摘要

本文以简单等效电路的形式建立了电力变压器的热模型。建立了计算顶油温度和热点温度的模型。模型参数由制造商试验数据和有限元电磁分析得到。将模型结果与安装光纤探头的250mva, 230plusmn8times1.5%/118/ 21kv ONAF变压器的实测数据进行了比较，并在2.1 pu的短时间负载周期下进行了测试。并将计算结果与IEEE第7条款的常规方程进行了比较

Thermal model for power transformers dynamic loading

This paper presents a thermal model of a power transformer in the form of simple equivalent circuit. The model is established to calculate the top oil and hot spot temperatures. The model parameters are obtained from manufacturer test data and an electromagnetic analysis using finite element method (FEM). The model results are compared with measured data obtained from 250 MVA, 230plusmn8times1.5%/118/21 kV ONAF transformer equipped with fiber optic probes and tested according to a load cycle comprising a short time load up to 2.1 pu. The results are additionally compared with the conventional equations of the IEEE clause 7
