摘要
针对工程中的电缆耦合问题,着重探讨了电缆耦合预测的计算方法。运用多导体传输线的理论为均匀/非均匀介质中的电缆耦合建立相应的等效电路模型,并采用计算电磁学中的有限元数值计算方法获取该电路模型里的电容、电感参数。在此基础上,借助软件工具对三条电缆间的耦合情况进行仿真计算,分析信号频率、电缆长度对电缆耦合的影响,以此作为电缆敷设的指导依据,从而实现电缆耦合预测。
In view of the cable coupling problem in project,this paper discusses a transmission line approach for the computation of cable coupling prediction.It formulates an equivalent circuit system in which the electromagnetic coupling between cables is analyzed with the multiconductor transmission line model.And the method of finite element is used to compute the values of capacitance and inductance matrices in the circuit.The simulation in the scenario of three parallel cable coupling describes the frequency res...
