摘　　要：本文介绍了ALSTOM集团的水轮发电机的结构设计和安装特点。定子机座采用斜立筋结构 ,转子支架、上机架、下机架采用斜支臂结构。此结构不影响机组的轴向刚度 ,但增大了径向柔度。推力轴承采用自身泵外循环冷却系统。通过薄瓦和托瓦之间小钢柱在瓦面上分布位置差异及小钢柱直径差异来保证推力轴承安全稳定运行。This paper introduces the features of structural design and installation of the hydrogenerators produced by ALSTOM group. Stator frame uses skew rib.Rotor spider, upper and lower brackets use skew arm. This structure has no influence to the unit axial stiffness, but increases the radial flexility. Thrust bearing adopts self pump outer circulation cooling system. Bearing safe operation is ensured by different location of little steel pillars between the thin segment and supporting segment, and the different diameters of the steel pillars.
