摘　　要：转子是水轮发电机组的核心部件,其安装质量直接关系机组的安全稳定运行。随着水轮发电机组的设计、制造趋于大型化,转子现场安装难度越来越大。主要简述了溪洛渡左岸770MW巨型水轮发电机组转子安装关键技术。同时分析了巨型机组转子的结构特点,对转子磁轭叠装工艺过程做了深入分析、总结,对主力筋焊接提出了具体工艺方案,以及磁轭热加垫的工艺及转子圆度的调整方案。溪洛渡机组转子圆度及波浪度等各项参数均达到了溪洛渡安装标准,为百万机组的转子安装积累了一定经验及借鉴。The rotor is the core component of hydrogenerator unit, which installation directly relates the safe and stable operation of the units. As the developments of design and manufacturing, the size of hydrogenerator tends to be large, and the on-site installation of rotor becomes more difficult. This paper chiefly introduces rotor installation technology of 770MW supersized hydrogenerator unit on left bank of Xiluodu and analyzes its structural characteristic. The stacking process of rotor rim was deeply analyzed and summarized, the specific process scheme of welding main reinforcements was put forward, and the technology of adding shims by heated rim and scheme of adjusting rotor roundness were described in detail. All parameters such as rotor roundness and waviness of hydrogenerator unit have achieved installation standards of Xiluodu power station. It can provide some experience and reference for the rotor installation of million unit.
