Based on finite element method (FEM), the vibration of power transformer windings caused by electrodynamicforce is analyzed.
利用有限元算法分析了三相电力变压器绕组各线匝在不同运行模式下电动力引起振动。

The current distribution under rated short-time tolerant current is tested, and so that the electrodynamicforce of each part in VGCB is calculated.
通过实验得到的额定短时耐受电流情况下电流分配，并以此为依据计算出VGCB各部分的受力情况。
