The invention relates to the technical field of vehicle cables, in particular to a railway vehicle high-low voltage cable cross routing structure and a railway vehicle, a high-voltage box and a low-voltage box are arranged on the surface of a vehicle body and are communicated with a vehicle body cavity, and a high-voltage cable is connected into the high-voltage box from the outside of the vehicle body and is connected into the vehicle through the high-voltage box; a low-voltage cable is connected into the high-voltage box from the outside of the vehicle body, penetrates through the vehicle body cavity to be connected into the low-voltage box, and is connected into the vehicle through the low-voltage box, so that the high-voltage cable located outside the high-voltage box and the low-voltage cable located in the vehicle body cavity are arranged in a crossed mode. Thus, the high-voltage cable and the low-voltage cable are isolated and shielded through the vehicle body cavity, electromagnetic interference caused when the high-voltage cable and the low-voltage cable are crossed is avoided, and normal transmission of vehicle signals is guaranteed. And the high-voltage box and the low-voltage box provide space for wiring of the vehicle body, so that the wiring mode of the vehicle body is simplified, maintenance is facilitated, and consistency of wiring modes of different vehicles is realized.
本发明涉及车辆线缆技术领域,尤其涉及一种轨道车辆高低压线缆交叉走线结构及轨道车辆,通过在车体表面设置高压箱和低压箱,高压箱和低压箱连通车体型腔,将高压线缆由车体外部连接至高压箱内,并由高压箱连接至车内;将低压线缆由车体外部连接至高压箱内,并贯穿车体型腔连接至低压箱内,通过低压箱连接至车内,使位于高压箱外部的高压线缆与位于车体型腔内的低压线缆交叉设置。这样,高压线缆与低压线缆通过车体型腔隔离屏蔽,避免了高压线缆与低压线缆走线交叉时的电磁干扰,保证车辆信号正常传输;且高压箱和低压箱为车体接线提供了空间,简化了车体走线方式,便于检修,实现了不同车辆走线方式的一致性。
