摘　　要：文章以某电厂660 MW水内冷发电机定子线棒化学清洗为例,采用NLF-010固体无机酸加缓蚀剂为清洗介质、氢氧化钠活化和MBT预膜工艺。采用此清洗工艺对发电机内冷水系统进行化学清洗后,定子线棒铜导线内壁沉积物和腐蚀产物去除明显,提高了定子线棒换热效率,降低了定子线棒温度,有利于发电机的安全稳定运行。In this paper,the chemical cleaning of stator wire rod of a 660 MW water-cooled generator in a power plant is taken as an example.NLF-010 solid inorganic acid plus corrosion inhibitor is used as cleaning medium,sodium hydroxide activation and MBT pre-film process are adopted.The internal cold water system of the generator is chemically cleaned by this cleaning process.The inner wall deposits and corrosion products of the copper conductor of the stator wire rod are removed obviously,the heat transfer efficiency of the stator wire rod is improved,the temperature of the stator wire rod is reduced,and the safe and stable operation of the generator is facilitated.
