A switchgear apparatus configured for operation at voltages up to 72.5 kV includes a vacuum interrupter assembly having a fixed contact and a movable contact configured to move relative to the fixed contact between a closed position in which the movable contact is in contact with the fixed contact and an open position in which the movable contact is spaced from the fixed contact. The switchgear apparatus also includes an electromagnetic actuator configured to move the movable contact between the open position and the closed position, a manual trip assembly movable from an initial position to an actuated position to move the movable contact from the closed position to the open position, and a mechanical interlock assembly configured to prevent the movable contact from moving from the open position to the closed position when the manual trip assembly is in the actuated position

A switching apparatus for electric power distribution grids including: a withdrawable first switching unit having one or more first electric poles; a withdrawable second switching unit having one or more second electric poles and electrically connected ins series with said first switching unit; and a controller implementing control strategies directed to increase the safety of the withdrawal manoeuvres of said first and second switching units.

An electrical switch for interrupting a current path. The switch includes a contact point formed from a first and a second contact piece mounted such that it can move about a rotation axis. The contact point is closed when the two contact pieces are in contact and is electrically opened when the two contact pieces are not in contact. The electrical switch includes an actuator unit and an electrically non-conductive separating element which can be moved in a translatory manner by means of the actuator unit and is designed to isolate the two contact pieces and then to keep the two contact pieces apart. The actuator unit includes a movement element mechanically coupled to the separating element, a drive device designed to move the movement element in order to close the contact point, a device for generating and/or storing kinetic energy and an electromagnetic actuator.

The invention disclosed is an arc protection system for an electrical switch mounted in an electrical cabinet. The system includes an arc suppression housing pivotally mounted in the electrical cabinet. The housing comprises an arc extinguishing chamber having an opening configured to face separable contacts of an electrical switch mounted in the cabinet when the housing has been rotated about the pivot into a closed position. The arc extinguishing chamber is configured to extinguish an electric arc produced by opening the separable contacts when the housing is in the closed position. The system further includes an interference mechanism mounted on the arc suppression housing. The interference mechanism is configured to prevent closure of an access door of the electrical cabinet, when the housing has been rotated about the pivot into an open position configured to enable operator access to the separable contacts of the electrical switch.
