Doubly-fed asynchronous wind generator

Details:

The company introduced the production technology of 1.5mw~2.0mw doubly-fed asynchronous wind turbine generator from Germany vem company.

The design of this series of products is rigorous, and the process guarantee measures are strict; the box structure and air-to-air cooling mode are adopted; the unique slip ring structure and the preloaded insulated bearing structure ensure the good running state and extremely low fault of the generator. Rate; fixed and rotor are made of low-pressure vacuum pressure immersion paint (VPI) process, high electrical strength and mechanical strength.With its compact structure, light weight, low noise, high efficiency and stable performance, it has been recognized by the market.Since it was put into production in 2008, it has produced nearly 4,000 sets of double-fed wind turbines. It has been put into operation in various wind farms, and the users have reported good results. It is one of the main models in China's wind power market.On this basis, the company has developed a variety of models such as high altitude and salt spray prevention.Among them, high-altitude wind turbines can reach an altitude of 3,800m, and nearly 300 of them are now operating normally in various wind farms.

The 1.6mw doubly-fed asynchronous generator produced by the company has passed the quality certification of ge company and has become a qualified supplier of ge company. It has been supplied in batches and exported overseas.
