摘　　要：通过对国产防晕材料的选择及开发 ,对不同的电阻率及非线性系数的防晕带进行优化设计和搭配 ,确定了适用于 2 0 k V级及以上大型高压水轮发电机定子线棒的防晕材料和防晕结构 ,研究的成果应用到三峡发电机真机线棒上达到 ABB- AL STOM的技术要求。Through the selection and development for the internal corona protection materials ,the corona protection tapes with different resistivity and nonlinear coefficient have been optimized and matched reasonably in this subject .These kinds of materials and structure adapt to more than 20kV high voltage hydro generator and have applied on the three gorge project units and met the requirements of the ABB Alstom.
