低压交流串联故障电弧模型及实验
Model and Experiment of Low-voltage AC Series Fault Arc
摘要
Abstract
Based on circuit theory,by treating arc as an equivalent time-varying resistance,a mathematical model of arc is proposed with arc resistance and load parameters as variables. Arc resistance is regarded as a periodic function of time,and it is partitioned into different regions.Moreover,the mathematical expression of arc resistance in each regio?nis also given.By using this model,the arc currentis calculated at different load levels.The calculated results are com?pared with the simulation results and the experimental results of Cassie and Stokes arc models.The comparison results verify the correctness and practicability of the proposed arc model,indicating that the research in this paper can provide theoretical reference for the diagnosis of low-voltage series fault arc.关键词
