潘口水电站定子结构特点及铁芯装配工艺研究

Study of characteristics of stator structure and assembling technique of core of Pankou Hydropower Station

潘口水电站水轮发电机组的定子采用了新颖的结构,即将临时方钢导向键作为定位筋,并采用了特型的拉紧螺杆,这些新型结构的运用,使定子铁芯的装配施工流程和施工方法得到了优化。简要介绍了潘口水电站水轮发电机组定子结构的特点,简述了定子铁芯的装配工艺,可为其他电站水轮发电机组定子结构设计及铁芯装配提供指导和借鉴。

The structure of stator of hydro - turbine of Pankou Hydropower Station is new, in which, the feather key of tempo- rary square steel is adopted as position bar and the particular rigging screw is adopted as well. The assembling process and con- struction method of core are optimized by the application of these new structures. The characteristics of stator structure of hydro - turbine of Pankou Hydropower Station is introduced in brief, so is the assembling technique of stator core, which provides refer- ence for design of stator structure and assembling, of core of hydro - turbines.
