Abstract

The embodiment of the invention provides a railway vehicle roof structure, a railway vehicle body and a railway vehicle. The railway vehicle roof structure comprises a pantograph installed on the topof a railway vehicle, a vacuum circuit breaker arranged at the top of the railway vehicle andconnected with the pantograph, a transient inductor arranged at the top of the railway vehicle and connected with the vacuum circuit breaker, and a voltage transformer installed at the top of the railway vehicle and connected with the transient inductor. The transient inductor is located between the voltage transformer and the two-position end of the railway vehicle in the longitudinal direction of the railway vehicle, the transient inductor is connected with a high-voltage cable, and the high-voltagecable is unwound from the two-position end. The railway vehicle roof structure, the railway vehicle body and the railway vehicle provided by the embodiment of the invention are used for solving the problem that in the prior art, a high-voltage cable routing path is too long, and the effects of shortening the routing path, reducing the weight of the cable and reducing the wiring cost are achieved.

Description

technical field [0001] The invention relates to the field of rail vehicles, in particular to a rail vehicle roof structure, a rail vehicle body and a rail vehicle. Background technique [0002] In the current field of rail vehicles, the cables of the pantographs usually installed on the roof need to go from the two-position end across the distance of one car to the one-position end for off-line. Such a wiring method will result in long wiring paths, difficult wiring, heavy weight and high cost of cables. Moreover, this wiring method will cause high-voltage cables to pass under the pantograph, and the toner powder dropped during the operation of the pantograph will easily damage the cables. In view of this, the wiring layout of the high-voltage cables on the roof of the rail vehicle needs to be redesigned. Contents of the invention [0003] Embodiments of the present invention provide a rail vehicle roof structure, a rail vehicle body, and a rail vehicle, which are used t...
