Abstract


At present, most of voltage transformer insulation designs of products adopt traditional design method, the cycle of the design is long and quality of the design product is poor. Modern design method of reliability theory from the design stage will be introduced to the product, to greatly reduce the cost of design, manufacturing, economize resources, and improve the design efficiency, therefore has the good economic efficiency and the social efficiency. In this paper, Using finite element analysis and stress—strength interference theory and reliability design of design method based on the voltage transformer insulation optimization design of insulation scheme, make the products more reasonable in economy.This paper analyzes the present situation on the design of the voltage transformer insulation, described the different voltage transformer insulation structure, summarizes the aging mechanism of the insulation material, and discusses the influence aging mechanism of various factors of insulation aging. By using stress—strength interference theory, it directs reliability calculation formula of normal distribution. Based on the electric voltage transformer insulation, heat stress analysis, design for the reliability insulation. And with the example of lOkV voltage transformer, using ANSOFT software simulation model is established for electric field and temperature field, the 3D simulation computation. Use of MATLAB software editing Fallou electricity - hot joint aging formula, draw the joint aging formula different parts of the transformer insulation aging rate image, and identify voltage transformer insulation weak parts. According to the simulation results, the occurrence of voltage transformer part of the electric field distortion coil was used to optimize the way round to improve the distortion of the transformer part of the electric field, so that greatly reduced the electric field distortion. Finally using 3D simulation of insulation aging rate image rendering, identify different parts of voltage transformer insulation intensity.
