为深入分析雾霾对外绝缘特性的影响机理，调研了国内外关于雾霾对输变电设备外绝缘特性的相关研究。从雾霾的形成与沉降、雾霾的模拟、其对输变电外绝缘特性的影响几个方面进行探讨。结果表明：雾霾主要是由人类活动产生大量的污染物质在一定相对湿度的气象条件下形成的，雾霾天气下绝缘子放电主要以沿面闪络为主，雾霾沉积在绝缘子表面或漂浮在绝缘子片间空气间隙中会降低绝缘子的污闪电压。建议在绝缘子分布密集的雾霾天频繁区域加强环保工作，采取有效措施防止雾霾对输变电设备外绝缘特性的影响，保证绝缘子安全、可靠、稳定的运行。

To research the effect of haze on external insulation performance in depth, this paper investigates the related results at home and abroad. The formation and sedimentation of haze, the simulation and its influence on power transmission devices external insulation performance are discussed and analyzed. The results show that haze is formed by human activities that produce a large sum of pollutants in a certain wet weather condition, the main discharge sort of insulator is surface flashover, the pollution flashover voltage is well decreased if haze sets onto the insulator surface or floats into the air gap between insulators. So in the area where haze appears frequently and insulators distribute dense, green jobs should be reinforced, and effective measures should be taken to prevent the influence of haze on power transmission devices external insulation performance to ensure insulators run safely, reliably and stably.
