600MW汽轮发电机定子绕组水电接头泄漏分析

Analysis on termination leakage of stator winding of 600 MW turbo-generator

某电厂一台600MW机组在常规大修中,发现定子绕组多处水电接头漏水,检查发现水盒和空心导线等处泄漏,采取现场修理的办法,成功消除了漏水缺陷。本文详细介绍漏水处理的经过。

During the regular major repair of a 600 MW set, water leakage was found in water electricity terminations of the stator winding. Leaks in the water cage and hollow core leads are examined and repaired and leaks no longer exist. The treatment process is introduced in the paper.
