The invention provides a CRH(China Railway High-speed) train traction transmission power supply system which comprises an alternating current-direct current-alternating current traction converter which comprises a single-phase alternating current input port and a three-phase alternating current output port. Wherein a first end of the single-phase alternating current input port is used for being incontact with an overhead line system powered by low-voltage single-phase alternating current through a first conducting circuit to receive power, a second end of the single-phase alternating currentinput port is used for being in contact with a steel rail through a second conducting circuit, and the three-phase alternating current output port is used for being connected with a traction motor. And a vehicle-mounted traction transformer is not arranged between the first end of the single-phase alternating current input port and the overhead line system. The self-weight of the train can be effectively reduced, the space on the train is saved, and the axle weight of the train is balanced.
