摘要：
When it comes to safety accidents in power system, pollution flashover often causes more economic loss because of its large impact area and long impact time. To understand the contamination characteristics of insulators and predict the state of pollution, a typical insulator's contamination model in wind tunnel was established with Multiphysics simulation software, and a feature particle tracking method was proposed based on sample survey and feature particle analysis. The unitary pollution characteristics of insulator can be judged from the weighted average tracking results of sample particles with single particle size and charge amount. Based on this foundation, the effects of AC and DC electric fields were taken into consideration to analyze the influence of different kind of electric field on insulator contamination. The simulation results show that DC electric field has a significant effect on insulator fouling under the condition of weak wind and large particle size.
