Abstract

Plenty of solid products will be produced when the arc discharge fault occurs in SF6 gas-insulated electrical equipment, which will extremely threaten the internal insulation properties of the equipment. Therefore, it is necessary to carry out research on the solid products formed by the reaction of SF6 with metal electrode under electric arc, aiming to study their effect on the operation of the equipment. First of all, the formation characteristics of the solid products with different metal electrodes and different pressures are studied. Then, the composition of the solid products is determined. Besides, the quantitative relationship between the mass of the solid products and the discharge energy is analyzed as well.
