【 摘 要 】

The metallurgical industry in China has developed rapidly, which has caused an increasing amount of exhausted gas emission. After a long period of operation, a layer of metallurgical contamination is deposited on the surface of insulators near the metal work, which may have an effect on the distribution of electric field on the surface of insulator. The chemical test indicates that the metallurgical contamination layer contains particles of Fe3O4with strong conductivity, which may become suspended potential conductor. In this paper, the influence of thickness of contamination layer and diameter, arrangement of conductive particles on the electric field are discussed by the simulation model.
