Abstract

Wires with three insulated electric conductors have each conductor (15) encased by an inner conductive layer (16), an insulation (17) lying over it and an outer conductive layer (18) fitted over it. There is also an earth conductor. Each wire has an electric shield (S) applied over the outer conductive layer. A unit made from wires and an earth conductor forms a common sleeve made from insulating material.

Description

Die Erfindung bezieht sich auf eine Starkstromleitung für ortsveränderliche Verbraucher, bestehend aus drei isolierte elektrische Leiter aufweisenden Adern, deren Leiter jeweils von einer inneren Leitschicht, einer darüber liegenden Isolierung und einer über derselben angeordneten äußeren Leitschicht umgeben sind sowie mindestens einem Erdleiter, bei welcher jede Ader einen über der äußeren Leitschicht angebrachten elektrischen Schirm aufweist und bei welcher die Einheit aus Adern und Erdleiter von einem gemeinsamen Mantel aus Isoliermaterial umgeben ist.The invention relates to a power line for portable consumers, consisting of three insulated electrical conductor having cores, the conductors are each surrounded by an inner conductive layer, an overlying insulation and an overlying outer conductive layer and at least one ground conductor, wherein each core a mounted over the outer conductive layer electrical screen and in which the unit of wires and earth conductor is surrounded by a common sheath of insulating material.

Eine solche Starkstromleitung - im folgenden kurz "Leitung" genannt - wird beispielsweise zur Stromversorgung von im Tagebau eingesetzten Maschinen verwendet. Sie muß den Bewegungen der Maschinen ohne Beschädigungsgefahr auf Dauer folgen können, wobei sie ständig wechselnden Biegebeanspruchungen sowie dem rauhen Betrieb eines Tagebaus ausgesetzt ist. Die Leitung kann dabei beispielsweise als entlang einer gegebenen Strecke geführte Schleppleitung oder als trommelbare Leitung eingesetzt werden, die bei der Bewegung einer angeschlossenen Maschine ständig von einer Spule abgewickelt und wieder auf dieselbe aufgewickelt wird. Sie wird während des laufenden Betriebes auf ihre Funktionsfähigkeit überwacht, damit Fehler, insbesondere Beschädigungen, schnellstens festgestellt werden können. Eine Beschädigung der Leitung kann zu einem Phase/Erdschluß mit einer nachfolgenden energiereichen Entladung führen, durch welche Menschen gefährdet werden können. Die Leitung muß daher möglichst unverzüglich von der Spannungsquelle abgetrennt werden. Um das sicherzustellen, sind die Leiter und der Erdleiter der Leitung an eine Überwachungseinheit angeschlossen. Die elektrischen Übergangswiderstände zwischen den Schirmen der Leiter untereinander und zum Erdleiter sind bei bekannten, im Markt erhältlichen Leitungen sehr hoch, so daß bei einem Phasen- oder Erdschluß nur ein relativ niedriger Strom zur Überwachungseinheit fließt. Eine Beschädigung einer Leitung wird daher nur mit Verzögerung und unter Umständen gar nicht festgestellt.Such a power line - in the following called "line" - is used, for example, for power supply of open-pit machinery. It must be able to follow the movements of the machine without risk of damage in the long run, being exposed to constantly changing bending stresses and the harsh operation of an open pit. The line can be used, for example, as along a given route guided trailing cable or as a reelable line, which is constantly unwound during the movement of a connected machine from a spool and wound up again on the same. It is monitored during operation for its functionality, so that errors, especially damage, can be detected as quickly as possible. Damage to the cable can lead to a phase / earth fault with a subsequent high-energy discharge, which can endanger people. The line must therefore be disconnected from the power source as soon as possible. To ensure this, the conductors and the earth conductor of the cable are connected to a monitoring unit. The electrical contact resistance between the shields of the conductors with each other and the ground wire are very high in known, available in the market, so that at a phase or ground fault, only a relatively low current flows to the monitoring unit. Damage to a line is therefore determined only with delay and under certain circumstances not at all.

Eine Starkstromleitung für ortsveränderliche Verbraucher nach dem Oberbegriff des Anspruchs 1 ist aus der US-A-3614300 bekannt.A power line for portable consumer according to the preamble of claim 1 is known from US-A-3614300 known.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Leitung so zu gestalten, daß eine Beschädigung derselben schneller festgestellt werden kann.The invention has for its object to make the line initially described so that damage the same can be detected faster.

Diese Aufgabe wird gemäß Anspruch 1 der Erfindung dadurch gelöst, daß der Schirm jeweils aus einer an der äußeren Leitschicht der Adern anliegenden ersten Lage aus einem elektrisch leitfähigen Kunststoffvlies und einer darüber angeordneten, am Kunststoffvlies anliegenden zweiten Lage aus einem elektrisch leitfähig gummierten Gewebeband besteht.This object is achieved according to claim 1 of the invention in that the screen consists in each case of a voltage applied to the outer conductive layer of the wires first layer of an electrically conductive plastic fleece and arranged above, applied to the plastic nonwoven second layer of an electrically conductive rubberized fabric tape.

Die elektrische Leitfähigkeit des aus den beiden elektrisch leitfähigen Lagen bestehenden Schirms ist gegenüber bekannten Ausführungen so wesentlich erhöht, daß der elektrische Übergangswiderstand zwischen den Schirmen der drei Leiter und zum Erdleiter dieser Leitung etwa um einen Faktor 10 vermindert ist. Er liegt etwa bei 10 Ω oder darunter. Im Falle eines Phase/Erdschlusses fließt ein entsprechend hoher Strom zur Überwachungseinheit, so daß derselbe sofort festgestellt wird und die Leitung schnellstens von der Spannungsquelle abgetrennt werden kann. Außerdem wird durch den niederohmigen Phase/Erdschfuß die mögliche Berührungsspannung so wesentlich reduziert, daß eine Gefährdung von Menschen ausgeschlossen werden kann.The electrical conductivity of the existing of the two electrically conductive layers screen is so much increased over known designs that the electrical contact resistance between the screens of the three conductors and the ground conductor of this line is reduced by a factor of about 10. It is about 10 Ω or less. In the case of a phase / ground fault, a correspondingly high current flows to the monitoring unit, so that the same is detected immediately and the line can be disconnected as quickly as possible from the power source. In addition, the possible contact voltage is so substantially reduced by the low-impedance phase / Erdschfuß that a risk to people can be excluded.

Das Metall, mit welchem das Kunststoffvlies elektrisch leitfähig gemacht ist, wird in bekannter Technik beispielsweise aus der Dampfphase abgeschieden. Es schlägt sich nicht nur auf der äußeren Oberfläche des Vliesmaterials nieder, sondern dringt auch in dasselbe ein und umhüllt dessen innere Fasern, die bekanntermaßen ungeordnet im Vliesmaterial zusammengehalten sind. Das Kunststoffvlies ist dann also "durchdringend" beschichtet. Es hat dadurch eine zwar poröse, aber trotzdem nahezu vollständige geschlossenen Metallschicht.The metal with which the plastic fleece is made electrically conductive, is deposited in a known technique, for example from the vapor phase. It not only settles on the outer surface of the nonwoven material, but also penetrates into it and envelops its inner fibers, which are known to be held together disorderly in the nonwoven material. The plastic fleece is then so "penetrating" coated. It thus has a porous, but almost complete closed metal layer.

In Fig. 1 ist sehr schematisch eine Anordnung mit einer Maschine 1 dargestellt, die in Richtung des Doppelpfeils 2 hin- und her bewegbar ist. Sie ist über eine Starkstromleitung 3 - im folgenden weiter "Leitung 3" genannt - an ein Gerät 4 angeschlossen, in dem sich zumindest eine Spannungsquelle zur Stromversorgung der Maschine 1 und eine Überwachungseinheit 5 befinden, an welche die Leitung 3 angeschlossen ist.In Fig. 1 is very schematically shown an arrangement with a machine 1, which is in the direction of the double arrow 2 back and forth movable. It is connected via a power line 3 - hereinafter referred to as "line 3" - connected to a device 4, in which there are at least one voltage source for powering the machine 1 and a monitoring unit 5, to which the line 3 is connected.

Die Leitung 3 besteht gemäß Fig. 2 beispielsweise aus drei aus isolierten elektrischen Leitern aufgebauten Adern 6, 7 und 8, deren genauerer Aufbau aus Fig. 4 hervorgeht, sowie einem Erdleiter 9. Die Einheit aus Adern 6, 7 und 8 sowie Erdleiter 9 ist von einem Innenmantel 10 aus Isoliermaterial umgeben, der alle äußeren Zwickel der Leitung 3 ausfüllt. Er besteht beispielsweise aus Kautschuk und wird mittels eines Extruders erzeugt. Über dem Innenmantel 10 ist ein äußerer Mantel 11 aus Isoliermaterial angebracht. Er besteht mit Vorteil aus chloriertem Gummi und wird ebenfalls durch Extrusion hergestellt.The line 3 is in accordance Fig. 2 for example, from three constructed of insulated electrical conductors cores 6, 7 and 8, their more detailed structure Fig. 4 The unit of cores 6, 7 and 8 and earth conductor 9 is surrounded by an inner jacket 10 made of insulating material, which fills all the outer gusset of the line 3. It consists for example of rubber and is produced by means of an extruder. Over the inner jacket 10, an outer jacket 11 is attached made of insulating material. It is advantageously made of chlorinated rubber and is also made by extrusion.

Bei der Leitung 3 nach Fig. 3 ist der Erdleiter in drei Teilleiter 12, 13 und 14 aufgeteilt, die in den Zwickeln zwischen den Adern 6, 7 und 8 liegen. Auch bei dieser Ausführungsform der Leitung 3 sind Innenmantel 10 und äußerer Mantel 11 vorhanden. Der Innenmantel 10 füllt auch hier alle äußeren Zwickel der Leitung 3 aus.At the line 3 after Fig. 3 the earth conductor is divided into three sub-conductors 12, 13 and 14, which lie in the interstices between the wires 6, 7 and 8. Also in this embodiment of the line 3 inner shell 10 and outer shell 11 are present. The inner shell 10 also fills all the outer gusset of the line 3 here.

Die Adern 6, 7 und 8 der Leitung 3 bestehen gemäß Fig. 4 jede beispielsweise aus einem Leiter 15, der mit Vorteil als Litzenleiter aus Kupfer ausgeführt ist. Er kann fein- oder feinstdrähtig ausgeführt sein. Dabei können die einzelnen Drähte zusätzlich verzinnt sein. Über dem Leiter 15 ist eine innere Leitschicht 16 angeordnet, die durch Extrusion oder durch Bewicklung mit einem Band erzeugt sein kann. Die innere Leitschicht 16 besteht beispielsweise aus Graphit. Sie ist von einer beispielsweise aus Polyvinylchlorid oder Polyethylen bestehenden Isolierung 17 umgeben, über welcher eine äußere Leitschicht 18 angebracht ist. Die äußere Leitschicht 18 kann auch aus Graphit bestehen und ebenfalls durch Extrusion oder Bebänderung erzeugt sein. Beide Leitschichten können auch aus einem durch den Zusatz von Ruß halbleitend gemachten Isoliermaterial bestehen.The wires 6, 7 and 8 of the line 3 exist according to Fig. 4 each example of a conductor 15, which is advantageously designed as a stranded conductor made of copper. It can be made of fine or very fine wire. The individual wires can also be tinned. Above the conductor 15 is disposed an inner conductive layer 16, which may be produced by extrusion or by winding with a belt. The inner conductive layer 16 is made of graphite, for example. It is surrounded by an existing example of polyvinyl chloride or polyethylene insulation 17, over which an outer conductive layer 18 is attached. The outer conductive layer 18 can also be made of graphite and also be produced by extrusion or harness. Both conductive layers can also consist of an insulating material made semiconductive by the addition of carbon black.

Über der äußeren Leitschicht 18 ist ein elektrisch wirksamer Schirm S angebracht, der aus einer an derselben anliegenden ersten Lage 19 und einer dieselbe spaltfrei umgebenden zweiten Lage 20 aufgebaut ist. Die beiden Lagen des Schirms S sind in Fig. 4 durch eine gestrichelt eingezeichnete Linie als zwei unterschiedliche, voneinander getrennte Schichten angedeutet.Over the outer conductive layer 18, an electrically effective screen S is mounted, which is constructed of a first layer adjacent to the same 19 and a second layer 20 surrounding the same gap-free. The two layers of the screen S are in Fig. 4 indicated by a dashed line as two different, separate layers.

Die erste Lage 19 besteht aus einem elektrisch leitfähigen Kunststoffvlies, das längseinlaufend um die äußere Leitschicht 18 herumgeformt oder um dieselbe mit einer Überlappung von beispielsweise 15 % herumgewickelt sein kann, wobei jeweils eine rundum geschlossene Hülle erzeugt wird. Das Kunststoffvlies kann beispielsweise aus Nylon oder aus anderen geeigneten Kunststoffen bestehen. Seine Wandstärke bzw. Dicke liegt vorzugsweise zwischen 80 µm und 150 µm. Für seine Metallisierung wird ein elektrisch gut leitendes Metall verwendet, insbesondere Kupfer. Das Kupfer bzw. ein anderes elektrisch gut leitendes Metall wird für die Metallisierung in den schmelzflüssigen Zustand überführt und aus der Dampfphase auf dem Vliesmaterial abgeschieden. Dabei dringt das Kupfer auch in das Vliesmaterial ein und umhüllt die dort befindlichen, ungeordnet zusammengehaltenen Fasern. Insgesamt wird auf und in dem Kunststoffvlies eine zwar poröse, aber nahezu geschlossene Kupferschicht erzeugt. Der elektrische Widerstand des Kunststoffvlieses ist kleiner als 0,5 Ω.The first layer 19 is made of an electrically conductive plastic fleece which may be longitudinally formed around the outer conductive layer 18 or wrapped around it with an overlap of, for example, 15%, each creating a completely closed sheath. The plastic fleece may for example consist of nylon or other suitable plastics. Its wall thickness or thickness is preferably between 80 .mu.m and 150 .mu.m. For its metallization, a good electrically conductive metal is used, in particular copper. The copper or other good electrical conductivity metal is transferred to the molten state for the metallization and deposited from the vapor phase on the nonwoven material. The copper also penetrates into the nonwoven material and wraps around the fibers held there disorderly. Overall, a porous, but almost closed copper layer is produced on and in the plastic fleece. The electrical resistance of the plastic fleece is less than 0.5 Ω.

Die zweite Lage 20 besteht beispielsweise aus einem elektrisch leitend gummierten Gewebeband auf der Basis von Zellwolle. Das Gewebeband wird mit Vorteil beidseitig elektrisch leitend graphitiert. Es hat einen Oberflächenwiderstand von maximal 400 Ω. Zur Herstellung der Lage 20 wird ein entsprechendes Band mit einer vorzugsweise zwischen 250 µm und 320 µm liegenden Dicke mit einer Überlappung von beispielsweise 15 % um die erste Lage 19 herumgewickelt. Der Schirm S hat insgesamt eine Wandstärke, die mit Vorteil etwa bei 0,4 mm liegt.The second layer 20 consists for example of an electrically conductive rubberized fabric tape based on rayon. The fabric tape is advantageously graphitized on both sides electrically conductive graphite. It has a maximum surface resistance of 400 Ω. To produce the layer 20, a corresponding strip having a thickness preferably between 250 μm and 320 μm is wound around the first layer 19 with an overlap of, for example, 15%. The screen S has a total wall thickness, which is advantageously about 0.4 mm.

Der Erdleiter 9 ist mit Vorteil als ein in Form einer Litze aus Kupferdrähten bestehender Strang ausgeführt. Er kann in vorteilhafter Ausführungsform von einer Schicht aus einem elektrisch leitfähig gummierten Gewebeband umgeben sein, das in gleicher Weise ausgeführt sein kann, wie das Gewebeband der Lage 20 des Schirms S.The earth conductor 9 is advantageously designed as a strand consisting of copper wires in the form of a strand. It may be surrounded in an advantageous embodiment of a layer of an electrically conductive rubberized fabric tape, which may be carried out in the same manner as the fabric tape of the layer 20 of the screen S.
