【摘要】 针对秦山三核2号发电机在高负荷工况下出现突发性振动上升问题进行测试分析,认为突发性上升振动问题的原因是发电机转子线圈在热态下膨胀受阻引起发电机转子热不平衡而导致的。提出了机组继续运行所需要采取的措施。采取措施处理后彻底解决了机组的振动问题。更多还原

【Abstract】 The paper measured and analyzed the problems of sudden strong vibration of No.2 generator in Third Qinshan Nuclear Power Co.,Ltd in the condition of lager load,it is believed that why the vibration’s sudden go-up is the unbalance heat of generator rotor coil caused by expanding of generator rotor coil restricted at thermal condi-tion,thus some measures were proposed to solve them,the actual operation case showed that they are effective.更多还原
