摘要
本文由磁矢量位出发,导出具有任意形状截面的长导体磁场计算公式。然后对有重要工程意义的多边形截面和矩形截面汇流排的磁场分析与计算做了详细的说明,并推导出相应的计算公式。经由矩形导电母线验证了所推导公式的正确性。
In this paper, the calculating formulas of magnetic field for long current carrying conductor with any form of cross-section are deduced with the help of magnetic vector potential. The analysing and calculating of magnetic field of multilateral and right angle cross-section, which act important role in electric power engineering, are illustrated detailedly and the calculating formulas are also given. The rightness of the deduced calculating formulas are verified through the magnetic field calculating of right angle bus bar.
