An electrode assembly for a circuit breaker is provided. The electrode assembly includes a conductive assembly and a heat transfer assembly. The conductive assembly includes a stem portion and a contact portion. The heat transfer assembly includes a number of elongated bodies, a first heat transfer surface, and a second heat transfer surface. The first heat transfer surface is disposed on the conductive assembly. Each heat transfer assembly body includes a second heat transfer surface. Each heat transfer assembly body is coupled to the conductive assembly with the first heat transfer surface coupled to a number of second heat transfer surfaces.

High current vacuum interrupter with sectional electrode and multi heat pipes

An electrode assembly is provided for a vacuum switch, including a vacuum envelope, a fixed contact assembly including a fixed contact disposed within the vacuum envelope, and a movable contact assembly including a movable contact disposed within the vacuum envelope and movable between a closed position in electrical contact with the fixed contact and an open position spaced apart from the fixed contact. The electrode assembly includes at least one electrode bundle having a plurality of electrodes coupled to a corresponding one of the fixed contact assembly and the movable contact assembly. The electrodes extend from at or about a corresponding one of the fixed contact and the movable contact toward the closer of the first end of the vacuum envelope and the second end of the vacuum envelope.

Vacuum switch and electrode assembly therefor

A hybrid switch assembly is provided for a vacuum switch, such as for example a vacuum interrupter. The vacuum interrupter includes a vacuum envelope, a fixed contact assembly partially within the vacuum envelope, and a movable contact assembly partially within the vacuum envelope and movable between a closed position in electrical contact with the fixed contact assembly and an open position spaced apart from the fixed contact assembly. The hybrid switch assembly includes at least one radial magnetic field generating mechanism, such as for example a spiral contact or cup member, and a number of axial magnetic field generating mechanisms each comprising a ferromagnetic or ferrimagnetic member, such as for example, a horseshoe plate assembly. Each axial magnetic field generating mechanism is disposed within the vacuum envelope proximate a corresponding radial magnetic field generating mechanism.
