The utility model discloses a fixing structure for a rotor winding outgoing line of a high-power wind driven generator. The contradiction that the inner diameter of the rotor winding outgoing line of a high-power motor and the inner diameter of a hollow hole in the shaft end of the motor are limited is solved. The leading-out wire of the rotor of the high-power doubly-fed asynchronous wind driven generator is changed from a traditional cable to a copper bar, and the requirement of large output current can be met by using the copper bar with a small cross section due to the fact that the conductive density of the copper bar is large, so that the problems that the diameter of the leading-out wire is required to be large, and the aperture of the hollow shaft end cannot be increased due to limitation are solved; in the center hole copper bar lead mode, a rotor winding lead-out wire is connected with a lead-out wire copper bar in a center hole through an L-shaped adapter, the lead-out wire copper bar in the center
