给出磁场的总体分布以及几个主要参数对磁场分布的影响

并且对其中两种结构的磁场进行实际测量

验证了该软件计算的准确性.

Abstract

A software for 3-D magnetic field calculation is designed by using single integration method. 3-D magnetic field generated by the current - carrying contacts is calculated numerically for three kinds of vacuum interrupters named cup - shaped axial magnetic structure

single pole （1/2 coil） structure

multi - pole axial magnetic structure. Based on the calculation

the distribution of magnetic field and the influ-ence of some key parameters are analyzed. Magnetic field in two of the above mentioned structures is measured and the result shows the calculation is accurate.
