| 摘 要： | 为解决高速动车组行车途中发生车头照明灯熄灭不能重新自启状况，在排除高压供电线、380 V 母线、
负载侧影响后，将故障原因锁定在110 V 母线系统及网络控制系统使断路器跳闸; 综合运用计算机控制、变频
调压、传感器测量等技术，结合上位机控制，搭建成一套测试系统，经验证，该系统能快速寻找出故障源。

| Abstract: | In order to solve the problem that the headlights of the high-speed EMUs( Electric Multiple Units) can
not be restarted during the driving，the faults are locked in the 110 V bus system and the network control system
activates the circuit breaker after removing the influence of the high-voltage power supply line，380 V bus and
load side． Using computer control，frequency conversion voltage regulation，sensor measurement and other
technologies，combined with host computer control，a set of test systems is built． After verification，the system
can quickly find out the source of the fault． |
