摘要
为了得到复合材料对工频电场和工频磁场的屏蔽效能,根据屏蔽室法测量材料屏蔽效能的原理,分别提出了工频电场和工频磁场屏蔽效能测试系统的实验方案。并且,通过分析调整实验配置对实验结果的影响,提出改进方案,进一步完善了该测试系统。通过实验得到了屏蔽室内部和外部的电场分布情况,实验结果可以用于指导被保护电子器件在屏蔽体内安放位置和屏蔽体的设计。
In order to get the power frequency electric and magnetic shielding effectiveness of the composite materials,the experiment test methods are proposed respectively based on shielding enclosure method.By analyzing the experiment results when adjusting the test scheme,the experiment method is improved.The distributions of the electric field inside and outside of the shielding enclosure are obtained through the experiment.The experiment results can be used to determine the position of the electronic devices under protect in the shielding enclosure and guide the design of electromagnetic shielding enclosures.
