Oil-immersed insulating material has an anisotropic and nonlinear conductivity, so the direct current (dc) electric field calculation should take these factors into consideration. In this paper, a new calculating method based on ANSYS secondary development technology is proposed. Then, the nonlinear and anisotropic dc electric field is calculated, considering electrical stress and temperature impact...
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; The model is calculated and analyzed in the load of short-circuit test, the maximum deformation 2.62 mm of disk obtained is mainly consistent with actual measured value 2.9 mm; Analysis...
