【摘要】：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。
[Abstract]:A method for calculating partial inductance of open circuit conductors is presented. The inductance of conductors is closely related to the energy of the magnetic field, but the existing partial inductance theory is inconsistent with the energy method in the calculation of open circuit conductors. The method proposed in this paper takes into account the effect of the displacement current generated by charge accumulation at both ends of the conductor on the basis of the existing partial inductance theory. It is proved by analytical analysis that the displacement current part will significantly affect the calculation of vector magnetic potential A and then affect the calculation results of some inductors. Numerical simulation shows that the inductance obtained by this method is in good agreement with the energy method, but the existing methods have obvious deviation. At the same time, the proposed method can also be used to calculate the inductance of the circuit conductor, and the effect of the displacement current will cancel each other at the junction of the conductor, so it is consistent with the results of the existing methods.
