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： A wreath of contact fingers (4) directed radially toward a switching axis (1) presses in the closed position against the circumferential surface of a contact pin (2) with consumable heads (5) fitted on the ends. At an angle of approximately 90.degree., the contact fingers (4) adjoin webs (6) which are guided in the closing direction up to a housing part (7) at which they are permanently anchored and via which they connect the contact fingers (4) to an electric terminal. The webs (6) and--with the exception of the consumable heads (5)--the contact fingers (4) are produced in one piece from springy material of high conductivity. The contact with the contact pin (2) radially deflects the consumable heads (5) in the closing direction with elastic bending of the webs (6). The length (R) of the radial contact fingers and the length (L) of the axial webs (6) are selected such that the attraction of the parallel component currents through the latter approximately compensates the contact repulsion forces.

摘要： In the switched-on position, under the influence of contact forces generated by elastic deflection or else by mechanical spreading, or spreading caused by the attraction of parallel currents or repulsion of antiparallel currents, of a switching pin (5) , the switching pins presses against the inner side of a first switching ring (4), which is rigid for the purpose of avoiding mechanical overloading and securing sufficient consumable reserves. By way of example, a support (30) of the switching pin (5) is adjoined by two parallel, elastic extensions (52a, 52b), which are separated by a slot (53) and respectively support a contact member (54a; 54b) by means of a connecting element (55a; 55b) forming half a screw thread, with the result that said contact member is in each case offset by 180.degree. relative to the extension (52a; 52b). In the switched-on position, therefore, the contact members (54a, 54b) are forced apart by the elastic deformation of the extensions (52a, 52b) which is caused by the attraction between the parallel partial currents through said contact members. The switching pin (5) is electrically conductively connected to a second switching ring (6), which is separated from the first switching ring (4) by an arc space.
