Description

Die Erfindung betrifft eine Leiterverbindung zum Verbinden von Starkstromkabeln mit Teilstücken, welche zur Leiterver­ bindung verbunden werden.The invention relates to a conductor connection for connecting of power cables with sections that are used to connect conductors bond.

Beim Betreiben von Starkstromkabeln kann es durch verschie­ dene Einflüsse zu Erdschlüssen oder Kurzschlüssen kommen, die zu einer Beschädigung des Kabels führen. Die Fehler­ stelle ist im allgemeinen örtlich begrenzt und hat in der Regel eine Länge von weniger als 1 Meter bzw. nur eine Länge von Zentimetern.When operating power cables, it can be caused by various whose influences lead to earth faults or short circuits, that damage the cable. The mistakes position is generally local and has in the Usually a length of less than 1 meter or only one length of centimeters.

Der Erfindung liegt die Aufgabe zugrunde, eine Lösung anzu­ geben die bei Starkstromkabeln eine schnelle und einfache Reparatur einer Fehlerstelle ermöglicht, welche durch Erd­ schlüsse oder durch Kurzschlüsse hervorgerufen wird. Diese Aufgabe wird durch eine Leiterverbindung der oben genannten Art mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.The invention has for its object to provide a solution give a quick and easy with power cables Repair of a fault location, which is caused by earth short-circuits or short-circuits. These Task is accomplished through a wire connection of the above Kind solved with the characterizing features of claim 1.

Die Erfindung wird im folgenden an einem Ausführungsbeispiel erläutert.The invention is based on an embodiment explained.

Die Fig. 1 zeigt ein schadhaftes Starkstromkabel, welches an der Stelle 1 durchgeschlagen ist. Die beschädigte Stelle hat beispielsweise eine Länge von 10 cm. Wie die Fig. 1 zeigt, sind beim Durchschlag alle Aufbauelemente des Kabels wie der Leiter 2, die innere Leitschicht 3, die Isolierung 4 die äußere Leitschicht 5, die Schirmdrähte 6 und der Außen­ mantel 7 beschädigt worden. Fig. 1 shows a defective power cable, which is broken through at point 1 . The damaged area has a length of 10 cm, for example. As shown in FIG. 1, all structural elements of the cable such as the conductor 2 , the inner conductive layer 3 , the insulation 4, the outer conductive layer 5 , the shield wires 6 and the outer jacket 7 have been damaged during breakdown.

Um die schadhafte Stelle reparieren zu können, wird das be­ schädigte Kabelteil herausgeschnitten. Das Resultat zeigt die Fig. 2, nämlich zwei Kabelenden 8 und 9, die voneinander getrennt sind, wobei der Abstand der beiden Kabelenden 8 und 9 der Länge desjenigen Kabelteils entspricht, welches wegen seiner Beschädigung herausgetrennt werden mußte. Da die Starkstromkabel ja fest (in der Erde) angeordnet sind, kann der Abstand zwischen den beiden Kabelenden 8 und 9 (im Reparaturbereich) durch eine Leiterverbindung gemäß der Er­ findung überbrückt werden.In order to repair the damaged area, the damaged cable part is cut out. The result is shown in FIG. 2, namely two cable ends 8 and 9 which are separated from one another, the distance between the two cable ends 8 and 9 corresponding to the length of the cable part which had to be removed because of its damage. Since the power cables are fixed (in the ground), the distance between the two cable ends 8 and 9 (in the repair area) can be bridged by a conductor connection according to the invention.

Um die Leiterverbindung zwischen den beiden Kabelenden 8 und 9 herstellen zu können, werden die Kabelenden 8 und 9 gemäß der Fig. 3 für die Reparatur vorbereitet. Dabei wird gemäß der Fig. 3 ein Teil der Leiterisolierung 4 und der Leitschichten 3 und 5, Leitschicht 3 ist nicht gezeich­ net, entfernt, und zwar derart, daß die Leiter 2 der beiden Kabel an ihren Enden freigelegt werden. Die in diesem Be­ reich befindlichen Schirmdrähte 6 werden gemäß der Fig. 3 zurückgebogen.In order to be able to establish the conductor connection between the two cable ends 8 and 9 , the cable ends 8 and 9 are prepared according to FIG. 3 for the repair. In this case, 3 a part of the conductor insulation 4 and the conductive layers according to the Fig. 3 and 5, the conductive layer 3 is not net Drawn removed in such a manner that the conductor 2 of the two cables are exposed at their ends. The shield wires 6 located in this area are bent back according to FIG. 3.

Beim Ausführungsbeispiel erfolgt die Überbrückung im Repara­ turbereich und damit die Verbindung der freigelegten Leiter­ teile durch eine Steckverbindung. Zur Herstellung der Steck­ verbindung werden gemäß der Fig. 4 die beiden Steckverbin­ dungsteile 10 und 11 der Reparaturmuffe mit ihrem einen Ende auf die freigelegten Leiterenden 2 aufgepreßt. Die Länge der Steckverbindungsteile (10, 11) ist so bemessen, daß das herausgeschnittene Kabelteil überbrückt wird. Im Ausführungs­ beispiel ist gemäß der Fig. 4 das Steckerteil 11 der Steck­ verbindung länger bemessen als die Buchse 10.In the embodiment, the bridging takes place in the repair area and thus the connection of the exposed conductor parts by a plug connection. To produce the plug connection, the two plug connection parts 10 and 11 of the repair sleeve are pressed with one end onto the exposed conductor ends 2 according to FIG. 4. The length of the connector parts ( 10 , 11 ) is dimensioned so that the cable part cut out is bridged. In the execution example, the plug part 11 is shown in FIG. 4 of the connectors dimensioned longer than the bush 10.

Bevor die beiden Teile 10 und 11 der Steckverbindung zusam­ mengesteckt werden, wird eine Isoliermuffe 12 gemäß der Fig. 5 über eines der beiden vorbereiteten Kabelenden ge­ schoben. Im Ausführungsbeispiel der Fig. 5 wird die Isolier­ muffe 12 auf das Kabelende mit dem Steckerteil 11 aufgescho­ ben. Danach wird gemäß der Fig. 6 das Kabelende mit der Buchse 10 in die Muffe 12 eingeschoben, und zwar soweit, bis der Stecker 11 in der Buchse 10 einrastet. Das Einrasten des Steckers 11 in der Buchse 10 bewirkt, daß die beiden Leiter­ enden miteinander elektrisch verbunden sind. Before the two parts 10 and 11 of the connector are plugged together, an insulating sleeve 12 is pushed according to FIG. 5 ge over one of the two prepared cable ends. In the embodiment of FIG. 5, the insulating sleeve 12 is pushed onto the cable end with the plug part 11 . Thereafter, the Fig the cable end is in accordance. 6 inserted with the sleeve 10 in the sleeve 12, and to such an extent engage into the socket 10 to the plug 11. The engagement of the plug 11 in the socket 10 causes the two ends to be electrically connected to one another.

Zur Abschirmung der Isoliermuffe wird gemäß der Fig. 7 ein metallischer Gewebeschlauch 13 (z. B. aus Kupfer) über die Verbindungsstelle geschoben. Mit diesem Gewebeschlauch 13 werden die Schirmdrähte 6 elektrisch leitend verbunden. Dies geschieht dadurch, daß die Schirmdrahtenden in beidseitig vorhandene, mit dem Gewebeschlauch 13 verbundene Schirmver­ binder 14 und 15 eingeführt und mit diesen verpreßt werden.To shield the insulating sleeve, a metallic fabric hose 13 (e.g. made of copper) is pushed over the connection point according to FIG. 7. With this fabric tube 13 , the shield wires 6 are connected in an electrically conductive manner. This is done in that the shield wire ends are inserted in the bilateral, connected to the fabric hose 13 Schirmver binder 14 and 15 and pressed with these.

Schließlich wird noch gemäß der Fig. 8 ein Schrumpf­ schlauch 17 über den Muffenkörper geschoben und durch eine Wärmebehandlung aufgeschrumpft. Die Leiterverbindung ist damit fertiggestellt.Finally, according to FIG. 8, a shrink tube 17 is pushed over the sleeve body and shrunk on by a heat treatment. The conductor connection is now complete.
