Abstract

The invention discloses a stator iron core structure of a hydrogenerator and a molding method thereof. The stator iron core structure comprises a plurality of silicon steel sheets; according to the arrangement position of the silicon steel sheets on a stator base, the silicon steel sheets are divided into a middle iron core assembly and end iron core assemblies at the two axial ends; each siliconsteel sheet of the end iron core assembly is bonded and assembled into an integral annular structure according to the arrangement order, the silicon steel sheets of the middle iron core assembly are stacked and arranged between the end iron core assemblies of the integral annular structure at both ends in the arrangement order, and the end core assemblies at both ends respectively bear the axial locking force of the stator core pressing mechanism to the stator core structure in the axial direction. The present invention not only does not obviously increase the technical difficulty of processing and assembling the stator iron core structure, but also can meet the technical requirements of the service condition, and can effectively solve the technical problem that the axial locking force ofthe stator iron core structure on the stator frame is liable to be destroyed, which is favorable for the long-term safe and stable operation of the hydrogenerator.

Description

technical field

[0001] The invention relates to a hydraulic generator, in particular to a new stator core structure of a hydraulic generator and a forming method of the stator core structure. Background technique

[0002] The stator of the hydro-generator is the static part of the hydro-generator. It is mainly composed of the stator frame and the iron core and windings assembled on the stator frame. And the necessary electromagnetic part of the current path.

[0003] The stator core structure of a hydroelectric generator is composed of a number of silicon steel sheets stacked on the stator frame according to the set arrangement sequence, especially the stator core structure of a large-scale hydroelectric generator. , each layer of silicon steel sheets is composed of several fan-shaped silicon steel sheets in a circumferential butt joint manner according to the set arrangement sequence. The stator core structure stacked and formed on the stator frame is fixed by the axial l...
