The invention discloses a rail locomotive backflow rail switching system which comprises a contact net, a traction unit, a walking rail, backflow rails, a first backflow device and a short circuit device used for electrically connecting the backflow rails at the two adjacent ends in a backflow discontinuous area. One end of the traction unit is electrically connected with the contact net, and the other end is electrically connected with the backflow rails through the first backflow device; the system further comprises a walking rail, a second backflow device, a first switch unit and a second switch unit. One end of the first switch unit is electrically connected with the other end of the traction unit, and the other end is electrically connected with the walking rail through the second backflow device; one end of the second switch unit is electrically connected with the short circuit device, and the other end is electrically connected with the walking rail. Due to the adoption of the technical scheme, compared with the prior art, the locomotive does not need to stop to replace the power supply mode when passing through the discontinuous area of the special backflow rail, the locomotive still stably passes through the discontinuous area of the special backflow rail in the previous contact net power supply mode, and the operation efficiency of the locomotive is improved.

    本发明公开了一种轨道机车回流轨切换系统,包括接触网、牵引单元、行走轨道、回流轨、第一回流装置以及用于将回流间断区中相邻两端回流轨电连接的短接装置;牵引单元的一端与接触网电连接,另一端通过第一回流装置与回流轨电连接;还包括行走轨、第二回流装置、第一开关单元和第二开关单元;第一开关单元的一端与牵引单元的另一端电连接,另一端通过第二回流装置与行走轨电连接;所述第二开关单元的一端与短接装置电连接,另一端与行走轨电连接。由于采用了上述技术方案,与现有技术相比,本发明使机车在通过回流专用轨间断区时不需停车更换供电模式,仍沿用之前的接触网供电模式平稳通过回流专用轨间断区,提升机车作业效率。
