This paper processes simulate analysis of short-circuit test model of transformer
using finite element analysis software ANSYS.The winding and disk deformation is calculated in different elastic modulus value of strip;By changing the size of strip circumferential direction
radial displacement of disk is calculated corresponding to the four strip size;The model is calculated and analyzed in the load of short-circuit test
the maximum deformation 2.62 mm of disk obtained is consistent with actual measured value 2.906 mm.This analysis method in paper can be used for large power transformer winding short-circuit strength and radial stability analysis.
