龙开口水电站定子组装施工工艺

Stator Assembly of Generator in Longkaikou Hydropower Station

对龙开口水电站发电机定子组装施工过程中的机座组装焊接、定位筋安装以及铁心叠片进行了详细介绍,其中在定位筋安装时采用的"片—筋—片安装法"先由预叠片定位、调整,安装焊接后再叠装铁心冲片,与传统工艺相比,具有定位筋分度、弦长与垂直度易于控制的优点,由于先焊接后叠片,也不存在施工干扰。工艺简单、技术先进,值得在同类型的定子组装过程中进行推广。

The frame welding, positioning bar installation and core laminating of generator＇s stator in Longkaikou Hydropower Station is introduced herein. The Sheet-Bar-Sheet Installation Method is adopted in the installation of positioning bars, in which, the positioning bars are firstly positioned and adjusted by pre-laminated core and then welded. The core is followed to laminate after positioning bar welding. This Method has the advantages of easy to control the indexing, chord and verticality of positioning bar, and because of core laminating after welding, there is no disturbance in stator assembly. The Method is simple in process and advanced in technology.
