Abstract

The asynchronous generator consists of the chassis, the formed stator winding, the stator iron core and the rotator. Special points are that the chassis possesses a water cooling twin layers; the wind tube is buried within this twin layers; two sets of twin formed stator windings with different pole numbers are adopted; A centrifugal fan is set on the rotator. The end of the formed winding is colligated with a soft end hoop. The two windings are separated by a discontinuous colligation with the double soft end hoops. The axis directional vent holes are made on the rotator core. The invention ensures a stable, safe, reliable and efficient running. Its power can reach 1300 / 250 KW.

Description

technical field

[0001] The invention relates to a generator, in particular to a high-power double-speed double-winding asynchronous wind power generator. Background technique

[0002] At present, the supporting motors of the main models of 600kW and 750kW wind turbines are double-winding air-cooled asynchronous generators. In order to improve the design and manufacture level of wind turbines and keep up with the development trend of large-scale wind turbines, MW-level two-speed double-winding wind turbines are used as one of the main models of stall-type wind turbines. The structure of the existing general asynchronous generator is not suitable for the MW-level wind asynchronous generator involved in the present invention. It is specifically manifested in that the general two-speed double-winding wind power generator adopts an air-cooled cooling structure, and the inner fan and the outer fan on the rotor generate relatively Large wind friction red...
