接触网电分段电压差产生电弧现象的研究分析

Research and Analysis of Arc Phenomenon Caused by Electric Voltage Difference in Catenary

近年来电气化铁路多次发生机车通过接触网电分段时产生电弧现象,烧伤承力索、接触线,甚至造成接触网断线事故,对电气化铁路安全运营造成一定影响。论文通过对接触网电分段产生电弧现象原理进行讨论,分析电压差产生电弧的原因,并提出一些改进措施。

In recent years,the arc phenomenon occurred many times when the train passing the overhead line system electric sectioning in electrified railways,it burns the bearing cable and contact lines,even causes the catenary failure,causes certain influence for the safe operation of electrified railway.Based on the analysis of principle of arc phenomenon in catenary electric sectioning,paper analyzes the reasons of arc phenomenon,and puts forward some improvments.
