    摘要: The stock contains an insulating-material matrix and a filler embedded in the matrix and is distinguished by a cellular structure. The predominant portion of the cells is filled with a material having arc-extinguishing properties or contains a material which, on exposure to an arc, forms arc-extinguishing gas. For the purpose of improving the making and breaking capacity, such a stock can advantageously be employed in a gas-blast circuit breaker in which arc-extinguishing gas is blown onto the switching arc. This involves the stock preferably being positioned at such points guiding the arc-extinguishing gas, at which the stock is exposed to the radiation of the arc and the thermal action of arc gases.

    摘要: Extending between a fixed tulip contact (1) and a slide tulip (4) is an arcing chamber (5) which is occupied in the closed position by a movable contact pin (3) which fills up both an exhaust (9) surrounded by the slide tulip (4) and a blowout opening (7) which is surrounded by the tulip contact (1) and connects the arcing chamber (5) to a pressure chamber (6). The arcing chamber (5) is surrounded by an annular heating volume (13) open toward the same. Arranged in the pressure chamber (6) is a charge (10) of explosive which is for the most part converted within approximately 10-30 ms after ignition to extinguishing gas, preferably predominantly nitrogen, the gas pressure moving the contact pin (3) toward the open position. After clearance of the blowout opening (7) and the exhaust (9), the arc drawn between the contact pin (3) and tulip contact (1) is blown out, something which is supported by the pressure buildup, to which the arc contributes, in the heating volume (13). The pressure chamber with the charge can also surround the arcing chamber in an annular fashion. In this case, it is also possible to support the opening movement by the explosion pressure, for example, via pistons.

    摘要: Arranged in the continuation of an arcing chamber (16) bounded by consumable rings (32a, 32b) are pressure chambers (25a, 25b) which are connected in each case to a heating volume (18), which concentrically surrounds the arcing chamber (16), via a return channel (28; 28b), which is rotationally symmetrical with reference to the switching axis and is at least initially of increasing cross section, and a non-return valve (29a; 29b). A circumferential blowout slot (19) opening into the arcing chamber (16) between the consumable rings (32a, 32b) issues from the heating volume (18). The pressure chambers (25a, 25b) are, moreover, connected via in each case a plurality of exhaust tubes (34a, 34b) to exhaust volumes (30a, 30b) and to one of them also via a pressure relief valve (37). The pinch pressure produced between the consumable rings (32a, 32b) during formation of an arc (17) leads to a pressure buildup in the pressure chambers (25a, 25b) which contributes via the return channels (28a, 28b) to building up in the heating volume (18) a high blowout pressure which on the occasion of the next zero crossing causes a strong gas flow through the blowout slot (19) into the arcing chamber (16), which quenches the arc (17).

    摘要: The power breaker is provided with a contact arrangement which is equipped with erosion-resistant contact members and has a stationary contact member (4), a contact member (4) which can move along a central axis (6) and an insulating nozzle (6) which concentrically surrounds the contact members (3, 4) and has a constriction (6). The insulating nozzle (6) is manufactured from an erosion-resistant plastic and is structured such that erosion channels which are formed run at right angles to the direction of the electrical field load. This insulating nozzle emits gases during disconnection, which particularly effectively support the production of blowing pressure in the arc zone.

    摘要: A high-voltage circuit breaker includes two arcing contacts, which are capable of moving relative to one another along an axis, an insulating nozzle, a heating volume for accommodating quenching gas, a heating channel, and an overpressure valve. The pressure of the quenching gas is based on the energy of a switching arc, which is formed when the breaker opens and generates arcing gas, and the heating channel opens out, with axial alignment, into the heating volume. The heating channel connects an arc zone, and the overpressure valve limits the pressure of the quenching gas by opening a relief duct, which opens out into an expansion space. In high-current switching, the pressure of the arcing gases in the arc zone is limited, and the quality of the quenching gas stored in the heating volume is improved, due to the relief duct having an outflow section extending in the radial direction.

    摘要: The electrical insulator has an insulator body 3 which is fitted between an electrical conductor 1 and a grounded holder 2. The surface of the insulator is at least partially formed by a protective body 6. The material of the protective body has a low dielectric constant in comparison to that of the material of the insulator body 3. The protective body 6 prevents an electrically conductive particle 12 from coming to rest directly on the surface of the insulator body 3, in particular in the region of the triple points T, or causing a considerable increase in the field due to immediate proximity to the insulator body 3. The breakdown voltage of a gas-insulated system which contains such insulators provided with a protective body is increased. Gas-insulated systems can thus be made more compactly and more cheaply, and their life can be extended.

    摘要: In a fuse chamber (8) there is arranged as a quenching gas source a burn-off element (11), which concentrically surrounds an arc chamber (10) and is separated from it by a fuse element (9), which consists of metal foil, preferably silver foil, and the outer side of which is adjoined by the burn-off element (11). The latter consists of an igniting material (12), arranged in the form of a ring running around centrally, and a gas-evolving material (13). Both materials consist, for example, of guanidine or guanidine derivatives as the combustible material and an oxidant, the proportion of which in the igniting material (12) is hyperstoichiometric. The arc chamber (10) is bounded at opposite ends by nozzles (7a,b), which connect it to exhaust volumes (4a,b). When there is an overcurrent, the fuse element (9) heats up to the igniting temperature of the igniting material (12) and is torn open centrally. The arc forming is axially blown by the quenching gas, which forms during the burning-off of the burn-off element (11), and quenched. The fuse element (9) may centrally have a triggering zone, where it is more easily interruptible, in particular meltable. The quenching gas source may also comprise compressed-gas tanks or cold-gas generators.

    摘要: A device for switching electric current includes a compressed gas switch, at least one vacuum switch, and two terminals. A first consumable contact of the compressed gas switch is electrically connected to a first of the two terminals and a movable electrode of the vacuum switch is connected to a second of the two terminals to form a quenching circuit. The two electrodes of the vacuum switch can be separated without the use of the drive and a contact pressure is applied to them which prevents the electrodes from breaking below a threshold value of the current to be switched off. On switch-off, the current to be interrupted is switched over from a rated current circuit containing two rated current contacts of the compressed gas switch to the parallel quenching circuit. The vacuum switch now in the quenching circuit breaks only if the current to be switched off exceeds the aforementioned threshold. As the vacuum switch does not conduct the rated current and, unlike the compressed gas switch, is involved only in a few break operations, it can be of substantially lighter construction than a vacuum switch carrying the rated current and is actuated in every switching operation.
