摘要
介绍用线性边界元法计算对称多芯屏蔽电缆电容的基本原理和求解过程.2个工程实例的计算结果表明:用线性边界元法计算对称多芯屏蔽电缆,不仅具有较高的精度,而且可很方便应用于各类变形多芯屏蔽电缆的工程计算;给出了两种多芯屏蔽电缆不同位置放置时各芯线间的耦合电容随变形程度变化的关系曲线,获得了两种电缆合适敷设位置.
The linear boundary element method(LBEM) is presented as a approach for the analysis and design of various symmetry shielded multiconductor cables.Two representative computational examples,the deformed shielded balanced pair transmission line and the deformed shielded cable consisting of 3 cylindrical conductors,are given to validate the theory.To demonstrate the accuracy and flexibility of the LBEM,the influence of the deformation degree of the last two cables on the results are discussed,and the curves of the coupling capacitance that the influence of the deformation degree of the latter two cables at different location and the suitable location for laying of cables are given.
