电线电缆在电磁兼容方面的设计要点

Design Key of the Wires and Cable in the Aspect of EMC

本文从电磁兼容技术的根本任务和研究方向出发,进行归纳整理了电线电缆在电磁兼容方面的研究方向,包括不同屏蔽形式,传输模型,电线电缆接地及试验等。讨论了与电线电缆相关的屏蔽、滤波、接地抑制电磁干扰的三大技术,最后指出三大技术也是相互补充和相互关联的,没有包罗万象的统一方法,非常有必要从不同方面进行研究。

This text mainly sums up wires and cables research in the aspect of EMC from the basic task and research direction of EMC technology,it concludes different screen,transmission model,earthing and test of the wires and cables etc. The text discusses the screen、filter、earthing technologies of the wires and cables for restraining electromagnetic interference. Finally three great technologies are complementary and associated each other. It is necessary to research it from the different aspects.
