Description

Einrichtung zur Schnellunterbrechung von Kurzschlußströmen Zusatz zum Zusatzpatent: 1141015 Das Patent 1141015 betrifft eine Einrichtung zur Schnellunterbrechung von Kurzschlußströmen mit mehreren in Reihe geschalteten Unterbrechungsstellen, die durch Aufsprengen des Stromleiters gebildet werden (Sprengtrenner). Dabei benötigt jeder Sprengtrenner eine Sprengstoffkapsel, die ein Leiterstück zu zerlegen hat. Der Zündstrom für die einzelnen Sprengstoffkapseln soll, insbesondere um den Aufwand möglichst klein zu halten, einer gemeinsamen Zündstromquelle entnommen werden.Device for the rapid interruption of short-circuit currents Addendum to the additional patent: 1 141 015 The patent 1141015 relates to a device for the rapid interruption of short-circuit currents with several interruption points connected in series, which are formed by bursting the current conductor (explosive separator). Each separator needs an explosive capsule, which has to dismantle a section of ladder. The ignition current for the individual explosive capsules should be taken from a common ignition current source, in particular in order to keep the effort as low as possible.

F i g. 1 der Zeichnung zeigt in Reihe angeordnete Sprengtrenner, deren aufsprengbare hohle Leiter 1 und 2 zwischen stromleitenden Teilen 3 angeordnet sind. Mit 4 und 5 sind die Stromanschlußleitungen bezeichnet. Um die Anordnung ist ein hier nicht dargestelltes Schutzgehäuse zu denken. In den hohlen Leitern 1 und 2 werden Sprengstoffkapseln untergebracht, von denen hier nur die Zünddrähte 6 und 7 dargestellt sind. Sie sind über die Zündstromleitungen 9, 1O und 11 an eine Zündstromquelle 8 angeschlossen. Bei der Sprengung können hierbei die Zündstromleitungen an das Potential der Stromanschlüsse 4 und 5 geraten, so daß trotz aufgesprengtem Hauptstrompfad die Stromverbindung über die Zündstromleitung weiter besteht. Außerdem kommt an den mit niedriger Spannung betriebenen Zündstromkreise die Potentialdifferenz der aufgesprengten Leiterenden.F i g. 1 of the drawing shows explosive separators arranged in series, their Rupturable hollow conductors 1 and 2 are arranged between electrically conductive parts 3. With 4 and 5, the power supply lines are designated. To the arrangement is a to think of protective housing not shown here. In the hollow ladders 1 and 2 explosives capsules are housed, of which only the ignition wires 6 and 7 are shown. They are connected to an ignition current source via the ignition current lines 9, 10 and 11 8 connected. During the detonation, the ignition current lines can be connected to the Potential of the power connections 4 and 5 advised, so that despite the blown main current path the power connection via the ignition power line continues. Also arrives the ignition circuits operated with low voltage the potential difference of the burst ends of the ladder.

Erfindungsgemäß werden solche Schwierigkeiten durch einen derartigen Aufbau in Reihe geschalteter Sprengtrenner vermieden, daß Sprengstoffkapseln benachbarter Sprengtrenner mit ihren Leitungsanschlüssen für den Zündstrom einander zugekehrt sind. Ein Ausführungsbeispiel dieser Art ist in F i g. 2 dargestellt. Dabei sind die gleichen Bezugsziffern verwendet wie in F i g. 1. Man erkennt ohne weiteres, daß hierbei die Zündstromleitungen bei der Sprengung keineüberbrückung derStromanschlüsse4 und 5 hervorrufen und daß auch die Potentialdifferenz der aufgesprengten Leiterenden nicht in den Zündstromkreis gelangt.According to the invention, such difficulties are caused by such Construction of explosive separators connected in series avoids that explosive capsules are adjacent Explosive separators with their line connections for the ignition current facing each other are. An embodiment of this type is shown in FIG. 2 shown. Are there the same reference numerals are used as in FIG. 1. One recognizes without further ado that in this case the ignition current lines do not bridge the current connections during the detonation4 and 5 and that also the potential difference between the broken conductor ends does not get into the ignition circuit.
