CABINET OF COMPLETING DISTRIBUTING APPARATUS Russian patent published in 2004 - IPC

FIELD: electrical engineering, namely locking cabinets of complete distribution apparatuses.

SUBSTANCE: cabinet includes housing with door; circuit breaker provided with shaft supporting disc and with two grooves; actuating mechanism with locking device of shaft of actuating mechanism; locking lever which rests by its one end upon shaft of circuit breaker and by its other end upon supporting plate. One end of rod spring-loaded relative to housing of cabinet is connected through arm with locking lever. Other end of spring loaded rod is jointly connected with locking yoke having horizontal groove and mounted with possibility of rotation in vertical plane. At side of lateral surface of locking yoke stop is secured to shaft. Said stop has roller and it engages by its one end with horizontal groove of locking yoke. Other end of stop engages with cam mounted on drive shaft of movable contacts of actuating mechanism. Lever is mounted on shaft of stop; said lever through tie rod is jointly coupled with latch engaging with stopper of mechanism for freely releasing actuating mechanism. Switch is mounted on housing of cabinet; said switch may engage with pressure adjustable bolt arranged on locking yoke. Apparatus does prevents turning on and off circuit breaker when actuating mechanism is turned on, inhibits operation of circuit breaker when door is open, provides possibility for testing operation capability of actuating mechanism at open door and turned off circuit breaker.

EFFECT: enlarged functional possibilities of cabinet.
