摘　　要：笔者分析了高压断路器开合并联电抗器的原理和开断过程以及过电压情况,结合试验标准要求和EMTDC模拟计算结果,讨论了电抗器开合试验的试验回路的设计和试验方法,给出了实际的试验正常波形和重燃波形。最后模拟并计算了试验截流过电压和重燃过电压,提出了使用氧化锌避雷器限制回路暂态过电压的办法。In this paper, the principle and process of shunt reactor switching are analyzed. By analyzing the demand of the standard and the simulated results, the test circuit and method of shunt reactor switching are discussed, and the actual test result as well as normal waveform and reignition waveform are presented. In further, the test chopping overvoltage and reignition overvoltage are analyzed by applying EMTDC simulation; the limited transient overvoltage method, using ZnO attesters, is proposed.
