摘要
提出矿用监控分站电磁辐射干扰仿真的必要性,介绍了仿真软件HFSS及其电磁场分析的数值计算方法——有限元法。利用HFSS建立起分站模型和电磁场环境,通过仿真,分别预测出不同频率辐射场下外壳的电磁屏蔽效能,并模拟得出线缆耦合所造成的干扰,对产品早期设计起到参考作用。
The paper present that it is necessary to simulate for resistance to electromagnetic interference of mine-used substation, simulation software HFSS and numerical methods for electromagnetic field analysis--FEM are introduced. Substation model and the electromagnetic environment are established by HFSS, the electromagnetic shielding effectiveness under different frequencies of electromagnetic radiation are predicted through simulation, and interference caused by the cable coupling is obtained, it provides a reference for the early design of product.
