Abstract

The purpose of this study was to validate a designed three phase power transformer with modern software that use finite element method, by analyze it from two points of view: magnetic and thermal. For that, on the analysis it will be used two modules from ANSYS software, ANSYS Maxwell 3D and ANSYS Mechanical, both coupled in the same environment, ANSYS Workbench. It has used the latest versions from ANSYS, Workbench 14.5 and Maxwell 3D 16. [1] On the same time, it can be seen the 3D magnetic nonlinear behavior of this three phase power transformer and thermal effects for the ferromagnetic core. Also it can be found the magnitude of B field, the regions with problems and the value of the total core losses for the same transformer but at 3 types of voltages: 330 kV, 400 kV and 430 kV.
