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 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.
