The present invention discloses a branching structure of a roof trunking and a railway vehicle. The branching structure comprises a first double-layer wire duct and a second double-layer wire duct, ahigh-voltage compartment and a low-voltage compartment are arranged between the first double-layer wire duct and the second double-layer wire duct, and each of the first double-layer wire duct and thesecond double-layer wire duct comprises a lower-layer wire duct and an upper-layer wire duct; a high-voltage wire enters the lower-layer wire duct of the first double-layer wire duct, then enters thehigh-voltage compartment, and then enters the upper-layer wire duct of the second double-layer wire duct; a low-voltage wire enters the lower-layer wire duct of the second double-layer wire duct, then enters the low-voltage compartment, and then enters the upper-layer wire duct of the first double-layer wire duct. The branching structure can solve the problems of high-voltage and low-voltage interchange electromagnetic interference in roof branching, insufficient cable offline height space in the slot of the offline port and sealing of the offline port.
本发明公开了一种车顶线槽的分线结构及轨道车辆,所述分线结构包括分第一双层线槽和第二双层线槽,所述第一双层线槽和第二双层线槽之间设有高压隔仓和低压隔仓,所述第一双层线槽和第二双层线槽均包括下层线槽和上层线槽;高压线进入所述第一双层线槽的下层线槽,接着进入所述高压隔仓,然后进入所述第二双层线槽的上层线槽;低压线进入所述第二双层线槽的下层线槽,接着进入所述低压隔仓,然后进入所述第一双层线槽的上层线槽。该分线结构可以解决车顶分线中存在的高低压互换电磁干扰、下线口在线槽内时线缆下线高度空间不足及下线口密封问题。
