摘　　要：介绍了发电机定子绕组手包绝缘施加直流电压测量方法,阐述了正接线和反接线试验方式的试验方法和实验原理,分析对比了两种接线方式的优缺点,针对传统的试验接线方式中存在的问题提出了改进措施,给出了一种新的基于传统反接线方式的手包绝缘测试方法,既能满足在定子通水状态下进行试验,又极大地缩小了试验设备容量,工程运用表现良好。Introduction was made to the method of direct current voltage measuring imposing on the hand-making insulation of generator stator winding.This paper expounded the test method and experimental principle of positive and reverse connection test modes,and analyzed and compared two kinds of relative merits of two types of connection modes.Aiming at the problems existing in traditional test connection mode,this paper proposed the improved measures and gave a new kind of hand-making insulation test method,which not only met the requirements of the test under conditions of stator through-water state,but also greatly reduced the test facility capacity,with good engineering application.
