摘　　要：本又对利用绝缘避雷线抽能的问题进行了研究,首次提出调谐法抽能,论述了原理、方法以及供理论计算用的抽能系统等值电路。研制了5kVA的调谐变压器抽能装置,进行了调谐和抽能试验。试验结果表明,应用调谐法和使用本装置能达到先进的抽能水平。文中用非线性电感的描述函数通过逼近法比较准确地确定了临界阻尼电阻。On the basis of studying the problem of using insulated conductor against lightning obtaining power,the paper puts forward the tuning method the first time, introduces conception, way and an obtainable power system equivalent circuit for theory comput- ing,Furthermore, the paper describes a 5 kVA tuning transformer obtaining power equi- pment invented by the author, and have done tuning and obtaining power experiments. The result of the experiments shows that it can reach advanced level of obtaining power by tuning method and the equipment.Besides,the paper gives accurate critical values of R by using the describing function of the nonlinear inductance and search method.
