The invention discloses a train power supply cabinet with a grounding resistance loop and a passenger train. The power supply cabinet comprises a first power supply cabinet LG1 and a second power supply cabinet LG2 which are respectively connected with a train load, wherein the first power supply cabinet LG1 comprises a first alternating current power supply circuit and a first grounding resistor GRe1, one side of the first alternating current power supply circuit is connected with a vehicle load to provide a first path of alternating current for the vehicle load, and the other side of the first alternating current power supply circuit is grounded through the first grounding resistor GRe1; the second power supply cabinet LG2 comprises a second alternating current power supply circuit and a second grounding resistor GRe2, one side of the second alternating current power supply circuit is connected with the vehicle load to provide a second path of alternating current for the vehicle load, and the other side of the second alternating current power supply circuit is grounded through the second grounding resistor GRe2. According to the train power supply cabinet, the two alternating current power supply circuits are electrically independent from each other, and the problem that electric leakage cannot be detected correctly is solved by adding a grounding resistor to a grounding loop.

    本发明公开了一种具有接地电阻回路的列车供电柜以及铁路客车,所述供电柜包括:分别与车辆负载相连接的第一供电柜LG1及第二供电柜LG2;其中,所述第一供电柜LG1包括第一交流供电电路以及第一接地电阻GRe1,所述第一交流供电电路一侧与车辆负载相连接以为车辆负载提供第一路的交流电,另一侧通过所述第一接地电阻GRe1接地;所述第二供电柜LG2包括第二交流供电电路以及第二接地电阻GRe2,所述第二交流供电电路一侧与车辆负载相连接以为车辆负载提供第二路的交流电,另一侧通过所述第二接地电阻GRe2接地。本发明所述的列车供电柜两路交流供电电路之间电气上相互独立且通过在接地回路添加接地电阻的方式解决了无法正确检测出漏电的问题。
