Abstract
Surface flashover characteristic of epoxy resin composite material in SF6/CF4 mix gas were studied through experimental method, and the influence of several key parameters were analyzed, such as gas pressure, SF6 mix ratio and voltage polarity. It is shown that, when the mix ratio of SF6 in the mixed gas is 40%, the flashover voltage of epoxy resin insulator can reach over 60% of the flashover voltage in SF6 with the same pressure. The synergistic effects in the needle-plate electrodes system have significant difference between positive and negative polarity. The synergistic effect for negative polarity is weaker than that in negative polarity. Comprehensive environmental requirements and surface flashover characteristics, the results provide a potential SF6 alternative for GIS equipment.
