三芯线BCI等效替代强场电磁辐射效应研究

Study on EM Radiation Effect of Three-Core Cable BCI Equivalent Replacing Strong Field

线缆是互联系统的重要组成部分,受到连续波强场电磁辐射时,线缆对终端设备的影响是不可忽略的。文中针对三芯线非线性互联系统,以终端设备响应相等作为等效的依据,证明了将等效注入激励源进行线性外推的方法,获取与强场辐射等效的注入激励源,进而可与强场电磁辐射实现等效,建立了等效注入激励源和辐射场强之间的线性外推模型,并进行了试验验证。

Cables are an important part of the interconnected system.When it is radiated by continuous wave field,the cables′influence on the terminal equipment cannot be ignored.In this paper,for the interconnection system of three-core cable connection is studied.The equivalent response of the terminal equipment is taken as the equivalent basis.It is proved that the method of linear extrapolation of the equivalent injection source can be equivalent to the high-level EM field.The linear extrapolation model between the equivalent injection excitation source and the radiation field strength is established,and it is tested by the experiment.
