Abstract
Description
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a device according to the preamble of claim 1.
Aus der WO 95/22167 ist eine derartige Vorrichtung bekannt geworden, die als Serienprodukt in Schaltanlagen Anwendung findet und sich im praktischen Einsatz bewährt hat. Die Abmessungen der Vorrichtung sind aber relativ groß.Such a device has become known from WO 95/22167, which as Series product is used in switchgear and is in practical use has proven. The dimensions of the device are relatively large.
Aus der DE 94 19 141 U1 ist ein Kurzschließer ohne elektrische Energiespeicher und Leistungsthyristoren bekannt, der als zylindrische Patrone nach dem Vorbild der WO 95/22167 jedoch mit einem integriertem Sprengsatz ausgeführt ist.From DE 94 19 141 U1 is a short-circuiter without electrical energy storage and Power thyristors known as the cylindrical cartridge modeled on the WO 95/22167, however, is designed with an integrated explosive device.
In dem Kurzschließer wird ein Gasdruck erzeugt, der einen Bolzen zur Erzeugung eines metallischen Kurzschlusses bewegt.A gas pressure is generated in the short-circuiter, which creates a bolt a metallic short circuit.
Zur Potentialtrennung ist ein Isolierring mit einer dünnen Membran vorgesehen. Der Anschluß von mindestens zwei Patronen an einem Sammelschienensystem ist nicht näher gezeigt.An insulation ring with a thin membrane is provided for electrical isolation. The It is not possible to connect at least two cartridges to a busbar system shown in more detail.
Der Bolzen muß die Wegstrecke des Isolierendes überwinden bis ein Kurzschluß erzeugt wird.The bolt must cover the distance of the insulating end until a short circuit is produced.
Kurzschließer mit einem Gasgenerator sind aus den DE 196 01 639 A1 und DE 42 36 623 A1 bekannt.Short-circuiters with a gas generator are known from DE 196 01 639 A1 and DE 42 36 623 A1 known.
Bekannt und üblich ist es, Stromschienen mit Schrauben oder Nietverbindungen miteinander zu verbinden. It is known and common to use busbars with screws or rivet connections connect with each other.
Aufgabe der Erfindung ist es, eine Vorrichtung unter Verwendung eines Gasgenerators nach dem Oberbegriff des Anspruches 1 zu schaffen, die schnell ist, mit wenigen Teilen realisiert werden kann, konstruktiv einfach und toleranzerhaben ist. Die Aufgabe der Erfindung wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst, während in den Unteransprüchen besonders vorteilhafte Weiterbildungen der Erfindung gekennzeichnet sind.The object of the invention is a device using a To provide gas generator according to the preamble of claim 1, which is fast can be realized with just a few parts, is structurally simple and has tolerances. The object of the invention is characterized by the characterizing features of Claim 1 solved, while in the subclaims particularly advantageous Developments of the invention are characterized.
Anhand der Zeichnung, in der ein Ausführungsbeispiel dargestellt ist, sollen die Erfindung, weitere Ausgestaltungen und Verbesserungen der Erfindung und weitere Vorteile näher beschrieben und erläutert werden.Based on the drawing, in which an embodiment is shown, the Invention, further refinements and improvements of the invention and others Advantages are described and explained in more detail.
Es zeigt:It shows:
Fig. 1 eine Prinzipdarstellung der Vorrichtung im isolierten Zustand, Fig. 1 is a schematic representation of the device in the isolated state,
Fig. 2 eine Prinzipdarstellung der Vorrichtung im kurzgeschlossenen Zustand, Fig. 2 is a schematic representation of the device in the short-circuited state,
Fig. 3 eine weitere Darstellung der Vorrichtung im isolierten Zustand und Fig. 3 shows a further illustration of the device in the isolated state and
Fig. 4 eine weitere Darstellung der Vorrichtung in kurzgeschlossenem Zustand. Fig. 4 shows a further illustration of the device in the short-circuited state.
In der Fig. 1 ist die Vorrichtung zur elektrischen Verbindung von Stromschienen 2, 3 unter Verwendung eines pyrotechnischen Gasgenerators 4 gezeigt.In FIG. 1, the device for electrical connection of busbars 2, 3 shown using a pyrotechnic gas generator 4.
Eine erste Stromschiene 3 oder ein elektrisches Leitelement 5 ist mit einem leitfähigen Gehäuse 6 verbunden, in das der pyrotechnische Gasgenerators 4 gasdicht eingebettet ist. A first busbar 3 or an electrical guide element 5 is connected to a conductive housing 6 , in which the pyrotechnic gas generator 4 is embedded gas-tight.
Das Gehäuse 6 wird nach einer Zündung durch den Innendruck plastisch deformiert bzw. aufgebläht, derart daß eine zweite Stromschiene 2 elektrisch kontaktiert wird. Die zweite Stromschiene 2 weist einen rechteckförmigen Querschnitt mit einer Schmalseite 7 und einer Breitseite 8 auf. An der Breitseite 8 ist eine zylindrische Bohrung 10 angeordnet, in der das Gehäuse 6 isoliert angeordnet ist, wobei das Gehäuse 6 auch zylinderförmig ist.After ignition, the housing 6 is plastically deformed or inflated by the internal pressure, such that a second busbar 2 is electrically contacted. The second busbar 2 has a rectangular cross section with a narrow side 7 and a wide side 8 . A cylindrical bore 10 is arranged on the broad side 8 , in which the housing 6 is arranged in an insulated manner, the housing 6 also being cylindrical.
Zwischen dem Gehäuse 6 und der zweiten Stromschiene 2 ist ein Luftspalt als Isolierspalt 9 vorhanden ist.An air gap is present as an insulating gap 9 between the housing 6 and the second busbar 2 .
Der Isolierspalt 9 kann mit einer Flüssigkeit, SF6 oder Isolierstoff gefüllt sein oder ein Vakuum aufweisen. The insulating gap 9 can be filled with a liquid, SF6 or insulating material or have a vacuum.
