Analysis on Electric Field Distribution of ±1000kV DC Wall Bushing with Considering Space Charge
Based on space charge theory, electric field and potential distribution of ±1000kV DC wall bushing under DC and AC work condition is analyzed in this paper. The position and amount of space charge can be deduced from space charge theory and surface charge theory. By analyzing electric field and potential distribution under DC and AC voltage work condition with and without space charge, valuable conclusions are drawn, which provides valuable reference for insulation design.
