抽水蓄能机组发电电动机磁极线圈位移的分析与监造

Analysis and Supervision Pole Coil Displacement of Pump-Storage Units

抽水蓄能机组磁极是一种在高转速状态下的磁极悬挂结构,其磁级线圈承受着巨大的离心机械应力、热负荷应力和电磁负荷应力,时刻存在着出现磁极线圈位移的可能,为此,就抽水蓄能发电电动机磁极线圈运行中出现过的位移故障进行分析并用来指导在建机组监造,很有意义。

Pumped storage generator pole is a high speed of magnetic suspension structure,magnetic coil under tremendous centrifugal mechanical stress,heat load stress and electromagnetic load stress,time appear pole coil displacement may exist,therefore,pumped storage power generation motor fault occurred in the operation of the pole coil displacement is analyzed and used to guide the existing units under construction supervision,very meaningful.
