摘　　要：基于电弧电流与磁场分布的对应关系,提出了一种通过蚁群算法来反演电弧电流分布的有效方案。将电弧磁场定义为电流线磁场的叠加,依据磁场分布和电流线与磁场的关系,利用求解线性方程组得到电流线分布初值;最后,利用改进的蚁群算法,对电流线与磁场之间对应关系进行精确拟合,反演二维情形下的电弧面电流密度分布。Based on the corresponding relation of arc current and magnetic distribution, this paper proposed an effective scheme to invert the distribution of arc current by arc colony optimization. The arc magnetic field is defined as the super position of current line magnetic filed, according to the relation of magnetic distribution and current line and magnetic field, the original value of current line distribution is obtained by solving linear equations. At last, the improved ant colony optimization is used to accurately fit the corresponding relation between current line and magnetic field to invert the 2D distribution of arc surface current density.
