摘要
绕组涡流损耗和漏磁通大小与导线尺寸有关,文章研究了铁心电抗器轴向漏磁通及径向漏磁通的分布情况,以及非均匀磁场下的绕组涡流损耗的计算方法。研究结果表明,随着电抗器容量的增大,涡流损耗系数会大幅度增加,导线宽度尺寸的增加也会使涡流损耗系数大幅度增加。
The magnitude of eddy current loss and'leakage flux of winding is related to the size of wire. In this paper, both axial and radial leakage flux distribution of iron core reactor and also the calculation method of winding's eddy current loss under uneven magnetic field are studied. The study results show that, with the increase of reactor's capacity, the eddy current loss coefficient will increase significantly, and the increase of wire' s width will also make considerable increase of the eddy current coefficient.
