110kV断路器重合后加速跳闸失败分析及处理

Analysis and treatment of accelerating trip failure after reclosing 110kV circuit breaker

介绍了断路器在模拟线路永久故障传动过程中110kV断路器重合后加速跳闸失败事件,对此事件进行了深度分析,并找出了原因,提出整改方案,以及对保护调试过程中应注意的细节等有关问题进行了探讨,并提出了加强保护调试过程管理的建议。

This paper introduces the failure event of accelerating tripping of 110kV circuit breaker after reclosing in the process of simulating permanent fault transmission of transmission line,analyzes the event in depth,finds out the causes,puts forward the rectification scheme,discusses the details that should be paid attention to in the process of protection commissioning,and puts forward suggestions for strengthening the management of protection commissioning process.
