Research on Transformer Winding Deformation Based on Multi Physics Field Coupling Theory
In order to analyze the state characteristics of transformer windings more accurately,this paper proposes a finite element research method based on the"electric magnetic structure sound"multi physical field coupling theory.The change law of the entire process from power excitation to winding vibration sound response under normal working conditions of transformers is modeled and simulated.In particular,a three-dimensional finite element analysis model based on transformers is constructed,and multi physical field coupling simulation calculations are carried out to obtain the voiceprint characteristics of different deformation types of windings.
