OPERATING MECHANISM FOR SWITCHING DEVICE SUCH AS GROUND SWITCH OF MEDIUM-VOLTAGE SWITCHGEAR Russian patent published in 2004 - IPC

FIELD: operating mechanisms of switching devices.

SUBSTANCE: proposed operating mechanism has manually controlled ground-conductor shaft disposed in stationary switchgear chamber and joined through actuating mechanics to driving sleeve of switchgear chamber that takes rotary motion and can be brought in connection in definite way with switching module shaft mounted for rotation within draw-out switching module. Interlocked state is initiated due to axial draw-out of module shaft beyond switching module outline. In order to close separating contact switching module is interlocked with switchgear chamber by means of separator shaft.

EFFECT: facilitated control of modular switchgear devices.
