Abstract: A vacuum chamber contact assembly includes a vacuum housing assembly, a conductor assembly, and an operating mechanism. The vacuum housing assembly defines a sealed enclosed space. The conductor assembly includes a first stationary conductor assembly, a second stationary conductor assembly, and a movable conductor assembly. The operating mechanism includes a number of stationary components, a number of movable components and an actuator/latch assembly. The movable conductor assembly and the operating mechanism movable components are disposed entirely within the vacuum housing assembly enclosed space. The actuator/latch assembly includes an open, first latch unit and a close, second latch unit. The actuator/latch assembly is structured to maintain the movable conductor assembly in both the first position and the second position.

Abstract: A medium or low voltage circuit interrupter includes a housing with a first end cap, a second end cap that comprises a radial bellows, and one or more insulating sidewalls that extends from the first end cap to the second end cap. The end caps and one or more sidewalls provide a vacuum chamber. A fixed contact that extends through an opening of the first end cap and into the vacuum chamber. A moveable contact that extends through an opening of the second end cap and into the vacuum chamber. Multiple such interrupters may be electrically connected in series, positioned a single plane, and actuated by a single actuator.

Abstract: A circuit interrupter system includes a vacuum circuit interrupter having a vacuum chamber that contains a fixed contact and a moveable contact. A non-conductive rod extends from the moveable contact. One or more Thomson coils are wound around the rod, and one or more armatures are connected to the rod. When a driver energizes one of the Thomson coils, a corresponding armature will be repelled from that Thomson coil and move the rod to open or close the contacts of the vacuum circuit interrupter. The system also may include a damper that provides an active damping force rod when the rod is moved to open and/or close the vacuum circuit interrupter.

Abstract: Coil-based actuators for use in opening and closing the separable contacts of circuit interrupters provide increased initial velocity for opening strokes and damping at the end of opening strokes. Electronics for adjusting the current profile of current supplied to coil-based actuators additionally provide increased initial velocity for opening strokes and damping at the conclusion of opening strokes.
