REDUCTION OF LOCAL HEATING IN TANKS OF POWERFUL TRANSFORMERS BY HEAT-REMOVING LOCAL RADIATORS WITH RIBBED

The main approaches, the results of numerical modeling, and examples practical application heat-dissipating radiators made aluminum, with a flat base, ribbing to reduce local heating in ferromagnetic covers walls transformer tanks, which arise cases concentration magnetic fluxes from multi-ampere taps or shunts are presented. case thermal coupling non-magnetic flange yoke beam base radiator (copper plate) is considered, shows possibility reducing using conductive heat transfer between shelf plate convection their surfaces cooling oil.
