针对工程中的电缆耦合问题,采用多导体传输线方法。构建了多层屏蔽电缆电磁耦合的等效电路模型,分析了相关的感性耦合和容性耦合影响效果,并对某屏蔽电缆受邻近电缆耦合引起的串扰电压的幅频响应进行了仿真。结果表明,采取双层屏蔽较单层屏蔽能较大程度地减小耦合干扰。
Aiming at the problem of cable coupling in engineering, multi-conductor transmission line method is adopted. The equivalent circuit model of multi-layer shielded cable was established. The effect of inductive coupling and capacitive coupling was analyzed. The amplitude-frequency response of crosstalk voltage caused by the coupling of adjacent shielded cable was simulated. The results show that the use of double shielding than single shielding can greatly reduce the coupling interference.
