在发电机主、副绕组发生短路并要查找时,一般可用耐压试验进行检查。这在制造厂家是极易办到的,但在运行中的发电厂特别是广大农村小水电站中,因条件等原因的限制则不易做到。最近,我们对一台 TSW—59/41—6 160千瓦同步发电机利用一只兆欧表和万用表查出了主、副绕组的短路点,仅用一天时间恢复了发电生产,收到了良好效果,现将具体作法介绍如下:
In the main generator, the secondary winding short circuit and to find, the general available pressure test to be tested. This is extremely easy for manufacturers to do, but in the operation of power plants, especially the vast rural small hydropower station, due to conditions and other reasons is not easy to do. Recently, we used a megohmmeter and a multimeter to detect the short circuit point between the main and secondary windings of a TSW-59 / 41-6 160-kilowatt synchronous generator. The power generation was resumed in only one day and received good results , Now the specific practices are as follows:
