雾霾对接触网绝缘子电位和电场分布的影响
Effect of fog haze on potential and electric field distribution of composite insulator of catenary
摘要
Abstract
In order to study the effect of haze environment on the surface potential and electric field distribution of the insulator, a two-dimensional simulation model of the composite insulator was established based on the electrostatic field finite element method. The finite element software Comsol was used to analyze the potential and electric field distribution of the insulator with respect to different haze concentrations. The simulation results show that the suspended haze particles in the air will distort the surface potential and electric field of the insulator slightly when it is not charged. However, when the haze particles near the insulator are charged, they will exert significant influence on the corresponding potential and electric field distribution. The different concentration of the haze particles and the different charge polarity will have different effects on the surface potential and the amplitude of the electric field distortion.关键词
