浅析水轮发电机定子铁芯锈蚀及处理
|
摘要
本文以水轮发电机定子铁芯产生锈蚀的原因分析为契机,来进一步分析水轮发电机定子铁芯各种故障发生的原因及其产生的危害。本文的主要内容有:定子有效铁芯压装的变松、电阻温度计损坏引起有效铁芯的故障、定子绕组相间短路引起定子铁芯的损坏、铁芯片间绝缘的损坏引起定子铁芯故障,通过技术分析与实际检查相结合,确定了定子铁芯产生锈蚀的原因,并提出检修方法。
This paper takes the cause analysis of corrosion of hydraulic turbine generator stator core as an opportunity to further analyze the causes of various faults of turbine generator stator core and the harm caused by it.The main contents of this paper are:the loosening of effective laminated core,resistance thermometer damage caused by fault,stator winding short effective core damage caused by iron chip,the stator core insulation damage caused by stator core failure,through technical analysis and practical inspection combined corrosion causes of stator core is determined,and the maintenance method.
