大型变压器线圈涡流损耗的有限元计算

Application of Finite Element Method in Calculting Eddy Current Losses of Transformer

采用线性轴对称正弦稳态场的有限元法对变压器线圈的涡流损耗进行了研究,并对实际产品进行了计算。编制了适用于任意计算场域的自动剖分程序,正弦稳态场的计算程序,涡流损耗的计算程序。

In this paper,the finite element method is used to study linear sinusoidal axisymmetrical magnetic field and eddy current losses in the transformer winding.The method is used to calculate the eddy current losses in some practical products. The FORTRAN programs are generated for the auto-mesh-generation up to arbitrary shape domain,computation up to stable sinusoidal magnetic field and eddy current losses in steady state.
