摘　　要：利用MagNet软件,对铁心夹件、油箱和电屏蔽采用表面阻抗边界条件,计算了铁心夹件、拉板、油箱及低压引线升高座等结构件损耗,分析了夹件宽度、油箱磁分路和引线升高座屏蔽对损耗的影响。Based on boundary conditions of surface impedances for core clamps, tank and electric shields, the losses of core clamps, flitch plate, tank and LV lead ascending are calculated with MagNet software. The influences of clamp width, tank magnetic shunt and lead flange to losses are analyzed.

关 键 词：杂散损耗 有限元 表面阻抗 磁分路
