摘　　要：首先,引入绝缘子沿面放电的物理现象,介绍了电晕与闪络两种沿面放电现象。其次,研究了架空线路中悬式绝缘子的电位分布以及片数选择问题。讨论了沿面放电的外部影响因素、内部机理以及产生闪络的原因。同时,举例分析了绝缘子在不同电场分布情况下,在污损情况下的沿面放电特性。最后,基于全文的分析提出了消除悬式绝缘子沿面放电的可行方案。First,this article introduces the physical phenomenon of the surface discharge of insulators,and intro-duces two phenomena of surface discharge:corona and flashover.Then,it studies the potential distribution of sus-pension insulators and the selection of their number in overhead lines,discusses the external influencing factors and internal mechanisms of surface discharge and the causes of its flashover,and gives examples to analyze the characteris-tics of the surface discharge of insulators under the condition of different electric field distribution and fouling.Fi-nally,based on the analysis of the entire paper,it proposes a feasible solution to eliminate the surface discharge of suspension insulators.
