【Abstract】 Basin insulator is an important insulating component of high voltage gas insulation equipment, its performance directly affects the stable operation of high voltage equipment. For the basin insulator, enhance the uniformity of electric field distribution as the optimization goal, based on the method of finite element iterative calculation, the comprehensive optimization scheme of electric field of basin insulator is proposed. The structure of the basin and the dielectric constant of the gradient material are changed by the optimization algorithm, obtain the optimal electric field distribution of insulator. The simulation results show that, comparison of homogeneous basin insulators, under the condition of mechanical properties, after comprehensive optimization, the maximum field strength drop of concave and convex surface of body and surface gradient basin insulator is 35.79%、30.59% and 29.28%、29.51%, the optimization effect is remarkable.更多还原
