Summary:The invention belongs to the technical field of high-power doubly-fed asynchronous wind driven generators, particularly relates to a wire leading method for electrical connection of a rotating structure, and provides the following scheme aiming at the problems of open welding of a joint of a rotor winding and a connecting piece under the action of alternating stress and potential safety hazards of a rotor cable to the ground in the background technology. According to the wire leading method for electrical connection of the rotating structure, preparation is conducted through the wire leading device, the wire leading device comprises a rotating shaft, and a connecting piece is connected into the rotating shaft. The advantages of the cable lead and the copper bar lead are combined, the cable lead is adopted in the rotor winding and before entering the shaft hole, centrifugal force generated by high-speed rotation of the rotor and alternating stress generated when the rotating speed of the rotor changes are coun
