Abstract :
The hotspot temperature-rise of transformer winding is an important winding temperature indicator (WTI), but it is difficult to calculate in design. The "porous" medium value method of calculating a large scale boiler and the reactor hot conductor of atomic energy is used to calculate the flow and temperature field of a transformer winding, which is the new method for estimation of hotspot temperature-rise of the transformer winding. The experiment makes extensive use of the "porous" technique on a transformer winding model which is effective, so pads for calculation to exceed the hotspot temperature-rise of the transformer winding of high capacity decides the foundation
