Description
Mehradrige, bewegliche Starkstromleitung, die in den Zwickelräumen zwischen den Hauptleitern längsdehnbare Hilfsleiter enthält Die Erfindung betrifft eine mehradrige, bewegliche Starkstromleitung, die in den Zwickelräumen zwischen den Hauptleitern längsdehnbare Hilfsleiter enthält, die von einer Umhüllung von hoher mechanischer Fertigkeit mit Spiel umgeben sind. Derartige längsdehnbare Hilfsleiter werden insbesondere zusätzlich zu den Hauptleitern in Schrämleitungen, wie sie für den Bergbau unter Tage Verwendung finden, eingelegt und dienen zur Weiterleitung von Steuerströmen oder zur Verbesserung des Längswiderstandes von Leitgummischichten.Multi-core, movable power line, which is in the crotch spaces between the main conductors contains longitudinally expandable auxiliary conductors. The invention relates to a multi-core, movable power line, which is in the interstices between the main ladder contains elongated auxiliary ladder, which is covered by a high mechanical skill are surrounded by play. Such elongated auxiliary ladder are in particular in addition to the main ladders in sloping lines, as they are for found underground mining use, inserted and serve for forwarding of control currents or to improve the series resistance of conductive rubber layers.
Es hat sich gezeigt, daß diese im Verhältnis zu den Hauptadern relativ dünnen Leiter bei dem muhen Betrieb leicht brechen. Als Grund hierfür wurde die mangelhafte Dehnungsfähigkeit der Leiter angesehen, die ihnen nicht gestatte, bei den unvermeidlich starken Biegungen und Zugbeanspruchungen der Leitung genügend nachzugeben und vor allem nach dem Aufhören der Beanspruchung in den alten Zustand zurückzukehren. Bei Verwendung hochdehnbarer Leiter, z. B. in Form einer Wendel oder leicht gewellter Drähte, wurde zwar eine gewisse Verbesserung erzielt, jedoch traten immer noch unerwünscht häufig Leitungsbrüche auf.It has been shown that this is relative in relation to the main arteries Break the thin conductor easily during low operation. The reason for this was the Inadequate elongation of the ladder is considered, which does not allow them to sufficient for the inevitable strong bends and tensile stresses on the cable to give in and especially after the strain has ceased to return to the old state to return. When using highly expandable conductors, e.g. B. in the form of a helix or slightly corrugated wires, some improvement has been achieved, however line breaks were still undesirably frequent.
Die Erfindung geht von der Erkenntnis aus, daß ein Hilfsleiter für den genannten Zweck nicht nur gute Dehnbarkeit, sondern auch genügende Widerstandsfähigkeit gegenüber radialen Beanspruchungen besitzen muß.The invention is based on the knowledge that an auxiliary conductor for the stated purpose not only good elasticity, but also sufficient resistance must have against radial loads.
Es sind zwar schon mehradrige, bewegliche Leitungen bekannt, deren Hauptleiter lose in Isolierschläuchen liegen, wobei die Isolierschläuche mit Einlagen aus Metall in Form von Spiralmetallschläuchen ausgeführt sein können. Eine derartige Leitung wäre aber als Hilfsleiter für den genannten Zweck nicht verwendbar, weil die lose Lage des Leiters in der Isolierhülle allein ihm nicht die nötige Dehnbarkeit gibt.There are already multi-core, movable lines known whose Main conductors lie loosely in insulating tubes, the insulating tubes with inserts can be made of metal in the form of spiral metal hoses. Such a one However, the line could not be used as an auxiliary conductor for the stated purpose, because the loose position of the conductor in the insulating sleeve alone does not give it the necessary elasticity gives.
Ferner sind längsdehnbare, bewegliche Leiter bekannt, die aus zwei konzentrischen Metallgeflechten bestehen, zwischen denen Gummistränge verlaufen. Auch diese Leiter sind wegen der eingelegten Gummistränge in ihrer Dehnungsfähigkeit etwas beschränkt, insbesondere sind sie aber als Hilfleiter nicht zu verwenden, weil es ihnen an der nötigen Festigkeit gegenüber radialen Beanspruchungen mangelt.Furthermore, elongate, movable conductors are known, which consist of two There are concentric metal braids with strands of rubber running between them. These conductors are also stretchable because of the inserted rubber strands somewhat limited, but in particular they are not to be used as an auxiliary ladder, because they lack the necessary strength against radial loads.
Die genannten Nachteile sind bei der neuen Starkstromleitung mit längsdehnbaren Hilfsleitern dadurch vermieden, daß erfindungsgemäß die Umhüllung aus einem rohrförmigen Stahldrahtgeflecht besteht und der Hilfsleiter als elektrisch gutleitender Drahtschlauch ausgebildet ist. Zweckmäßig besteht der Hilfsleiter aus einem Kupfergeflecht.The disadvantages mentioned are with the new power line with longitudinally expandable Auxiliary ladders avoided in that, according to the invention, the sheathing consists of a tubular Steel wire mesh and the auxiliary conductor as an electrically good conductive wire hose is trained. The auxiliary conductor expediently consists of a copper braid.
Ein derartiger Leiter besitzt genügende Festigkeit gegenüber radialen Beanspruchungen, da diese die äußere Hülle aus hochfestem Material auffängt. Die innere Hülle aus gutleitendem Material, also der eigentliche Hilfsleiter, ist sehr gut dehnbar, weil sie weder einen Kern enthält noch zwischen ihr und der äußeren Hülle Stränge verlaufen, die bei Längsdehnung Widerstand bieten würden:.Such a conductor has sufficient strength against radial Stresses, as this absorbs the outer shell made of high-strength material. the inner shell made of highly conductive material, so the actual auxiliary conductor, is very good elasticity because it contains neither a core nor between it and the outer one Sheath strands run that would offer resistance if stretched longitudinally:
An Hand der Abb. 1 und 2, die ein Ausführungsbeispiel der Erfindung darstellen, seien Einzelheiten näher erläutert.With reference to Figs. 1 and 2, an embodiment of the invention represent, details are explained in more detail.
Abb. 1 zeigt einen Hilfsleiter in Seitenansicht. Er ist an einem Ende abgestuft gezeichnet. In. dem mit 1 bezeichneten äußeren schlauchartigen Stahldrahtgeflecht sitzt locker ein elektrisch gutleitender Drahtschlauch Z, z. B. aus Kupfer. Der in dieser Weise aufgebaute Hilfsleiter kann mit einer isolierenden oder leitfähigen Hülle 3 aus elastischem Stoff umgeben sein.Fig. 1 shows an auxiliary ladder in side view. He's at one end drawn in steps. In. the designated with 1 outer tubular steel wire mesh sits loosely an electrically good conductive wire hose Z, z. B. made of copper. Of the Auxiliary conductor constructed in this way can be provided with an insulating or conductive one Sheath 3 be surrounded by elastic material.
Die Abb. 2 gibt eine mehradrige, bewegliche Starkstromleitung mit Hilfsleitern nach der Erfindung im Querschnitt wieder. Um einen Kern 4, der einen Hilfsleiter 5 enthält, sind vier Hauptadern 6 verseilt, die mit einem Gummiband 7, einem Innenmantel 8 und einen Außenmantel 9 umgeben sind. In den vier Zwickelräumen 10 sind ebenfalls Hilfsleiter 5 untergebracht. Je nach dem Verwendungszweck können die einzelnen Adern und Hilfsleiter mit isolierendem oder leitfähigem Gummi umgeben sein. Ebenso kann das Material für den Kern und das Gummiband-isolierend oder leitend sein.Fig. 2 shows a multi-core, movable power line Auxiliary ladders according to the invention in cross section again. To a core 4, the one Contains auxiliary conductor 5, four main cores 6 are stranded with a rubber band 7, an inner jacket 8 and an outer jacket 9 are surrounded. In the four gusset spaces 10 auxiliary conductors 5 are also accommodated. Depending on the intended use, you can the Surround individual wires and auxiliary conductors with insulating or conductive rubber be. Likewise, the material for the core and the rubber band can be insulating or conductive be.
