摘　　要：对不带电绝缘子的自然积污特性与雾霾主要成分间的关系展开研究。首先比较了一年周期内不带电绝缘子的表面污秽度和同期SO2、NO2、PM2.5、PM10浓度间的变化规律,说明了污秽度与各成分浓度间的正相关性。发现SO2、NO2和PM2.5、PM10中的水溶性成分是可溶污秽物的重要来源,PM2.5、PM10中不溶于水的成分是不溶污秽物的重要来源。通过灰关联算法围绕雾霾成分对积污影响的研究发现,在雾霾各成分中,SO2对可溶污秽物的影响程度相对较大,PM10对不溶污秽物的影响程度相对较大;大气中PM2.5、PM10、NO2和SO2浓度上升时,更易加剧绝缘子表面可溶污秽物的生成。The relationship between the natural contamination characteristics of the insulators and the ingredient of fog-haze（PM2.5、PM10、SO2、NO2） are researched. According to the curves of the surface pollution degree of insulators and the curves of the fog-haze components concentration, the positive correlation between the pollution degree and the fog-haze components concentration is represented. It is found that SO2, NO2 and PM2.5, PM10 are important sources of soluble pollutants on the surface of insulators, while the insoluble components of PM2.5 and PM10 are important sources of insoluble pollutants. The research on effect of fog-haze components on contamination by the grey correlation analysis shows that, among the fog-haze components, the pollution effect of SO2 on soluble pollutants is greater; the pollution effect of PM10 on insoluble pollutants is greater; with the increase of the concentrations of PM2.5, PM10, SO2 and NO2in the air, the content of soluble pollutant rises more seriously.
