    Abstract: Introduction was made to the theory of thermoelectric analogy and the process of heat production and heat dissipation of transformers. This paper expounded the traditional thermal circuit model of transformers, summarized the thermal circuit model of transformers and the improvement of parameters and analyzed the advantages and disadvantages of different thermal circuit models, concluding and expecting the application scenarios. This paper proposes that some problems need to be paid attention to in the follow-up transformers’ thermal circuit model study.
    Key words: transformer; thermal circuit model; hot spot temperature; non-linear thermal resistance; heat capacity; thermoelectric analogy
