摘要
介绍了三峡电站水轮发电机组四部轴承的具体布置及轴电流的产生原因和危害,结合实际测量数据,说明了轴CT测量方式的缺陷,通过对三峡机组大轴结构、轴电势分布状况的分析,提出了大轴绝缘监视的新方案,并对该方案具体实施及工程应用存在的问题给出了全面的解决方法。
Concrete arrangement of the four bearings of the Three Gorges Power Plant water-turbine generator set and the reason producing shaft current and its harm are introduced.By combining the actual measurement data,the axis CT survey way flaw is showed.A comprehensive solution to concrete implementation of the proposed new plan and the existing problems in the engineering application are presented.
