摘要： A hybrid superconductive device for stabilizing an electric grid comprises (a) a magnetic core arrangement at least partially carrying an AC winding the AC winding connectable to an AC circuit for a current to be limited in the event of a fault; (b) at least one superconductive coil configured for storing electromagnetic energy; the superconductive coil magnetically coupled with the core arrangement and saturating the magnetic core arrangement during use. The hybrid superconductive device further comprises a switch unit preprogrammed for switching electric current patterns corresponding to the following modes: at least partially charging the superconductive coil; a standby mode when the superconductive coil is looped back; and at least partially discharging the superconductive coil into the circuit.
Optionally, hybrid superconductive device comprises at least one passage located within said magnetic flux. The passage conducts a material flow comprising components magnetically separable by said magnetic flux.-

摘要： A modular switching contactor arrangement for use in a safety-oriented application, has two switching contactor modules that can be arranged in succession by means of a coupling module, the switching contactor modules and the coupling module merely having to be joined together by a user, without any external wiring, so as to be mechanically and electrically coupled to one another. In the mounted state, the switching contactor arrangement has a reduced construction width that is substantially delimited by the narrow faces of the switching contactor modules. In particular, the construction width can be 22.5 mm.

摘要： A relay includes: a housing, a base plate, and a driving device, connected to the base. At least one stationary contact group is provided on the housing. The stationary contact group includes two stationary contacts insulated from each other. At least one stationary contact in the stationary contact group includes an upper terminal and a lower contact are included. The upper terminal and the lower contact are isolated from each other and electrically connected by a fuse. The base plate is provided in the housing and can switch between on and off positions. The base plate, when being in the on position, contacts the stationary contact group for the electrical conduction of the two stationary contacts in the stationary contact group, and, when being in the off position, is isolated from the stationary contact group for disconnecting the electrical conduction of the two stationary contacts in the stationary contact group.

摘要： A switch comprises a first elastic element, an actuator-element mechanically coupled to a first side of the first elastic element, and a first switching conductor, mechanically coupled to a second side of the first elastic element. The switching conductor is configured for moving between a first conductor position and a second conductor position. The actuator-element is configured from moving between a first actuator-element position and a second actuator-element position separated by a predefined actuator-element lift, thereby moving the first side of the first elastic element. The first elastic element moreover is configured for converting a movement of the first side of the first elastic element by the predefined actuator-element lift into the movement of the second side of the first elastic element with a predefined elastic force.

摘要： There is provided a contact switching device which has high productivity and in which operation characteristics hardly vary. The contact switching device includes an electromagnetic unit, a holder, a movable shaft, a movable yoke, a movable contact piece having movable contacts at both ends, fixed contacts, and a fixed yoke. At the time of excitation of the electromagnetic unit, the movable shaft moves to the holder side along a direction of an axis center. A magnetic circuit is formed of the fixed yoke and the movable yoke due to a magnetic field generated by a current that flows into the movable contact piece as a result of the movable contacts coming into contact with the fixed contacts. The movable yoke is then attracted to the fixed yoke.

摘要： A contactor includes a pair of fixed contacts, a movable contact element configured to contact the pair of fixed contacts and to be separated from the pair of fixed contacts, a movable shaft configured to move in an axial direction as to cause the movable contact element to contact the pair of fixed contacts and to be separated from the pair of fixed contacts, and a partition-wall component disposed opposite to the pair of fixed contacts with respect to the movable contact element. The first partition-wall component includes a partition wall provided around the movable shaft. The first partition wall is configured to move synchronously with at least one of the movable contact element and the movable shaft.
