摘　　要：主要研究在大型变压器设计中如何通过加入磁屏蔽和电磁屏蔽结构来有效地减少杂散损耗,同时,为了简化结构并且还要切中杂散损耗的基本特征,建立了两组基于工程的基准屏蔽模型,这两组模型用来定量地研究通过加入屏蔽构件来有效地降低杂散损耗及模拟典型屏蔽的电磁行为,同时也可以验证使用的电磁分析方法的实用性和有效性。The paper aimed to how to effectively reduce the stray loss of the configuration by magnetic and/or electromagnetic shielding in larger transformer design. Two sets of engineering-oriented benchmark shielding models were built up in order to pinpoint the basic characteristics about the stray loss and simplified the configuration problem. The models were used to quantitatively investigate the effectiveness in reducing stray loss due to adding shielding configuration and simulate electromagnetic behavior of the typical shielding, accordingly the applicability and practicality of electromagnetic analysis methods were validated.
