Wind generators in the current industry, domestic wind round, made in China reached 283,500 basic degree, and generators were developed, and now exciter generators and electrical boxes also can not meet the market demand standards. Abroad as a generator exciter style is the need to match growth gear boxes, problems with three aspects : 1, a torque are relatively large, 2, oil spills, 3, gear worn serious, gear boxes in the MW class wind generators Group overload and higher rates of premature damage to the components.
Domestic commonly used straight-Type units (directly driven by wind generators round), although currently developed to 50KW, but in fact there are serious technical problems : a torque are relatively large, electrical fever, weight size large, life short, conversion efficiency (less than 50%). As generators actual output is too low, resulting in blind enlarged electrical size, which in turn increase the production costs. These problems constraining the development of wind energy.
In response to these issues, we conducted years of experimental research company, recently developed a new technology programme, a complete solution to the problem. Direct-to 20KW generators, for example, we are using new technologies to make prototype, the truth is as follows ideal results : a torque of less than 14N m, rated rotational speed 150r/min, rated output power 20KW, 25KW largest exporting power, and load 20KW operation two hours later, the surface temperature less than 50 degrees Celsius. environmental temperature of 18 degrees Celsius, the heat release has not taken any measures to cool down naturally. New technologies can be applied in the same 5KW above all wind generators. As can be seen from the above data, the introduction of new technology for 100% wind power generators export and organisms as relatively low temperature, torque is relatively small, relatively useful life also greatly increased. And because this is a traditional gear box parts, the introduction of new technology more wind generators with a low noise, long life, small size units, the operation of low-cost manufacturing, low wind speed, high efficiency and other advantages. As new technologies have been settled principles, MW-class straight-type low-speed permanent magnetism generators manufacturing has not technological obstacles.
The company's current main products : wind generators : 100W, 200W, 300W, 500W, 1Kw, 2Kw, 5Kw, 7.5 kw and 10 kw, 20 kw and 50 kw;
