MOTION SENSING DEVICE FOR VACUUM CIRCUIT BREAKER AND VACUUM CIRCUIT BREAKER COMPRISING SAME

摘要

The present invention relates to a motion sensing device for a vacuum circuit breaker and a vacuum circuit breaker comprising same. In the present invention, the motion sensing device for a vacuum circuit breaker is provided with a push rod assembly coupled to a movable electrode of a vacuum interrupter to elevate or lower the movable electrode, wherein the motion sensing device comprises: a sensor module spaced apart from the push rod assembly and arranged to face a side of a rod housing; and a sensing unit installed on a side of the push rod assembly and arranged to face the sensor module that senses the movement of the sensing unit.
