Abstract

The post porcelain insulator is pulled by bus, which will produce stress in post porcelain insulator, and stress concentration is in the root of the umbrella. Therefore, there will be break accident if it is not installed properly. Firstly, the fracture theory of porcelain insulator is summarized from the characteristics of ceramic materials, including its way to fracture and the characteristic quantities emerged when fracturing. Then the brittle fracture theory of the maximum tensile stress theory of the porcelain insulator is summarized. The ANSYS based on finite element method is used for simulation analysis. The finite element model of different types of porcelain insulators is established, the stress distribution of the porcelain post insulator in different directions and of different sizes are calculated. The maximum stress value of the structure of the umbrella skirt is changed correspondingly by changing the direction and size of the force of the bus line. The relationship between stress and load force mainly presents a linear relation with load. According to the calculation of the stress distribution of the porcelain insulator using finite element method, the relationship curves of stress and load direction and magnitude are plotted, and the theoretical results are verified.
