文摘Grew up in this paper, in view of the urban rail transit ramp section, from the viewpoint of energy saving and increase contact line voltage index, the paper puts forward a kind appropriate location in the traction power supply division set up, the concrete implementation plan of the downlink power supply in parallel. At the same time, it puts forward a corresponding bilateral jump does not affect both the dc traction power supply system protection function, safe and reliable to achieve multichannel parallel protection scheme and the running safety and energy saving effect was analyzed.
