摘 要：为了研究雾霾天气下，颗粒在绝缘子表面上的积污规律，本文设计搭建了绝缘子人工雾霾试验平台，并且利用此平台对0~10 μm的细颗粒在不同风速下的沉积进行试验研究。研究结果表明：2.5~10μm范围内的颗粒浓度降低幅度最大；0.6~2.5μm范围内的颗粒浓度降低幅度次之；0~0.6μm范围内的颗粒浓度降低幅度很小，相对于前两者，可以忽略其沉积量；0~10μm的颗粒在低风速（v≤1.5 m/s）下的浓度降低比率近似相等，在高风速（v≥2.5 m/s）下的浓度降低比率也近似相等，二者遵循不同的积污规律。

Abstract:In this paper,in order to study the particle deposition characteristics on the surface of insulators in fog and haze weather,the artificial haze experiment platform was designed and constructed,and the deposition rate of fine particles of 0~10μm under different wind speed were tested and compared.The results showed that,in the range of 2.5~10μm,the particle deposition rate is the largest,followed by the particles in the range of 0.6~2.5μm.The particle deposition rate in the range of 0~0.6μm is very small,compared with the two aforementioned,and the deposition amount can be ignored.For the particles with 0~10μm diameter,the deposition rate is nearly the same under low wind speed (v≤1.5 m/s) or high wind speed (v≥2.5 m/s),while they follow different deposition trends.
