    摘要： The invention relates to a load-break switch with a main contact point and an arc rupture contact point, the main contact point being opened upstream of the arc rupture contact point for disconnection and being closed downstream of the arc rupture contact point for connection. The load-break switch comprises a stationary and a mobile contact element arrangement, the stationary contact element arrangement having a pot-shaped contact element with contact fingers and the mobile main contact element having a contact cylinder that is connected to a contact support. The arc rupture point comprises a contact pin as the stationary contact element and an annular contact element as the mobile contact element. The contact pin (18) comprises a section (34) from a tear-proof material having an outer diameter that is larger than the outer diameter of the remaining pin section. The contact pin (18) is provided with at least one longitudinal slot that divides the pin into at least two pin fingers.

    摘要： The subject of the invention is a device for suppressing very fast transients (1,1a, 1b), applicable in protecting electric and/or electric power equipment, and especially transformers operating in electric power substations and in wind power plants, connected in the supply network circuit downstream of the circuit breaker and upstream of the protected equipment. The device according to the invention is a component of an induction character (1, 1a, 1b), comprising a high-frequency magnetic core (2) arranged around the current-conducting lead (3). On the magnetic core (2) there is wound at least one winding (4, 4a) with at least one pair of terminals (6) used for connecting at least one damping resistor (7). The inventive device contains an insulating body (8) in which there is located a magnetic core (2) together with a damping resistor (7) and a winding (4, 4a) or contains an insulating body (8a) in which there is located a magnetic core (2) together with a damping resistor (7), a winding (4, 4a) and a section of a current-conducting lead (3).

    摘要： The invention relates to a switchgear comprising at least two panels, at least one of which is provided with a switch-disconnector. Each panel encompasses at least one front wall, a rear wall, a bottom wall, a top wall, a wire feed, and busbars which embrace at least one panel. Each panel is configured in a modular fashion and forms a first module. One respective support element to which one respective switch-disconnector can be fixed is fastened between the front wall and the rear wall of each module, said support element being connected in a fixed manner to the front wall and/or the rear wall. The switch-disconnectors and the support element of both modules are located on the same level and are configured in an identical manner.

    摘要： The invention relates to a load disconnecting circuit with a housing that has a first housing section, which houses the drive, and has a second housing section, which houses a fixed contact element and a longitudinally extended moving contact element. The second housing section has a longitudinal extension adapted to the moving contact element. Field-control rings are placed on the second housing section while encircling it, of which the first are arranged in the vicinity of the fixed contact element and the second are arranged in the vicinity of the switch-off position of the moving contact element. Via a respective connection conductor, the first field-control ring is connected to the potential of the fixed contact element, and the second field-control ring is connected to the potential of the moving contact element when in its switch-off position.
