Abstract: A switch system includes a mechanical switch for electrical currents. The mechanical switch operates in a conductive state and in a non-conductive state. A first actuator is configured to change the state of the mechanical switch, wherein an actuation of the first actuator is based on a Thomson coil system. A second actuator is also configured to change the state of the mechanical switch and includes a loaded spring system locked by a latch system. Each of the first and second actuators is configured to change the state of the mechanical switch depending on a property of an electrical current passing through the mechanical switch.

Abstract: Described herein is a VI assembly that includes a VI having a stationary contact on a stationary contact potential, a moveable contact on a moveable contact potential, and a vapor shield. The stationary and moveable contacts define a contacting area. The moveable contact is moveable relative to the stationary contact along an axis of the VI. The VI assembly further includes at least one field coupler. The stationary contact and the vapor shield have a predetermined stationary contact-vapor shield capacitance with respect to each other. The moveable contact and the vapor shield have a predetermined moveable contact-vapor shield capacitance with respect to each other. The field coupler is configured such that it adds a field coupler capacitance to at least one of the stationary contact-vapor shield capacitance and the moveable contact-vapor shield capacitance to make the stationary contact-vapor shield capacitance and the moveable contact-vapor shield capacitance substantially equal.

Abstract: A switching apparatus includes first and second electric terminals, and first and second electric branches comprising one or more switching devices. The second electric branch is electrically connected in parallel with said first electric branch between said first and second electric terminals. The switching apparatus comprises a current blocking circuit adapted to block a current along said second branch. The current blocking circuit includes a first switching device of solid-state type and a first electronic circuit electrically connected in parallel to said first switching device of solid-state type. The switching apparatus further comprises a current limiting circuit adapted to limit a current flowing along said second electric branch. Said current limiting circuit is electrically connected in series with said current blocking circuit and it includes a second switching device of solid-state type and a second electronic circuit electrically connected in parallel to said second switching device of solid-state type.

Abstract: A switching apparatus for an electric grid includes first and second electric terminals, each having first and second electric branches having a plurality of switching devices. The first electric branch includes a first switching device switchable between open and closed states, which is driven by a current flowing along said first switching device and without receiving an external control signal or an external power supply, said first switching device switching from said closed state to said open state, when the current flowing along said switching apparatus exceeds a corresponding predefined threshold value or when the changing rate of the current flowing along said switching apparatus exceeds a corresponding predefined threshold value or upon a combination of these two conditions. A second switching device is connected in series with the first switching device and is switchable between closed and open states upon receiving a corresponding input control signal.
