Abstract: A method for operating a drive of a vacuum interrupter in opening mode includes: dividing an opening movement of at least one movable contact into serial phases, an opening phase, and an isolating phase, driven in at least two different velocities. In the opening phase a velocity of the opening movement is lower than in the isolating phase.

Abstract: A fixation system in use for medium or high voltage switching poles, insulators, circuit breakers, or general devices includes: an insulating housing provided with holes, in which screws are screwed into, in order to fix the device on a support, or a further housing. Inner surfaces of the holes are covered with a conductive layer or layers covering the inner surfaces at least partly. The conductive layers extend toward outside the holes. The conductive layers are conductively connected or connectable to ground potential.

Abstract: A medium voltage circuit switch or breaker includes: at least one movable contact; a fixed contact; and a mechanical or magnetical drive system, which moves the at least one movable contact to a closed or opened position by a movement of a rod and/or a lever. The mechanical or magnetical drive system is linked to a switching generating signal. The mechanical or magnetical drive system includes at least one pyrotechnical actuator or gas generator. The pyrotechnical actuator or the gas generator is linkable to the switching generating signal of the mechanical or magnetical drive system.

Abstract: A switching device including: one or more fixed contacts and one or more movable contacts, each movable contact being reversibly movable between an opening position, at which the movable contact is decoupled from a corresponding fixed contact, and a closing position, at which the movable contact is coupled with the corresponding fixed contact; an electromagnetic actuator adapted to actuate the movable contacts between the opening and closing positions, the electromagnetic actuator including a fixed yoke and a movable armature operatively associated with the fixed yoke to form a magnetic circuit, the movable armature being reversibly movable between a first position, which corresponds to the opening position of the movable contacts, and a second position, which corresponds to the closing position of the movable contacts; and a kinematic chain to operatively connect the movable armature with the movable contacts, wherein the electromagnetic actuator includes a first excitation coil and a second excitation coil wound around the fixed yoke. The switching device further include a first power drive circuit adapted to provide a first excitation current to the first excitation coil and a second power drive circuit adapted to provide a second excitation current to the second excitation coil; the first and second power drive circuits are galvanically separated one from another and capable of operating independently one from another.
