摘要
针对消弧线圈接地电网中普遍存在的谐振过电压问题,分析了正常运行及断线故障时各种补偿方式下位移电压的大小,指出了消弧线圈采用过补偿运行方式是防止产生谐振过电压的有效措施。
The paper presents the most efficient means to prevent the occurrence of resonance overvoltage often happening in extinction coil earthed networks,namely,overcompensation pattern,with the help of analysiging of shift voltages in formal operation and broken wire condition.
