【摘要】 电力系统中使用真空断路器切除无功补偿用并联电容器时,容易产生重燃过电压,严重影响并联电容的安全运行。笔者对10kV系统中切除并联电容器时所产生的重燃过电压进行了模拟计算,着重分析了影响重燃过电压大小的因素,并研究了利用MOA对并联电容器进行过电压保护的效果。更多还原

【Abstract】 In a10kV distribution system,when shunt ca-pacitors are switched off by vacuum circuit breakers,restrike overvoltage often occurs.In this paper,the restrike overvolt-ages are calculated,the factors that may affect the magnitude of restrike overvoltage are analyzed,and the effectiveness of using MOA to limit restrike overvoltages is studied.更多还原
