摘要
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。
This paper analyses the mechanism of widening arc and over-voltage which occur when the electric locomotive passes the articulated phase insulator. A conclusion is given that widening arc also exists even if the breaker is off, and resonance over-voltage is the objective factor which breaks the discharge gap down.
