Design and Implementation of Breaker Operating Circuit with Trip Circuit Status Monitoring

Breaker operating circuit plays an important role in the breaker operation system.And its main function is to issue the circuit breaker tripping and closing pulse,prevent breaker jump phenomenon,and monitor on the status of breaker tripping and closing circuit.A reasonable designed operating circuit can effectively improve the reliability of the breaker operation.This paper describes the functions of breaker operating circuit and the main part of the circuit.Furthermore,a practical solution and its application for the issue of the trip circuit monitoring are proposed and discussed.
