Buried-type contact rail power supply system

The utility model discloses a buried-type contact rail power supply system which comprises a plurality of conducting rails and a plurality of insulating rails, wherein the conducting rails and the insulating rails are distributed on a ground buried-type support at intervals, the ground buried-type support comprises a plurality of supporting members, the ground buried-type support is buried underground and positioned between two travel rails on which a train travels, and the upper surfaces of the conducting rails and the upper surfaces of the insulating rails are exposed on the ground. The conducting rails are powered on or off through a head-line power distribution system, so that the conducting rails on which the train travels are powered on to supply power to the train and the conducting rails on which no train travels and the conducting rails which the train passes are powered off. The buried-type contact rail power supply system provides a novel power supply mode to the urban rail traffic, and is not only applied to the closed loop or the non-closed loop urban rail traffic lines but also applied to the non-closed loop urban rail traffic lines with strict requirements for landscape.
