摘要
电力系统断路器辅助开关在实际运行过程中,常会出现转换不到位、绝缘性能下降、辅助接点烧坏等故障情况。本文针对一起220kV线路断路器拒动进行分析和处理,提出一些可能的改进措施,确保电网安全平稳运行。
The auxiliary switch of the circuit breaker in the power system often has change-over fault,low in insulating property and auxiliary contact burning during practical operation. The paper puts forward some improved measures for circuit breaker no-operation of 220 kV line,ensuring network safety operation.
