Treffer: 基于 PyAnsys 的干式变压器参数化仿真及分析.

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 1 150 mm to 1 200 mm. After optimization, the average temperature rise of the transformer is reduced from 69.22 K to 65.69 K. [ABSTRACT FROM AUTHOR]
