摘　　要：本文计算了导电圆环的内自感系数和外电感系数。对于通有低频电流的导电圆环,可近似认为电流在导电圆环的截面内均匀分布,且导电圆环半径远大于导电圆环截面半径。导电圆环的内自感系数可以根据直导线的内自感近似得出;而外电感系数可以根据导电圆环的空间辐射场计算得到。结果表明,最终得到的电感系数与实际工程经验相符。文中采用的方法为任意几何形状导电环的外电感系数的计算提供了有效参考。This paper explores the inductance coefficient of conducting circular ring, including internal self-induct- ance coefficient and external inductance coefficient. With consideration of low frequency current in conducting cir- cular ring, the current can be regarded as distributing uniformly in cross section of the ring. The internal self-in- ductance can be calculated according to the inductance of straight line conduct; and external inductance can be cal- culated by the electromagnetic radiation field of conducting circular ring. The results show that the inductance coefficient conforms very well to engineering experiences. Furthermore, the methods adopted in this paper can be a reference calculating the inductance coefficient of conducting ring of any shape.
