In this paper, taken the deep-sea transformer as the research goal and based on the numerical model method, the finite two-dimensional numerical model of deep-sea transformer is established by ANSYS and the leakage magnetic field and winding loss of the transformer are calculated. Then based on the two-dimensional numerical model, a three-dimensional model is established to solve the winding losses and verify the accuracy of the two-dimensional loss solution results. The analysis results show that the leakage magnetic field distribution and winding loss of the transformer obtained by the three-dimensional numerical model method are similar to the calculation results of the two-dimensional numerical model, which further verifies the accuracy of the finite element numerical calculation method in the calculation of the electromagnetic characteristics of deep-sea transformers With usability.
