Abstract This paper studies on charge transport mechanism and space charge characteristic in polyimide film based on measuring and comparing space charge accumulation threshold field between corona-resistant and common polyimide film and analyzing the effect of temperature on space charge distribution. The results reveal that space charge accumulation threshold field of corona-resistant polyimide film is higher than that of common polyimide film; the adding of nano-particles effectively increases dielectric properties of corona-resistant film. Additionally, raising temperature promotes the electrode injecting charge and increases the charge energy and conductivity which gradually enhances space charge number and extends trapping position into the bulk, closely related to polyimide film insulation aging and breakdown which is an important characteristic.

Key words： Polyimide film charge transport space charge aging
