摘要

污绝缘子闪络机理的研究对电力传输的可靠性、效率和适用性具有重要意义。本文提出了一种基于Ayrton电弧电压梯度方程的新的数学模型，该模型考虑了污染绝缘子的总电阻而不是污染电阻值。导出了绝缘子总电阻的表达式。该模型得到的临界闪络电压(CFV)值与实验结果吻合良好。

Flashover phenomena of polluted insulators energized by AC voltage

The study of polluted insulator flashover mechanism very important for electric power transmission reliability, efficiency and serviceability. In this paper, a new mathematical model based on Ayrton arc voltage gradient equation, which takes account of total resistance of the polluted insulator rather than the pollution resistance value has been proposed. The expression of total resistance of the insulator is also derived. The value of critical flashover voltage (CFV) obtained from the model is in good agreement with the ones obtained through experimental results.
