摘要

为研究高海拔对特高压直流输电线路电晕性能的影响，在小型电晕笼中测量了101 ~ 61 kPa不同气压水平下铜线的电晕起始电压梯度。将计算结果与Peek定律的计算结果进行了比较，并给出了气压的起晕电压梯度校正系数。

Study of UHV DC corona performance in a mini corona cage

To research the effect of high altitude on corona performance of UHV DC transmission line, the corona inception voltage gradient of a copper line at different air pressure level from 101 kPa to 61 kPa was measured in a mini corona cage. The results have been compared with calculated results of Peek law and the corona inception voltage gradient correction factor of air pressure was presented.
