摘要

A time before a cutoff force of a spring is released in cutoff operation of a switchgear is reduced and high operation stability is obtained. The switchgear has: a closing shaft (81); a main lever (11) fixed to the closing shaft and operatively associated with a movable contact; a cutoff spring; a sub-shaft (70); a sub-lever (71) and a latch lever (72) which are connected to the sub-shaft (70); a roller pin (72a) mounted to the leading end of the latch lever (72); a latch (91); a latch returning spring (91a) for urging the latch 91); a latch pin (91b) fixed to the latch (91); and a ring (52) mounted to the latch pin (91b) so as to be movable in the radial direction of the latch pin (91b) and having an inner diameter greater than the outer diameter of the latch pin (91b). In the closed state, the roller pin (72a) presses the leading end (102) of the latch (91). In power cutoff operation, latch (91) is pulled so as to permit rotation of the latch (91), engagement between the roller pin (72a) and the leading end (102) of the latch (91) is disengaged, and the sub-shaft (70) is rotated by urging by the cutoff spring.
