Abstract: In order to study the contamination characteristics of insulator at different voltages, the wind flow field and electric field in sandstorm were simulated based on fluid mechanics theory and electric field theory. The research shows that contamination of insulator is different at different voltages. When the flow velocity around the insulator is small, the voltage at both ends of the insulator increases, which will lead to the increase of the contamination quantity, and the contamination is closely related to the change of electric field force. When the surrounding flow velocity is large, even if the voltage increases, the contamination quantity will not change too much.


Key words: multiple-physical fields, sandstorm, insulator, contamination characteristics
