Comparative Analysis of Simulation and Analysis of Bubble Motion Characteristics in Transformer Oil Based on Horizontal Set Method and Phase Field Method

Large power transformer is the key equipment for realizing energy transmission and voltage conversion in system, but actual operation, its internal oil prone to cause partial discharge of suspended bubbles due various factors, which endangers safe operation transformer. Therefore, this paper conducts simulation research on generation mechanism motion law oil, first all, based Comsol software, model constructed, considering degree distortion regular characteristics trajectories under different bubble number, initial position, size, other influencing then comparing analyzing difference between results horizontal set method phase field two interface tracking methods, finally obtaining multi-faceted multiple physics.
