The normally opened contact of coil L1, shunt opening coil L1 are connect with device for under-voltage releasing equipment, and the signal output end of controller 101 is connected by triode
The contact switch J1 of contact relay, relay is connected in the electric power loop of shunt opening coil L1.
Using the under-voltage detection function on controller 101, the case where detecting voltage, operation principle is as follows：
1, when detecting electric voltage exception situation, controller 101 exports a signal and the power supply of shunt opening coil L1 is connected, and comes
Driving coil is attracted that circuit breaker tripping will be made.
2, when detection voltage is normal, controller 101 does not send out signal.
The coil anti-paralleled diode D3 of relay can be formed into a loop after relay power-off, consume excess energy in time.
Device for under-voltage releasing equipment structure used by the present embodiment is applicable to DW45 breakers.
