Description

Die Erfindung betrifft einen Freileitungsmast aus Schleuderbeton mit wenigstens einer Isoliertraverse.The invention relates to a transmission tower made of spun concrete with at least one insulating truss.

Die Versorgung der Verbraucher mit elektrischer Energie erfolgt über Stromleitungsnetze, wobei die Energie über weite Strecken mit erhöhter Spannung übertragen wird. In den meisten Fällen werden dazu Freileitungen eingesetzt, die an Stahlgittermasten befestigt sind.The supply of electrical energy to the consumer via power lines, the energy is transmitted over long distances with increased voltage. In most cases, overhead lines are used that are attached to steel lattice masts.

In der DE 199 15 499 A1 wird erwähnt, dass Freileitungen für geringe Nennspannungen zwischen 10 kV und 50 kV auch an Schleuderbetonmasten angebracht sein können. Obwohl diese nachteilige Beschränkung auf niedrige Nennspannungen seit längerer Zeit allgemein bekannt ist, sind bisher keine konstruktiven Lösungen vorgeschlagen worden, die es ermöglichen, anstelle von Stahlgittermasten Freileitungsmaste aus Schleuderbeton für hohe Nennspannungen einzusetzen.In the DE 199 15 499 A1 It is mentioned that overhead lines for low rated voltages between 10 kV and 50 kV can also be installed on spun concrete poles. Although this disadvantageous limitation to low nominal voltages has long been common knowledge, so far no constructive solutions have been proposed which make it possible to use, instead of steel lattice towers, transmission towers of spun concrete for high rated voltages.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Freileitungsmast aus Schleuderbeton anzugeben, der für hohe Nennspannungen geeignet ist.The invention is therefore an object of the invention to provide a transmission tower made of spun concrete, which is suitable for high rated voltages.

Zur Lösung dieser Aufgabe ist bei einem Freileitungsmast aus Schleuderbeton der eingangs genannten Art erfindungsgemäß vorgesehen, dass er aus wenigstens zwei Mastsegmenten zusammengesetzt ist.To solve this problem is inventively provided in an overhead tower made of spun concrete of the type mentioned that it is composed of at least two pole segments.

Der Erfindung liegt die Erkenntnis zugrunde, dass Freileitungsmaste aus Schleuderbeton konstruktiv so gestaltet werden können, dass sie in der Lage sind, die beträchtlichen bei hohen Nennspannungen auftretenden Kräfte und Momente aufzunehmen. Mittels der Segmentbauweise können zwei oder mehr Mastsegmente in einem Schleuderbetonwerk vorgefertigt und anschließend an dem gewünschten Aufstellort montiert werden. Besonders vorteilhaft ist dabei die schnelle Montierbarkeit, die Robustheit gegenüber Montage- und Transportlasten sowie die Resistenz gegenüber Umgebungseinflüssen. Ebenso hat es sich herausgestellt, dass erfindungsgemäße Freileitungsmaste gegenüber außerplanmäßigen Lasten besonders widerstandsfähig sind, außerdem sind erfindungsgemäße Freileitungsmaste besonders dauerhaft und wartungsfrei.The invention is based on the finding that transmission towers made of spun concrete can be structurally designed so that they are able to absorb the considerable forces and moments occurring at high nominal voltages. By means of the segmental design two or more mast segments can be prefabricated in a spun concrete plant and then mounted at the desired installation location. Particularly advantageous is the fast mountability, the robustness to assembly and transport loads and the resistance to environmental influences. Likewise, it has been found that transmission lines according to the invention against special loads especially are resistant, also overhead transmission towers according to the invention are particularly durable and maintenance-free.

Vorzugsweise sind die Mastsegmente aus vorgespanntem Beton im sofortigen Verbund hergestellt, wodurch sich eine im Vergleich zu herkömmlichen Konstruktionen besonders schlanke Bauweise ergibt.Preferably, the mast segments are made of prestressed concrete in immediate bond, resulting in a particularly slim compared to conventional designs construction.

Es wird besonders bevorzugt, dass der erfindungsgemäße Freileitungsmast einen konischen Betonsteckstoß zur Verbindung der Mastsegmente aufweist. Die entsprechenden Mastsegmente werden präzise vorgefertigt und am Aufstellort zusammengefügt.It is particularly preferred that the transmission tower according to the invention has a conical concrete plug for connecting the pole segments. The corresponding mast segments are precisely prefabricated and assembled at the installation site.

Alternativ kann es bei dem erfindungsgemäßen Freileitungsmast vorgesehen sein, dass er einen Flanschstoß oder innen oder außen liegende Stahlrohre zur Verbindung der Mastsegmente aufweist. Mit derartigen Flanschstößen kann eine besonders gute Verbindung erzielt werden, die allen auftretenden Lasten standhält.Alternatively, it may be provided in the overhead line mast according to the invention that it has a flange joint or internal or external steel pipes for connecting the mast segments. With such a flange joints, a particularly good connection can be achieved, which withstands all occurring loads.

Da die vorgesehenen Nennspannungen in der Größenordnung von 400 kV zum Teil beträchtliche Masthöhen nach sich ziehen, kann der erfindungsgemäße Freileitungsmast aus Beton bestehen, der wenigstens der Festigkeitsklasse C80/95 entspricht, vorzugsweise kann er aus Beton der Festigkeitsklasse C90/105 bestehen, weiter vorzugsweise aus Beton der Festigkeitsklasse C100/115. In Druckfestigkeiten umgerechnet kann Beton mit einer Mindestdruckfestigkeit von 80 MPa, vorzugsweise 90 MPa, weiter vorzugsweise 100 MPa zur Herstellung des Freileitungsmastes verwendet werden.Since the intended rated voltages of the order of 400 kV sometimes entail considerable mast heights, the pylon according to the invention may consist of concrete which at least corresponds to the strength class C80 / 95, preferably it may consist of concrete of strength class C90 / 105, more preferably Concrete of strength class C100 / 115. In compressive strengths converted concrete with a minimum compressive strength of 80 MPa, preferably 90 MPa, more preferably 100 MPa can be used for the production of the overhead line mast.

Gemäß einer Weiterbildung der Erfindung kann der erfindungsgemäße Freileitungsmast eine Isoliertraverse aufweisen, umfassend einen ersten Traversenabschnitt, der sich näherungsweise waagerecht von dem Freileitungsmast erstreckt, einen zweiten Traversenabschnitt, der mit dem Freileitungsmast einen spitzen Winkel bildet, wobei die beiden Traversenabschnitte in einem Knotenpunkt miteinander verbunden sind, an dem wenigstens eine elektrische Leitung anbringbar ist. Vorzugsweise sind die Isoliertraversen jeweils paarweise angeordnet, die sich symmetrisch an beiden Seiten des Freileitungsmasts erstrecken. Es kann vorgesehen sein, dass an dem Freileitungsmast mehrere Isoliertraversen in unterschiedlichen Höhen angebracht oder anbringbar sind. Mit derart ausgebildeten Isoliertraversen kann eine besonders kompakte Bauweise des Freileitungsmastes erzielt werden, wobei der Einfluss der elektromagnetischen Felder am Boden minimiert wird. Ein weiterer Vorteil ist darin zu sehen, dass der sogenannte Sicherheitsstreifen im Umfeld des Freileitungsmastes reduziert wird, was durch die schlanke Bauweise ermöglicht wird.According to one embodiment of the invention, the overhead line pole according to the invention may have an insulating cross-member comprising a first truss portion extending approximately horizontally from the overhead tower, a second truss portion forming an acute angle with the overhead tower, wherein the two truss sections are interconnected in a node to which at least one electrical line can be attached. Preferably, the Isolierraversen are arranged in pairs, the extending symmetrically on both sides of the overhead line mast. It can be provided that a plurality of insulated crossbeams are mounted or attachable to the overhead line mast at different heights. With such trained Isolierraversen a particularly compact design of the overhead line mast can be achieved, whereby the influence of the electromagnetic fields is minimized at the bottom. Another advantage is the fact that the so-called security strip is reduced in the vicinity of the overhead line mast, which is made possible by the slim design.

Die Gründung des erfindungsgemäßen Freileitungsmastes kann ein Stufenfundament mit Köcher umfassen. Bevorzugt wird jedoch eine alternative Gründung, bei der das Fundament ein in den Boden gerammtes Rohr umfasst und der Freileitungsmast im oberen Teil des Rohrs vergossen ist. Als Rohr wird vorzugsweise ein Stahlrohr verwendet, die Vergusslänge kann in Abhängigkeit der Länge des Freileitungsmastes mehrere Meter betragen.The foundation of the transmission tower according to the invention may comprise a stepped foundation with quiver. However, preference is given to an alternative foundation in which the foundation comprises a tube rammed into the ground and the transmission tower is potted in the upper part of the pipe. As tube preferably a steel tube is used, the Vergusslänge may be several meters depending on the length of the overhead line mast.
