| 摘 要： | 针对工程中的电缆耦合问题,着重探讨了屏蔽电缆的电磁耦合影响。运用三导体传输线的理论建立屏蔽电缆电磁耦合的等效电路模型,并分析了相关的感性耦合和容性耦合。在此基础上,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特征进行了仿真分析,结果表明,将屏蔽层任一端接地都能消除容性耦合;只有将屏蔽层两端都接地,才会影响到感性耦合。

| Abstract: | Aiming at the cable coupling phenomenon in engineering,the electromagnetic coupling effects on the shielded cables are discussed.It formulates an equivalent circuit system in which the coupling effects on shielded cable are analyzed with the multiconductor transmission line method.And the inductive coupling and capacitive coupling are analyzed.Based on this model,the shielded cable's amplitude-frequency response of inductive voltage inspired by near cable is simulated,which shows that the capacitive couplin... |
