Abstract The pollution particle depositing and moving process on DC transmission line energized insulator will be obviously affected by its surrounding electric field. Currently, energized insulator contamination rules and the corresponding mechanism are not fully revealed yet. In this paper, taking XP-160 typical suspension insulator as the object, its DC contamination tests under various wind velocity and pollution particle diameter were carried out using wind tunnel platform. The DC contamination performances were analyzed. The discrepancy of pollution degree between DC energized insulator and non-energized insulator was obtained. Then combining with field charging theory, t the bearing forces of pollution particles were calculated and analyzed, and the variation of the particles’ moving process as well as their moving speed by DC electric field were studied. Finally the effects of insulator DC electric field on its contamination were revealed.

Key words： Insulator contamination wind tunnel test DC electric field
