Description
Die Erfindung betrifft einen Kabelstrumpf und eine Windkraftanlage mit einem Kabelstrumpf.The invention relates to a cable stocking and a wind turbine with a cable stocking.
Kabelstrümpfe der in Rede stehenden Art dienen zum Einziehen und/oder Befestigen von Kabeln. Sie weisen ein Geflecht aus Drähten und/oder Drahtseilen auf. Kabelstrümpfe sind dazu ausgebildet, einen Abschnitt eines Kabels zu umgeben. Das Geflecht ist so gestaltet, dass es sich um das Kabel zusammenzieht, wenn Zugkräfte von dem Kabel in das Geflecht eingeleitet werden. Das Zusammenziehen des Geflechts resultiert hierbei aus dessen Maschenstruktur. Werden Kräfte vom Kabel in das Geflecht eingeleitet, so längen sich aufgrund der Reibung zwischen dem Kabel und dem Geflecht die Maschen in Längsrichtung des Kabels. Dies hat zur Folge, dass die sich Maschen in Umfangsrichtung des Kabels um das Kabel zusammenziehen.Cable stockings of the type in question are used for pulling and / or attaching cables. They have a network of wires and / or wire ropes. Cable socks are configured to surround a portion of a cable. The braid is configured to contract around the cable as tensile forces from the cable are introduced into the braid. The contraction of the mesh results from its mesh structure. When forces are introduced from the cable into the braid, the stitches in the longitudinal direction of the cable lengthen due to the friction between the cable and the braid. As a result, the stitches in the circumferential direction of the cable contract around the cable.
Ein Kabelstrumpf ist beispielsweise in dem deutschen Gebrauchsmuster G 92 04 780.7 beschrieben.A cable stocking is described for example in German Utility Model G 92 04 780.7.
Kabelstrümpfe weisen jedoch den Nachteil auf, dass es durch die Reibung zwischen dem Geflecht und der Isolation des Kabels und dem daraus folgenden Abrieb der Isolation zu einer Beschädigung des Kabels kommen kann. Dies kann im schlimmsten Fall dazu führen, dass es zum Versagen der Isolation kommt. In diesem Fall besteht die Gefahr von Kurzschlüssen und der Kabelstrumpf und gegebenenfalls weitere, mit dem Kabelstrumpf verbundene Gegenstände können unter Spannung gesetzt werden. Beides kann zu einer erheblichen Unfallgefahr führen. Kurzschlüsse können beispielsweise Brände auslösen und/oder elektrische Einrichtungen beschädigen. Unter Spannung gesetzte Gegenstände stellen eine erhebliche Gefahr für Personen dar.However, cable stockings have the disadvantage that the friction between the braid and the insulation of the cable and the consequent abrasion of the insulation may result in damage to the cable. In the worst case this can lead to the failure of the insulation. In this case, there is a risk of short circuits and the cable stocking and possibly other objects connected to the cable stocking can be put under tension. Both can lead to a considerable risk of accidents. Short circuits can cause fires and / or damage electrical equipment. Tensioned objects pose a significant hazard to people.
Das Problem der Beschädigung der Isolation tritt insbesondere dann auf, wenn sich die Kabel im Rahmen ihrer bestimmungsgemäßen Verwendung bewegen. Dies ist beispielsweise bei Windkraftanlagen der Fall. Dort wird regelmäßig eine Mehrzahl von Kabeln, die der Übertragung vergleichsweise großer elektrischer Leistungen dienen, auf engstem Raum verlegt und mit Kabelstrümpfen auf verschiedenen Höhen des Turms befestigt. Da bei diesen Windkraftanlagen das Maschinenhaus regelmäßig verschwenkt wird, um den Rotor der Windkraftanlage der Windrichtung entsprechend auszurichten, kommt es ständig zu Bewegungen, die auch auf die Kabel übertragen werden. Ein „Durchscheuern“ der Isolation dieser Kabel kann zu erheblichen Schäden, bis hin zur Zerstörung der gesamten Windkraftanlage durch Brände, führen.The problem of damage to the insulation occurs in particular when the cables move within the scope of their intended use. This is the case, for example, with wind turbines. There is regularly a plurality of cables that serve the transmission of comparatively large electrical services, laid in the narrowest space and attached with cable stockings at different heights of the tower. Since in these wind turbines the machine house is pivoted regularly to align the rotor of the wind turbine according to the wind direction, there are always movements that are transmitted to the cable. A "chafing" of the insulation of these cables can lead to significant damage, including the destruction of the entire wind turbine by fires.
Der Erfindung liegt die Aufgabe zugrunde, einen Kabelstrumpf und eine Windkraftanlage zur Verfügung zu stellen, bei denen eine Beschädigung der Isolation des Kabels durch den Kabelstrumpf vermieden oder zumindest vermindert wird.The invention has for its object to provide a cable stocking and a wind turbine available in which damage to the insulation of the cable is avoided by the cable stocking or at least reduced.
Die Aufgabe wird gelöst durch einen Kabelstrumpf und eine Windkraftanlage mit den Merkmalen der unabhängigen Ansprüche. Die Merkmale der abhängigen Ansprüche betreffen vorteilhafte Ausführungsformen.The object is achieved by a cable sock and a wind turbine with the features of the independent claims. The features of the dependent claims relate to advantageous embodiments.
Erfindungsgemäß weisen die Drähte und/oder Drahtseile des Drahtgeflechts des Kabelstrumpfs eine Kunststoffummantelung auf. Es hat sich gezeigt, dass durch eine derartige Kunststoffummantelung die mechanische Beeinträchtigung der Isolation des Kabels durch den Kabelstrumpf wesentlich reduziert wird. Die Kunststoffummantelung ist nachgiebig und dämpft von dem Geflecht übertragene Kräfte. Die Kunststoffummantelung hat eine reduzierte Härte im Vergleich zu dem Draht oder Drahtseil, so dass ein Abtragen von Kunststoffmaterial der Isolation des Kabels seltener auftritt oder völlig vermieden wird. Gleichwohl überträgt die Kunststoffummantelung Haltekräfte zuverlässig auf die Isolation, weil sie bei Wahl eines geeigneten Kunststoffes einen höheren Reibungskoeffizienten als Stahl aufweist.According to the invention, the wires and / or wire ropes of the wire mesh of the cable stocking on a plastic casing. It has been shown that the mechanical impairment of the insulation of the cable by the cable stocking is substantially reduced by such a plastic sheath. The plastic coating is yielding and dampens transmitted from the network forces. The plastic coating has a reduced hardness compared to the wire or wire rope, so that a removal of plastic material of the insulation of the cable occurs less frequently or is completely avoided. However, the plastic sheath reliably transfers holding forces to the insulation because it has a higher coefficient of friction than steel when a suitable plastic is selected.
Der Kabelstrumpf kann ein Befestigungselement zum Befestigen und/oder Aufhängen des Kabelstrumpfs aufweisen. Bei dem Befestigungselement kann es sich um eine Öse handeln. Das Befestigungselement kann aus einem metallischen Werkstoff, wie beispielsweise einem Stahl, sein. Bei dem Stahl kann es sich um einen rostfreien Stahl handeln. Das Befestigungselement dient dazu, den Kabelstrumpf an einem geeigneten Bauteil, beispielsweise an einem Haken im Turm einer Windkraftanlage, zu befestigen. In der Praxis muss das Befestigungselement nicht zwingend einen Kunststoffüberzug aufweisen, dies ist alternativ jedoch möglich.The cable sock can have a fastening element for fastening and / or hanging the cable sock. The fastener may be an eyelet. The fastener may be made of a metallic material, such as a steel. The steel may be stainless steel. The fastener is used to attach the cable stocking on a suitable component, for example on a hook in the tower of a wind turbine. In practice, the fastener does not necessarily have a plastic coating, but this is alternatively possible.
Der Kabelstrumpf kann ein Fixierelement aufweisen. Das Fixierelement dient zum Fixieren eines Bündels aus Drähten und/oder Drahtseilen des Geflechts. Mit einem derartigen Fixierelement wird ein Bündel aus Drähten und/oder Drahtseilen zusammengefasst, welches den Teil des Kabelstrumpfs, der den Abschnitt des Kabels umgibt, mit der Befestigung des Kabelstrumpfs verbindet. Hierfür kann das Fixierelement in der Praxis im Bereich des Befestigungselements angeordnet sein.The cable sock can have a fixing element. The fixing element serves to fix a bundle of wires and / or wire ropes of the braid. With such a fixing element, a bundle of wires and / or wire ropes is combined, which connects the part of the cable stocking, which surrounds the portion of the cable, with the attachment of the cable stocking. For this purpose, the fixing element can be arranged in practice in the region of the fastening element.
Das Fixierelement kann derart gestaltet sein, dass es das Bündel aus Drähten und/oder Drahtseilen des Kabelstrumpfs zusammenpresst. Hierdurch entsteht ein Kraftschluss zwischen den einzelnen Drähten und/oder Drahtseilen, der zur gleichmäßigen Verteilung der über das Fixierelement oder Befestigungselement eingeleiteten Zugkräfte über alle Drähte und/oder Drahtseile führt. Das Fixierelement kann beispielsweise als Klemmhülse ausgeführt sein.The fixing element may be designed such that it compresses the bundle of wires and / or wire cables of the cable stocking. This creates a frictional connection between the individual wires and / or wire ropes, the uniform distribution over the fixing or Fastening element introduced tensile forces on all wires and / or wire ropes leads. The fixing can be performed for example as a clamping sleeve.
Das Fixierelement kann ebenfalls eine Kunststoffummantelung aufweisen. In der Praxis kann es vorkommen, dass das Fixierelement ebenfalls an der Isolation des Kabels reibt. Durch eine Kunststoffummantelung wird auch im Bereich des Fixierelements die Gefahr einer Beschädigung der Isolation des Kabels beseitigt oder zumindest reduziert.The fixing element can likewise have a plastic casing. In practice, it may happen that the fixing element also rubs against the insulation of the cable. By a plastic coating, the risk of damaging the insulation of the cable is eliminated or at least reduced in the region of the fixing.
Die Kunststoffummantelung der Drähte und/oder der Drahtseile und/oder des Fixierelements kann ein Polyamid als Werkstoff aufweisen. Es hat sich gezeigt, dass Polyamide besonders geeignet sind, um einen wirksamen Schutz der Isolation des Kabels zu gewährleisten. Polyamide zeichnen sich durch gute mechanische Eigenschaften aus, aber auch durch eine reduzierte Brennbarkeit.The plastic coating of the wires and / or the wire cables and / or the fixing element may comprise a polyamide as a material. It has been found that polyamides are particularly suitable to ensure effective protection of the insulation of the cable. Polyamides are characterized by good mechanical properties, but also by a reduced flammability.
In der Praxis kann eine Kunststoffummantelung verwendet werden, die bei einer Vertikalbrennprüfung gemäß der Vorschrift UL94 wenigstens eine Klassifizierung von V-2 erreicht. Die Vorschrift UL 94 „Tests for Flammability of Plastic Materials for Parts in Devices and Appliances“ (Tests zur Brennbarkeit von Kunststoffen für Teile in Geräten und Anwendungen) der Underwriters Laboratories (UL) beschreibt ein Verfahren zur Beurteilung und Klassifizierung der Brennbarkeit von Kunststoffen. Sie findet sich inhaltsgleich in den Normen IEC/DIN EN 60695-11-10 und -20. Eine Klassifizierung nach V-2 bedeutet, dass eine entzündete vertikal eingespannte Probe des Materials innerhalb von 30 Sekunden verlöscht.In practice, a plastic jacket can be used which achieves at least one classification of V-2 in UL94 vertical burn test. UL94 "Tests for Flammability of Plastic Materials for Parts in Devices and Appliances" by Underwriters Laboratories (UL) describes a method for assessing and classifying the flammability of plastics. It can be found in the same standards in the standards IEC / DIN EN 60695-11-10 and -20. Classification according to V-2 means that an inflamed vertically clamped sample of the material will extinguish within 30 seconds.
Die Drähte und/oder Drahtseile des Kabelstrumpfs können aus einem rostfreien Stahl bestehen. In der Praxis kann beispielsweise ein rostfreier Stahl mit der Werkstoffnummer 14401 verwendet werden.The wires and / or wire ropes of the cable stocking can be made of stainless steel. In practice, for example, a stainless steel with the material number 14401 can be used.
Die erfindungsgemäße Windkraftanlage weist ein Kabel auf, das mit einem vorstehend beschriebenen Kabelstrumpf befestigt ist. Durch die erfindungsgemäße Kunststoffummantelung können Beschädigungen der Isolation des Kabels, die aus Bewegungen der Windkraftanlage resultieren, signifikant reduziert werden.The wind turbine according to the invention has a cable which is fastened with a cable stocking described above. Due to the plastic casing according to the invention, damage to the insulation of the cable resulting from movements of the wind turbine can be significantly reduced.
Hierbei handelt es sich in der Regel um Kabel, die durch einen Turm der Windkraftanlage zu dem Maschinenhaus der Windkraftanlage geführt sind. Das Maschinenhaus einer derartigen Windkraftanlage - auch als Gondel bezeichnet - wird in der Praxis abhängig von der wechselnden Windrichtung verschwenkt. Auch treten Schwankungen des Turms aufgrund des Windes auf. Das Verschwenken und die Schwankungen führen zu Bewegungen der Kabel, weshalb die Erfindung in Windkraftanlagen einen besonders hohen Nutzen aufweistThese are usually cables that are routed through a tower of the wind turbine to the nacelle of the wind turbine. The nacelle of such a wind turbine - also referred to as a nacelle - is pivoted in practice depending on the changing wind direction. Also, fluctuations of the tower due to the wind occur. The pivoting and the fluctuations lead to movements of the cables, which is why the invention has a particularly high utility in wind turbines
