摘要
漏泄同轴电缆结构看似简单,但其电容电感的精确计算并不容易。在前面的工作中我们给出了漏泄同轴电缆电容的精确计算方法。本文则给出漏泄同轴电缆电感的数值计算方法,并研究漏缆电感与漏缆外导体上缝隙角度之间的关系。在此基础上,结合已有的求解漏缆电容的数值方法,得到比较精确的漏泄同轴电缆的特性阻抗及其随缝隙角度变化的关系曲线。
Although the structure of the leaky coaxial cable seems simple, but the calculation of its capacitance and inductance is not so easy. In previous work, we proposed a method that can determine the capacitance of the leaky coaxial cable accurately. While in this paper, a method that can be used to calculate the inductance of the leaky coaxial cable accurately is presented. By using this method, the relationship between the inductance and the slot angle of the leaky coaxial cable can be easily studied. Combining this method with the previous numerical method proposed for capacitance calculation, the relationship between the characteristic impedance and the slot angle of the leaky coaxial cable is ready to be obtained.
