AXIAL MAGNETIC FIELD VACUUM FAULT INTERRUPTER

摘要

An electrode assembly is disclosed for use in a vacuum interrupter. The electrode assembly has a substantially cylindrical contact support structure having a first resistivity, and a substantially ring-shaped structure disposed in contact with the contact support structure and having a second resistivity higher than the first resistivity. An electrical contact is disposed in contact with the ring-shaped structure such that the ring-shaped structure is between the contact support structure and the electrical contact. Also disclosed is a vacuum interrupter with a first electrode assembly, and a second electrode assembly on a common longitudinal axis with respect to the first electrode assembly and movable along the common longitudinal axis, wherein the first and/or second electrode assembly is as described above
