| 摘 要： | 依据趋肤效应对导线横截面上电流密度分布影响的公式,推导出了传输导线等效电阻随频率变化的关系式,并将等效电阻随频率变化的计算值与文献中[1]已有的实验测试值进行了比较,发现频率越大,误差越大.在考虑了导线自身电感值的条件下进行了实验测试,其结果与理论计算值基本一致,证实了在频率较高的情况下,传输导线的自感对实验结果的影响不能忽略.

| Abstract: | The functional relationship between the equivalent resistance of transmission line and the frequency of current in it is obtained according to the effect of skin effect on the distribution of current density in the cross section of transmission line. It is found that there is difference between the equivalent resistance calculated according to the functional relationship and the experimental data in literature , and the greater the frequency, the greater the difference. But after the self inductance of the transmission line is taken into account in the experimental data, the difference is little. This shows that the effect of the self inductance on the equivalent resistance can not be neglected when the frequency is greater. |
