摘　　要：双流制牵引供电系统在市域(郊)铁路中应用,标志着干线铁路、城际铁路、市域(郊)铁路和城市轨道交通的“四网融合”。本文通过对双流制牵引供电系统特点、双流制列车牵引传动系统工作原理、双流制列车通过中性段切换原理、双流制牵引供电系统中性段处弓网故障及列车中性段切换故障原因进行分析,采用静态、动态、交直流切换检测试验,预防双流制列车在中性段发生故障,提高双流制牵引供电系统运行安全性和可靠性。The application of dual current traction power supply system in urban(suburban)railways marks the“four network integration”of mainline railways,intercity railways,urban(suburban)railways,and urban rail transit.The paper analyzes the characteristics of the dual current traction power supply system,the working principle of the dual current train traction transmission system,the principle of dual current passing through the neutral section switching,the pantograph faults at the neutral section of the dual current traction power supply system,and the reasons for the neutral section switching faults of the train.Static,dynamic,and AC/DC switching inspection tests are applied to prevent the faults in the neutral section of the dual current train and improve the safety and reliability of the dual current traction power supply system operation.
