一起断路器控制回路缺陷处理及分析

Treatment and Analysis of a Circuit Breaker Control Circuit Defect

断路器控制回路断线是继电保护专业经常处理的缺陷。断路器控制回路中串联了较多节点,尤其是合闸回路,因此故障也常发生在合闸及其相关回路。文章所述缺陷出现在分闸回路,详述缺陷处理及分析过程,并研究了断路器辅助开关接线。

The disconnection of circuit breaker control circuit is a defect that relay protection specialty often deals with.Many nodes are connected in series in the circuit breaker control circuit,especially the closing circuit,so the fault often occurs in the closing and its related circuits.The defects described in this paper appear in the opening circuit,and the defect treatment and analysis process are described in detail,and the auxiliary switch wiring of the circuit breaker is studied.
