Abstract

The embodiment of the invention provides a rail vehicle roof structure, a rail vehicle body and a rail vehicle. The roof structure of the rail vehicle includes: a pantograph installed on the roof of the rail vehicle; a vacuum circuit breaker installed on the roof of the rail vehicle and connected to the pantograph; a transient inductor installed on the roof of the rail vehicle The roof of the rail vehicle is connected to the vacuum circuit breaker; the voltage transformer is installed on the roof of the rail vehicle and connected to the transient inductance, wherein, along the longitudinal direction of the rail vehicle, the transient inductance is located at the Between the voltage transformer and the two-position terminal of the rail vehicle, a high-voltage cable is connected to the transient inductance, and the high-voltage cable is disconnected from the two-position terminal. The rail vehicle roof structure, rail vehicle body, and rail vehicle provided by the embodiments of the present invention are used to solve the problem of excessively long routing paths of high-voltage cables in the prior art, to shorten the routing paths, reduce the weight of cables, and reduce the The effect of wiring costs.

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...
