The invention relates to the technical field of train power supply, and particularly discloses a high-voltage system of a double-flow system rail transit vehicle, which comprises a power receiving part arranged at the top of a vehicle, and an alternating current processing part, a direct current processing part and a traction part which are respectively connected with the power receiving part, the power receiving part comprises a pantograph, an alternating-current high-voltage electrical appliance box and an alternating-current and direct-current conversion switch; the alternating current and direct current conversion switch is used for switching when 25KV alternating current received by the pantograph from a pantograph net is converted into 1500V direct current or the 1500V direct current is converted into the 25KV alternating current. The rail transit vehicle can operate in the direct current power supply environment and can also operate in the alternating current power supply environment, the double-current system rail transit vehicle becomes possible, and the complex power supply environment can be fully utilized for rail vehicle arrangement.
本发明涉及列车供电技术领域,具体公开了一种双流制轨道交通车辆高压系统,包括设置在车辆顶部的受电部分,以及分别与受电部分连接的交流处理部分、直流处理部分和牵引部分;所述受电部分包括受电弓、交流高压电器箱和交直流转换开关;所述交直流转换开关用来在受电弓从弓网上接收25KV交流电变为1500V直流电或者从1500V直流电变为25KV交流电时进行切换。本发明使轨道交通车辆既能够在直流供电环境中运行,又能够在交流供电环境中运行,使双流制轨道交通车辆成为可能,能够充分利用复杂的供电环境进行轨道车辆布置。
