摘要

运用ANSYS有限元软件对某型号电力变压器的电磁场分布及金属结构件的功率损耗进行了仿真模拟

分析讨论了油箱侧壁屏蔽板高度以及绕组端部处屏蔽条的引入对变压器各部件损耗的影响。结果表明

屏蔽条的引入既减少了进入夹件中的漏磁通密度

同时也降低了线圈端部处的横向磁通密度

能极大地降低夹件和油箱中的杂散损耗。合适高度的箱壁屏蔽板能降低部分结构件的涡流损耗。这些结果可以为变压器的合理设计提供参考依据。

Abstract

The finite element software ANSYS is adopted to simulate the electromagnetic field of a transformer and the power losses of its structural parts. The effects of the height of shielding plate on tank wall and the additional shielding rods located at winding ends on the stray losses of steel structural parts are analyzed. The results show that the introduction of the shielding rods can reduce both the leakage magnetic field in the clamps and the transverse magnetic field at coil ends

and can also significantly reduce the stray losses in the clamp and tank. The shielding plate with appropriate height can reduce the eddy current loss of some structural parts. This study may provide a reference for rational design of transformer.
