Abstract: With rapid requirement for energy, off-shore production systems of oil and gas have become important in ocean engineering technology, in which subsea power transformer is an important complement equipment. Subsea power transformer operating in deep ocean should settle some key matters such as higher pressure, seal, anti-corrosion, high reliability, maintenance-free long-period. According to working environment of transformer, design method and structure are put forward in this paper. Titanium alloy is selected to form transformer case, and the pressure compensator is designed. In order to ensure the reliability and reliability of underwater transformers, various measures such as pressure compensation, sealing, temperature control, anti-corrosion, and working state monitoring are adopted. Then cabinet is analyzed using the finite element analysis software Abaqus at different water depth conditions to verify that the structural strength of the transformer cabinet meets the safety permission requirements.Abstract: With rapid requirement for energy, off-shore production systems of oil and gas have become important in ocean engineering technology, in which subsea power transformer is an important complement equipment.

Abstract: 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.Abstract: 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.
