摘要

A theoretical model considering the dynamic change of surface charge accumulation in transient and steady states is proposed. The surface charge accumulation under transient and steady states are simulated using three model spacers with different volume conductivities. The results show that on the convex surface of a spacer, when the volume conductivity is lower than 2 × 10^-18 S/m, the hetero-polarity charge accumulated on the spacer surface is dominant, while the homo-polarity charge accumulated on the surface is dominant when the conductivity is higher than 6 × 10^-17 S/m. The surface charge density is non-uniformly distributed, and the time duration of the transient process of the surface charge density at different positions on the spacer surface is different, due to the distribution of electric field lines. It is hopefully that the content of this paper can provide reference for the mechanism study of gas-volume interface charge transport and the preparation of HVDC spacers.
