| 摘 要： | 文章针对工程中的电缆耦合问题，着重探讨了软辫线对屏蔽电缆耦合的影响。运用三导体传输线的理论分析了屏蔽层采用软辫线接地情况下的屏蔽电缆受邻近电缆耦合引起的串扰。在此基础上，仿真分析了因电缆间耦合作用到软辫线上而在屏蔽电缆上引起的串扰电压的幅频响应特征，结果表明：软辫线的存在一定程度上降低了屏蔽线的屏蔽效能。

| Abstract: | Aiming at the cable coupling phenomenon in engineering,the pigtail's effects on the shielded cables are discussed.By using the multiconductor transmission line method,the crosstalk inspired by nearby cable when earthing the pigtail of the shielding layer is analyzed.Based on this model,the amplitude-frequency characteristic of crosstalk voltages of the shielded cable with the pigtail are simulated.The simulation results show that the shielding efficiency of shielding layer could be depressed by the crosstal... |
