过电压引起电力机车放电间隙击穿原因分析

针对电气化铁路过电压导致电力机车放电间隙击穿，造成牵引变电所跳闸的现象，进行电力机车升降弓和通过接触网关节式分相的过电压试验，对过电压引起电力机车放电间隙击穿放电问题的原因进行分析。

Analysis of Reasons of Discharging Gap Breakdown of Electric Locomotive Caused by Overvoltage

With respect of discharging gap breakdown of electric locomotive caused by overvoltage of electrified railways which will induce to the tripping of traction substation, on basis of the pantograph rise of the locomotive and overvoltage test for passing through the overlapped phase break of the overhead contact line being performed, the paper analyzes the reasons of discharging gap breakdown of electric locomotive caused by overvoltage
