摘　　要：针对仿真模拟过程中传统人工手动建模和参数输入方式效率低、易出错、重复工作多的特点,本文提出了一个基于PyAnsys对干式变压器传热性能进行参数化仿真的仿真流程,该流程采用了Python和Ansys中的SpaceClaim与Fluent功能组件相结合的方式,通过调用建模以及仿真脚本可以快速、高效地进行CFD仿真;与传统手动进行CFD仿真的方式相比,可以节省70%的时间并准确计算变压器的温升情况。基于实验数据对仿真平台的精度进行了验证,并基于验证后的仿真平台对某干式变压器进行了优化,优化后的干式变压器气道宽度由原来的16 mm改为18 mm,绕组长度由1 150 mm改为1 200 mm,优化后的变压器平均温升由原来的69.22 K降低到65.69 K。Aiming at the characteristics of low efficiency,error-prone and repetitive work of traditional manual modeling and parameter input in the simulation process,a simulation process based on PyAnsys for parametric simulation of heat transfer performance of dry transformer is proposed in this paper.This process uses the combination of SpaceClaim and Fluent functional components in Python and Ansys,and can conduct CFD simulation quickly and efficiently by invoking modeling and simulation scripts.Compared with the traditional manual CFD simulation method,it can save 70%time and accurately calculate the temperature rise of the transformer.Based on the experimental data,the accuracy of the simulation platform was verified,and a dry-type transformer was optimized based on the verified simulation platform.The optimized dry-type transformer airway width was changed from 16mm to 18mm,and the winding length was changed from 1150 mm to 1200 mm.After optimization,the average temperature rise of the transformer is reduced from 69.22 K to 65.69 K.
