20kV级水氢冷汽轮发电机定子绕组防晕设计的优化

摘要

本文以宁海电厂600MW发电机定子绕组端部烧蚀问题的原因分析及处理措施为例,从技术标准及定子绕组防晕设计原理出发,阐述了20kV级水氢冷发电机定子绕组槽部、端部防晕的设计优化.%By cause analysis and disposal methods for the stator winding failure of 600MW at Ninghai power plant,this paper explained the corona specification standard of generators,introduced the optimization of the anti-corona design in the stator winding of 20kV water-hydrogen cooled turbo-generator.
