污秽颗粒在绝缘表面的碰撞和吸附
Collision and Adsorption of Pollution Particles on the Surface of Electrical Insulator
摘要
Abstract
To investigate the factors affecting the adsorption of pollution particles on the surface of electrical insulator,we set up models of pollution particles and the surface of an electrical insulator,respectively.On condition that the surface boundary layer effect of electrical insulator is considered,the force on pollution particles and their movement during their collision and adsorption on the electrical insulator surface were analyzed,thereby a criterion for the absorption was formulated.The effects of the diameter of pollution particles,the mainstream wind speed in the air and the relative air humidity on the adsorption were also investigated.It is concluded that,among the factors affecting the adsorption,the diameter of pollution particles is the predominate factor,and the smaller the diameter is,the easier the adsorption is.The second influential factor is the relative air humidity,and the higher humidity is,the easier the adsorption is.The least influential factor is the mainstream wind speed in the air,and the faster the speed is,the easier the adsorption is.关键词
