Electric field calculation and optimization for stress cone of DC cable joint based on the coaxial double-layer insulation model
IEEE Transactions on Dielectrics and Electrical Insulation(2020)
摘要
This paper presents a DC electric field calculation and optimization algorithm for a coaxial double-layer insulation. The stress cone curve of a 320 kV DC cable joint was optimized utilizing the algorithm under different conditions. The obtained results show that the stress cone curve becomes steeper with an increase of the x-axis electric field. The curve also becomes steeper with a decrease of t...
