摘　　要：本文中作者通过总结大量产品的磁屏蔽制造经验,结合有限元分析,提出一种优化的油箱磁屏蔽结构。并对一台大型电力变压器优化前后的损耗实测对比,验证了新结构的有效性。According to summarization of manufacturing experience of magnetic shielding,combined with finite element analysis, a optimized structure of tank magnetic shielding is presented. The effectiveness of the structure is verified by the comparision of the loss value before and after the optimization.
