A shutter device is disclosed for an electric switchgear panel, including a base configured to be placed on a bearing surface inside the switchgear panel, the base being adapted to support, positioned thereon, a current switching device movable between a connected position wherein the switching device is electrically connected to an associated electrical circuit and a disconnected position wherein the switching device is electrically separated from the corresponding electrical circuit, a frame having at least a portion which rises up transversally from the base and delimits a through aperture, a movable shutter operatively associated with the base and the frame and an actuating mechanism adapted to move the shutter between a first position where the shutter closes at least partially the through aperture and a second position wherein the shutter is retracted and leaves the through aperture at least partially opened.

Shutter device for an electrical switchgear panel, and related switchgear panel

A medium voltage switchgear () which is characterized in that it comprises a casing () defining an internal volume for housing at least a circuit breaker assembly () movable between at least two operative positions, said casing comprising a front panel () provided with an opening () for the insertion of an operating handle () for actuating the movement of said circuit breaker assembly between said operative positions, a closing and retaining device () being positioned in correspondence of said opening () and movable between a closed position when said operating handle is not inserted and an open position for allowing insertion of said operating handle, said closing and retaining device () comprising locking means for retaining said operating handle in position when inserted in said opening.

Medium voltage switchgear

Electric switchgear comprising a casing having at least one compartment provided with a door, a plurality of electrical conductors suitable to be connected to a load, a multi-phase switching device which is mounted on a truck movable inside the compartment between a connected position wherein each phase of the switching device is electrically connected to a corresponding electrical conductor and a withdrawn position wherein each phase of the switching device is electrically separated from the corresponding electrical conductor, and an earthing switch comprising a plurality of contacts for connecting to earth the plurality of electrical conductors. The earthing switch is actuated to move between a first position wherein each contact is electrically connected to a corresponding electrical conductor and a second position wherein each contact is electrically separated from the corresponding electrical conductor by the movement of the truck between the connected position and the withdrawn position.
