摘要
使用软磁薄膜材料对单路电力电缆和回路电力电缆进行屏蔽,测量屏蔽前后周围空间的磁场强度。结果表明,软磁薄膜材料作为单路电力电缆的屏蔽层并不具备磁屏蔽效果,而其在回路电力电缆中使用则具有明显的磁屏蔽效果。之后通过仿真计算的方法对实验结果进行验证,并结合仿真和实验结果进行理论分析。
The use of soft magnetic thin film shielding on both the single power cable and loop power cable by measuring me magnetic field intensity of the surrounding space before and after shielding with thin film material was studied. Results show that the layer of soft magnetic thin film material on single power cable doesn＇t have magnetic shielding effect, but its use in the loop power cable has obvious effect of magnetic shielding. The experimental results are verified well by the simulation method, and the theoretical analysis is carried out by combining the simulation and experimental results.
