Problems solved by technology

[0005] In the prior art, whether the wind turbine is cooled by air or by air and water, air, or air and water can only be passed into the cooling equipment of the wind turbine according to the preset flow rate to supply the wind power. The generator cooling equipment cools the wind turbine, but it cannot automatically adjust the cooling capacity of the wind generator according to the amount of heat generated by the wind generator during the cooling process

Abstract

The invention provides cooling equipment and a cooling method for a wind-driven generator. The equipment comprises a cooling device and a transmission part, wherein the cooling device is connected with a rotating shaft of the wind-driven generator through the transmission part; the transmission part is used for driving the cooling device to operate when the rotating shaft of the wind-driven generator operates; and the cooling device is used for cooling the gas of the wind-driven generator. By the cooling equipment and the cooling method for the wind-driven generator, the cooling quantity of the wind-driven generator can be automatically adjusted according to the magnitude of heat generated by the wind-driven generator.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generator cooling device and a cooling method. Background technique [0002] During the power generation process of the wind turbine, its generator winding will generate a lot of heat due to the large current flowing through it. According to the design output power, the cooling power of the wind turbine can be tens of kilowatts to hundreds of kilowatts, which will lead to wind power generation. The temperature of the machine rises. Since excessive temperature will affect the normal operation of the wind turbine, it is very important to cool the wind turbine during the power generation process. [0003] figure 1 It is a schematic diagram of a wind power generator cooling method in the prior art, such as figure 1 As shown, the wind power generator cooling device 201 introduces the hot air generated by the generator winding 202 of the wind power generat...
