摘要
在高压真空断路器投切电抗器时,会产生操作过电压(截流过电压、多次重燃过电压、三相同时断开过电压),造成电抗器频繁损坏。通过对多起同类事故的现象及波形分析,阐明了操作过电压产生的机理及影响操作过电压的各种因素,并有针对性地提出了相应的解决方案。
When vacuum high-voltage breaker switches in reactors,the switching overvoltage（cut-off overvoltage,multiple reignition overvoltage,three-phase simultaneous-off overvoltage）will appear to break reactors frequently.Through the analysis on the phenomenon and waveform of many similar faults,the mechanism of overvoltage＇s occurance and many factors which affect the switching overvoltage are presented,together with the corresponding solutions.
