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.
