    摘要: A method for operating an electrical power supply network is described. The power supply network has several levels of different voltages. The levels are interconnected by switches. A first switch is made so that the maximum interruptible short-circuit current of the first switch is smaller than the maximum flowing short-circuit current. In the event of failure, a test is made as to whether the short-circuit current presently flowing through the first switch is smaller than the maximum interruptible short-circuit current. The first switch will remain closed if this is not the case, and the first switch will be opened if this is the case.

    摘要: The impact signaling system (9) is used in a high-voltage protective device and has a housing (13), a spring (16) which is arranged in the housing (13) and has a moveable end, an actuator (17) which can be passed out of the housing (13) and interacts with the moveable end of the spring (16), a high-resistance resistor wire (12) which is connected in parallel with a fusible wire of the protective device, and a holder which absorbs the prestress of the spring (16). The holder contains a section of the high-resistance resistor wire (12) which is in the form of a winding (18) and is passed at least once around the moveable end of the spring (16) in order to form the prestress, and which is at least partially in thermally conductive contact with the material of the activator (20). Above a limit temperature, the activator (20) lifts, for example by destruction of the winding (18) or by melting through, the holder and activates the impact signaling system (9) by reducing the load on the spring (16).

    摘要: A fuse has a fuse element (6) with a fusible conductor (7) of a conductor material (8) such as Ag, Cu or Al and is provided with doping points (9) following one another at regular intervals. There, the conductor material (8) has a directly adjoining layer of a first compound (10) of the same with a doping material such as In or Ge. It forms mixed crystals which contain the conductor material (8) and the doping material in a fixed stoichiometric ratio, such as for example Ag2In, and is separated from said conductor material by a stable phase boundary. The doping points (9) weaken the fusible conductor by lowering the melting point to below 250° C., so that arc formation rapidly occurs there when there are short-circuit currents, although its electrical resistance per unit of length is under some circumstances only a few percent greater than in the remaining region. The fusible conductor (7) bears a continuous layer of a burn-up material (12). It has an ignition temperature which is preferably lower than the melting point of the first compound (10).

    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.
