[0002] As we all know, with the increasingly tense energy issues, wind energy, as a new type of clean energy, has attracted more and more attention; due to the rich wind energy resources in Northeast, North and Northwest China, at present, 70% of the total installed capacity of the country is distributed In the above-mentioned areas; obviously, the common feature of the above-mentioned areas is that the temperature in winter is relatively low, and the lowest temperature is even lower than minus 30 degrees Celsius. Therefore, the problem of low temperature is a common problem faced by wind turbines in these areas; through long-term practice, it is found that , the wind turbines in the above-mentioned areas have the following defects: 1. When the external environment temperature is low, freezing weather often occurs, especially in winter rainy or snowy weather conditions, the ice and snow on the blades of the wind turbines The inside of the blade freezes, resulting in changes in the aerodynamic performance of the blades of the wind turbine, unbalanced movement of the rotor rotor, thereby increasing the load on the wind turbine, and even causing defects in the shell of the wind turbine blades to burst; The performance of the running parts of the generator set is reduced, and the maintenance is more troublesome.
