摘要:
针对现有变电站穿墙套管固定法兰存在的涡流损耗大、温升明显的问题。对这种结构进行了优化,提出了在传统结构上开槽和设置永磁体整列的方案。对比分析利用该方法的改进结构和传统结构二者相同位置的损耗,得出改进结构能有效抑制其内部的涡流损耗。进而研究改进结构上槽体数量和设置不同的永磁体阵列对其内部磁感应强度的抑制效果,最终得出槽体为4并且设置永磁体阵列的法兰结构为最优方案。
Abstract:
According to the problem of large eddy current loss and obvious temperature rise in fixed flange of wall casing in substation, in this paper, the structure is optimized, and the scheme of slotted and integrated permanent magnet in the traditional structure is put forward. By comparing and analyzing the loss in the same position between the improved structure and the traditional structure, it is concluded that the improved structure can effectively suppress the eddy current loss inside the structure. Furthermore, the effect of improving the number of slots and setting different permanent magnets array on the internal magnetic induction intensity is studied. Finally, the flange structure with slot body 4 and permanent magnet array is obtained as the optimal scheme.
