摘要
电缆被称为工业的“血管”和“神经”,广泛应用于设备互联。然而,传统电缆不具备分布式滤波功能,通常成为电磁兼容(EMC)性问题的主要耦合路径。滤波电缆,可以通过在绝缘电线上包裹采用柔性印刷电路板(FPCB)制造的特定缺陷导体层(DCL)、在绝缘圆柱体上包裹缺陷导体传输结构(DCTS),使其能够在轴向上实现分布式滤波功能。DCL或DCTS上具有特定蚀刻图案的导体起到等效的集总电路作用,被加到电缆电路中实现滤波功能,从而抑制干扰信号。采用微波网络分析技术可以高效地分析级联特性。国内外的研究现状和本团队的主要研究成果表明,滤波电缆能够有效实现分布式滤波功能,有望为复杂电磁环境防护提供一种新的解决方案。
Electrical cables are commonly referred to as the“blood vessels”and“nerves”of the industry,widely used in connecting electrical equipment.However,traditional cables do not possess distributed filtering capabilities,often becoming the primary pathway for electromagnetic compatibility(EMC)issues.Filtering cables employing specific defect conductor layers(DCL)wrapped around insulated electrical wires,and filter cable using defected conductor transmission structures(DCTS)wrapped around insulated cylinders,can achieve distributed filtering functionality along its axial direction.The DCL or DCTS with specific etched patterns act as equivalent lumped circuits that are integrated into the cable's circuit to create resonators,effectively suppressing interference signals.Furthermore,microwave network analysis techniques are employed to efficiently analyze the cascading characteristics.Both domestic and international research,along with our team’s significant research accomplishments,demonstrate that filtering cables and filter cables can effectively achieve distributed filtering capabilities,offering a new solution for safeguarding against complex electromagnetic environments.
