Embodiment 1
[0025] figure 1 It is a structural schematic diagram of the grounding system of the rail train of the embodiment of the present application; figure 2 for figure 1 The partial enlarged view of the structure of the grounding system shown.
[0026] Such as figure 1 and figure 2 Shown, the grounding system of the rail train of the embodiment of the present application comprises:
[0027] The gear box grounding device 120 is assembled on the collector ring box outside the gear box of the power bogie; wherein, the gear box grounding device 120 is used to collect leakage current from the collector ring in the collector ring box, and from the collector The leakage current collected by the electric ring is conducted to the track ground through the wheel set assembled by the gearbox;
[0028] A grounding resistor 110, one end of the grounding resistor 110 is connected to the car body of the train through a wire, and the other end of the grounding resistor 110 is used to connect t...
Embodiment 2
[0086] The rail train of the embodiment of the present application includes the grounding system of the first embodiment.
[0087] figure 1 The rail trains are dual-stream rail trains, figure 2 yes figure 1 A partial enlargement of the . The marshalling structure of the dual-stream rail train is 4 motor cars and 4 trailers, the motor cars are 2, 4, 5, and 7 cars, and the trailers are 1, 3, 6, and 8 cars. The traction transformer 12 is arranged on the trailers 3 and 6 respectively, and the traction converter 22 is arranged on the trains 2, 4, 5 and 7. Each car has two bogies and four axles. The train structure is as follows: figure 1 and figure 2 shown.
[0088] Protective grounding:
[0089] Such as figure 1 and figure 2 As shown, a 100mΩ grounding resistor 110 is respectively connected in series between each car body of the motor car 2, 4, 5, and 7 cars and the gear case grounding device 120 of the train to form the car body of the train. The grounding resistor 110...
