Abstract
An axial magnetic field vacuum interrupter includes electrode stems each having a member made of a highly conductive material, such as high conductivity copper. The conducting member has a plurality of angularly spaced, longitudinally extending slots that can be left open or filled with a material of lower conductivity. The member can by surrounded by an annulus of a lower conductivity material for added structural support. An axial core fabricated of a lower conductivity material can also be used. The slots and the lower conductivity materials reduce the production of eddy currents in the stems by the axial magnetic field, and thereby serve to reduce the phase delay between the field and the current and improve the quality of the field in the intercontact region.
