A sealed solenoid, magnetically operated electric power switch is suitable for use as capacitor, line and load switch operating at transmission and distribution voltages that includes no dynamically moving seals through the sealed container housing the contactor portion of the switch. The sealed solenoid switch includes a magnetically operated drive system with an actuator that magnetically couples across the container wall to avoid the use of a moving or sliding seal as part of the drive system. The sealed solenoid switch may also include a ballast resistor and resistor contact located inside the sealed container to avoid another seal as part of the ballast system. A magnetic latch holds the switch in a closed position, and a spring holds the switch in the closed position, to avoid the need for an energizing current to maintain the switch in either position.

A folding high voltage electric power switch that can be fully assembled, tested and adjusted at the factory and then folded for shipping on a road truck with minimal disassembly. The switch can then be readied for installation with minimal field assembly largely limited to unfolding and securing support beams and struts. The switch includes a number of phase insulators (i.e., two phase insulators for a 2-way switch and three phase insulators for a three-way switch), a central switch insulator and a number of blade arms, each selectively connecting an electric power tap at the central insulator to an electric power tap at a respective phase insulator. The platform includes structural beams and struts that easily fold for transportation and unfold for installation in the field while the beams, struts, insulators and blade arms remain attached together.

A magnetic interrupter consisting of a stationary and moving butt contacts that open an electric circuit in dielectric gas (e.g., SF) 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.
