Abstract
A circuit-breaker power impulse controller is used for the power control in the circuit breaker of the power distribution equipment. The circuit is that: the commercial power is commutated into an electromagnetic coil of the circuit breaker and then through the monitoring circuit of the coil; and through a power conversion circuit by voltage reduction, wave filtering and voltage stabilizing, as well as through the power monitoring circuit, the voltage comparison circuit and the monostable circuit; and through the switch-off and switch-on impulse monitoring circuits. Each time of switch off or switch on, the monostable circuit will produce a 50ms impulse so as to trigger the field-effect transistor communicated and supply power for the electromagnetic coil of the circuit breaker with reliable switch off and switch on. The utility model can avoid the coil burning of the traditional circuit breaker due to long time switch off and switch on; and also fundamentally eliminate the skipping phenomenon of circuit breaker off, on, off, on... The utility model has monitoring and instructing functions, including the surveillance and instruction of power, switch off and on impulse and electrical shutdown of coil, so as to provide effective means of inspection for troubleshooting.
Description
Technical field
