A movement sensing device for a vacuum circuit breaker, wherein the vacuum circuit breaker includes a push rod assembly coupled to a movable electrode of a vacuum interrupter to raise up or lower down the movable electrode, wherein the movement sensing device comprises:
- a sensor module spaced apart from the push rod assembly and facing toward one side of a rod housing;
- and
- a sensing target disposed on one side of the push rod assembly and facing toward the sensor module, wherein the sensing target includes:
- a slit body coupled along a longitudinal direction to one side of the rod housing;
- a slit plate protruding outwardly along a longitudinal direction from an outer face of the slit body;
- and
- a plurality of sensed slits passing through the slit plate.
A vacuum circuit breaker comprising:
- a vacuum interrupter having:
- a fixed electrode fixedly disposed in an insulating container and having a fixed contact at one end thereof;
- and
- a movable electrode having a movable contact at one end thereof, wherein the movable contact is in contact with or is removed from the fixed contact, wherein the movable electrode received in the insulating container so that the movable electrode ascends or descends;
- a main circuit having a housing receiving therein the vacuum interrupter;
- a push rod assembly including:
- a push rod coupled to an opposite end of the movable electrode to raise up or lower down the movable electrode;
- and
- a rod housing for accommodating therein one end of the push rod;
- and
- a movement sensing device including:
- a sensor module installed to be spaced apart from the push rod assembly and disposed to face toward one side of the rod housing;
- and
- a sensing target disposed on one side of the push rod assembly and facing toward the sensor module, wherein the sensor module detects movement of the sensing target, wherein the sensing target includes:
- a slit body coupled to one side of the rod housing and extending in a longitudinal direction thereof;
- a slit plate protruding outwardly from an outer face of the slit body and extending in the longitudinal direction of the slit body;
- and
- a plurality of sensed slits extending through the slit plate.
