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.

Switchgear Type SIMOSEC up to 24 kV, Air-Insulated, Extendable
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.

Switchgear Type SIMOSEC up to 24 kV, Air-Insulated, Extendable
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.
