| Abstract: | 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. |
