Definitions
- the invention relates to an overhead line for power transmission lines which is designed as a hollow rope with a predetermined rope diameter and a cable sheath of one or more Leithnrahtfagen, wherein in the hollow rope, a tubular cable sheath support is arranged.
- corona discharges do not only lead to considerable losses of electrical energy, the so-called corona losses, on high-voltage overhead lines, but in addition, a considerably disturbing corona noise arises at the same time.
- These corona discharges are favored by low air pressure and high humidity.
- Such corona discharges are generally difficult to prevent in so-called standard cables having as bundle conductors a steel core of a plurality of steel wires and a multi-layered cable jacket of conductive wires which are either aluminum wires or aluminum alloy wires.
- an overhead cable designed as a hollow cable in which pipe sections form a cable jacket support. These pipe sections are coupled via specially designed pipe connectors (see US 2 225 333 A).

- the invention is initially based on the recognition that a standard rope or any overhead line can be replaced by a hollow rope with a significantly larger rope diameter to avoid corona discharges at the same or even increased transmission power, or at least significantly reduce. Because due to the considerably larger rope diameter as an electrode is realized with less fringe field strength, so that corona discharges and resulting power losses and noise nuisance are reduced at least to a considerable extent.
- the hollow rope can be interpreted and optimized so that the mast load is equal to or even lower than standard cables, also the modulus of elasticity and the coefficient of thermal expansion are almost equal. In order to achieve such an optimization, the parameters outer cable diameter, number of wires and their wire diameter of the individual wire layers and the materials used are varied and matched accordingly.

- the cable sheath support is designed as a support element with a hollow cross-section and forms completely or at least at predetermined intervals a support for the cable sheath. Furthermore, the cable sheath support is designed as a flexible elastic tube with a closed or perforated pipe jacket. Preferably, a corrugated pipe with a closed or perforated pipe jacket is used as a cable jacket support whose outer diameter corresponds to the inner diameter of the hollow cable. In this way, a hollow rope can be realized, which is characterized not only by high stability and load capacity, but also by such a flexibility that the overhead line rope can be easily wound up for transport on drums and can be mounted on towers during assembly on rollers on masts, without the risk of kinking.
- a relining is achieved by a full rope in the region of the hollow cable ends or the clamping areas.
- the transition from the tubular cable sheath support or the corrugated tube to the solid rope takes place in that the remote full rope is inserted into the cable sheath support until the layers of full solid rope touch the sheathing support and thus a diameter constancy of the support structure is ensured.
- the insertion length depends on the diameter ratio of the Cable sheath support inside to the remote full outside as well as weight and damping requirements.
- the Voflseilabitese are expediently stepped down in their negative and / or positive sense at their protruding into the cable sheath support ends.
- the wire ends of the step-down full-pitched layers are not tied, therefore, jump on and touch with ever decreasing force, the inner surface of the tubular cable sheath support.
- an optimized vibration damping is achieved for the hollow cable.
- the relining of the hollow rope according to the invention with a trained as a full-rope standard rope takes place at the ends of the hollow rope and those places where according to line planning, taking into account the rope sagging and the requirements of rope regulation and retightening a clamp must be set.
- relining arise no or at most low development costs in the field of fittings, because the terminals standard constructions can be used, which only have to correspond to the larger outer diameter of the overhead line according to the invention.

Description
Die Erfindung betrifft ein Freileitungsseil für Hochspannungsfreileitungen welches als ein Hohlseil mit einem vorgegebenen Seildurchmesser und einem Seilmantel aus einer oder mehreren Leitungsdrahtfagen ausgebildet ist, wobei in dem Hohlseil eine rohrartige Seilmantelstütze angeordnet ist.The invention relates to an overhead line for power transmission lines which is designed as a hollow rope with a predetermined rope diameter and a cable sheath of one or more Leithnrahtfagen, wherein in the hollow rope, a tubular cable sheath support is arranged.
Bekanntlich führen an Hochspannungsfreileitungen Koronaentladungen nicht nur zu erheblichen Verlusten an elektrischer Energie, den so genannten Koronaverlusten, sondern darüber hinaus entsteht zugleich ein erheblich störender Koronalärm. Diese Koronaentladungen werden durch geringen Luftdruck und hohe Luftfeuchtigkeit begünstigt. Solche Koronaentladungen lassen sich im Allgemeinen bei so genannten Standardseilen kaum verhindern, welche als Bündelleiter einen Stahlkern aus einer Mehrzahl von Stahldrähten und einen mehrlagigen Seilmantel aus Leitungsdrähten aufweisen, bei denen es sich entweder um Aluminiumdrähte oder Drähte aus Aluminiumlegierungen handelt.As is known, corona discharges do not only lead to considerable losses of electrical energy, the so-called corona losses, on high-voltage overhead lines, but in addition, a considerably disturbing corona noise arises at the same time. These corona discharges are favored by low air pressure and high humidity. Such corona discharges are generally difficult to prevent in so-called standard cables having as bundle conductors a steel core of a plurality of steel wires and a multi-layered cable jacket of conductive wires which are either aluminum wires or aluminum alloy wires.
Zur Vermeidung der vorbehandelten Probleme ist ein als Hohlseil ausgebildetes Freileitungsseil bekannt, bei dem Rohrabschnitte eine Seilmantelstütze bilden. Diese Rohrabschnitte sind über speziell ausgebildete Rohrverbinder gekuppelt (vgl. US 2 225 333 A). Ferner kennt man ein Hohlseil mit einem Seilmantel aus mehreren Leitungsdrahtlagen, wobei in dem Hohlseil eine rohrartige Seilmantelstütze angeordnet ist, die von in vorgegebenen Abständen angeordneten Auflagern gebildet wird. Diese Auflager sind über Längsstäbe miteinander verbunden (vgl. US 1 928 188 A).In order to avoid the pretreated problems, an overhead cable designed as a hollow cable is known, in which pipe sections form a cable jacket support. These pipe sections are coupled via specially designed pipe connectors (see US 2 225 333 A). Furthermore, a hollow rope having a cable sheath of a plurality of conductor wire layers is known, wherein in the hollow rope a tubular cable sheath support is arranged, which is formed by arranged at predetermined intervals Auflagern. These supports are interconnected by longitudinal bars (see US 1 928 188 A).
Der Erfindung liegt das technische Problem zugrunde, ein Freileitungsseil für Hochspannungsleitungen der eingangs beschriebenen Ausführungsform zu schaffen, bei welchem nicht nur Koronaentladungen weitgehend vermieden werden, sondern welches darüber hinaus in verlegetechnischer und festigkeitsmäßiger Hinsicht einem Standardseil oder den Projektanforderungen mit gleicher oder verbesserter Übertragungsleistung entspricht.The invention is based on the technical problem of providing an overhead line for high-voltage lines of the embodiment described above, in which not only corona discharges largely avoided but which also corresponds, in terms of installation and strength, to a standard cable or the project requirements with the same or improved transmission performance.
Dieses Problem löst die Erfindung bei einem Freileitungsseil gemäß Anspruch 1.This problem is solved by the invention in an overhead line according to
Die Erfindung geht zunächst einmal von der Erkenntnis aus, dass sich ein Standardseil oder ein beliebiges Freileitungsseil durch ein Hohlseil mit deutlich größerem Seildurchmesser ersetzen lässt, um bei gleicher oder sogar erhöhter Übertragungsleistung Koronaentladungen zu vermeiden oder zumindest deutlich zu vermindern. Denn aufgrund des erheblich größeren Seildurchmessers wird gleichsam eine Elektrode mit geringerer Randfeldstärke verwirklicht, so dass Koronaentladungen sowie daraus resultierende Leistungsverluste und Geräuschbelästigungen zumindest in erheblichem Maße reduziert werden. Dabei lässt sich das Hohlseil derart auslegen und optimieren, dass die Mastbelastung gleich oder sogar geringer als bei Standardseilen ist, ferner der E-Modul und der Temperaturausdehnungskoeffizient nahezu gleich sind. Um eine solche Optimierung zu erreichen, werden die Parameter Seilaußendurchmesser, Anzahl der Leitungsdrähte und deren Drahtdurchmesser der einzelnen Leitungsdrahtlagen sowie die eingesetzten Materialien entsprechend variiert und aufeinander abgestimmt. Die den Seilmantel bildenden Leitungsdrähte bestehen aus Aluminium und/oder einer Aluminiumlegierung wie beispielsweise AlMgSi und/oder sind als Stalumdrähte und/oder geeigneter Stahldraht ausgebildet. Unter Stalum ist ein hochfester Stahldraht mit einer beispielsweise im Extrusionsverfahren aufgebrachten Aluminiumbeschichtung zu verstehen.The invention is initially based on the recognition that a standard rope or any overhead line can be replaced by a hollow rope with a significantly larger rope diameter to avoid corona discharges at the same or even increased transmission power, or at least significantly reduce. Because due to the considerably larger rope diameter as an electrode is realized with less fringe field strength, so that corona discharges and resulting power losses and noise nuisance are reduced at least to a considerable extent. In this case, the hollow rope can be interpreted and optimized so that the mast load is equal to or even lower than standard cables, also the modulus of elasticity and the coefficient of thermal expansion are almost equal. In order to achieve such an optimization, the parameters outer cable diameter, number of wires and their wire diameter of the individual wire layers and the materials used are varied and matched accordingly. The cable wires forming the cable sheath are made of aluminum and / or an aluminum alloy such as AlMgSi and / or are formed as stalum wires and / or suitable steel wire. Under Stalum is a high-strength steel wire with an example applied by extrusion aluminum coating to understand.
Jedenfalls sind keine oder nur geringe Verstärkungen der vorhandenen Masten beim Seilaustausch erforderlich, während durch die in dem Hohlseil angeordnete Seilmantelstütze eine hohe Belastbarkeit des Freileitungsseiles selbst unter Berücksichtigung jener Querkräfte erreicht wird, wie sie beispielsweise an Klemmen von Abstandhaltern und/oder im Bereich von Tragklemmen auftreten.In any case, no or only small reinforcements of the existing masts are required for Seilaaustausch, while a high load capacity of the overhead line itself is achieved by taking into account those transverse forces, as they occur for example on terminals of spacers and / or in the range of support clamps by arranged in the hollow rope sheath ,
Die Seilmantelstütze ist als ein Stützelement mit hohlem Querschnitt ausgebildet und bildet vollständig oder zumindest in vorgegebenen Abständen ein Auflager für den Seilmantel. Ferner ist die Seilmantelstütze als biegeelastisches Rohr mit geschlossenem oder perforiertem Rohrmantel ausgebildet. Bevorzugt findet ein Wellrohr mit geschlossenem oder perforiertem Rohrmantel als Seilmantelstütze Verwendung, dessen Außendurchmesser dem Innendurchmesser des Hohlseiles entspricht. Auf diese Weise lässt sich ein Hohlseil verwirklichen, welches sich nicht nur durch hohe Stabilität und Beanspruchungsfähigkeit auszeichnet, sondern auch durch eine solche Biegsamkeit, dass sich das Freileitungsseil unschwer für Transportzwecke auf Trommeln aufwickeln lässt und im Zuge der Montage über Rollen auf Masten aufziehen lässt, ohne dass Knickgefahr besteht. Tatsächlich lassen sich dem Seildurchmesser entsprechende Biegeradien trotz des verhältnismäßig großen Außendurchmessers des Hohlseiles verwirklichen. Das gilt insbesondere unter Berücksichtigung der wellenförmigen Oberfläche der Seilmantelstütze, wenn diese eben als Wellrohr ausgebildet ist. Die Seilmantelstütze kann selbst auch aus Aluminium oder einer Aluminiumlegierung bestehen.The cable sheath support is designed as a support element with a hollow cross-section and forms completely or at least at predetermined intervals a support for the cable sheath. Furthermore, the cable sheath support is designed as a flexible elastic tube with a closed or perforated pipe jacket. Preferably, a corrugated pipe with a closed or perforated pipe jacket is used as a cable jacket support whose outer diameter corresponds to the inner diameter of the hollow cable. In this way, a hollow rope can be realized, which is characterized not only by high stability and load capacity, but also by such a flexibility that the overhead line rope can be easily wound up for transport on drums and can be mounted on towers during assembly on rollers on masts, without the risk of kinking. In fact, corresponding to the rope diameter corresponding bending radii despite the relatively large outer diameter of the hollow rope can be realized. This applies in particular taking into account the undulating surface of the cable jacket support, if this is just designed as a corrugated pipe. The cable jacket support itself can also consist of aluminum or an aluminum alloy.
Nach Lehre der Erfindung wird im Bereich der Hohlseilenden bzw. der Klemmbereiche eine Unterfütterung durch ein Vollseil erreicht. Der Übergang von der rohrartigen Seilmantelstütze bzw. dem Wellrohr zum Vollseil erfolgt dadurch, dass das abgesetzte Vollseil in die Seilmantelstütze eingeschoben wird bis die Lagen des vollständigen Vollseiles die Seilmantelstütze berühren und damit eine Durchmesserkonstanz der Stützkonstruktion sichergestellt ist. Die Einschublänge hängt von dem Durchmesserverhältnis von der Seilmantelstütze innen zu dem abgesetzten Vollteil außen sowie von Gewichts- und Dämpfungserfordernissen ab. Um einen möglichst fließenden Übergang von der rohrförmigen Seilmantelstütze zum vollen Vollseil zu erreichen, sind zweckmäßigerweise die Voflseilabschnitte an ihren in die Seilmantelstütze vorkragenden Enden in negativem und/oder positivem Sinn stufenförmig abgesetzt. Die Drahtenden der stufenförmig abgesetzten Vollseillagen werden nicht abgebunden, springen daher auf und berühren mit immer geringer werdender Kraft die Innenfläche der rohrförmigen Seilmantelstütze. Dadurch wird eine optimierte Schwingungsdämpfung für das Hohlseil erreicht. Die Unterfütterung des erfindungsgemäßen Hohlseiles mit einem als Vollseil ausgebildeten Standardseil erfolgt an den Enden des Hohlseiles und an jenen Stellen, wo gemäß Trassenplanung unter Berücksichtigung der Seildurchhänge und den Erfordernissen von Seilregulierung und Nachspannen eine Klemme gesetzt werden muss. Durch die Unterfütterung entstehen keine oder allenfalls geringe Entwicklungskosten im Bereich der Armaturen, denn bei den Klemmen können Standardkonstruktionen eingesetzt werden, die lediglich dem größeren Außendurchmesser des erfindungsgemäßen Freileitungsseiles entsprechen müssen. Dies gilt für Abspannarmaturen im Bereich von Abspannmasten ebenso wie für Tragarmaturen im Bereich von Tragmasten und Verbindungsarmaturen zur Verbindung erfindungsgemäßer Freileitungsseile zu einer Hochspannungsfreileitung. Durch die Unterfütterung wird ferner ein kritisches Schwingungsverhalten im Bereich der Trag- und Abspannklemmen zumindest gedämpft. Ferner hat die Unterfütterung keinen negativen Einfluss auf die Reduktion der Koronaentladungen.According to the teaching of the invention, a relining is achieved by a full rope in the region of the hollow cable ends or the clamping areas. The transition from the tubular cable sheath support or the corrugated tube to the solid rope takes place in that the remote full rope is inserted into the cable sheath support until the layers of full solid rope touch the sheathing support and thus a diameter constancy of the support structure is ensured. The insertion length depends on the diameter ratio of the Cable sheath support inside to the remote full outside as well as weight and damping requirements. In order to achieve the most fluent transition possible from the tubular cable sheath support to the full solid rope, the Voflseilabschnitte are expediently stepped down in their negative and / or positive sense at their protruding into the cable sheath support ends. The wire ends of the step-down full-pitched layers are not tied, therefore, jump on and touch with ever decreasing force, the inner surface of the tubular cable sheath support. As a result, an optimized vibration damping is achieved for the hollow cable. The relining of the hollow rope according to the invention with a trained as a full-rope standard rope takes place at the ends of the hollow rope and those places where according to line planning, taking into account the rope sagging and the requirements of rope regulation and retightening a clamp must be set. By relining arise no or at most low development costs in the field of fittings, because the terminals standard constructions can be used, which only have to correspond to the larger outer diameter of the overhead line according to the invention. This applies to guy fixtures in the range of guy towers as well as for support fittings in the field of pylons and connection fittings for connecting overhead cables according to the invention to a power transmission line. By relining a critical vibration behavior in the area of the support and Abspannklemmen is also at least damped. Furthermore, the relining has no negative impact on the reduction of corona discharges.
