摘要：

1ABSTRACT: The optimization of the structural parameters ameliorates the electric field distribution characteristics of the electric fittings. Therefore, by selecting the model parameter in the orthogonal experiments, we establishes the plane test model using the finite element analysis software ANSYS to study the electric field distribution influenced by the radius of the pendulum, the length of swing arm and the angles of the swing. In the range analysis, it can be seen that the radius of the pendulum is the most influential factor, followed by the swing arm length and the swing angle. The variance analysis results show that the most significant influences are the radius of the pendulum and the length of the swing arm, while the swing angle has no sense. Though the calculations, a corona test is carried out. The tendency of the corona inception and extinction voltage with the arm length and the pendulum radius diameter is obtained. The applied selection in the areas of 2km and below above the sea level is also obtained. The research results provides the reference data for practical engineerings and selections of the UHV transmission lines. © 2023 Power System Technology Press. All rights reserved.
