摘　　要：华北-华中联网工程调试期间,在辛安侧5061断路器投切辛嘉线空载线路试验中,A相重合闸三相分闸后发生1次重击穿,C相发生3次重击穿,引起河北南网500 kV系统多处出现过电压。对此,根据测试结果进行了详尽分析。During the commissioning of North China Grid and Central China Grid lnterconnection, 5061 circuit breaker on Xin＇an side was operated to test the Xin＇an Huojia line which carries no load, 1 repeated breakdown was happened on phase A, 3 repeated breakdowns for Phase C. The breakdown caused over voltage in many parts of 500 kV system in South Hebei Power Grid. A detailed analysis was made based on the test results.
