摘　　要：分析双源无轨电车集电头带有高压电的现象,结合双源无轨电车高压电气原理和在线式绝缘检测仪的工作原理,发现集电头带电是由于触发绝缘检测仪工作引起的,不会影响整车系统和高压用电安全。The authors analyze the high-voltage electrification phenomenon of a dual-source trolleybus collector head, combine the high-voltage electrical principle of dual-source trolleybus and the working mechanism of insulation detector, they find out that the electrification phenomenon of trolley bus collector head is caused by the triggering of the insulation detector work, which does not affect the safety of the vehicle system and high voltage electricity.

关 键 词：双源无轨电车 集电头 带电 绝缘检测
