Abstract：The contamination deposition characteristics of typical shed porcelain and composite insulators can be used in the insulator selection. Using multi-physics coupling software, numerical simulations on the contamination features of porcelain bell jar, porcelain three umbrella, and composite insulators in a wind tunnel were conducted, and the simulated results were compared with the tested results. The comparison shows that the results with respect to the deposit amount are at the same order of magnitude and present a similar tendency with DC voltage variation. Therefore, the rationality of the present simulation method is verified. Based on the aforementioned method, a simulation investigation of the natural contamination deposition on the above three insulators was performed to examine the effects of wind speed, particle size, and voltage type. The results indicate that under the same conditions, the deposit amount on the composite insulator is greater than those of both the porcelain bell jar and porcelain three umbrella insulators. It is found that under DC voltage, the growth rate of the pollution amount on composite insulator is greater than those of two other insulators, and it first decreases and then increases with increasing particle size. At the same wind speed, the influence of the voltage type on the insulator contamination increases as the particle size increases. In addition, the deposit amount under AC voltage and unelectrified state is less than that under DC voltage.
