摘　　要：深海环境为散热提供了有利条件,因此水下机器人装配的环形变压器可以具备更高的功率密度和损耗。为研究环形变压器在水下环境的温升情况,结合热路理论及其散热结构,建立相应的稳态热路模型。以14.3 kVA的单相中频环形变压器为研究对象,将热路模型计算所得结果与Fluent有限元软件仿真和温升试验结果进行比较。结果表明:热路模型计算结果与二者之间的误差在6%以内,同时与有限元仿真相比,使用热路模型计算的分析过程更为简单。所提出的热路模型适用于深海环形变压器的温升分析。The deep-sea environment provides favorable conditions for heat dissipation,so the toroidal transformer equipped within the underwater robot can have higher power density and loss.In order to study the temperature rise of the toroidal transformer in the underwater environment,combined with the thermal circuit theory and its heat dissipation structure,a corresponding steady-state thermal circuit model was established.Taking the 14.3 kVA single-phase intermediate frequency toroidal transformer as the research object,the calculation results of the thermal circuit model were compared with the results of the Fluent finite element software simulation and temperature rise test.The results show that the error between the calculation result of the thermal circuit model and the latter two occasions is within 6%,and compared with the finite element simulation,the analysis process of the calculation using the thermal circuit model is simpler.The proposed thermal circuit model is suitable for the temperature rise analysis of deep-sea toroidal transformers.
