The utility model relates to a wiring structure of three-phase cable terminal rows of a wind driven generator. The three-phase cable terminal rows of the generator are arranged and scattered at different heights; and wiring holes on the terminal rows and outlet holes on walls of a junction box are in one-to-one correspondence. Therefore, power cables led out from the three-phase cable junction box can be arranged and divided into groups; and each group includes respective three-phase cables. On the basis of the arrangement, the cables are led to related equipment at the tower bottom from the generator, so that the three-phase cables are not bent and not intersected mutually during the installation process in the junction box of the wind driven generator. And because the three-phase cables are not intersected mutually during the process of laying from the generator junction box to the converter cabinet at the tower bottom of the generator set, the currents flowing through all the cables of the same phase in the three-phase cables of the wind driven generator can be distributed uniformly and the induced voltage value can be minimized, thereby prolonging the service life of the power cables of the wind driven generator and improving the reliability of the running of the wind driven generator.
