摘　　要：采用水冷却方式的发电机定子绕组,水电接头把合密封不严、焊接质量不好、空心铜线有裂纹或砂眼、振动、腐蚀等原因都可能造成线棒漏水。介绍了一起300 MW水内冷汽轮发电机定子绕组漏水事故的分析和处理过程,可对同类事故的处理提供借鉴。If the generator stator winding is cooled by water,water leakage may occur due to poor sealing of the water and electricity joints,poor welding quality,cracks or sand holes in the hollow copper wire,vibration,corrosion,and other reasons.The analysis and treatment process of stator winding leakage accident of a 300 MW water-cooled turbine generator is introduced,which can provide reference for the treatment of similar accidents.
