N2 - As important electrical-mechanical components of gas insulated transmission line (GIL), insulators face challenge from surface flashover due to the accumulation of surface charge. To promote the insulating property of insulators, surface functionally graded material (SFGM) produced by fabrication and modification is necessary to dissipate surface charge and inhibit the flashover. In this paper, a surface dielectric barrier discharge (SDBD) reactor for the surface functionally graded modification of epoxy resin (EP) was proposed, and the physicochemical properties of the EP surface were analyzed to investigate the modification effect. The results show that the a large-area discharge is generated under the nanosecond power supply, and the EP surface becomes rough and a large number of silicon-containing groups are introduced on it. Furthermore, the accumulation of surface charge and surface flashover are both inhibited after the plasma modification, which indicates the improvement of insulating property by SDBD treatment.
