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.

    本发明实施例提供了轨道车辆车顶结构、轨道车辆车体及轨道车辆。轨道车辆车顶结构包括:受电弓,安装在轨道车辆的车顶部;真空断路器,安装在所述轨道车辆的车顶部与所述受电弓连接;瞬态电感,安装在所述轨道车辆的车顶部与所述真空断路器连接;电压互感器,安装在所述轨道车辆的车顶部与所述瞬态电感连接,其中,沿所述轨道车辆的纵向方向,所述瞬态电感位于所述电压互感器及所述轨道车辆的二位端之间,所述瞬态电感连接有高压线缆且所述高压线缆由所述二位端下线。本发明实施例提供的轨道车辆车顶结构、轨道车辆车体及轨道车辆,用以解决现有技术中高压线缆走线路径过长的问题,实现缩短走线路径、减轻线缆重量且降低布线成本的效果。
