Method for analyzing the inner temperature field and flow field in power transformers

摘要

A method for analyzing the inner temperature field and flow field in power transformers uses an Icepak application™ to simulate at least one value of the component the power transformer. Steps: inputting at least one first parameter value of the component of the power transformer, and inputting a calculated heat flux value of the component of the power transformer; the parameter such as material characteristics and loading conditions of the power transformer, length, width, height dimensions of the case of the power transformer and so on. Furthermore, generating a model value of a power transformer; establishing grid values of the power transformer model; calculating the heat transfer data of temperature field and flow field; and outputting the results in graphs so as to obtain an efficient, easily improved, and optimum internal components design in power transformers based on the simulation data to gain the best power transformer heat distributing design.
