摘要
在模拟三维杂散损耗的第２１国际基准问题的基础上，提出并建立了以模拟大型变压器铁心低磁钢拉板为背景的三维涡流损耗模型。对该模型低磁钢板及线圈的磁通密度和涡流损耗进行了试验与计算分析，得到了一些有价值的试验和分析结果，为磁场计算和三维涡流损耗分析方法提供了验证手段。
On the basis of the international benchmark problem 21 on simulating 3D stray loss,the model on 3D eddy current loss is further presented and set in order to simulate core tie-plate made of non-magnetic steel in large transformers.Calculations and experiments are carried out on both magnetic flux density and eddy current loss of the non-magnetic steel plate and of the coil in this model.A number of useful results are acquired,and the means is given for validating magnetic field calculationsd and methods to analyse the 3D eddy current loss.
