摘　　要：华能岳阳电厂一期2台362.5MW机组投产以来,存在内冷水pH值低,定子线棒内壁腐蚀严重和堵塞等问题。通过摸索总结,目前采用离子交换微碱化技术,调节内冷水呈微碱性,从而有效地抑制了铜导线的腐蚀,水质优于国家标准值。Since 2×362.5MW units imported from UK in Huaneng Yueyang Power Plant put into operation, PH value of generator inner cooling water has been extra low and inner wall of stator bar has been badly eroded and blocked. In- ner generator cooling water is treated by ion exchange micro-basification and water turns to micro-basification, effec- tively controlling erode of copper coil. Water quality then exceeds GB standard and scheduled object is achieved.
