高海拔下汽轮发电机定子绕组端部的防晕

Corona Protection of the Stator Winding End of Turbine Generator Under High Height Above Sea Level

讨论了高海拔下汽轮发电机定子绕组端部防晕技术要求,并籍此分析了660 MW双水内冷发电机的防晕结构,认为该机定子绕组防晕结构设计能满足海拔4 000 m试验和运行要求。

Technical requirement for corona protec- tion of the stator winding end of turbine generator under high height above sea level was discussed while the corona protection construction of the 660 MW double-water in- ner-cooled turbine generator was analyzed, verifying this design of corona protection construction of the generator stator to meet with the experimental and operational re- quirements at height 4 000 m above sea level.
