摘要
文章主要阐述了IEC 61000-4-6:2023相对于GB/T 17626.6-2017的变更及新增内容,从选择注入法的规则、饱和度检查程序、试验布置和多待测设备试验要求等方面,对两标准之间的技术差异进行了分析。同时,对标准实施过程中常见的问题进行了解读,包括耦合/去耦网络、电流钳和电磁钳的使用以及直接注入法和大型EUT的试验布置等,可以为实验室实施和使用IEC 61000-4-6:2023提供技术指导,为GB/T 17626.6-2017后续的修订提供参考。
This paper mainly describes the changes and additions of the IEC 61000-4-6:2023 compared with the GB/T 17626.6-2017,and analyzes the technical differences between the two standards in terms of the rules of the selective injection method,saturation checking procedure,test layout,multi-EUT test requirements and so on.At the same time,the problems that are likely to occur during the implementation of the standard are interpreted,including the use of CDN,current clamp and electromagnetic clamp,as well as the test layout of the direct injection method and large-scale EUT,etc.This can provide technical guidance for laboratories in the implementation and use of the IEC 61000-4-6:2023,and provide a reference for the subsequent revision of the GB/T 17626.6-2017.
