Die Erfindung bezieht sich auf ein Hochspannungskabel mit integrierten optischen Übertragungselementen, die im Inneren von mindestens einem nichtmetallischen, rohrartigen oder schlauchartigen Element eingeschlossen und von mindestens einer Lage von zugfesten Verseilelementen sowie von mindestens einer Lage von elektrisch leitenden Verseilelementen umgeben sind.The invention relates to a high-voltage cable with integrated optical transmission elements which are enclosed inside at least one non-metallic, tubular or hose-like element and are surrounded by at least one layer of tensile stranding elements and at least one layer of electrically conductive stranding elements.
Zur Übertragung von Meßwerten und Steuersignalen in Hochspannungsnetzen werden optische Übertragungselemente verwendet, die in die Phasenseilkabel integriert sein können. Dabei können die optischen Übertragungselemente zu einer Bündelader zusammengefaßt sein, die innerhalb des Kabels von einem oder mehreren Verseilverbänden aus gut leitenden und/oder zugfesten Metalldrähten umgeben ist. Ein derartiges Hochspannungskabel ist z. B. aus der DE-OS 31 A6 9kl bekannt. Aus dieser Druckschrift ist insbesondere bekannt, die optischen Übertragungselemente durch ein schlauchartiges Element aus einem Kunststoff zu umgeben. Die dort vorgeschlagenen Materialien sind allerdings nicht im genügendem Maße temperaturstabil.Optical transmission elements, which can be integrated in the phase cable, are used to transmit measured values and control signals in high-voltage networks. The optical transmission elements can be combined to form a loose tube, which is surrounded within the cable by one or more stranding assemblies made of highly conductive and / or tensile metal wires. Such a high voltage cable is e.g. B. known from DE-OS 31 A6 9kl. From this document it is known in particular to surround the optical transmission elements by a hose-like element made of a plastic. However, the materials proposed there are not sufficiently temperature-stable.
Der Erfindung liegt daher die Aufgabe zugrunde, einThe invention is therefore based on the object
Hochspannungskabel zu schaffen, das die genannten Nachteile vermeidet und bei dem die innen liegenden optischen Übertragungselemente vor Beschädigungen geschützt sind.To create high-voltage cable that avoids the disadvantages mentioned and in which the internal optical transmission elements are protected from damage.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die optischen Übertragungselemente von einem inneren schlauchartigen Element umgeben sind, welches aus einem temperaturbeständigen Spritzgu߬ werkstoff, insbesondere aus einem aromatisch substituierten Polyamid, einem Polykarbonat oder einem Polyätherymid besteht und daß das innere schlauchartige Element von einem äußeren schlauchartigen Element umgeben ist, das aus einem höchst- molekularen Polyester besteht.The object is achieved in that the optical transmission elements are surrounded by an inner tube-like element which consists of a temperature-resistant injection molding material, in particular an aromatically substituted polyamide, a polycarbonate or a polyether amide, and in that the inner tube-like element is surrounded by an outer tube-like element Element is surrounded, which consists of a molecular polyester.
Der besondere Vorteil der Erfindung besteht darin, daß die optischen Übertragungselemente durch das innere schlauchartige Element vor hohen Temperaturen geschützt werden, die im Kurzschlußstromfall in dem Hochspannungskabel herschen. Außerdem dichtet das Innere schlauchartige Element die optischen Übertragungselemente gegen von außen eindringende Feuchtigkeit ab. Das innere schlauchartige Element selbst ist durch die Materialauswahl sehr temperaturstabil.The particular advantage of the invention is that the optical transmission elements are protected by the inner tube-like element from high temperatures which occur in the high-voltage cable in the event of a short-circuit current. In addition, the inner tube-like element seals the optical transmission elements against moisture penetrating from the outside. The inner tube-like element itself is very temperature-stable due to the choice of material.
Das innere schlauchartige Element ist von einem äußeren schlauchartigen Element aus einem höchstmolekularen Polyester umgeben, das das innere schlauchartige Element vor schädigenden Einflüssen schützt, insbesondere von dem Kontakt mit spannungs- rißauslösenden Mitteln wie z. B. UV-Strahlung, Regenwasser oder Lösungsmitteln. Der höchstmolekulare Polyester, aus dem das schlauchartige Element besteht, ist seinerseits nicht anfällig gegen spannungsrißauslösende Mittel.The inner tube-like element is surrounded by an outer tube-like element made of a high molecular weight polyester, which protects the inner tube-like element from damaging influences, in particular from contact with agents that cause stress cracks, such as. B. UV radiation, rainwater or solvents. The high molecular weight polyester from which the tubular element is made is in turn not susceptible to agents that cause stress cracking.
Die Erfindung kann vorteilhaft dadurch ausgestaltet werden, daß der Spritzgußwerkstoff ein Molekulargewicht zwischen 30 000 AME und 50 000 AME aufweist.The invention can advantageously be designed in that the injection molding material has a molecular weight between 30,000 AME and 50,000 AME.
Der Vorteil dieser Ausgestaltung der Erfindung liegt darin, daß die entsprechenden Werkstoffe noch mit einem vertretbaren Aufwand verarbeitbar sind, wobei durch das hohe Molekular¬ gewicht eine große mechanische und Temperaturstabilität gewährleistet sind.The advantage of this embodiment of the invention lies in the fact that the corresponding materials can still be processed at a reasonable cost, the high molecular weight ensuring high mechanical and temperature stability.
Eine besondere Ausgestaltung der Erfindung sieht vor, daß das äußere schlauchartige Element von einem kalibrierten Mantel aus einem temperaturbeständigen Material, insbesondere aus einem Fluorpolymeren besteht.A special embodiment of the invention provides that the outer tubular element consists of a calibrated jacket made of a temperature-resistant material, in particular of a fluoropolymer.
Durch den Mantel wird das äußere schlauchartige Element vor Verletzungen durch die Verseilelemente geschützt.The outer tubular element is provided by the jacket Injuries protected by the stranding elements.
Eine weitere Ausgestaltung der Erfindung sieht vor, daß die zugfesten Verseilelemente ein querdruckfestes Gewölbe bilden, das die optischen Übertragungselemente mit den schlauchartigen nichtmetallischen Elementen direkt umgibt.A further embodiment of the invention provides that the tensile stranding elements form a cross-pressure-resistant vault which directly surrounds the optical transmission elements with the tubular, non-metallic elements.
Dadurch, daß die zugfesten Verseilelemente ein querdruckfestes Gewölbe bilden, wird insbesondere an den Stellen, an denen das Hochspannungskabel in Abspannklemmen befestigt ist, vermieden, daß die optischen Übertragungselemente gequetscht und dadurch beschädigt werden.The fact that the tensile stranding elements form a cross-pressure-resistant vault prevents the optical transmission elements from being squashed and thereby damaged, particularly at the points at which the high-voltage cable is fastened in tensioning clamps.
Weiterhin kann die Erfindung dadurch ausgestaltet werden, daß die zugfesten Verseilelemente aus Stahldraht bestehen.Furthermore, the invention can be designed in that the tensile stranding elements consist of steel wire.
Die Ausführung der zugfesten Verseilelemente in Stahldraht bewirkt einerseits, daß durch die mechanische Stabilität der Stahldrähte des querdruckfeste Gewölbe stabil wird und andererseits, daß durch die geringe Wärmeleitfähigkeit derThe execution of the tensile stranding elements in steel wire causes on the one hand that the mechanical stability of the steel wires of the cross-pressure-resistant vault is stable and on the other hand that due to the low thermal conductivity of the
Stahldrähte eine Hochtemperaturwelle, die im Kurzschlußfall in den leitenden Drähten des Hochspannungskabels erzeugt wird, auf dem Weg in das Innere des Kabels zu den optischen Übertragungs¬ elementen hin gedämpft wird.Steel wires a high-temperature wave, which is generated in the event of a short circuit in the conductive wires of the high-voltage cable, is attenuated on the way into the interior of the cable to the optical transmission elements.
Weiterhin kann die Erfindung dadurch ausgestaltet werden, daß die Lage der zugfesten Verseilelemente von mindestens einer Lage von Verseilelementen aus Aluminium oder einer gut leitenden Aluminiumlegierung umgeben ist.Furthermore, the invention can be embodied in that the position of the tensile stranding elements is surrounded by at least one layer of stranding elements made of aluminum or a highly conductive aluminum alloy.
Der besondere Vorteil dieser Ausgestaltung der Erfindung liegt darin, daß die Aluminiumdrähte als gute Leiter relativ kosten¬ günstig herzustellen und technisch leicht zu verarbeiten sind.The particular advantage of this embodiment of the invention is that the aluminum wires, as good conductors, are relatively inexpensive to manufacture and technically easy to process.
Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, daß die optischen Übertragungselemente im Inneren des inneren schlauchartigen Elementes in eine vernetzende Silikonmasse längswasserdicht eingebettet sind.Another advantageous embodiment of the invention provides that the optical transmission elements inside the inner tube-like element are embedded in a cross-linking silicone mass longitudinally watertight.
Durch die längswasserdichte Einbettung in die Silikonmasse bleiben die optischen Übertragungselemente auch im Falle der Verletzung der nichtmetallischen schlauchartigen Elemente, von denen sie umgeben sind, von größerem Schaden durch das Eindringen von Wasser verschont. Die vernetzende Silikonmasse ist insbesondere sehr alterungsbeständig.Due to the longitudinally watertight embedding in the silicone mass, the optical transmission elements are spared greater damage due to the penetration of water even in the event of damage to the non-metallic tubular elements which surround them. The cross-linking silicone mass is particularly very resistant to aging.
Die .Erfindung wird anhand eines Ausführungsbeispiels in einer Zeichnung gezeigt und nachfolgend beschrieben.The invention is shown using an exemplary embodiment in a drawing and described below.
Die einzige Figur zeigt ein Hochspannungskabel im Querschnitt.The only figure shows a high-voltage cable in cross section.
Im Zentrum des Hochspannungskabels sind die optischen Übertragungselemente 1 angeordnet. Diese können aus allen bekannten Arten von Lichtwellenleitern bestehen. Sie sind in eine vernetzende Silikonmasse 7 eingebettet. Die Einbettung in diese Masse garantiert, daß eindringendes Wasser sich nicht längs der optischen Übertragungselemente ausbreiten kann. Die vernetzende Silikonmasse 7 ist sehr alterungsbeständig. Um die Silikonmasse 7 herum ist ein inneres schlauchformiges Element 2 aus einem temperaturbeständigen Spritzgußwerkstoff angeordnet. Dieser Spitzgußwerkstoff kann aus einem aromatisch substi¬ tuierten Polyamid bestehen, das beispielsweise unter dem Namen Cerilamid TR 55 von der Firma Ems Chemie vertrieben wird, oder aus einem Polykarbonat, wie es beispielsweise unter dem Namen Makrolon 3118 von der Firma Bayer vertrieben wird, oder aus einem Polyätherymid wie es beispielsweise von der Firma General Electric unter dem Namen Ulte 1000 vertrieben wird.The optical transmission elements 1 are arranged in the center of the high-voltage cable. These can consist of all known types of optical fibers. They are embedded in a cross-linking silicone mass 7. The embedding in this mass guarantees that penetrating water cannot spread along the optical transmission elements. The crosslinking silicone mass 7 is very resistant to aging. An inner tubular element 2 made of a temperature-resistant injection molding material is arranged around the silicone compound 7. This injection molding material can consist of an aromatically substituted polyamide, which is marketed, for example, under the name Cerilamid TR 55 by Ems Chemie, or of a polycarbonate, such as is marketed for example under the name Makrolon 3118 by Bayer, or from a polyether amide such as that sold by General Electric under the name Ulte 1000.
Dieses innere schlauchartige Element 2 ist seinerseits von einem spannungsrißfesten äußeren schlauchartigen Element 3 umgeben, das relativ dünnwandig ist und möglichst gut mit dem inneren schlauchartigen Element 2 abbindet. Dieses Element 3 besteht aus einem höchstmolekularen Polyester. Ein solcherThis inner tube-like element 2 is in turn surrounded by an outer tube-like element 3 that is resistant to stress cracking, which is relatively thin-walled and binds as well as possible to the inner tube-like element 2. This element 3 consists of a high molecular weight polyester. Such a
Polyester wird beispielsweise unter dem Namen Vertadin 3000 von der Firma Hüls angeboten. Die spannungsrißfeste Deckschicht 3, die das äußere schlauchartige Element 3 bildet, wird ihrerseits durch einen kalibrierten Mantel 4 aus einem temperatur¬ beständigen Material, insbesondere aus einem Fluorpolymeren vor Verletzungen durch die aufgeseilten Stahldrähte 5 geschützt. Die Lage der Stahldrähte 5, die auf den Verseilkern mit den optischen Übertragungselementen aufgeseilt ist, muß zu mehr als 99 % geschlossen sein um ein querdruckfestes Gewölbe bilden zu können. Auf die Lage aus Stahldrähten 5 sind zwei Lagen aus Aluminiumdrähten 6 aufgeseilt. Die äußeren Verseillageπ aus Aluminiumdrähten müssen sich nach außen um 2 bis 3 % öffnen um die mechanische Ankopplung der Abspann- und Tragganituren an die Innenlage der Stahldrähte 5 zu garantieren. For example, polyester is offered by the Hüls company under the name Vertadin 3000. The stress-crack-resistant cover layer 3, which forms the outer tubular element 3, is in turn protected by a calibrated jacket 4 made of a temperature-resistant material, in particular a fluoropolymer, from injuries caused by the stranded steel wires 5. The position of the steel wires 5, which is stranded on the stranding core with the optical transmission elements, must be closed to more than 99% in order to be able to form a cross-pressure-resistant vault. Two layers of aluminum wires 6 are roped onto the layer of steel wires 5. The outer Verseillageπ made of aluminum wires must open to the outside by 2 to 3% to guarantee the mechanical coupling of the guy and support structures to the inner layer of the steel wires 5.
