针对西北地区风沙侵蚀输电导线现象，研究了导线粗糙度与起晕电压关系，在闭式风道内模拟了输电导线在第一年服役内受强沙尘暴侵蚀过程，并做了侵蚀铝棒的对照实验。用光切显微镜测量了表面粗糙度，电晕笼测量系统测量了起晕电压，再对实验数据插值与拟合处理，分析认为，导线粗糙度随风沙侵蚀呈增大趋势，而起晕电压在试验前期升高，试验中期起伏变化，后期与粗糙度呈负相关关系，即导线起晕电压随着粗糙度增大而降低。

For the phenomenon of sand eroding transmission line in the Northwest, the relationship of wire roughness and corona inception voltage are studied, in the closed wind tunnel, the eroded process of transmission line by strong storm in the first year of service is simulated. And a control experiment of rod erosion was made also. The surface roughness is measured by light-section microscope, and the corona inception voltage is measured by corona cage. And then the experimental data is processed by interpolation and fitting method. It is concluded that the roughness tends in-crease with erosion. But corona inception voltage rises at the prophase and is up and down at the interim, and corre-lates with the roughness negatively in the latter,that corona inception voltage decreases with roughness.
