【摘要】:安谷水电站机组是超大型轴流转桨式水轮发电机组,定子机座散装运输到场,机座安装采用现场焊接方式。为克服机座尺寸大、质量重、当地温差大等定子安装精度的不利影响,介绍了定子机座焊接组装、定位筋安装调整、铁芯叠片和铁损试验等关键工序,并通过分析机组定子安装工艺和实践总结,优化了施工工序。实践证明定子组装质量得到严格控制,各项控制指标均满足规范标准,其安装工艺对同类型机组定子安装具有指导意义。
[Abstract]:Angu Hydropower Station unit is a super large shaft flow propeller type hydrogenerator unit, the stator seat is transported in bulk, and the installation of the base adopts the spot welding method. In order to overcome the adverse effects of large size, heavy weight and large local temperature difference on stator installation accuracy, the key processes such as stator seat welding assembly, positioning reinforcement installation and adjustment, iron core lamination and iron loss test are introduced. The construction procedure is optimized by analyzing the installation technology and practice of the stator. The practice proves that the quality of stator assembly is strictly controlled and all the control indexes meet the standard. The installation technology of stator assembly is of guiding significance for the stator installation of the same type of units.
