The axial magnetic field distribution on center surface of contact gap and contact piece are calculated when the current is at peak . it can be found that the intensity of axial magnetic field and radial magnetic field uniformity are strengthened after the iron core is put into , this helps to improve the stability of the vacuum arc 计算了电流峰值时触头间隙中心平面和触头片上的纵向磁场分布,可以看出加入铁芯后纵向磁场强度和径向磁场均匀性增强,这有利于提高真空电弧的稳定性。
The calculation to the eddy current on the contact surface and axial magnetic field of contact surface and center surface of contact gap are carried out while the current is at zero . after the iron core of ring type is put in , the eddy current on the contact surface will be increased , the axial magnetic field that the eddy current creates will be also increased 对电流过零时触头表面的涡流和触头表面及触头间隙中心平面上的纵向磁场进行了计算,加入圆环型铁芯后触头表面的涡流增大,涡流产生的纵向磁场增大,在铁芯中开槽后涡流的平均水平降低,纵向磁场平均值降低。
