Finite element three-dimensional modeling of cooling system for a class of strong oil circulating air-cooled transformer

Transformers, cooling systems, finite element, temperature field distribution, three-dimensional modeling

The temperature rise of transformer cooling system is an important reference to measure the thermal characteristics of transformer and its numerical simulation calculation can analyze and evaluate the temperature field distribution of cooling system as a whole. On the basis of the analysis and structure division of the cooling system of the strong oil circulating air-cooled transformer, this paper fully considers the compression rate of the oil channel cushion block, and completes the strong oil air-cooled radiator system, the inlet pipeline distribution system in the whole cooling oil flow system of the strong oil circulating air-cooled transformer in an innovative way, Finite element three-dimensional modeling of three departments in the winding system of the main sub-guide oilfield.
