Abstract

See full text

A magnetic interrupter consisting of a stationary and moving butt contacts that open an electric circuit in dielectric gas (e.g., SF6) contained in a sealed, pressurized insulating housing. One or both of the contacts contain a magnet with poles spaced apart in a radial plane perpendicular to the axial direction to spin the arc in the radial plane about the center of the contacts. Permanent magnets may be used to spin the arc so that the magnetic field is not affected by the magnitude of the arcing current, which makes the magnetic interrupter suitable for interrupting currents below fault level currents. One or both of the magnets may also be a field coil and a permanent magnet may be used in combination with a field coil.
