摘要:
An embodiment of a switchgear has: a closing shaft; a main lever fixed to the closing shaft and associated with a movable contact; a cutoff spring; a sub-shaft; a sub-lever and a latch lever which are connected to the sub-shaft; a roller pin mounted to the leading end of the latch lever; a latch; a latch returning spring for urging the latch; a latch pin fixed to the latch; and a ring mounted to the latch pin so as to be movable in the radial direction of the latch pin. In the closed state, the roller pin presses the leading end of the latch. In power cutoff operation, latch is pulled so as to permit rotation of the latch, engagement between the roller pin and the leading end of the latch is disengaged, and the sub-shaft is rotated by urging by the cutoff spring.
