摘要
针对舰船工程中多种不同类型电缆复杂电磁耦合问题,重点研究屏蔽电缆和同轴电缆同时存在的情况下,屏蔽电缆电磁耦合的变化和影响。运用CST电缆工作室平台,结合工程实际,建立多电缆耦合参数化仿真三维模型,对单根接收电缆体系和2根不同种类接收电缆共存体系进行综合仿真和对比分析。研究结果表明,屏蔽电缆和同轴电缆作为接收电缆同时存在的情况下,屏蔽电缆中会出现新的电磁耦合,耦合电压的大小和频率与同轴电缆的相对位置有关;屏蔽电缆中旧有的耦合电压大小和频率受同轴电缆影响相对较小。
Aiming at the multi-cables coupling phenomenon in ship engineering, the electromagnetic coupling effects on the shielded cables are studied with shielded cable and coaxial cable existing at the same time. Based on the application of CST cable studio and engineering practice, the 3D simulation models of multi- cables are established and the system with single receiving cable and the system with two different kinds of receiving cables are simulated and analyzed, respectively. The results show that, when the shielded cable and coaxial cable exist at the same time, new electromagnetic coupling is found in the shielded cable and the magnitude and frequency of the coupling voltage are based on the relative location of the coaxial cable. On the other side, the original electromagnetic coupling in the shielded cable is almost not affected by the coaxial cable.
