摘要：

Large wound core transformer has been gradually applied in the railway system. The modeling analysis of eddy current field is the basis of the design and optimization process of wound core transformer. However, the existing modeling method for the laminated core is not suitable for the wound core. Firstly, based on the appropriate modification of the original anisotropic equivalent conductivity formula with reference to the structure of the wound core, a new 3D eddy current field modeling method applicable to the wound core was proposed. Secondly, taking the calculation of the eddy current loss of the core as an example, the validity of the proposed model was verified by the classical eddy current loss formula while the eddy current field of the core was simulated and analyzed. At last, the eddy current loss of the OD-R-32000/55 wound core autotransformer was calculated and compared with the measured value to verify its engineering applicability. The results show that the proposed model can effectively calculate the eddy current loss of the wound core, and has good field applicability. © 2021, Department of Journal of the China Railway Society.
