The invention discloses a transition system suitable for communication of a special rail return-flow system and a running rail return-flow system in urban rail transit, a return-flow conversion area is arranged between the running rail return-flow system and the special rail return-flow system, and a train performs return-flow mode switching in the area; the two backflow systems are respectively provided with an independent traction power supply; positive buses of the two traction power supplies respectively supply power to the overhead line system, and the overhead line system is shared in the backflow exchange area to supply power to the train; the two backflow system traction power supply negative buses are electrically isolated, the special rail backflow equipment is connected with the special backflow rail, and the walking rail backflow equipment is connected with the walking rail; the special backflow rail is electrically isolated from the walking rail; a running rail transition area is arranged on the side, connected with the backflow conversion area, of the special rail backflow system, steel rails in the running rail transition area are installed in an insulating mode, and insulating knots are arranged at the two ends of the steel rails in the running rail transition area. The through grounding conductor is electrically isolated at the interface of the backflow transition area and the running rail transition area.

    本发明公开了一种适用于城市轨道交通专用轨回流系统与走行轨回流系统贯通的过渡系统,在走行轨回流系统与专用轨回流系统之间设置回流转换区,列车在此区域内进行回流制式切换;两个回流系统均设有独立的牵引供电电源;两个牵引供电电源正母线分别向接触网供电,其中在回流交换区内共用接触网向列车供电;两个回流系统牵引供电电源负母线之间电气隔离,专用轨回流设备连接专用回流轨,走行轨回流设备连接走行轨;专用回流轨与走行轨之间电气隔离;专用轨回流系统在连接回流转换区侧设置走行轨过渡区,走行轨过渡区内的钢轨绝缘安装,走行轨过渡区内的钢轨两端设置绝缘结;贯通接地导体在回流转换区与走行轨过渡区接口处电气隔离。
