摘　　要：近年来,雾霾作为一种特殊的天气,受到了人们的普遍关注。本文在临时搭建的雾霾实验室中,采用中值直径为2.5μm的高岭土颗粒和硫酸铵溶液模拟了不同浓度的雾霾,并进行了电晕损失特性试验,所得到的雾霾颗粒直径、雾霾浓度与真实雾霾差异不大。不同雾霾浓度下的电晕损失特性试验表明:随电场强度的增大,雾霾条件下输电线路的电晕损失不断增大,并符合幂函数的增长趋势;随输电线路导线周围雾霾浓度的增大,其相应的电晕损失也增大,但增加量不明显。As a special weather condition,fog-haze has widely public attention.A temporary fog-haze chamber is built in this paper,kaolin particle with medium diameter of 2.5μm and(NH4)2SO4 resolutions are adopted to simulate the fog-haze.The corona loss experiments are performed in different fog-haze densities.The obtained artificial simulated particle diameter and fog-haze density are similar to that of real fog-haze.The corona loss experiments in different fog-haze densities show that:The corona loss grows in a shape of power function with the increase of electric field intensity.Moreover,with the augment of fog-haze density around the transmission lines,the corresponding corona loss also increase,but the increment is not significant.
