contacts. This means there is agradual increase in the arc resistance which de-termines extinction.The piston movement is synchronised with themovement of the main contacts of the isolator sothat the greatest flow of air is ensured at the mo-ment of contact separation and therefore arc ex-tinction is ensured.

Degree of protection

The frame of the AM and AR/AS rotary isolatorsis constructed so that, when inserted in a switch-board, metallic segregation between the busbarcompartment and the feeder-circuit-breakercompartment is always ensured, with degreeof protection IP20.

Earthing

Contact earthing is carried out by activatingthe earthing switch. Furthermore, in the rotary typeisolators, in the open position, the moving contactsare automatically earthed.

1 Crosspiece withcapacitive insulators

This device consists of ametal crosspiece onwhich three voltage sen-sors (capacitor dividers)are installed preset forconnection in a suitabledetection circuit.

The possible combina-tions are indicated below.

1A Crosspiece with capacitive insulators (insula-tors H = 260 mm) (GS)

1B Crosspiece with capacitive insulators (insula-tors H = 215 mm) (GS)

1C Crosspiece with capacitive insulators (insula-tors H = 170 mm) (GS).

Isolator operation

The hinged isolators are mainly used in open sub-stations and are normally placed at a height of 2-4metres.To be able to operate these isolators, it is neces-sary to use a transmission operating mechanismand/or an insulated rod operating mechanism.To be able to construct a transmission operatingmechanism (earth and/or feeder), the followingcomponents are required (see figure on the fol-lowing page).

Back of switchboard or wall operatingplate (2).The wall operating plate is fixed onto the samewall as the isolator at a height easily accessibleto the operator.The switchboard operating plate is fixed to a

wall of the switchboard and allows transmissionof the operation as far as the isolator.

Key lock for operating plate (3).This is a mechanical device which allows theoperating plate to be locked in the open orclosed position.

Operating levers (4) for transmission orinsulated rod operating mechanism.The GS/IMC series of isolators are always pre-set to take both types of operating mechanism.Selection of the type of operating mechanismconsequently implies the type of lever which the

isolator must be fitted with.

Transmission rod (5).This is normally supplied with a diameter of 3/4and a length of three metres. It is used to makethe mechanical connection between the operat-ing plate and the lever for the isolator operatingmechanism. The final length must be set up bythe customer.

Intermediate supports (6).There are two types of intermediate supports,one with a simple lever and one with a 90lever.The intermediate support with simple lever al-

lows the bending moments of the transmissionrod to be discharged, permitting particularly longtransmissions.The 90 intermediate support allows operationof an isolator lying on a surface parallel to theoperating plate.

Feeder shaft support (7).This is used to guide the movement of the shaftextension (8).

Shaft extension with sleeve (8).This allows extended operating mechanismshafts to be made.

with intermediate support, for wall-mounted iso-

lator with feeder shaft extension.

Shunt opening release

This is an electromechanical devicewhich, following energisation of anelectromagnet, activates the operat-ing mechanism release lever makingthe isolator open. This application isonly compatible with stored energyoperating mechanisms (GS/IMC ... /Y).N.B. The shunt opening release must al-ways be combined with a set of 5 or 10auxiliary contacts of the line-side isolator(see kit No. 9).
