摘要近年来,悬浮颗粒物（灰霾、雾霾）的存在对高压直流输电线路电磁环境的影响已成为了新兴的研究重点,而目前,悬浮颗粒物对直流导线电晕特性的作用机理仍不清晰。该文使用燃香颗粒模拟灰霾天气,利用同轴圆柱电极进行了直流导线电晕特性的实验研究,并结合测试计算结果,对悬浮颗粒物影响直流导线电晕特性的作用机理进行了分析解释。得出如下结论：随着悬浮颗粒物的增多,电晕放电程度增强,离子粘附在悬浮颗粒物上导致有效迁移率减小,致使测得的电流密度减小;悬浮于空中的空间总电荷密度增加,致使测得的合成电场强度增大。

Abstract：In recent years, the impacts of suspended aerosols (haze and fog) on electromagnetic environment of HVDC transmission lines have become an emerging research issue. At present, the mechanism of suspended aerosols on corona characteristics of HVDC conductors is still unclear. In this paper, the effect of aerosols on the ionized field of the current wire was studied using the coaxial cylindrical electrode and burning incense aerosols to simulate haze atmospheric condition. The influence of aerosols of different mass concentrations on the ionized field of HVDC conductors was investigated. The mechanism of suspended aerosols affecting corona characteristics of DC conductors was analyzed and explained in combination with the calculation of test results. It is concluded that, with the increase of suspended aerosols, the degree of corona discharge increases, ions adhesion on suspended aerosols results in a decrease in equivalent mobility and a decrease in measured current density. The increase of total space charge density suspended in the air causes the increase of the measured electric field strength.

Key words： HVDC aerosol corona characteristics mechanism research
