摘　　要：对水布垭电厂发电机定子绕组各种电晕故障进行了原因分析,并分别制定了解决方案。处理完成后,发电机各相绕组起晕电压均有明显提高,成功避免了电晕进一步发展进而破坏发电机线棒主绝缘的重大事故。Several corona faults found in the generator stator windings in Shuibuya Hydropower Station are analyzed . Corresponding treatment measures are then proposed and applied .It shows that the corona onset voltage values for all phase windings of the generator are increased obviously , which could prevent the further development of the corona faults and protect the main insulation of the generator winding bars .

关 键 词：发电机 电晕 绝缘 防晕处理
