电力机车网压波动故障的原因分析及应对措施

The cause analysis and countermeasures for catenary voltage fluctuation fault of electric locomotive

针对朔黄铁路交流传动电力机车因网压异常波动导致机车卸载的故障现象,结合线路环境及机车实际运用情况,通过跟踪电力机车的网压监测情况及相关电路原理分析,系统性研究了网压波动的原因,对类似电力机车网压波动故障提出应对措施及合理化建议。

Aiming at the fault phenomenon of traction unloading caused by abnormal fluctuation of catenary voltage of AC drive electric locomotive on Shuohuang Railway,this paper systematically studies the causes of catenary voltage fluctuation by analyzing the line environment and the actual situation of locomotive,tracking the monitoring situation of catenary voltage of electric locomotive and analyzing the circuit principle,and puts forward countermeasures and reasonable suggestions for similar faults of catenary voltage fluctuation of electric locomotive.
