Abstract  

With the rapid development of high voltage DC (HVDC) transmission in China, the surface charge accumulation under the DC voltage has been a serious threat to the safety and reliable operation of HVDC system. In this paper, an atmospheric pressure plasma jet was introduced to deposit SiOx films on epoxy resin surface to accelerate the dissipation of surface charge on insulating material. The reaction precursor was TEOS. The multi-parameters were analyzed before and after plasma modification, including chemical composition, surface conductivity, surface charge distribution, trap depth and voltage endurance. The results showed that a large number of inorganic groups including Si-O-Si and Si-OH groups were introduced on epoxy resin surface, and the surface conductivity increased by 2 orders of magnitude. With the increase of the modification time, the initial accumulation surface charge decreased and the dissipation rate was accelerated. The energy trap depth became shallower after plasma treatment. Besides, the flashover voltage increased to a maximum value of 9kV at 180s. It is shown that atmospheric pressure plasma jet deposited SiOx film on the polymer surface is an effective method for improving the electrical properties of epoxy resin, and provides an effective modification method for industrial application.
