    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 switching point in a high- or medium-voltage switch contains two fixed contact members (1, 2), a rotating, electrically conductive bridging contact member (3), and a drive for moving the bridging contact member (3). When the switching point is closed, the bridging contact member (3) is fit in between the fixed contact members (1, 2) and short-circuits them. The drive is composed of two coils (5, 6) which surround the bridging contact member (3) and are arranged in such a manner that the bridging contact member (3) can be caused to rotate by a current in a respective one of the coils. The energy which needs to be applied to rotate the bridging contact member is less than for contact members which move in translation in comparable switching points. The energy required for opening and closing the switching point is thus reduced.

    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： This power breaker has an arcing chamber which is filled with an insulating medium and extends along a central axis (2). This arcing chamber is provided with a power current path which has two erosion contact arrangements (5, 6) which are arranged on the central axis (2), are at a constant distance from one another in the axial direction and bound an arcing zone. The arcing chamber also has a heating area (13), which is connected to the arcing zone, and a bridging contact which electrically conductively connects the erosion contact arrangements (5, 6) in the connected state. The bridging contact is arranged centrally in the interior of the erosion contact arrangements (5, 6). An annular gap (36) is provided between the erosion contact arrangements (5, 6) and opens directly into the heating area (13). In this power breaker, the flow behavior is significantly improved in the region between the arcing zone and the heating area (13).

    摘要： This power breaker has at least one quenching chamber, which is filled with an insulating medium, is of cylindrical design, extends along a central axis (2) and has a power current path, having two stationary consumable contact arrangements (5, 6) which are arranged on the central axis (2), are at a distance from one another in the axial direction and are arranged in the power current path. In the connected state, the consumable contact arrangements (5, 6) are electrically conductively connected by means of a moving bridging contact. An arc zone (24) is provided between the consumable contact arrangements (5, 6). A rated current path is arranged in parallel with the power current path. The power breaker is provided with at least one source for a highly pressurized insulating medium. The medium passes from this source directly into the arc zone (24), through at least one injection channel (62, 63). This high-pressure injection considerably improves the breaking capacity of the power breaker.

    摘要： The disclosure relates to a vacuum interrupter chamber having an insulating ceramic wall, within which contact pieces which move in a vacuum are arranged and are surrounded by a screen between the contact piece and the interrupter chamber wall. In order in this case to improve on the one hand the erosion resistance of the screen and on the other hand the dielectric strength of the arrangement, the disclosure proposes that coatings composed of high-melting-point material or composed of refractory metals be fitted at least partially in the area of the screen or other components within the vacuum interrupter chamber.

    摘要： The current-limiting switch (S) has an arc-resistant contact arrangement (K1), which is intended to carry the rated current (IN), of a first switching point (S1), and two commutation paths (P1 and P2) connected in parallel with the first switching point (S1). The first commutation path (P1) contains, in series, a contact arrangement (KT) of a second switching point (ST) and an electronic power switching apparatus (T). The second commutation path (P2) contains, in series, a switching apparatus (SA) and a current-limiting element (RB). The contact arrangements (K1 and KT) are designed to be coaxially symmetrical and are arranged in a pressure-resistant housing (G). Both switching points have electrodynamic drives which open and close very quickly. Thanks to the extremely space-saving, coaxial arrangement of the contact arrangements, undesirable stray inductances can be avoided. This allows the current-limiting switch to be switched on and off very quickly.
