摘　　要：　介绍用多极理论计算多芯屏蔽电缆电容的基本原理和求解过程,给出多芯屏蔽电缆电容与多极理论级数项系数之间的关系。3个工程实例的计算结果表明:用多极理论计算多芯屏蔽电缆电容,不仅具有较高的计算精度,而且可以很方便地应用于各类复杂截面多芯屏蔽电缆的工程设计与计算,多极理论是分析多芯屏蔽电缆电容的一种有效方法。The multipole theory (MT) method was presented as a new approach for the analysis and design of various shielded multiconductor cables. The solution of boundary-value problem associated with the shielded multiconductor cable was represented by the generalized MT formula, and the procedure to obtain the capacitance of shielded multiconductor cable was described. Three representative computational examples, the deformed coaxial cable, the shielded balanced-pair transmission line and the cable consisting of 10 cylindrical conductors, were given to validate the theory, and to demonstrate the accuracy and flexibility of the MT method.
