| 摘 要： | 随着特高压交直流输电工程的进行，高海拔电晕问题越来越受到关注。在可以调节气压和湿度的有机玻璃罐中，利用棒一板电极，对交流电晕特性随气压、湿度的变化规律进行试验研究。结果表明：交流电晕起始电压均随着气压降低、湿度升高而减小；交流电晕脉冲平均幅值均随湿度升高而减小；正半周流注脉冲平均幅值随气压降低而减小，而负半周流注脉冲平均幅值随气压减少而增大；交流电晕脉冲频率均随湿度升高而增大；随着气压降低，正半周流注脉冲个数没有明显的变化趋势，而负半周流注脉冲频率随气压降低而增大。

| Abstract: | Corona problem at high altitude has attracted more and more attention from investigators as UHV AC and DC transmission lines is being constructed.In the chamber made of organic glass for adjusting pressure and humidity,it was studied that the variation of ac corona characteristics with air pressure and humidity through rod plane electrodes.It was found through experiments that the inception voltage of AC corona was reduced as pressure decreased or humidity increased.Furthermore,the average amplitude of AC c... |
