Abstract

Toroidal transformers are designed using a circular core instead of the traditional laminated rectangular core, which reduces inductance losses and increases efficiency. The primary goal of this study is to understand the cooling mechanisms involved in electrical transformers, which are critical components in power systems. Steady electromagnetic, fluid flow and temperature equations are simultaneously solved (direct method) using the finite elements method FEM of a shielded toroidal transformer. The paper focuses on creating a direct-coupled model (DCM) to understand the processes involved in electrical transformers cooling, using Magneto-AeroDynamic (MAD) models. The nonlinear models developed will be implemented and validated in this parametric study for different inlet velocities and the number of outlet. Transformers generate heat during operation, and it’s important to control the temperature to prevent overheating and ensure reliable operation.
环形变压器尺寸的磁热和空气动力学研究
环形变压器在设计时使用了圆形铁芯,而不是传统的层叠矩形铁芯,从而减少了电感损耗,提高了效率。本研究的主要目标是了解电力变压器的冷却机制,因为变压器是电力系统中的关键部件。使用有限元方法 FEM 同时求解了屏蔽环形变压器的稳定电磁、流体流动和温度方程(直接法)。论文的重点是创建一个直接耦合模型(DCM),利用磁空气动力学(MAD)模型了解变压器冷却过程。所开发的非线性模型将在本参数研究中针对不同的入口速度和出口数量进行实施和验证。变压器在运行过程中会产生热量,因此控制温度以防止过热并确保可靠运行非常重要。
