提出了一种针对开路导体的部分电感计算方法.导体的电感值和磁场能量密切相关,而现有部分电感理论在计算开路导体时,会得到与能量法不一致的结果.该文所提方法在现有的部分电感理论基础上,考虑了导体两端电荷积累产生的位移电流所带来的影响.解析分析证明位移电流部分会显著影响矢量磁位A的计算,进而影响部分电感的计算结果.数值仿真表明此方法获取的电感值和能量法完全吻合,而现有方法则有明显偏差.同时,所提方法也可以用于回路导体的电感计算,位移电流的影响会在导体连接处相互抵消,因此与现有方法结果一致.“,”This paper was specific to conductor segments not forming a closed loop.Taking the displacement current generated by charge accumulation into consideration,this paper present a partial inductance method for conductor segments.Considering charges accumulating at both ends of conductor segment and displacement current,the model obeys ACL (Ampere's Circuital Law) and obtains an accordant result of this method and energy method.This paper firstly derives that A generated by displacement current of charges accumulation is considerable.Then partial inductance calculation is given by superposition of effect of conduction current and displacement current.Numerical experiment and theoretical proving indicate the accordance between the proposed method and the energy method,whereas existing method may give over 50％ larger result for a short cylindrical conductor.In addition,this method can also be applied in a closed loop,because the effect of displacement current can be compensated.
