分析了电力机车通过关节式电分相装置时,发生拉弧和过电压现象的故障机理,得出机车断电过分相也会产生拉弧和谐振过电压击穿放电间隙的结论。
The fault mechanism of arcing and overvoltage occurred when the electric locomotive passes through the joint phase splitter, and the conclusion is drawn that the over-phase of the locomotive power-off can cause arc-striking and resonance over-voltage breakdown discharge gap.
