摘要
为了分析隧道中偶极子阻抗,对隧道中含有轴向漏泄电缆的偶极子激励场特性进行分析,采用电动势法推导出隧道中偶极子阻抗计算公式,给出了漏泄电缆和偶极子不同位置时偶极子相对电阻的数值结果,得出如下结论:随着偶极子距离隧道壁越近,则偶极子阻抗越大;轴向漏泄电缆对径向电偶极子和横向磁偶极子的阻抗产生一定的影响,对横向电偶极子和径向磁偶极子阻抗无影响。
To analyze the impedance of the dipole in tunnel, the electromagnetic fields of the diplole with braided coaxial cable in a circular tunnel are formulated and the expression for the impedance of the dipole is deduced by the method of EMF.The numerical results are given. The main conclusions are as follows： if the distance between the tunnel and the braided cable is closer, the resistance of the dipole is greater; the presence of the braided cable increases the resistance for both a transversely oriented electric dipole and a circumferentially oriented magnetic dipole, but don＇t affect the resistance for both a circumferentially oriented electric dipole and a transversely oriented magnetic dipole.
