电子机柜电磁辐射源的简化建模

摘要

根据电基本振子辐射原理,结合电磁兼容标准检测数据,运用FEKO软件建立了三维对称振子模型代替电子机柜的电磁辐射源,通过计算并与理论情况比较验证了该模型的合理性.可以利用该模型预测舱室内部场强分布,能为各种重要舱室内设备的EMC优化布置设计提供指导.%Based on the radiation theory of electric dipole and the test data of EMC standards, the equivalent model of the radiation source of electronic cabinet is carried out using FEKO. And the model is testified by calculating the fields in the compartment. This model can be used for predicting the fields in the compartment, which can provide guidelines for the optimization arrangement of equipments in various important compartments.
