十三陵蓄能电厂3号发电机定子绕组防晕检修处理

Anticorona Maintenance on Stator Winding of Unit 3 Generator of Shisanling Pumped Storage Power Station

发电机定子绕组防晕不仅是对发电机制造工艺的一项重要要求,也是运行检修重点监测的项目。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。对十三陵蓄能电厂3号机组定子绕组防晕层的故障作了分析,并采取了检修处理,其方法为电力行业类似问题的解决提供了一定的参考。

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 anticorona coating on stator winding of unit 3 in Shisanling Pumped Storage Power Station is analyzed. The anticorona measures are introduced which will provide certain reference and guidance for the tackling of similar problems in power sector.
