研究了不溶性或惰性污秽物对高压户外瓷绝缘子闪络电压的影响。本文对先前提出的预测水溶性污秽瓷绝缘子闪络电压的电弧动态模型作了适当的修正。扩展模型已被用来预测的闪络电压的各种形状的悬式和站支柱绝缘子的交流和直流电压。与实验数据有很好的相关性。该模型可作为高压瓷绝缘子设计和维护的计算机辅助工具。
The influence of non-soluble or inert contaminants on the flashover voltage of HV outdoor porcelain insulators is examined. A dynamic arc model, presented earlier for predicting the flashover voltage of porcelain insulators covered with water soluble contaminants, has been modified suitably. The extended model has been used to predict the flashover voltage of suspension and station post insulators of various shapes for both ac and dc voltages. Good correlation with experimental data has been shown. The model can thus be used as a computer aided tool for design and maintenance of HV porcelain insulators.
