摘　　要：绝缘子自然积污特性研究对架空输电线路的外绝缘配置具有重要意义。为研究特高压直流输电线路积污特性,准确设计线路绝缘配置。笔者通过对±800 k V楚穗直流输电线路沿线绝缘子串进行人工污秽取样分析,结合线路沿线的气候特征及污染源,研究气象条件、污染源以及材质对外绝缘积污的影响。研究表明,特高压直流线路绝缘子积污受大气环境与污染源的影响;复合绝缘子表面污秽度远大于玻璃和陶瓷绝缘子。The natural pollution rule of insulator is very important for the external insulation determination of overheadtransmission line. To study the pollution rule of UHV DC transmission line, accurately design the line insulationconfiguration, based on the sample analysis for the artificial contamination of the insulator string along the line inChu-Sui ±800 kV DC transmission line, combined with the climate characteristics and pollution sources. The in-fluences of meteorological conditions, pollution sources and materials on external insulation pollution are studied.The research shows that the pollution of the insulator is influenced by the atmospheric environment and the pollu-tion sources. The surface contamination degree of composite insulators is much higher than that of glass and ceram-ic insulators.
