Operating mechanismfunctions

Motor operating mechanism1)(M1 *)

In the case of the motor operat-ing mechanism, the closingspring is charged by means ofa motor and latched in thecharged position (the springcharged indication is visible).Closing is effected either bymeans of an ON pushbutton ora closing solenoid. The closingspring is recharged automati-cally (for auto-reclosure).

Manual operating stored-energy mechanism

The closing spring is chargedby means of the supplied handcrank until latching of theclosing latch is indicated(= spring charged indication).

Subsequently the vacuumcircuit-breaker can be closedeither manually or electrically.The closing spring can be re-charged manually. The possibil-ity to close is thus stored oncemore (for auto-reclosure).

Manual spring-operatedmechanism(= spring CLOSED,stored-energy OPEN)

The closing spring of the vacuumcircuit-breaker is charged bymeans of the supplied handcrank until the vacuum circuit-breaker closes. Subsequentlyeither manual or electrical open-ing is possible.

Vacuum circuit-breakers withspring-operated mechanism arenot suitable for auto-reclosure.

Three-position switches as three-position switch-disconnectors or disconnectors

Common features

Metal-enclosedLocated in a

gas-insulatedswitchgear vessel

Switch positions:CLOSED-OPEN-EARTHED

No cross insulationbetween phases

Three-position switchwith air-insulatedprimary connectionsfor busbar and feeder

Operation via a

gas-tight welded-inbushing in the front ofthe switchgear vessel

Mode of operation

The switch shaft with themoving contact piecesrotates inside the cham-ber containing the fixedcontact pieces.

Compression vanes,which rotate in conjunc-tion with the switchshaft, divide the arcingchamber into two sub-

chambers each of whichchanges in conjunctionwith the rotation.

During the switchingmovement, the compres-sion vanes generate apressure difference be-tween the subchambers.The SF6gas flowsthrough a nozzle, causesa directional blow-out ofthe breaking arc andquenches it rapidly.

Interlocking is not neces-sary as the CLOSED

and EARTHED func-tions cannot be imple-mented simultaneously.

Manual operatingmechanism

Standard:As detachable levermechanism

Option: Design accordingto VDEW recommenda-tion Association ofGerman Power Stations VDEW e.V.

Spring-operated mecha-nism

For ring-main paneltypes RK and RK1

For all three-positionswitches (except in panel

types TR and TR1)Spring-operated-/stored-

energy mechanismFor transformer paneltypes TR and TR1 as wellas for busbar voltage me-tering panel type ME31-F

The three-position switch isoperated via a rocker withmetal bellows which isgas-tight and welded at theswitchgear vessel.

Motor operatingmechanism(option)

The manual operating me-chanisms can be equippedwith motor operating mecha-nisms both for the three-position switch-disconnectorand for the three-positiondisconnector.

Operating voltages for motoroperating mechanisms: 24, 48, 60, 110, 220 V DC 50/60 Hz 110 and 230 V AC

Electrical operation:

Standard: Remote opera-tion (applied to terminal)

Option: Local operationby momentary-contactrotary control switch

Shunt release(option)

Spring-operated/stored-en-ergy mechanisms can beequipped with a shunt re-lease. Remote electrical trip-ping of the three-positionswitch-disconnector is possi-ble via the magnetic coilof the shunt release, e.g.transformer overtemperaturetripping.

To avoid thermal overloadingof the shunt release in theevent of a continuous signalthat may be applied, theshunt release is switched offvia an auxiliary switch whichis mechanically coupled withthe three-position switch-disconnector.

Auxiliary switch(option)

Each operating mechanismof the three-position switch-disconnector can be option-ally equipped with an auxil-iary switch for the switchposition indication: 1NO + 1NC for

Short-circuit/earth-faultindicator (option)

The ring-main feeders canbe equipped with a 3-phaseshort-circuit or earth-faultindicator:

Optical signal when a pre-selected pickup value isexceeded

With ring-type sensors

Display panel, withdraw-able housing, dependingon the type

Short-circuit pickup values:e.g. 400, 600, 800 or

1000 AOption: Remote electricalindication via contact (1NO +1NC contact, passing con-tact), applied to terminal

Ready-for-service indicator(option for three-positionswitch)

Self-monitoring; easy toread

Independent of tempera-ture and pressure varia-tions

Independent of site altitude

Only responds to changesin gas density

Option: Alarm switch1NO contact

Mode of operation

For the ready-for-service indi-cator, a gas-tight measuringbox is installed on the insideof the switchgear vessel.

A coupling magnet, whichis fitted to the bottom endof the measuring box, trans-mits its position to an outsidearmature through the stain-less steel switchgear vessel.This armature moves theready-for-service indicator ofthe switchgear.

While changes in the gasdensity during the loss ofgas, which are decisive forthe insulating capacity, aredisplayed, temperature-dependent changes in thegas pressure are not. Thegas in the measuring box hasthe same temperature asthat in the switchgear.

The temperature effect iscompensated via the samepressure change in both gasvolumes.
