针对故障电弧研究需要搭建专门的实验环境来分别模拟串联故障电弧、并联故障电弧和接地故障电弧而存在费用较高、实际操作比较困难的问题,提出了一种能在Matlab7软件中工作的Mayr电弧模型的设计方案；介绍了Mayr电弧模型方程的物理意义,采用Mayr电弧模型封装子系统对低压交流线路发生的串联故障电弧进行了仿真,并根据仿真电路,模拟了低压交流线路发生串联故障电弧的实验.仿真及实验结果表明,Mayr电弧模型的故障电弧电流与实验采集到的故障电弧电流比较接近,采用Mayr电弧模型用于低压交流线路故障电弧仿真具有一定的可行性.%In view of problems of high cost and difficult operation in practice because fault arc's research need build special experimental environment to simulate series fault arc, parallel fault arc and grounding fault arc, the paper proposed a design scheme of Mayr arc model which can work in Matlab7 software. It introduced physical meaning of Mayr arc model equation, makes simulation of series fault arc happened in low-voltage AC line by use of Mayr arc model packaging subsystem, and simulates experiment of series fault arc happened in low-voltage AC line according to simulation circuit. The results of simulation and experiment showed that fault arc current of Mayr arc model is similar to fault arc current collected by the experiment, so it has certain feasibility to use Mayr arc model in simulation of fault arc of low-voltage AC line.
