摘　　要：针对SS4改型电力机车运行中主电路接触器处于闭合位时,因逻辑控制单元LCU错误输出或LCU外线短路,二位置转换开关反向鼓将进行转换,由此会造成牵引电机逆电环火故障。分析了故障原因并提出了技术改进措施。When the main circuit contactor of SS_4 modified electric locomotive is in closed position, the two-position changeover switch reverser is converted due to an error output or outside short-circuits of the logic control unit LCU, which will cause reverse flashover in electric traction motor. The fault reasons are analyzed and improvement measures are proposed.
