为了降低取向硅钢片组成的三相电抗器的铁损，提出了两种电抗器模型。一种是在支腿与轭架之间采用斜接头，另一种是在L、T接头处采用无取向（NO）硅钢片组成的对接接头。所提出的模型的目的是放松内的铁芯，由于各向异性的磁特性的GO硅钢片发生磁通集中。通过考虑铁芯各向异性磁特性的磁场和铁损分析，研究了所提出模型的有效性。结果发现，磁轭中的磁通集中可以放松在这两个模型。在L形和T形节点处不加钢板的模型比普通模型的铁损降低约12%。
To reduce the iron loss of a three-phase reactor composed of grain-oriented (GO) silicon steel plates, we proposed two reactor models. One applies oblique joints between the legs and the yokes, and the other applies butt joints composed of non-oriented (NO) silicon steel plates at the L and T joint parts. The proposed models are aimed to relax the flux concentration inside the iron cores that occurs due to the anisotropic magnetic characteristics of GO silicon steel plates. The effectiveness of the proposed models are investigated through magnetic field and iron loss analyses considering the anisotropic magnetic characteristics of the iron cores. It is found that the flux concentration in the yoke can be relaxed in both proposed models. And iron loss of the proposed model with NO steel plates at the L- and T-shaped joints can be reduced about 12% compared with the ordinary one.
