摘要
根据刘家峡3号水轮发电机定子存在的问题及隐患,阐述了改造前、后发电机的主要参数及设计结构。本次改造解决了机组定子原来存在的定子接地、绝缘击穿等问题,提高机组安全运行稳定性,为后续电站改造提供了参考。
Based on the existing problems and hidden dangers about the stator for Liujiaxia third hydro-generator,this paper explains the main parameters and design structure of the generator before and after the renovation.The renovation has solved the original problems of the unit stator,improved the safe operation and stability of the unit,and then provided a reference for subsequent power station renovations.
