Embodiment Construction

[0041] The technical solutions of the present invention will be further explained below in conjunction with the drawings and embodiments, but the following content is not intended to limit the protection scope of the present invention.

[0042] Such as figure 1 Shown, the overall structure of the present invention is schematic. 1 shown in the figure is the crankshaft of the rotor, 2 is the shaft drum of the rotor, 3 is the magnetic pole of the rotor, and the magnetic pole 3 is fixed on the shaft drum 2 by a fixing member. The shaft drum 2 is hollow, with ventilation holes 4 at both ends. The cooling gas is input into the motor through the exhaust window 9 and the heat dissipation cooling device 12, and passes through the shaft drum ventilation holes 4 to pass through the shaft drum to perform heat dissipation circulation inside the rotor. The lower vent vents heat out of the generator body. 5 is the rotor, 6 is the generator casing, 7 is the stator magnetic pole, 8 is the wi...

Abstract

The invention discloses a multi-winding asynchronous change-pole generator comprising a rotor, a stator and a radiation cooling device. The energy generated by the rotor is transmitted to the stator through magnetism and is converted into voltage and current by the stator to be transmitted to a grid; an electric brush of the rotor and a slip ring of the generator as well as a rotor inverter of a double-feed generator are not needed, wherein the rotor adopts a mouse cage type structure; a rotor shaft comprises two parts of a crankshaft and a shaft drum which are fixed together; the shaft drum adopts a hollow manner; air holes are arranged at both ends of the shaft drum; the magnetic pole of the rotor is fixed on the shaft drum; the stator is a multi-winding change-pole type stator structure; the mode of connection is a two-winding asynchronous change-pole mode and a multi-winding asynchronous change-pole model containing more than two windings; the number of the pole pairs of the stator is changed by changing the mode of connection of the winding coil; and the radiation cooling device adopts a shaft drummer type rotor cooling radiation mode. The invention is suitable for the characteristic of wind power natural environment and meets the grid requirement.

Description

technical field [0001] The invention relates to a generator belonging to the technical field of wind power generation, in particular to a multi-winding asynchronous pole-changing generator. Background technique [0002] Wind energy is a clean and renewable resource, and its use has been paid more and more attention by countries all over the world. With the development of the world's energy crisis, the use of wind kinetic energy as a new energy source for the development of modern society has become a hot spot in social development. [0003] After searching the literature of the prior art, it is found that the existing propeller-type wind power generators and vertical axis wind power generators at home and abroad include the generator set with the existing Chinese patent application number ZL200430067146.5, the patent application number 200610157277.0, the application number / The synchronous generator with patent number 200410073317, the high-power double-pivot double-fed b...
