通过涂污的 XP-70型绝缘子在盐雾条件下的人工污秽试验，研究在粉尘污染源较少且靠近海的地区海盐污秽单独对表面洁净绝缘子闪络特性的影响，以及在粉尘污染源较多且靠近海的地区粉尘污秽和海盐污秽共同对绝缘子闪络特性的影响。试验结果表明：盐雾电导率越大，绝缘子的闪络电压越低；绝缘子表面等值附盐密度越大，其闪络电压越低。针对沿海地区环境情况，对海盐污染地区绝缘子选型提出建议：粉尘污源较少地区选用钟罩型玻璃绝缘子；粉尘污源较多地区选用复合绝缘子，但应综合考虑其老化特性。

By artificial pollution test on polluted XP-70 insulator under salt fog condition,this paper studies affect on flash-over characteristic of insulator with clean surface only by sea-salt pollution in the area close to the sea with less dust pollution source. Meanwhile,it studies affect on flashover characteristic of the insulator by dust pollution and sea-salt pollution collec-tively in the area near to the sea with more dust pollution source. Experimental results indicate that conductivity of salt fog is larger,flashover voltage of the insulator is lower and equivalent salt deposit density on the surface of insulator is larger , the flashover voltage is lower. Based on environment of the coastal areas,model selections for insulators in sea-salt polluted areas are proposed which is to choose bell jar typed glass insulators for the areas with less dust pollution source while compos-ite insulators for those areas with more dust pollution source but comprehensively considering the aging characteristics.
