flux density map of dry-type transformer core will be obtained using the ANSYS
software simulation, which is shown in Fig3. The specific steps and mode of
operation is as follows:
(1)
Electromagnetic physical parameters were read into the software to solve and
analyze: GUI: Main Menu>Solution>Current LS;
(2)
The temperature and volume force were reading into the software to assignment
the material properties: GUI: Main Menu> Preprocessor> -Loads-> Apply>
Temperature> From Thermal Ana.
(3)
Re-point ESAV and EMAT files using ASSIGN command in order to prepare
the transient thermal analysis restart: GUI: Utility Menu> File> ANSYS File
Options;
(4)
The physical environment was reading into the thermal analysis: GUI: Main
Menu> Preprocessor> Physics Environment> Read;
(5)
Joule heat was reading out from the electromagnetic analysis: GUI: Main Menu>
Preprocessor> -Loads-> Apply> Heat Generat> From Mag Ana;
(6)
Solving the transient thermal analysis by default time increment; Re-default to
the file: GUI:Utility Menu> File> ANSYS File Options; Repeating the previous
time step in the next time increment.
(7)
One can achieve the temperature field solution if the results of magnetic field
analysis obtained by the heat generation rate had been taken as a reading file.

The temperature field simulation process is iterative process, the result of the
thermal analysis shown in Figure 4. In Fig 3 and Fig 4, if the magnetic field and
temperature field at each location are separated in groups depending on the value,
then given color where the highest value are red and the lowest blue.
