  Schutzeinrichtung elektrischer Leitungen gegen    Störungswellen.   



    Gegenstand des Stammpatentes ist eine Einrichtung zum Schutze elektrischer Leitungen gegen Störungswellen, bei denen die Wellen an den Enden einzelner Streckenabschnitte durch besondere Einrichtungen, z. B. Drosselspulen in den Leitungen und Kondensatoren parallel zu den Leitungen, oder Widerstände, die die Energie der auftreffenden Störungswellen absorbieren, aufgehalten werden und dort durch Auslöserelais das Abschalten des gestörten Leitungsteiles bewirken. Als Ausführungsbeispiele sind Anordnungen dargestellt, bei denen Auslöserelaiskreise an Drosselspulen angeschlossen sind, die in der Hauptleitung liegen.

  Protection device for electrical lines against interference waves.



    The subject of the parent patent is a device for the protection of electrical lines against interference waves, in which the waves at the ends of individual route sections by special devices, such. B. choke coils in the lines and capacitors parallel to the lines, or resistors that absorb the energy of the incident interference waves, are stopped and there cause the disconnected part of the line to shutdown by a trip relay. As exemplary embodiments, arrangements are shown in which trip relay circuits are connected to choke coils which are located in the main line.

Man erhält nun eine ausserordentlich günstige Einrichtung nach dem Stammpatente, wenn man die Auslöserelaiskreise im Kondensatorkreis parallel zu den Leitungen anordnet. Die Zeichnung veranschaulicht eine derartige Einrichtung. nl, n2 sind die Leitungen, Sl, S2 die Schalter, die durch die Auslöserelais betätigt werden sollen. I ist eine Drosselspule, Cj, c2 zwei Kondensatoren, die zwischen Leitung und Erde geschaltet sind. In die Kondensatorkreise werden nun die Auslöserelaiskreise eingeschaltet, entweder direkt oder, wie es als Ausführungsbeispiel in der Zeichnung veranschaulicht ist, über Transformatoren. In den Kondensatorkreisen liegen demnach die Primärwicklungen von Transformatoren t, i's, in deren Sekundärkreis Auslöserelais rl, r2 angeordnet sind, Diese Anordnung hat zwei erhebliche Vorteile. An extraordinarily inexpensive device according to the parent patent is obtained if the trip relay circuits are arranged in the capacitor circuit parallel to the lines. The drawing illustrates such a device. nl, n2 are the lines, Sl, S2 are the switches that are to be operated by the release relay. I is a choke coil, Cj, c2 two capacitors connected between line and earth. The trip relay circuits are now switched into the capacitor circuits, either directly or, as illustrated as an exemplary embodiment in the drawing, via transformers. The primary windings of transformers t, i's, in the secondary circuit of which tripping relays r1, r2 are arranged, are located in the capacitor circuits. This arrangement has two significant advantages. Erstens ist die Menge der Störungsenergie, die durch die Kondensatorkreise parallel zu den Leitungen abfliesst, erheblich grösser alsdie Energie, die bei den Ausführungsbeispielen des Stammpatentes an den Klemmen der Drosselspule zur Verfügung steht. Die Transformatoren t werden also von starken Strömen durchflossen. Die Auslöserelais werden dementsprechend schnell und kräftig betätigt. Firstly, the amount of interference energy that flows through the capacitor circuits parallel to the lines is considerably greater than the energy that is available at the terminals of the choke coil in the exemplary embodiments of the parent patent. The transformers t are therefore traversed by strong currents. The trip relays are activated accordingly quickly and powerfully. Ein weiterer Vorteil dieser Anordnung besteht darin, dass Auslöserelaiskreise mit ihren Transformatoren unmittelbar an Erde gelegt werden können, also nicht der hohen Isolierung bedürfen, die sie bei Anordnungen in oder an den Leitungen selbst haben müssten, PATENT-ANSPRUCH : Schutzeinrichtung elektrischer Leitungen gegen Störungswellen nach Patent Nr. 75036, dadurch gekennzeichnet, dass die mit den Leitungen gekuppelten Auslöserelaiskreise (rl'r2, unmittelbar oder über einen Transformator (tel,'2) an den Kondensatorkreis angeschaltet sind. Another advantage of this arrangement is that trip relay circuits with their transformers can be connected directly to earth, i.e. they do not require the high level of insulation that they would have to have for arrangements in or on the lines themselves Patent No. 75036, characterized in that the trip relay circuits (rl'r2, coupled to the lines, are connected to the capacitor circuit directly or via a transformer (tel, '2). *) tstes'Zusatzpatent Nt. 84241, zweites Zusatzpatent Nr. 84341.
