摘要
提出用多极理论分析工频情况下的载流导体涡流场问题。从稳态情况下的Maxwell方程出发,推导出用多极理论计算载流导体涡流场问题的计算公式和相应的约束方程,并给出其计算实施过程。实例计算结果表明:多极理论的计算结果与实验值和其他数值方法的计算结果完全一致。
A new approach,the multipole theory(MT) method,is presented for determining power frequency current distribution in current carrying conductors.From the Maxwell′s equation of the steady state case,the field function is formulated by a set of MT series solution,and the eddy field formula is derived.By calculating and analyzing two engineering problems,it is shown that the MT method is an effective approach for determining power frequency current distribution in current carrying conductors.
