The present invention relates to an interlock device of withdrawing a vacuum circuit breaker. More particularly, the present invention relates to an interlock device of withdrawing a vacuum circuit breaker to prevent the withdrawal of the vacuum circuit breaker when the ground switch of the vacuum circuit breaker is on. An interlock device of withdrawing a vacuum circuit breaker according to an embodiment of the present invention includes a handle door which is allowed to access to the driving shaft of a ground switch by horizontal movement; an interlock shaft which is rotated by the movement of the handle door; an interlock block which is rotatably connected to the interlock shaft; a stopper which restricts the driving spindle of the circuit breaker; a latch which is installed to the stopper interlock shaft and restricts the motion of the stopper; and a stopper restriction lever which is installed to an end of the stopper interlock shaft and receives the operation force of a user. The latch is interrupted by the interlock block when the ground switch is on, so that it is impossible to release for the stopper. |
