NEW DESIGN OF TRACTION TRANSFORMERS FOR FIXED INSTALLATIONS
In this paper an analysis of different designs of traction transformers is given. The paper describes three-limb transformer design for 7.5 MVA and 10 MVA units and two-limb transformer design for 15 MVA and 16 MVA units. Paper also represents noise level measurement results and sound intensity frequency spectrum for 16 MVA unit. Based on results of measurements taken during heat run test on transformer loaded with continuous load equivalent to rated power, simulation of oil and winding temperatures is given for two most common overload cycles of traction transformers. The paper also gives a description of design and technological measures necessary in case of need to prepare the transformer for short-circuit withstand test, including the procedure and results of tests successfully performed at KEMA High Power Laboratory.
