摘要:
为了较全面地了解RTV涂层对绝缘子电场分布的影响,使用有限元法建立绝缘子模型进行数值计算,分析了RTV涂层的厚度、介电常数以及非均匀喷涂方式对10 kV支柱瓷绝缘子导线附近和支柱表面电场分布的影响。结果表明:绝缘子电场的分布不但受涂层厚度的影响还受涂层喷涂形状的影响,合适的喷涂方式有利于改善绝缘子电场分布; 随着涂层厚度的增加,涂料的介电常数对绝缘子电场分布的影响程度也越大。所得结果可为绝缘子涂层的优化提供新的理论依据。
Abstract:
In order to fully understand the influence of RTV coating on the electric field distribution of insulators, the finite element method was adopted to establish an insulator model for numerical calculation. The influence of the thickness, dielectric constant and non-uniform spraying method of the RTV coating on the distribution of electrical field near the insulator and the pillar surface of the 10 kV pillar porcelain insulator was analyzed. The results show that the distribution of electric field of insulators is influenced not only by the thickness of the coating but also by the shape of the coating. The suitable spraying method is beneficial to the improvement of the electric field distribution of insulators. With the increase of coating thickness, the influence of dielectric constant of coating on the electric field distribution of insulator is greater.The study result isa new theoreticalbasis for the optimization of insulator coating.
