The invention discloses a double-current system city domain train traction high-voltage control system and method. The system comprises a power supply system detection device, a system selection switch, a roof switch, an alternating-current main circuit breaker, a high-voltage isolation switch, a direct-current high-speed circuit breaker and a traction high-voltage control unit. The power supply system detection device is connected with a contact network, and is used for judging whether a current high-voltage system of a train is in a DC 1500V direct current mode or an AC 25kV alternating current mode; and in a DC1500V direct current mode, the system selection switch and the roof switch are closed, and the DC1500V high-voltage circuit is connected to the direct current input end of the traction converter box body through the direct current high-speed circuit breaker. The invention provides a traction high-voltage control system and a traction high-voltage control method for a double-current urban train, which can control the on and off of a high-voltage switch according to the detected current traction power supply system parameter, thereby realizing the full-automatic switching of the traction power supply system of the urban train between direct current (DC) 1500V and alternating current (AC) 25kV.

    本发明公开了一种双流制市域列车牵引高压控制系统及方法,系统包括供电制式检测装置、系统选择开关、车顶开关、交流主断路器、高压隔离开关、直流高速断路器和牵引高压控制单元;所述供电制式检测装置与接触网相连,所述供电制式检测装置所述用于判断列车目前高压系统处于DC1500V直流模式还是AC25kV交流模式;在DC1500V直流模式下,所述系统选择开关与车顶开关闭合,DC1500V高压电路通过直流高速断路器连接至牵引变流器箱体的直流输入端。本发明提供一种双流制市域列车牵引高压控制系统及方法,能够根据检测到的当前牵引供电制式参数,控制高压开关的闭合与断开,从而实现市域车辆的牵引供电制式在直流DC1500V和交流AC25kV之间的全自动切换。
