ABSTRACT:
A vacuum interrupter includes a pair of separable electrode assemblies within a vacuum envelope, each electrode assembly including a contact confronting the contact of the other electrode assembly and an electrode coil assembly located behind the contact for generating a magnetic field in a region between the contacts. The electrode coil assembly, which is energized by an a.c. current in the interrupter, includes a generally annular-shaped member having a plurality of slots extending radially between a peripheral surface and an interior surface, the slots defining a substantially circumferential current path. The slots include an axially extending slot and a circumferentially extending slot that define a coil. The electrode coil member is connected in series between a terminal post and the contact of the electrode assembly. The electrode coil assembly also can include a tubular support for the contact.
