Study on Simulation Test Device of Transformer Split Type Cooling System

Abstract The structure, cooling principle and operation characteristics of transformer split type cooling system was different from conventional cooling systems. Such as the research work of simulation test equipment in the field was few, causing a lack of scientific basis for the equivalence of simulation test, and parameters set of split type cooling system without scientific and professional analysis. The result is that so many features and operation characteristics were not fully grasped before. Therefore, it was necessary to carry out the corresponding research work. The experimental study was carried out in this paper. This paper would research the simulation test method of split cooling system based on a 10kV distribution transformer. The test device can realize the flexible regulation for the vertical and horizontal position. According to the temperature-rise test method of transformers, performance test of split type cooling system was carried out based on the change of oil flow or radiator location. Finally, the research results of different pipe diameter, height and horizontal distribution were proposed. The study would provide more references for operation instruction of large power transformer's split type cooling devices.
