电气线路故障是电传动内燃机车的常见故障，以其偶发性强，复杂多样，处理困难成为内燃机车的一大难题，也是危及机车运用安全的一大隐患。长期以来，不少科研单位、院校及生产现场都对电气线路故障的检测进行了攻关，研制一些检测设备，从不同角度检测解决电气线路故障，收到
Electric line failure is a common failure of electric drive diesel locomotives. With its sporadic, complex and diverse difficulties in handling, it has become a major problem for diesel locomotives and a serious risk to the locomotive safety. For a long time, many scientific research institutes, colleges and production sites have carried out research on the detection of electrical circuit faults, developed some testing equipment, detected and solved the electrical circuit faults from different angles, and received
