Background
The stator core of the water turbine generator set is a key component of the generator, and the reliability of the stator core is an important guarantee for long-term safe and stable operation of the water turbine generator. The damage of the stator core can be divided into mechanical damage and fusing damage according to damage forms, wherein the mechanical damage comprises the fracture of a punching sheet, the scraping of the surface and the impact of the surface; the fusing damage can be divided into surface fusing, tooth fusing and yoke fusing. The stator core is mostly caused by bar grounding or interphase short circuit, and the fusing damage degree of the stator core is different due to different current magnitude in the machine set bar and bar grounding reasons. In addition, stator iron core pieces are communicated, and the core penetrating screw rod is grounded and the like, so that the stator iron core is locally overheated, and finally, the stator iron core is fused. The fused zone in the middle of the core is usually repaired by re-lamination.
If the generator is swept out of the chamber or the stator bar is in short circuit fault in a flood season, serious damage can be caused to the stator iron core. If the stator core needs to be replaced by the lamination again, the time is about 200 days, and the social influence and the economic loss are huge.
