基于迭代计算的介电功能梯度绝缘子电场优化研究OA

Dielectric gradient insulators can optimize the overall electric field distribution and increase the surface flashover voltage without changing the geometric structure.Based on classical electromagnetic field theory,obtain the electric field distribution characteristics and optimization principle of gradient in-sulators.Aiming at reducing the maximum field strength along the surface of pot insulators,an iterative calculation based electric field optimization design scheme for pot insulators is proposed.Combining the principle of electric field optimization and iterative algorithm process,comparative analysis is conducted on the electric field optimization effect of the design scheme by analyzing factors such as the number of layers,upper limit of dielectric constant,and surface thickness.The simulation results show that com-pared to homogeneous basin insulators,the maximum field strength of the body/surface gradient basin in-sulators decreases significantly along the surface,reaching up to 34.37％and 39.08％respectively.The optimization effect is significant,and the uniformity of electric field distribution is greatly improved.
