摘　　要：蓄电池电力工程车辅助逆变控制系统安装的C_(4)电容存在可能被击穿的风险,若C_(4)电容击穿,辅助变流器内部的保护熔断器FU1将熔断,导致辅助变流器中断正常工作,高压主控回路出现安全联锁封锁控制,主控回路将不允许再次闭合,机车不能自牵引运行。通过深入分析电气控制回路故障原因,采取措施后可预防重大安全故障发生。There is the risk of breakdown existing in the C_(4)capacitance installed for the auxiliary inverter control system of battery electric engineer.In the case of C_(4)capacitance breakdown,the internal fuse FUl of auxiliary converter is fused resulted in normal work interrupt.High-voltage main control circuit use safety interlock block control so that it cannot be switched on again.Automatic traction operation cannot be carried out for the locomotive.Through analyzing the fault reasons of electrical control circuit deeply,major safety failures can he prevented after taking measures.
