Abstract :
In this paper, DPF1-240MVA/500kV type power transformer as the research object, according to the structural characteristics, a 3D numerical simulation model is established. Through the calculation results and the analysis of the distribution cloud map, compare with different support structures programs for the effects of winding axial vibration, Obtained proportional relationship between preload, Pads material elasticity coefficient, quantities, sizes and natural frequency. On this basis, the engineering guidance will be given.
