摘要 自然环境下绝缘子表面污秽分布复杂多样,这与绝缘子表面的污秽颗粒沉积情况直接相关。绝缘子表面积污是污层不断积累的过程,主要依靠颗粒与污层之间的相互作用。目前有关研究大都以污秽颗粒与绝缘子光滑清洁表面的碰撞粘附作为积污的判定,这与实际情况存在差异。以绝缘子表面非洁净的粗糙表面为研究对象,基于碰撞动力学,分析颗粒之间的聚团和分离过程,建立污秽颗粒积聚模型。进而通过该模型对绝缘子表面积污过程进行仿真计算,得到绝缘子表面积污特性。最后通过风洞积污试验对仿真结果进行验证。研究结果表明,所提污秽颗粒积聚模型较好地再现了绝缘子表面积污情况。

Abstract:The pollution pattern of natural contaminated insulator is very complex and directly associated with the process of pollution particle deposit on insulator surface. Insulator surface contamination is actually the process of pollution layers accumulating, which mostly depends on the interaction between pollution particle and pollution layer. But in relevant researches, the pollution deposit criterion is mostly determined by the collision and adhesion of pollution particles and smooth clean insulator surface. Taking the polluted and rough insulator surface as the research object, this paper analyzed the process of particle agglomeration/separation based on collision dynamics, and subsequently proposed the pollution particle accumulating model. Using the model, the simulation of insulator surface contamination process was presented, and the performance of insulator surface pollution was obtained. Finally, wind tunnel pollution test was carried out to verify the simulation results. It is indicated that the proposed model can well reproduce the pollution deposit situation on insulator surface.
