变压器热点温度是评估变压器安全运行状况以及负荷能力的重要指标。在相同运行条件下变压器热点温度更低意味着变压器运行更安全，带载能力更强。变压器绕组结构和挡油板形成的油道结构会给变压器的热点温度带来一定影响。因此，需要构建变压器热点温度仿真模型，在建模时绘制不同结构的绕组和挡油板形成的油道来探究变压器内部结构对热点温度的影响。提出了一种基于SpaceClaim脚本语言的参数化建模的方法，将变压器相关结构和位置参数设置为可改变的变量，并通过运行脚本语言自动建模，从而实现变压器的快速建模。基于所提出的参数化建模方法绘制了不同绕组和挡油板结构的变压器模型，并通过有限体积法计算得到不同绕组和油道结构下的变压器热点温度分布。研究成果对指导变压器绕组和油道结构的设计具有重大意义。

The hot spot temperature of a transformer is a crucial indicator for assessing its safe operation and load capacity. Under the same operating conditions, a lower hot spot temperature signifies safer transformer operation and greater load-bearing capability. The winding structure of the transformer and the oil channel formed by the baffle plates can significantly influence the hot spot temperature. Therefore, it is necessary to establish a simulation model for the transformer's hot spot temperature. During modeling, oil channels formed by windings and baffle plates of different structures are drawn to investigate the impact of the transformer's internal structure on the hot spot temperature. A parametric modeling method based on SpaceClaim scripting language is proposed, where the transformer's relevant structural and positional parameters are set as variable inputs, and automatic modeling is achieved by running the script, enabling rapid transformer modeling. Based on the proposed parametric modeling method, transformer models with different winding and baffle plate structures are drawn, and the hot spot temperature distribution under various winding and oil channel structures is calculated using the finite volume method. The research findings are of great significance for guiding the design of transformer winding and oil duct structures.
