The electric breakdown of a stator winding insulation at thermal state and reducing of the electric properties of epoxy-mica paper insulation, often occurred in the preventive test of two TS1260/200-48,225MW,15.75kV hydrogenerators for a certain water power station, have been studied.In this paper, some views on the test voltage values of the resistance voltage test and a critical value on the reducing of the electric properties are presented.

本文就某水电厂TS1260/200-48型、225MW、15.75kV发电机(1、2号机)定子绝缘在预防性试验中常出现热态耐压击穿现象和环氧粉云母绝缘电性能下降的临界值进行了研究。针对耐压试验值和性能下降的临界值问题提出了看法。

It is proved that the epoxy-mica paper insulation produce by HEC behaves excellently in long-term operations. Methods to . diagnose and estimate the remaining life of the epoxy-mica paper insulation on HV hydrogenerators are produced from large number of test data. The use of D- map method to this insulation is also discussed. This article offers criteria to replace in time the bad coils.
