Novel steam turbine generator stator frame structure

Abstract

The invention discloses a novel steam turbine generator stator frame structure which comprises a bottom frame; a machine box which comprises a lower base and an upper base, wherein the lower base is welded and fixed to the upper end face of the bottom frame, a first flange is arranged on the outer edge of the upper end of the lower base, the upper base is arranged above the lower base, and a second flange connected with the first flange in a matched mode is arranged on the outer edge of the lower end of the upper base; and a cooling cover which is fixed to the upper end face of the upper base in a buckled mode, wherein an air cooler is installed in the cooling cover; the case for mounting the stator is split into the upper base and the lower base which are oppositely arranged up and down, so that a production line for producing the case is split into two parallel production lines for producing the upper base and the lower base, the production period is shortened, and when the stator iron core gasket is mounted, the lower base is horizontally placed and does not need to be erected, and the assembling process is more convenient.

Description

technical field [0001] The invention relates to the technical field of generator manufacturing, in particular to a novel turbogenerator stator frame structure. Background technique [0002] The stator frame is an important part of the turbogenerator unit, which plays the role of fixing, supporting and protecting the stator core in the turbogenerator, and also constitutes the overall ventilation circulation circuit of the generator inside. On this basis, the stator base also includes structures for fixing, cooling, lifting to meet the needs of normal use and transportation, and route layout. [0003] The traditional generator stator base and stator core are connected as a whole through positioning ribs, and the processing and installation cannot be carried out separately, and the production cycle is long. Moreover, the stator base and the chassis are two independent parts, and the ventilation interval is small, which is not conducive to the ventilation and heat dissipation o...
