ABSTRACT:
A transformer is disclosed that includes a housing having a core-winding assembly positioned therein that is immersed in a dielectric transformer fluid contained within the housing. A cooling system is provided to cool the dielectric transformer fluid contained within the housing and includes a closed-loop fluid path having a quantity of dielectric cooling fluid that is circulated there through and that is maintained separate from the dielectric transformer fluid. A liquid-to-liquid heat exchanger is positioned along the closed-loop fluid path and within the housing so as to be immersed within the dielectric transformer fluid, with the liquid-to-liquid heat exchanger cooling the dielectric transformer fluid based on a liquid-to-liquid transfer of heat energy between the dielectric cooling fluid and the dielectric transformer fluid. The cooling system also includes a heat dissipation system positioned remotely from the liquid-to-liquid heat exchanger to cool the dielectric cooling fluid circulating through the closed-loop fluid path.
