A CALCULATING METHOD OF TEMPERATURE RISE IN A SELF-COOLED OIL-IMMERSED TRANSFORMER FOR ELECTRIC TRACTION LOADING

Generally, temperature rise in a self-cooled oil-immersed transformer is treated as proportional to 0.8 power of its loss. But there are some problems in application of this treatment to thermal calculation of the transformer for electric traction loading which fluctuates violently. Many thermo-couples were inserted in a test transformer for measurement of its thermal characteristics, and a calculating method of the temperature rise in the transformer is studied under several operating conditions.
