本論文探討電力電纜相序排列方式對磁場的影響，與可行降低方法。本文以有限元素法電磁數值分析軟體FLUX3D，模擬現行台灣電力公司電纜涵洞及管路中電纜佈設模型，計算各擺設情形在周圍環境產生磁通密度分佈特性。建立電纜屏蔽架構後，模擬各種不同屏蔽板型式對磁場屏蔽效果之影響，與屏蔽材料的關係。經由模擬結果顯示，以提出之弧形屏蔽架構改善較佳。因此在屏蔽前必須充分掌握磁場分佈特性，運用適當的金屬形狀與材料做為屏蔽材料，將可獲得較佳的屏蔽效果。

In this thesis, it is to study the effects of space arrangement of power cables on the distribution of the magnetic field and the reduction methods. Then the finite-element-method software FLUX3D is used to set up the simulation models of power cables, including tunnel and tube structures used in the Taiwan Power Company. It is also to study the establishment of cable shielding structure, compare different frames of shielding models of cables, and compare the relationship between the shielding materials. From the results of simulation, it is shown that the arc type shielding model is the proper method. It is required to study and select suitable shielding materials and types before they are used to reduce magnetic field.
