For the long-time running that realizes that wind-driven generator is efficient, stable, safe, need the necessary cooling method of configuration in wind powered generator system, work in certain temperature range to guarantee parts such as gear-box, generator and control frequency variator.At present forced air cooling and water-cooling pattern are generally adopted in the cooling of these parts, wherein forced air cooling is applicable to that power is lower than the small power generation unit of 750kW, and, then need adopt the mode of recirculated water cooling could satisfy the requirement of cooling off for the wind-powered electricity generation unit of power greater than 750kW.Along with wind power generating set further striding forward to the maximization direction, the heat that produces in its running will sharply increase, cooling system has been proposed more harsh requirement, the traditional type of cooling will be difficult to reach the demand of cooling, very be necessary to develop the wind powered generator system based on other type of cooling for this reason.
Summary of the invention
The purpose of this invention is to provide that a kind of refrigerating capacity is big, regulating power is strong, good stability, can satisfy the wind-driven generator of the employing vaporization cycle cooling of high-power cooling requirement.
A kind of wind-driven generator that adopts the vaporization cycle cooling, its cabin lid is contained on the stand, in the lid of cabin, lower velocity shaft is housed, gear-box, the gear-box heat exchanger, high speed shaft, the control frequency variator, control frequency variator heat exchanger, generator, the generator heat exchanger, the cooling medium heat exchanger, cooling medium, recycle pump, the cooling medium intake pipe, the cooling medium return pipe, wherein generator and gear-box are installed in the stand two ends respectively, and it is continuous by high speed shaft, gear-box also links to each other by the lower velocity shaft wind wheel outer with being positioned at the cabin lid, the gear-box heat exchanger, control frequency variator heat exchanger, the generator heat exchanger is installed in gear-box respectively, on control frequency variator and the generator, and by the cooling medium intake pipe, cooling medium return pipe and recycle pump and cooling medium heat exchanger are connected to form circulating cooling system, it is characterized in that: above-mentioned circulating cooling system also comprises the evaporation circulating cooling machine that is arranged on outside the lid of cabin, and it links to each other with the cooling medium heat exchanger by pipeline.
The cold of this evaporation circulating cooling machine manufacturing passes to cooling medium in the cooling line by the cooling medium heat exchanger, again by the cooling medium circular flow through generator heat exchanger, gear-box heat exchanger and control frequency variator heat exchanger, the heat that their produce is taken away.
Compare with forced air cooling, the water-cooled wind-driven generator of present employing, have outstanding advantages such as refrigerating capacity is big, regulating power strong, good stability, can satisfy high-power cooling requirement, lay the foundation for developing high-power wind-driven generator group of new generation.In addition, because refrigerator can provide lower chilling temperature, can provide wind-driven generator required optimum working temperature, thereby significantly improve wind-power electricity generation efficient.
