    摘要: A method and an apparatus are disclosed for disconnection of a fault current which has occurred in an AC power supply system. A disconnection command which is produced in a protective device is supplied to a synchronization controller in order to open a circuit breaker, in which synchronization controller a command is delayed until the circuit breaker can be opened in synchronism with the power supply system. The method includes monitoring of the disconnection command emitted from the protective device and monitoring a fault-current signal, or a status signal emitted from the circuit breaker, and formation of an emergency disconnection command if the fault-current signal or the status signal is still present following a delay time after emission of the disconnection command, which delay time is greater than a sum of a natural response time of the circuit breaker and a time for quenching of a switching arc produced on opening of the circuit breaker.

    摘要: The switchgear assembly has a polyphase design and has a gas-filled, modular encapsulation for each phase. Provided as the modules are at least one busbar (51, 52), which is guided predominantly horizontally, a circuit breaker (10) and two combined disconnecting-earthing switches (71, 72, 73) of identical design and having a disconnection and grounding function. A first one (71) of the combined disconnecting-earthing switches supports a section of the busbar (51) and is connected between the busbar (51) and a first current terminal (11) of the circuit breaker (10). The second combined disconnecting-earthing switch (73) is connected between an outgoing feeder (60) or a further busbar of the assembly and the second current terminal (12) of the circuit breaker (10). The combined disconnecting-earthing switches (71, 72, 73) are aligned such that two drive apparatuses (81, 82, 83), which are provided for their actuation, point in the same, predominantly horizontal direction. This switchgear assembly is of compact design since the drives of the combined disconnecting-earthing switches are guided in one direction and sections of the assembly which are connected to the combined disconnecting-earthing switches are guided in the opposite direction. If the drives point towards a control aisle of the assembly, the positions of the drives (81, 82, 83) and therefore the switching positions of the combined disconnecting-earthing switches (71, 72, 73) are visually easily accessible to the operator of the assembly.

    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: Current electronic cards, such as, for example, proximity cards, smartcards for short, can transmit data to a reader unit over a range of up to about 10 cm. Boosters are used to improve convenience which in essence represent a wireless extension. This is however not adequate with regards to autonomy, function (as a result of termination) and for the differing applications. A method is disclosed in which the transmission of service-specific codes, stored on a number of different smartcards, to a portable device is carried out. The portable device then transmits one or more of the codes via several different communication connections so that access to a service can be activated. By providing services to the corresponding authorized communication connection a modular system is achieved, permitting multiple access for a user to services.

    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: A method for setting up a secure communication line between a user and a service provider using non-secure communication channels within an insecure network, comprising the steps of transmitting an identity token from a user station to a service provider station both coupled to the insecure network; upon reception of the identity token, triggering the creation of a secret URL by the service provider station; transmitting the secret URL within a secure side channel to the user station; obtaining, within the user station, the secret URL, and setting-up a new communication path in the insecure network linking the user and the service provider station based on said secret URL. Beside discarding a man-in-the-middle by denying him access to the data flow it is also possible to stop him through denying him access to the content of the data flow. Such access can be denied through use of a one-time codebook with semantics only known to the User and the authentication service provider.

    摘要: A method to conduct fingerprint verification provides a sector distribution based on the position and angle of every minutiae vector, wherein the number of further minutiae vectors of the template in any sector of the sector distribution is determined and a feature vector is generated for every minutiae vector of both templates. The two feature arrays are matched by calculating the scalar product for every combination of said vectors generating a matrix. Mated pairs of minutiae from the first second template are found by searching the maximum element in every column of the matrix finally issuing a value representing identification information of the fingerprint. Additionally a false finger identification method and a fingerprint verification system are disclosed.

    摘要: The gas-insulated, metal-enclosed switchgear assembly contains two, three or more switchpanels, each having a multipole power breaker (CB.sub.1, CB.sub.2, CB.sub.3, CB.sub.4) as well as isolating and grounding switches per switch pole (CB.sub.1R) and is designed like a ring or in a 11/2 power-breaker circuit. The switch poles of the power breakers are each of identical design and are arranged parallel to one another. The switchpanels each have one current path of U-shaped design per phase in a vertical plane, in which current path the base of the U contains a vertically aligned pole of the power breaker, and the two limbs of the U each contain an electrical connection of the power breaker and an isolating as well as a grounding switch. The upper limbs of the U of one of the switchpanels are connected phase-by-phase to the lower limbs (S.sub.u) of another of the switchpanels, by means of respective single-phase gas pipelines (L.sub.12 (R), L.sub.23 (R), L.sub.34 (Y)) which are arranged inclined to the vertical and are designed in straight lines. Such a switchgear assembly is distinguished by compact construction.
