| 现有变压器设计方法没有对谐波下绕组结构进行精确设计，为此提出了一种考虑集肤效应与邻近效应的静电除尘变压器绕组谐波损耗优化设计方法。利用Helmholtz方程对交流谐波下铜箔、矩形及圆形导体绕组的损耗进行了分析及优化，并考虑了磁芯窗口参数的影响，对比了各种优化方法的优缺点及应用场合。样机实验结果表明，该方法可以准确给出谐波损耗最小时的优化结构，适用于大功率定制变压器的设计。 |

| Abstract: |
| Because the transformer winding structure under harmonics cannot be accurately designed using existing transformer design methods, a winding design method of the electrostatic precipitation transformer is proposed based on the skin and proximity effects. On the basis of the Helmholtz equation, AC harmonic losses of copper foil, rectangle and circular conductor windings are analyzed and optimized. The impact of core window parameters is considered. In addition, different kinds of optimization methods are compared in terms of their respective merits, demerits and applications. The experimental results based on a prototype verify that the winding optimization method can provide the optimal structure with the minimum harmonic loss and is suitable for high power custom-made transformers. |
