Abstract: Using the 30kV·A transformer heat dissipation simulating experiment table, the temperature field distribution of the transformer oil inside the experimental device and the characteristics of the temperature distribution were obtained. The analysis on the results shows that to use the heat pipe in heat dissipation of the transformer is feasible. The model can be used to analyze the temperature characteristics of the transformer oil inside the transformer using the heat pipe for heat dissipation. The result in this paper provides the theoretic basis for design and reformation of the transformer.
