The present invention relates to a device for lifting a circuit breaker of a switchgear, the device comprising: a rail part that is located above the switchgear and has a plurality of vertically arranged compartments; an elevating part that can be guided and move above the rail part, and lifts the circuit breaker; and a lifting bracket that is fixed to two facing side surfaces of the circuit breaker, is coupled to a hook block of the elevating part, and moves up and down according to the actions of the elevating part.

A device for monitoring vacuum quality of a vacuum circuit breaker, the device including at least one rigid assembly including a first stationary conductive surface that is separated by an insulating layer from a second stationary conductive surface that is grounded. The assembly forms a first capacitor having a fixed value, the first stationary conductive surface being arranged opposite an electrically active portion of the vacuum circuit breaker to form, together with the portion, a second capacitor, and an electronic circuit for measuring a variation in voltage of the first capacitor that is representative of a change in state of the vacuum of the circuit breaker.

An automatic autonomous redundant switch configured for providing energy from either a first power source or a second power source to a load is provided. The automatic switch includes a first automatic transfer switch (ATS) and a second ATS. The automatic switch further includes an interconnecting bus configured to connect the first ATS and the second ATS, and at least one controller configured to control the operation of the first ATS and the second ATS. Still further, the first ATS and the second ATS each include a respective transfer-switch mechanism, a respective bus attachment configured to connect to the interconnecting bus, and a respective motorized rack-out mechanism having a powered actuator.

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.
