| Abstract: | Based on the boundary condition of transformer''s oil parameter and transformer radiation heat loss, ANSYS is used to conduct simulation analysis of a 630 kW/10 kV transformer with nature cycle-oil cooling method. A conclusion can be made from simulation result that with the increase of load, the winding temperature increases sharpest, and hot spot is located at the 85% vertical height. |
