摘要: 本文对空心螺旋线圈的分布电容及阻抗特性进行了理论和实验研究，测量了螺旋线圈分布电容的频率特性及其与线圈匝数和绕线方式的依赖关系，以及螺旋线圈阻抗随匝数的变化规律。观察到当线圈匝数大于10时，分布电容的数值与匝数和绕线方式几近无关。通过测量线圈的(器件型)磁电容效应发现，线圈的分布电容与线圈材质有关，其机理可从趋肤效应得到解释。从线圈的等效电路出发，结合趋肤效应推出分布电容及阻抗的表达式。分析显示，线圈的分布电容主要来源于匝间电容。
Abstract: The characteristics of distributed capacitance and impedance of hollow coils are studied theoretically and experimentally. The frequency characteristic, the number of turns and winding mode dependent capacitor of the coil, and the impedance versus number of turns of hollow coils have been measured, respectively. The distributed capacitance has been observed almost irrelevant to the number of turns and the winding ways of the coils when the number of turns is greater than 10. By measuring the magneto-capacitance effect of spiral coil, it was found that the distributed capacitance of coil relates to the coil material, suggesting the influence of skin effect. From the coil equivalent circuit, combining with the skin effect, an approximate formula of distributed capacitance and impedance have been worked out. Analysis showed that the distributed capacitance of coil mainly originates from line capacitance and the capacitance between turns.
