Title:
STATOR IRON CORE MELTING REPAIRING DEVICE AND METHOD FOR LARGE HYDRO-GENERATOR
Document Type and Number:
WIPO Patent Application WO/2022/179464
Kind Code:
A1
Abstract:
A stator iron core melting repairing device and method for large hydro-generator, the device comprising toothed plates, ventilation slots, binding holes, ventilation holes, and binding cables. The toothed plates are fitted with a melting area at the middle part of an iron core, two ends of the toothed plates abut against lamination groups, and the binding cables pass through the binding holes and tighten for binding, such that the toothed plates and bars are bound into an integral structure. The present invention overcomes the problem that the power generation benefit during a flood season is affected by a long lamination cycle after the middle part of a stator iron core of a hydro-generator melts, and has the characteristics of simple structure, capability to repair the melting area in the middle part of the iron core without needing to re-laminate, fast repair speed, high repair efficiency, short repair cycle, and simple and convenient operations.
