The invention discloses a branch line polarity conversion circuit of an APM direct current traction power supply system. A vehicle depot line is connected with a main line through two branch lines; the two branch lines are respectively provided with a non-electric area; the two ends of the non-electric area disconnect a circuit through electric sections; the vehicle depot line is connected with the direct current bus through two vehicle depot circuit breakers which are connected in parallel; the electric connection polarities of the two vehicle depot circuit breakers are opposite, and logic interlocking is carried out. By the adoption of the technical scheme, circuit polarity conversion of the whole vehicle depot is achieved, departure and collection operation can be more continuous, the driving scheduling efficiency is improved, and the method is suitable for automatic garage returning and departure road crossing; a driving indicating lamp is arranged to intuitively prompt a driver of a track electrification state; a short-circuit fault caused by human factors can be avoided through the arrangement of the non-power area; the electrified state of the track is transmitted to a signal system, and when the track state does not meet the conditions of automatic train receiving and departure, the train can stop and wait in front of a non-electrified area.

    本发明公开了一种APM直流牵引供电系统岔线极性转换电路,车辆段线路与正线分别通过两条岔线连接;在两条岔线上分别设置无电区;无电区的两端通过电分段将电路断开;车辆段线路分别通过两个并联的车辆段断路器与直流母线连接;两个车辆段断路器的电连接极性相反,并进行逻辑互锁。采用上述技术方案,车辆段整体实现电路极性转换,可以使发车和收车运行更连续,提高行车调度效率,并且适用于自动回库和发车交路;行车指示灯的设置可以直观提示司机轨道带电状态;无电区的设置可以避免人为因素导致的短路故障;支持将轨道带电状态传给信号系统,当轨道状态不满足自动收车和发车的条件时,列车会在无电区前停车等待。
