摘要：

分析磁阀式可控电抗器（MCR）的主要工作原理,介绍三相六柱三维式MCR的铁心结构和MCR铁心损耗的主要来源.从磁通密度的角度出发,将三维式铁心结构和传统平面式铁心结构进行对比,分析铁心中的磁路分布,介绍三维结构铁心减少损耗的主要机理.三相三维铁心结构的MCR采用并联式磁阀,利用磁阻材料和硅钢片混合堆叠,可以缓解由于磁阀处铁心饱和而产生的边缘效应,降低磁阀处的漏磁,进而减小磁阀边缘处的涡流损耗.使用Ansoft电磁场仿真软件对平面和三维2种类型的MCR进行磁场分析,研究铁心磁轭和磁阀中的磁通密度曲线,对比并联磁阀和传统磁阀表面位置的磁通密度分布.仿真结果表明：三相六柱和并联磁阀结构可以使磁通分布得到优化,进而有效减小MCR的铁心损耗.所采用的磁损特性研究方法同样适用于其他类型的可控电抗器.
Abstract:

The main working principles of magnetically controlled reactors (MCRs) were analyzed. The 3D iron core structure of the three phase hexastyle MCRs and the main sources of iron core loss were introduced. From the perspective of magnetic flux density, the 3D iron core structure were compared with the traditional 2D iron core structure. The distribution of magnetic circuit in the core were analyzed, and the mechanism of 3D structure to reduce core loss were introduced. Parallel magnetic valves were used in the three phase 3D iron core structure, with magnetic resistance materials and silicon steel sheets piled up together. The parallel magnetic valves can reduce the edge effect caused by magnetic valve saturation, thus reducing the magnetic flux leakage and the eddy current loss at the magnetic valves. Magnetic analysis of the 3D and traditional 2D iron core structure was taken using Ansoft software. The flux density curve in magnetic yoke and the magnetic valve of iron core were studied, and the magnetic distribution of parallel magnetic valves and traditional valves were compared. The simulation results show that the new iron core structure can optimize the magnetic field distribution, thus reducing the iron core loss of MCRs. The research method of magnetic loss characteristics can also be used in the analysis of the other types of controlled reactors.
