在研究配电网的电弧接地故障、断路器投切电弧及电弧炉电气特性时，多数学者通常使用恒电阻、Cassie、Mayr 电弧模型，三者都具有片面性，将 Cassie 与 Mayr 两个电弧模型结合使用可以达到互补。在 ATP －EMTP 平台下将两种电弧模型进行组合搭建，并合理设置参数，通过在中性点非有效接地10 kV 配电网下的仿真，研究分析了电弧的电压分布、过零点、伏安特性，证明该电弧模型可正确反映中性点非有效接地配电网故障电弧特性。

When studying arc grounding fault of the distribution network,breaker switching arc and electrical characters of the arc furnace,most scholars use three arc models of constant resistance,Cassie and Mayr,all of which are one-sided.Combination of Cassie and Mayr models may complement each other.This article combines those two arc models on the ATP-EMTP platform and sets parameters in a reasonable way.Through emulation of the neutral point non-effectively grounded 10 kV distribution network,it studies and analyzes the voltage distribution,zero crossing and volt-ampere characteristics of the arc,and proves that this arc model can correctly reflect the fault arc characteristics of the neutral point non-effectively grounded distribution network.
