摘要

变压器热点温度是直接影响变压器绝缘老化速度及决定变压器运行状态的重要因素之一。文中综述了近年来国内外变压器热点温度研究方法的发展历史及现状。文中主要对基于测温系统的热点温度监测

基于经验公式、热路模型或数值计算方法的热点温度计算及基于人工智能学习算法的热点温度预测三大类方法进行了归纳总结

对比了各类方法优缺点

并论述了三类方法今后的研究、发展方向。

Abstract

Hot-spot temperature is an important factor which immediately affects aging degree of insulation insidetransformer

and determines its operation condition. The development and present situation about research methodsof hot-spot temperature inside transformer in home and abroad are reviewed in the paper. The research methods of hot-spot temperature can be divided into temperature monitoring based on temperature measurement system

tempera-ture calculation based on empirical formula

thermal circuit model or numerical calculation method

and tempera-ture prediction based on intelligent learning algorithm

and the merits and demerits of above methods are discussed.At last

the research tendency of these three methods is discussed.
