(3) beneficial effect
The invention provides a kind of breaker closing locking device, possesses following beneficial effect：
(1) present invention is by setting electromagnet, magnet coil, fixed seat, dynamic iron core, locking key, having contact with, in operation, when
When electromagnet obtains electric, magnet coil produces magnetic force and inhales dynamic iron core upwards, and triggering the combined floodgate push rod of combined floodgate can just press, and otherwise can
Cause circuit breaker failure, electromagnet not it is electric, the dynamic iron core of electromagnet is in stretching state, and combined floodgate push rod is by the dynamic iron of electromagnet
Core stops can not be movable, causes locking key movable, can not complete feed motion, if atretic body is made because line fault loses locking
With then when line current is excessive, overcurrent protective device top can produce larger magnetic force by the absorption of armature one end moment in overcurrent
Protector top, and the armature other end then will have contact with jack-up by lever, locking key moment makes upper touch by pulling back for back-moving spring
Point separates with lower contact, and then overcurrent protective device now has contact with homing while prop up locking key, rise because of power-off and without magnetic force
Act on, while can be lifted by pressing to have contact with the other end and will have contact with, locking event resolves to locking.
(2) present invention is by setting Current Voltage to detect alarm, when the electric current by breaker is excessive or voltage is inclined
Pick-up current voltage detecting alarm equipment alarm when excessive from normal value, reminds staff, and staff can thus decision circuit
Failure cause, and on-call maintenance is carried out, so as to also reduce the probability of staff's maloperation, protection staff safety.
