摘要
鉴于三峡某型机组定子线棒在定子铁芯槽口位置出现电晕,从线棒防晕结构、定子下线使用的材料等方面分析了电晕产生的原因,并探索了消除电晕的方法,经过专项消缺处理,机组运行良好。
In some generator units in the Three Gorges Hydropower Station, corona phenomenon is observed in the loca- tion of the iron-core slots of the stator winding bars. Possible reasons of such corona are analyzed from aspects of the an- ti-corona structure for the winding bars and materials used in the stator installation. Measures to eliminate such corona are then proposed. Practice shows that the generator units operated well after the treatment.
