摘要
以180MVA/220kV电力变压器负载损耗超标为例,利用漏磁场有限元软件对绕组涡流损耗进行了分析,讨论了变压器辐向漏磁对绕组涡流损耗的影响,提出了大型变压器磁势轴向布置原则。
Based on the example of overproof on-load loss in 180MVA/220kV power transformer, the eddy loss in windings is analyzed with the leakage flux finite element software. The influence of transformer radial leakage flux to the eddy loss in windings is discussed. A method to arrange axial magnetic potential of large transformer is presented.
