Abstract

A mathematical model, based on experimental tests, is developed to study and verify the influence of source parameters on the behavior of polluted insulators in AC systems. This analytical model allows users to reproduce and study several experimental characteristics of polluted insulator tests. The additional term included in the Mayr type arc equation to consider dielectric disruption is adequate for the purpose of pollution simulation. The arc ignition and extinction results obtained in simulations are in agreement with experiments. The influence of source parameters on the arc processes was observed with the model. The simulated results allow evaluation of the adequacy of a source to be used in pollution tests.<>

研究污染绝缘子试验中源参数影响的数学模型
在实验的基础上,建立了一个数学模型来研究和验证源参数对交流系统中污染绝缘子行为的影响。该分析模型允许用户重现和研究污染绝缘子试验的几个实验特性。Mayr型电弧方程中考虑介电破坏的附加项足以满足污染模拟的目的。模拟结果与实验结果吻合较好。利用该模型观察了源参数对电弧过程的影响。模拟结果可用于评价用于污染试验的源的适当性。
