天荒坪抽水蓄能电站发电电动机定子r绕组端部磨损松动处理

摘要

针对天荒坪抽水蓄能电站发电电动机定子绕组端部磨损松动的问题,经现场对绕组端部固有频率测量、数据分析及规律查找,结合设备结构提出了定子绕组端部固定的优化方案.实践表明处理方案可行、效果明显,可为抽水蓄能电站发电电动机定子绕组的设备计、安装及运维提供参考.%To deal with the problem of the Tianhuangping Power Plant generator mortor stator end winding wear and loose, through the field of end winding natural frequency measurement and data analysis, pattern search, combined with the equipment structure reinforcement and optimization. The practice result shows that the treatment scheme is feasible and effective. It can provide reference for the design installation and operation of the generator motor stator winding pumped storage station.
