Two-Dimensional Numerical Simulation of Temperature Field Distribution in Transformer Windings
摘要
With the rapid development of economy, modern power industry demands more and more transformer capacity. The increase of transformer capacity leads to the increase of heat production during operation and the corresponding increase of operating temperature. It is very important to analyze and calculate winding temperature rise for transformer product development and operation maintenance. In this paper, based on the heat generation and heat dissipation conditions of transformer windings, the finite element equations of temperature field and flow field are established by applying the principles of heat transfer and fluid mechanics, and the distribution of temperature field of windings is further obtained.
