摘　　要：该文基于南京地铁2号线地铁电客车近年来发生的高压电路故障,从理论计算及现场情况对故障原因进行分析与探讨。由于在运营过程中,部件自身原因导致功能失效,引发电路中的电流异常,进而引发系统性故障。通过分析得到故障原因并调整相应的维护策略,以此来避免或减少该类故障的发生。Based on the high-voltage circuit faults that have occurred in subway buses of Nanjing Metro Line 2 in recent years,this paper analyzes and discusses the causes of the faults based on theoretical calculations and field conditions.During operation,the component itself causes functional failure,causing abnormal current in the circuit,which in turn causes systemic failure.The cause of the failure is analyzed and the corresponding maintenance strategy is adjusted to avoid or reduce the occurrence of such failures.
