【摘要】 针对埋地线缆面临的电磁干扰问题,基于细导线时域有限差分(FDTD)方法,开展了埋地线缆高功率微波(HPM)耦合分析。首先,基于细导线FDTD算法,对沿水平方向铺设的埋地线缆进行建模。然后,计算了当HPM垂直、水平辐照线缆时,线缆不同位置、半径、埋地深度等参数变化情况下线缆的耦合结果。最后,分析了埋地线缆不同参数对终端耦合电流的影响,为埋地线缆的电磁防护设计提供了参考。更多还原

【Abstract】 To study the electromagnetic interference problem of buried cable,the finite-difference time-domain(FDTD) method of thin wire is proposed to analyze the HPM radiation of buried cable.In this paper,based on FDTD method of thin wire which is smaller than FDTD grid size,the buried cable is modeled,and the HPM radiation is simulated by plane wave.The coupling effect of HPM on buried cable is studied and analyzed from three aspects of different position,radius and buried depth of cable.The influence of the radius and depth of the buried cable on the coupling current is obtained by simulation analysis,which provides the basis for the electromagnetic protection design of the buried cable.更多还原
