Finite Element Analysis of Physical Properties of New Transformer Core Materials

Power transformer is the core equipment which transmits and distributes electric energy in power system. Power grid performance is directly influenced by the performance of the transformer, and the transformer core losses account for the vast majority of the total losses. As a result, the choice of transformer core materials has a significant impact on the overall efficiency of the grid. The objective of this paper was to develop a three-dimensional model of a three-coherent transformer using ANSYS Electronics Desktop software, with PC95 as the core material and a multi-physical field coupling calculation simulation using the finite element mesh method for obtaining the physical parameters of the dynamic change characteristics, thereby enabling the visualization of transformer parameters. The magnetic field distribution and core loss of the transformer were simulated and compared with those of different core materials (PC44). According to the results of the study, the permeability of PC95 material is much greater, the loss of transformer core is much lower, and the temperature adaptability is greater than that of PC44 material. And it is more adaptable to the effects of temperature change, the optimization design of transformer in the environment of large temperature difference provides theoretical basis, so as to improve the efficiency of the transformer more effectively.
