摘要
基于矩量法理论,提出了一种分析带两端接地电缆的接地网接地性能的频域方法。该方法以各段导体的轴向电流以及流过电缆屏蔽层的电流为待求变量,不但待求量比较少,而且可以考虑接地导体之间以及接地导体和电缆屏蔽层或铠装之间的互感影响。使用该文方法,对一大型接地网与接于其上的一根电缆之间的相互影响进行了分析。
In this paper, a numerical method that can beused to analyze the grounding grid with two-end groundedcables is presented. The currents flowing through the cables’sheaths and through the grid segments are used as unknownvariables so that the mutual inductances can be considered andthe number of unknown variables is small. The influencebetween a large grounding grid made of steel and a two-endgrounded coaxial shielded cable is analyzed.
