摘要
目前变压器热点温度研究主要分为两大方向:直接测量法和间接计算法。该文对两种研究方法进行分类介绍,对比各方法的适应性和局限性。最后,通过各方法优缺点对比,提出每种方法都有各自适用的场合,应该根据情况灵活选择,也可以考虑多种方法相互配合使用的观点。
At present, the research of transformer hot spot temperature can be divided into two main directions: direct measurement and indirect calculation. In this paper, two kinds of research methods are classified and compared, and the adaptability and limitations of each method are compared. Finally, by comparing the advantages and disadvantages of each method, it is pointed out that each method has its own applicable occasions, should be flexibly selected according to the situation, and can also consider the viewpoint that a variety of methods can be used together.
