Research on Heat Transfer by Fluid in Winding Region of Power Transformer

Abstract:

In this paper, a model of the winding area for a normal working oil-immersed power (180MVA, 220kV) was built to conduct the simulation analysis for heat transfer of fluid field. Based on the fundamental mechanisms of fluid mechanics, limited volume method was used to build the model of the winding area of the power transformer. The effect of the oil input velocity, the amount and the position of oil baffle plate were concluded. The reasonable method to control the temperature was purposed by analyzing the heat-transfer properties for different conditions. When the initial oil velocity was 0.3-0.4 m/s during forced oil circulation, the best heat transfer was achieved. For the natural oil circulation, inserting 3 oil baffle plates at the higher temperature winding ends, when the number of the next two oil baffle plates is 7, the heat delivery effect is best.
