摘要
通过对500kV香山变电站500kV开关防跳回路出现故障现象进行分析,阐述了开关本体防跳回路与操作箱控制回路配合时的动作原理,指出了开关本体防跳回路与操作箱控制回路之间的寄生回路问题,并通过分析研究找出了解决方案。
Through the analysis of anti-tripping circuit fault for a 500kV substation Circuit Breaker, this article was described the action principle of cooperation between Breaker body anti-tripping circuit and operation cabinet control circuit. It was also found out the problem of parasitic circuit between them, and given out a solution scheme by analysis.
