Analysis of Transformer Winding Deformation Based on Magnetics-structure Coupled-field

Abstract

In this paper, the transformer magnetic-structure coupled model is established based on the finite element method, and the simulation of electromagnetic field and structural field of the transformer is carried out. The frequency response method, the short circuit resistance method and the winding capacity method are used to analyze the winding deformation and verify the correctness of the simulation model by comparing the test results.
