摘　　要：断路器操作回路是断路器动作控制的重要环节,它的主要作用是对断路器发出跳、合闸脉冲,防止断路器出现"跳跃"现象,对断路器跳、合闸回路在线监视。设计合理的断路器操作回路可以有效提高断路器动作的可靠性。文中叙述了断路器操作回路的作用以及各个回路的功能,提出解决跳闸回路全监视的具体实现方法,并对于实际应用进行了讨论。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.
