摘　　要：针对6种典型的可控电抗器铁心结构,在理论上进行磁场分析,并在有限元分析软件ANSYS(analysis system)中建立其模型,施加不同的激励电流,进行铁心磁场分布的分析比较,采用ANSYS内置的损耗算法,比较了6种铁心结构的损耗情况,验证了对于某种特定的铁心,激励对损耗的影响情况。结果表明,对于不同的电抗器铁心结构,ANSYS能有效分析对比其磁场分布及损耗情况。Magnetic fields of six typical controllable reactors core structures are theoretically analyzed, and by use of a finite element analysis software, namely analysis system （ANSYS）, the models of these six core structures are built; exerting different excitation currents, the comparison and analysis on the distributions of these core magnetic fields are performed; utilizing the built-in algorithm of ANSYS, the losses of these six core structures are compared, thus the influence of excitation current on the loss of a certain given core structure is validated. Research results show that for different core structures of controllable reactors, ANSYS software can effectively analyze the magnetic field distribution and core loss.
