| 摘 要： | 利用矢量磁位的扩散方程，建立了求解大型电力变压器三相套管升高座涡流损耗的数学模型，根据几何形状的对称性、边界条件和库仑规范约束条件，提出解的级数形式，直接应用分离变量法进行求解，最后用算例对该方法进行验证，计算值与测试值吻合较好．

| Abstract: | A mathematical model is developed to analyze eddy current losses in enclosures of large capacity transformers due to leading current. Use is made of the diffusion equation for the magnetic vector potential. A series solution is obtained depending on the symmetry of the geometric configuration, the boundary conditions and Coulomb gauge. The calculated with test results show that the proposed model yields reasonable results. |
