3号发电机定子绕组防晕检修处理

Anticorona Treatment on Stator Winding of Unit 3 Generator

发电机定子绕组防晕不仅是发电机制造工艺的一项重要要求,也是运行检修的重点监测项目,在绕组端部区域,由于电场强度相对较大且极不均匀,最容易发生电晕,因此就十三陵蓄能电厂3号机组定子绕组防晕层故障作了分析,并介绍了检修处理的方法,为电力同行解决类似问题提供了一定的参考和指导作用。

Corona proof of stator winding is not only a necessary requirement in generator manufacturing ,but also a key monitoring item in operation and maintenance. Corona is easily happened on the winding end where electric field is relatively high and unbalanced. The failure of anticorona coating on stator winding of unit 3 in Shisanling Pumped Storage Power Plant is analyzed. The anticorona measures are introduced which will provide certain reference and guidance for the tackling of similar problems in power sector.
