Die Erfindung betrifft ein mehradriges elektrisches Kabel nach dem Oberbegriff des Schutzanspruches 1.The invention relates to a multi-core electrical cable according to the preamble of claim 1.
Durch die deutsche Gebrauchsmusterschrift DT-GH 67 52 466 ist eine ähnliche Leitung für den Niederspannungsbereich bekanntgeworden .By the German utility model DT-GH 67 52 466 is a similar line has become known for the low-voltage sector.
Der Erfindung liegt die Aufgabe zugrunde, ein Kabel zu schaffen, das auch erhöhten Sicherheitsanforderungen gerecht wird, wie sie an Hochspannungskabel im Untertagebetrieb gestellt werden.The invention is based on the object of creating a cable that also meets increased safety requirements, such as those placed on high-voltage cables in underground operations will.
Diese Aufgabe wird durch einen symmetrischen, auf die Einzeladern aufgeteilten Schutzleiter und eine allseitige Überwachung der Ensrgieadern, sowohl im Bereich zwischen den Adern als auch zum Kabelmantel hin, und ein separates Isolatlons-Kontrollsystem gemäß Schutzanspruch 1 gelöst.This task is carried out by a symmetrical protective conductor divided between the individual cores and monitoring from all sides of the ensemble cores, both in the area between the cores and towards the cable sheath, and a separate isolation control system solved according to claim 1 protection.
Die erfindungsgemäße Ausbildung zeichnet sich neben der verbesserten Betriebssicherheit durch eine geringe Betriebskapazität und durch vereinfachte Herstellung aus. Es werden nicht nur die bisherigen Vorteile erhalten, wie Früherkennung von Schäden infolge eindringender Fremdkörper, sondern es werden auch solche Schäden frühzeitig erkannt, die infolge Knickungen, Quetschungen und dergleichen zwischen den Energieadern auftreten; desgleichen wird eindringende Feuchtigkeit durch Ansprechen des Kreises Überwachungsleiter-Schutzleiter schnell erkannt.The inventive training is characterized in addition to the improved Operational safety due to a low operating capacity and simplified manufacture. It won't only get the previous advantages, such as early detection of damage as a result of foreign bodies, but will early detection of damage that occurs as a result of kinks, bruises and the like between the energy cores; In the same way, penetrating moisture is quickly recognized by the monitoring conductor-protective conductor circuit.

Vorteilhafte Ausführungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous embodiments of the invention are set out in the subclaims marked.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, das im folgenden näher beschrieben wird. Die einzige Figur zeigt ein Bergbau-Streckenkabel gemäß der Erfindung im Schnitt.In the drawing, an embodiment of the invention is shown, which is described in more detail below. the single figure shows a mining route cable according to the invention in section.
Das Kabel 1 weist einen zentralen Rontrolleiter 2 auf, der zur Längeleitung einen Litzenleiter 3 und zur Querleitung einen Mantel 4 aus Leitgummi aufweist. Um den Kontrolleiter sind die Außenleiter 5 verseilt, die als Energieleiter aufgebaut sind. Der Außenleiter 5 besteht aus einem mehrdrähtigen, verdichteten Kupferleiter 6, einer extrudierten leitenden Feldsteuerschicht 7, einer Isolierung 8 aus vernetztem Polyäthylen, einer zweiten leitenden Feldsteuerschicht 9, einem einzelkonzentrischen Schutzleiter 10 aus verseilten F.upferdrähten und aus einer metallkaschierten Kunststoffolie 11, deren Metallseite nach außen weist.The cable 1 has a central control ladder 2, which is a stranded conductor 3 for the lengthwise line and for the transverse line has a jacket 4 made of conductive rubber. The outer conductors 5, which are constructed as energy conductors, are stranded around the control conductor are. The outer conductor 5 consists of a multi-stranded, compressed copper conductor 6, an extruded conductive one Field control layer 7, an insulation 8 made of cross-linked polyethylene, a second conductive field control layer 9, a single concentric protective conductor 10 made of stranded copper wires and from a metal-clad plastic film 11, the metal side of which faces outwards.
Die Metallseite der Kunststoffolie 11 dient als Uberwachungsleiterschirm. Die Außenleiter 5 und der Kontrolleiter 2 sind so angeordnet, daß die Metallseite der Kunststoffolie 11 jedes Uberwachungsleiterschirmes mit den beiden anderen uberwachungsleiterschirmen sowie mit dem leitenden Mantel 4 des KontrolL-leiters 2 in elektrisch leitendem Kontakt stehen.The metal side of the plastic film 11 serves as a monitoring conductor screen. The outer conductor 5 and the control conductor 2 are arranged so that the metal side of the plastic film 11 each Monitoring conductor shield with the other two monitoring conductor shields and are in electrically conductive contact with the conductive jacket 4 of the control conductor 2.
Die Zwickel sind mit einer weichplastischen Füllmasse 12 aus Gummi ausgefüllt. Der Kabelmantel besteht aus einem Innenmantel 13 aus PVC, einer Armierung 14 mit einer Lage verzinkter Eisenflachdrähte und mit einer Stahlband-Gegenwendel und aus einem Außenmantel 15 aus PVC.The gussets are filled with a soft plastic filling compound 12 made of rubber. The cable sheath consists of an inner sheath 13 made of PVC, a reinforcement 14 with a layer of galvanized Flat iron wires and with a steel band counter-helix and an outer jacket 15 made of PVC.
Gestrichelt eingezeichnet sind drei zusätzliche Steuerleitungen 16, von deren Art auch nur eine in den Außenzwickeln eingelegt werden kann.Three additional control lines 16 are shown in dashed lines, only one of which is inserted into the outer gusset can be.
