双绞线 电磁脉冲 传输线理论 抗干扰 Twisted-Wire Pair electromagnetic pulse transmission line theory anti-electromagnetic interference
摘要
双绞线是电子信息设备综合布线工程中最常用的一种线缆, 在高频电磁环境中, 双绞线将成为外界电磁信号的耦合对象, 对端接设备造成干扰甚至破坏作用。为研究双绞线的电磁脉冲效应, 基于分布参数传输线理论, 推导得到了双绞线在外界电磁脉冲激励下的耦合响应计算公式。结果表明, 在高频电磁环境中, 双绞线相对于平行线确有较强的抗干扰能力。研究方法和结论对于双绞线电磁脉冲响应的定量研究及抗干扰能力评估具有一定参考意义。
Abstract
Twisted-Wire Pair(TWP) is commonly used in the comprehensive wiring of electronics and information equipment. In high frequency electromagnetic environment, TWP may couple with external electromagnetic fields, which would interfere or destroy the connected equipment. In order to research the TWP’s electromagnetic pulse effect, based on transmission line theory, the calculation expressions of TWP response to external electromagnetic pulse are deduced. Results show that in high frequency electromagnetic environment, the TWP has stronger anti-electromagnetic interference ability. The research method and conclusion in this paper may be helpful to the quantification research of TWP’s electromagnetic pulse effect and the anti-electromagnetic interference ability assessment.
