Abstract :
Different heat effects will arise due to failures of oil-immersed transformer, thus lead to abnormal temperature rise. Based on the theoretical analysis on temperature-field of transformer, the solid model of large oil immersed transformer was built using SolidWorks, and the temperature-fields are analyzed in this paper. Three-dimensional temperature-fields distribution of transformer are obtained in three typical conditions, which contributes to the state monitor and failure diagnose of transformer.
