| 摘 要： | 以农用隐蔽式信号电缆的开孔屏蔽壳体为研究对象,应用线性边界元法计算了屏蔽体上开有不同对称/非对称孔型时对屏蔽效能的影响。根据工程实例计算表明:对于双芯屏蔽电缆,当孔深较浅时屏蔽电缆的耦合电容影响不大,随着孔洞深度的增加,对称/非对称劈形孔耦合电容变化幅度最小;而不同形状孔洞的宽窄对耦合电容影响不太明显。 |

| Abstract: | With the rural concealed communication cable as the study object, the shielding effectiveness of different slot shapes was analyzed by using LBEM (linear boundary element method). The engineering example results showed that for two-core shielded cable, the coupling capacitance of trapezoid slots (asymmetric and symmetric) changed the most, followed by rectangular slots (asymmetric and symmetric), and the changes of wedge slots were the smallest, but the change tendencies were consistent. In addition, with the increase of slot width of different slots, the coupling capacitance of tow-cored shielded cable showed small change. |
