摘　　要：可靠的电流互感器铁芯磁化模型对于铁芯的剩磁和饱和问题研究具有重要意义。文中建立了一种基于堆栈操作的新型电流互感器铁芯磁化模型。归纳分析了铁芯磁化的规律,对磁化曲线进行了分类,根据磁场强度H的变化和压栈、出栈操作来确定铁芯磁化曲线的类型,系统地给出了计算相应磁通密度B各类曲线的B-H关系式,仿真结果与实验的比较验证了模型的准确性。The reliable magnetization model of current transformer core is of importance for the study on residual flux and saturation of the core.In this work,a new magnetization model of current transformer core based on stack operating is presented.The magnetization characteristics of the core are summarized,the classification for the existing various magnetization curves is completed,and the category of curves is determined in accordance with the variation of magnetic field intensity H and stack operating.Corresponding to various categories of B/H curves,the systematic expressions of calculating magnetic flux density B are given.The comparison between the B values calculated with the present model and the experiments verifies the accuracy of the present model.
