制造厂为了保证航空发电机的质量可靠,每季度或每半年必须从生产的产品中抽两台电机进行型式试验或称例行试验。由于发电机功率较大,因此试验耗电量很多,尤其做使用期试验,时间很长,所耗的电能就很可观了。长期以来,发电机发出的电能没有被利用,而是以热能的形式散发到空间,增加试验环境的温 In order to ensure the reliable quality of the aerogenerator, the manufacturer must pull out two motors from the produced products on a quarterly or semi-annual basis for type testing or routine testing. As the generator power is large, so a lot of power consumption test, especially to do the test period, a long time, the power consumption is very impressive. For a long time, the power generated by the generator has not been utilized, but emitted in the form of heat to increase the temperature of the test environment
