摘要
本文详细地计算了圆环形三相电流线圈的磁场分布，推导出线圈的自感、互感和等效电感的计算公式，对线圈尺寸及线圈间尺寸对电感的影响进行了分析讨论，得出一些对工程实践有用的计算公式和一些建设性意见。
In the paper,we calculated accurately the distribution of magnetic field due tocurrents passing through three phase solenoids,deduced the self conducinfluence to the conductance owing to the measurement of coils and the meastirement among coils,and supported manyformulae and opinions which are uselful for the engineering practice.
