摘要: A portable motorized racking device and system are disclosed for remotely racking (inserting or removing) drawout circuit breakers. The racking device provides a portable, motorized device that can be hand carried to a work location and affixed to the circuit breaker without the need of any modification to the breaker or its enclosure. In one embodiment, among others, the torque that is required to operate the breaker racking mechanism is provided by an electrically powered gearmotor. Attached to the output shaft of the gearmotor is a socket that engages the circuit breaker racking screw. An anti-rotation plate engages a feature, such as a bolt head, opening, hole, or edge, on the racking screw support frame or the breaker face to prevent the gearmotor from rotating while the socket rotates the racking screw.

摘要: An apparatus is configured for use with a switchgear assembly having a frame that defines at least one switchgear cell, stationary disconnects oriented vertically on the frame, and horizontal draw-out disconnects remote from the frame. In a given example, the apparatus includes an adapter assembly including vertical disconnects, horizontal disconnects, and bus work connecting the vertical disconnects with the horizontal disconnects. The adapter assembly is configured to take an installed position in the switchgear cell, with the vertical disconnects in the adapter assembly projecting upward into engagement with the stationary disconnects on the frame. The adapter assembly is further configured for the horizontal disconnects in the adapter assembly to engage and disengage from the horizontal draw-out disconnects upon movement of the horizontal draw-out disconnects horizontally into and out of engagement with the adapter assembly when the adapter assembly is in the installed position.
