摘　　要：建立了箔式绕组变压器场路耦合三维有限元模型,计算了变压器漏磁场分布及箔式绕组中的电流分布和交流损耗,得出了减小挤流效应和降低三相低压箔式绕组总损耗的方法。The 3D field-circuit coupled finite element model of transformer with foil wind- ing is established. The leakage magnetic field distribution of transformer and the current distribution and AC losses in foil winding are calculated. The methods to reduce crowd- ed flow effect and total losses of three-phase LV foil winding are presented.
