Abstract Particle diameter distribution on insulator surface has important influence on the surface leakage current and pollution flashover voltage.The adhesion process of particle was simulated based on computational fluid dynamics and collision model, and the influences of different factors were studied. The results show that under typical meteorological conditions, the diameter distribution of adhered particles on the porcelain insulator surface has a statistic characteristics, which is mainly distributed in 5~50μm. In addition, relative humidity and wind speed have a significant effect on diameter distribution. The effects of aerodynamic type, electric field type and electric field strength are relatively weak. This work can provide powerful support for further research work on contamination simulation experiment and influence of particle diameter on pollution flashover.

Key words： Porcelain insulator contaminated particle particle diameter distribution characteristics collision adhesion model
