摘要
运用溢出电位法准确地判明定子端头盒绝缘缺陷,找出水轮发电机定、转子绕组绝缘击穿和下降的原因,并提出了有效的处理方法。
The defects of end-node insulating boxes of the hydrogenerator stator of Baishan Hydropower Plant are ascertained accurately by means of spillover electric potential, the causes why the winding insulating of hydrogenerator stator and rotor is breaked and droped are found out, and the effective treatment measures are proposed.
