汽轮发电机汇水管典型故障分析及对策

Analysis and Strategy for Typical Faults of the Water Manifold in the Turbine Generator

介绍了汽轮发电机汇水管的结构及功能,对近年来出现的发电机汇水管相关的典型电气及非电气故障进行了分析探讨。针对汇水管金属性接地故障,介绍了利用全绝缘暂态高压脉冲信号发生器靶向击穿接地点的应用案例,并对发电机汇水管的运行维护提出了合理化建议,为应对发电机汇水管故障提供了借鉴。

The structure and function of the water manifold in the turbine generator is introduced.A series of electrical and non-electrical faults are analyzed and discussed.For a typical metallic grounding fault of the water manifold,the paper introduces the application case of target breakdown contact by using full insulation transient high-voltage pulse signal generator.Several reasonable suggestions are put forward for the operation and maintenance of the water manifold as a reference.
