Abstract
Description
[0001] The invention relates to a deflection module for a high-voltage conductor cable and a system for tensioning a conductor cable on high-voltage pylons.
[0002] It is common knowledge that high-voltage lines, for example those for 110 kV or 380 kV, are usually constructed as overhead lines. Conductors are stretched between high-voltage pylons, which - depending on the voltage level - are spaced from 100 m to 400 m apart. The conductors are connected to the crossbeams of the high-voltage pylons by hanging insulators. Power supply systems are generally three-phase, i.e. a conductor system consists of three individual conductors. In order to make the best possible use of the route required for an overhead line, several conductor systems - sometimes even at different voltage levels - are often mounted on a single pylon. In addition, there is an earth wire, which is guided over the tops of the respective high-voltage pylons and serves as lightning protection.
[0003] To reduce the skin effect, an overhead line conductor usually has numerous layers of twisted individual conductors. A steel core is woven into the conductor core to increase tensile strength, and the surrounding conductor layers are made of aluminum. Due to this structure, it is important to ensure that a conductor is not bent too sharply, especially during transport and installation, as this could result in damage. As a rough guideline, the minimum bending radius of the conductor cable should not be less than 30 times its radius.
[0004] To further reduce the skin effect, it is also common to construct a conductor as a multi-wire system, i.e., several conductors arranged in parallel, e.g., in a square with 30cm - 50cm edges and provided with spacers, are electrically connected in parallel. This results in 12 individual conductors in a three-phase conductor system. This makes the construction of such an overhead line particularly difficult because, according to the current state of the art, each conductor is individually strung onto the high-voltage pylon.
[0005] When tensioning conductors, a thin tension cable is used, which has previously been manually positioned between the high-voltage pylons along the desired conductor path. It is connected at its rear end to the conductor to be tensioned, which is usually located on a reel. The tensioning process is initiated by a pulling movement on the tension cable, so that the conductor is pulled along accordingly and thus assumes its desired position on the high-voltage pylons.
[0006] A particular disadvantage is that high-voltage pylons are usually only designed as supporting pylons, which, due to their hanging insulators, are unable to absorb the horizontal forces acting on the conductors. Guyed pylons, which, due to the arrangement of their insulators, can also absorb horizontal forces from the conductors, are usually only provided at a very large distance from each other. In order to prevent these horizontal forces from becoming too great during the tensioning process, it is either necessary to arrange the reel with the overhead line cable to be tensioned at a very large distance from the high-voltage pylon, for example at a distance of more than 120 m. If this space is not available, which is often the case, a makeshift guyed pylon must be erected in the immediate vicinity of the high-voltage pylon in question, which absorbs the horizontal cable forces acting on the high-voltage pylon during the tensioning process. This involves a disproportionately high level of effort.
[0007] In the prior art, a device for installing conductor cables is known from DD 281 061 A1. The device for installing conductor cables on the line support of overhead lines has at least one cable reel and a cable guide. The problem to be solved is to make the cable pulling of overhead lines accident-proof, while simultaneously reducing the assembly effort for inserting the conductor cable into the conductor clamp. For this purpose, a device is created that can be manufactured with little effort, has a universal application area, and is easy to install.
[0008] The device for assembling conductor cables has a triangular roller hanger made up of two legs combined in an articulated node, at the free ends of which rope rollers are arranged, wherein a holder is pivotally articulated between the legs at the node, which holder has a counterpressure roller and wherein the holder is designed to be length-adjustable.
[0009] FR 1 104 834 A describes a device for laying power transmission cables, in particular for attaching conductor cables to the arms of masts.
[0010] This device is constructed to include a plurality of rollers with parallel axes, which have a fixed relative position and are designed to receive the cables to be unwound. All rollers are preferably identical, but it is not excluded to use rollers of different dimensions, for example, larger rollers at the ends of the device.
[0011] DE 199 37 003 B4 discloses a method and a device for dismantling overhead lines that are attached to the support arms of high-voltage transmission towers by means of insulators, such as insulating support chains. The objective is to provide a method that allows for the dismantling of overhead lines to be carried out more easily, reliably, and largely without disruption. Furthermore, a device for carrying out this method is to be presented that has a simple design, is easy to handle, and can be used regardless of the location of the respective transmission tower.
[0012] To solve this problem, a method is specified in which a traction cable is attached to one of the two ends of the overhead line cable to be dismantled and a retaining cable to the other end. A cable guide is also attached to each support arm of the overhead line mast. The overhead line cable to be dismantled is then removed from the insulators and placed on these cable guides. The overhead line cable to be dismantled is then pulled over the cable guides using the attached traction cable. The retaining cable tautly tensions the overhead line cable so that it does not accidentally slip out of one of the cable guides.
[0013] DE 198 57 131 A1 discloses a method for installing a cable on a high-voltage overhead line. There is a need to retrofit cables to high-voltage overhead line cables in order to utilize existing cable routes and enable cost-effective cable installation. Retrofitting is particularly common for fiber optic cables used in telecommunications networks.
[0014] This task is solved by hooking roller slings into the rope to guide the cable, pulling a winch rope parallel to the cable, guiding the winch rope from the roller slings and then pulling it back again from a winch on the ground.
[0015] Based on this state of the art, the object of the invention is to simplify the tensioning of conductor cables for high-voltage lines.
[0016] This object is achieved by a deflection module according to the invention for a high-voltage conductor cable, comprising an arcuate deflection channel which is designed such that a conductor cable can be movably guided therein along its extent, a module holder with a connecting device which is intended to be detachably connected to a high-voltage pylon and a spacer element by means of which a mechanically rigid connection is formed between the deflection channel and the module holder.
[0017] The inventive idea here is to upgrade the high-voltage pylon, over which the conductor cable is to be stretched, into a guyed pylon by temporarily installing deflection modules, thus eliminating the need for separate construction. The high-voltage pylon, designed as a supporting pylon, is certainly capable of absorbing horizontal forces; it is only the hanging insulator, which, due to its hanging attachment to a single point on the pylon's crossbeam, is unable to absorb horizontal forces acting on the conductor cable it supports. This is achieved, according to the invention, by the deflection modules to be mounted on the high-voltage pylon. Once the desired conductor cables have been tensioned, the deflection modules must then be removed from the high-voltage pylon.
[0018] A deflection module first has a deflection channel for the conductor cable to be tensioned. This is necessary to guide the conductor cable from the base of the high-voltage pylon to the desired position in the upper area. The deflection channel must be designed in such a way that the conductor cable can be moved along the deflection channel relative to the high-voltage pylon. This enables the cable to be pulled through the deflection channel. The deflection channel must also be designed with a curved radius, which prevents excessive bending of the conductor cable. A bend of approximately 90° in a deflection channel is considered a typical size, allowing for particularly flexible cable guidance along the high-voltage pylon.
[0019] The module holder with connecting device serves to establish a temporary and force-locking connection to the high-voltage pylon. This can be, for example, a screw, clamp, and / or plug connection, which are particularly easy to remove. It is advantageous that high-voltage pylons are usually designed as lattice structures with numerous struts. A strut can be particularly easily enclosed by a connecting element across its diameter, thus creating a simple and secure connection. Of course, multiple connection points between a module holder and the high-voltage pylon are also possible, thus creating a particularly stable connection.
[0020] The spacer element serves to ensure a distance between the high-voltage pylon and the deflection channel and thus to prevent possible contact of the conductor cable to be tensioned with the high-voltage pylon.
[0021] In a particularly preferred embodiment of the deflection module according to the invention, the deflection channel is formed at least in sections by a respective segment section of a freely rotatable roller with a groove-shaped recess for guiding the conductor cable along its circumference.
[0022] The movement of a conductor through the deflection channel formed, at least in part, by the groove-shaped recess can be achieved particularly easily and with low friction by a rotating movement of the roller. Even if a rotating movement of the roller does not result in any relative movement to a conductor guided over the roller, this is considered a movement of the conductor through a deflection channel.
[0023] In a further embodiment of the deflection module according to the invention, a plurality of freely rotatable rollers arranged parallel in a common plane and along an arc are provided, so that a polygon-like deflection channel for a conductor cable is formed along the arc.
[0024] By using a large number of small rollers arranged in an arc-like pattern, a significant weight saving is achieved compared to a single large roller, which must have a minimum diameter of at least 30 times the conductor diameter to avoid damage to the conductor during tensioning. This significantly simplifies the inevitably manual installation of the deflection modules on the high-voltage pylon. Approximating the minimum radius of the deflection channel with a roller polygon prevents damage to the conductor during installation in a similar way to a deflection channel with the same radius that runs exactly in the shape of a circular segment. The number of rollers is, for example, 3 to 12, depending on the arc radius to be approximated and the roller diameter, whereby a smaller roller diameter requires a larger number of rollers.
[0025] According to a further variant of the deflection module according to the invention, several parallel deflection channels are provided. This enables, in particular, the synchronous pulling of several conductor cables through one of the deflection channels. The parallel arrangement of the deflection channels is particularly useful for the parallel guidance of several conductor cables from the conductor cable rollers provided at the base of the mast into the upper area of the mast, where the cables are then inserted into the desired tensioning positions.
[0026] In a particular embodiment of the deflection module according to the invention, freely rotatable rollers of adjacent deflection channels arranged along the same axis of rotation are replaced by a common freely rotatable roller with a corresponding number of parallel groove-shaped depressions.
[0027] This results in further weight savings and a reduction in the number of components that need to be temporarily installed. Furthermore, the distance between adjacent deflection channels can be further reduced, resulting in simplified conductor routing from the base of the high-voltage pylon to the upper area. When several conductors are to be routed synchronously, for example, a rotation of the plane of the parallel conductors, for example by 90°, is particularly easy to achieve if the conductors are arranged as close together as possible. Synchronous pulling of the individual conductors eliminates the need for each individual roller to rotate freely, so combining individual rollers does not limit functionality.
[0028] According to a particularly preferred deflection module variant, the spacer element is adjustable so that a selectable distance and / or a selectable orientation of the deflection channel to the module holder can be realized.
[0029] This allows for particularly simple installation of the deflection modules on the mast. The desired conductor routing from the base of the high-voltage mast to its upper section requires the arrangement of the deflection modules' deflection channels at very specific positions relative to the mast. On the other hand, the module holders of the deflection modules can only be mounted on the high-voltage mast, and specifically on its lattice struts. In some cases, only a specific position or orientation is possible, which is not ideal for the conductor routing.
[0030] A lockable, telescopic extension of a spacer element or a lockable swivel joint are devices that allow for a correspondingly high degree of flexibility when installing the deflection modules or the conductor cable guide. However, the permanent installation of additional intermediate, extension, or bend pieces into the spacer element also achieves the same purpose.
[0031] The object is also achieved by a system for tensioning a conductor cable on high-voltage pylons, comprising a high-voltage pylon and at least one first deflection module connected thereto according to one of claims 1 to 6. The corresponding advantages of such a system have already been explained at the outset.
[0032] In a further embodiment of the system according to the invention, the first deflection module is arranged on the high-voltage pylon in such a way that the first end of the deflection channel of the first deflection module is aligned in the imaginary extension of the conductor cable to be tensioned in its desired position on the high-voltage pylon and the second end of the deflection channel is preferably aligned vertically.
[0033] The conductor to be tensioned is first introduced vertically from the conductor pulley into the second end of the deflection channel, where it is deflected approximately 90°. It is then guided approximately horizontally out of the first end of the deflection channel, slightly in front of the insulator that will support the conductor on the pylon. During the subsequent tensioning process, the conductor is then pulled with the desired sag to a comparable position on the adjacent high-voltage pylon. This arrangement allows the first deflection module to absorb almost all of the horizontal tensile force from the insulator, allowing for trouble-free tensioning of the conductor.
[0034] According to a further embodiment of the system according to the invention, further deflection modules are arranged on the high-voltage pylon in such a way that a conductor cable subjected to a tensile force can be movably guided from the base of the high-voltage pylon near the pylon to a crossbeam located in the upper region and from there along the crossbeam to the second end of the deflection channel of the first deflection module.
[0035] The arrangement of the additional deflection modules ensures that the cable is guided from the base of the high-voltage pylon to the first deflection module. This depends heavily on the shape of the pylon. In many cases, a deflection module at the base of the high-voltage pylon would be advisable to deflect the conductor, which is unwound horizontally from the conductor pulley, into a vertical position close to the pylon. At the level of the crossbeam onto which the conductor is to be inserted, a further deflection module must be provided, which guides the conductor to the outer area of the crossbeam. There, in turn, a deflection module must be provided, which feeds the conductor from a vertical direction, i.e., from above or below, to the first deflection module.
[0036] However, this is only one example of a multitude of possible arrangements for the other deflection modules. An arrangement is also envisaged in which the deflection channels of all deflection modules for a respective conductor cable are arranged in the same plane. In this case, the respective conductor cables also run in parallel planes. This makes it particularly easy to tension the conductor cables with a traction cable into the upper area of the high-voltage pylon.
[0037] In a particularly preferred embodiment of the system according to the invention, deflection modules are provided with a plurality of parallel deflection channels, so that a plurality of conductor cables connected to one another at their respective one end can be pulled together over the deflection modules.
[0038] Especially the synchronous pulling of several conductor cables, which, as mentioned at the beginning, are arranged in their final arrangement, for example in a square or triangle, at a distance of 30 cm - 50 cm to reduce the skin effect, leads to a considerable reduction in the effort required for tensioning the conductor cables.
[0039] Preferably, the conductor cables, which are to be pulled synchronously, are connected at one end to a common connecting bar. The conductor cables are attached to one side of the connecting bar, preferably at an equidistant distance, which is adapted to the distances between the parallel deflection channels. A traction cable is connected centrally to the opposite side of the connecting bar, with which the bar and the conductor cables can be pulled over the deflection modules.
[0040] Further advantageous design options can be found in the other dependent claims.
[0041] The invention, further embodiments and further advantages will be described in more detail with reference to the exemplary embodiments shown in the drawings.
[0042] It shows Fig. 1 exemplary system for tensioning a conductor cable, Fig. 2 an exemplary first deflection module, Fig. 3 a roll with a large roll diameter Fig. 4 different roller variants with small roller diameter and Fig. 5 a connecting sword with four conductor ropes and a pull rope
[0043] Fig. 1 shows an exemplary system 10 for tensioning a conductor cable. In the illustrated variant, it is used for synchronously tensioning four conductor cables 28 on a mast 20, which, for example, has a height of 30 m - 70 m. The mast has two crossbeams 22, 24, whereby the four conductor cables 28 to be tensioned are intended to form a connected phase conductor of a 3-phase system and are to be held at the outer end of the crossbeam 24 by an insulator (not shown). At the base of the mast 20, the four conductor cables are unwound from a respective conductor cable reel and provided, as indicated by the arrow with the reference number 26. Via a fourth deflection module 18, which has a total of four parallel deflection channels, the four conductor cables 28 are deflected close to the mast in an approximately vertical direction and guided into the upper mast area up to the third deflection module 16 mounted there, which in turn also has four parallel deflection channels.On the way up, the plane of the four parallel conductor cables undergoes a torsion of approximately 90°, as indicated in the drawing.
[0044] Via the third deflection module 16, the conductor cables are now deflected in an approximately horizontal direction and guided to the left outer edge of the crossbeam 24, where they are deflected vertically by a second deflection module 14 and fed to the first deflection module 12. The respective deflection modules are each connected to the mast 20 or its crossbeams 22, 24 using module holders and spacer elements (not shown). After tensioning the respective conductor cables, the deflection modules must be removed again.
[0045] All deflection modules 12, 14, 16, and 18 are each provided with four deflection channels, each of which is assigned to a conductor cable. In this case, the deflection channels are indicated as a respective rotating roller with a groove-like depression, although, of course, polygonal deflection channels formed from several smaller rollers arranged on a circular path can also be used. In the second deflection module 14, a slight offset of the parallel deflection channels is indicated in order to feed the conductor cables exactly perpendicularly to the corresponding deflection channel of the first deflection module 12. However, this is not absolutely necessary. It is also conceivable that—as with the deflection modules 12, 16, and 18—all parallel deflection channels are arranged around the same imaginary axis of rotation.
[0046] Fig. Figure 2 shows a first exemplary deflection module 40. This comprises an arcuate deflection channel, both ends of which are indicated by reference numerals 57 and 58. The arcuate deflection channel is approximated in a polygonal manner by several freely rotatable rollers 42 with groove-like recesses, so that the minimum bending radius of the conductor cable 56 guided through the deflection channel 57-58 is not exceeded. The use of the rollers 42 enables a particularly simple and low-friction movement of the conductor cable through the deflection channel.
[0047] The six rotatable rollers 42, arranged in a common plane in this example, are connected to a spacer element 44 via a common holder. This spacer element 44 has a length-adjustable cylinder 46 for geometric adjustment, which can be locked in the desired length position, for example, by a screw connection. The length-adjustable cylinder 46, in turn, is connected at its opposite end to a device for adjusting the orientation, for example, a ball joint with a locking device. The latter two devices are optional components of the spacer element 44, which allow increased flexibility in the arrangement of the deflection module 40 on the high-voltage pylon—in this case, on the struts 54 of a crossbeam.
[0048] The orientation adjustment device 48 is connected to a module holder 50, which is frictionally connected to a high-voltage pylon or the associated struts 54. In this case, a U-shaped clamp is provided, which encloses a strut in its cross-section and is detachably connected to a strut 54 via a locking device. This makes the deflection module 40 particularly easy to mount on a pylon—also due to its reduced weight through the use of several smaller rollers—and to disassemble again.
[0049] Fig. In comparison, Figure 3 shows a pulley with a large diameter 60, which is at least large enough to ensure that the minimum bending radius—for example, 0.8 m—of the conductor cable 68 guided over the pulley 62 is not exceeded. The pulley 62 is rotatable about the rotation axis 66 and has a groove-like recess 64, which in this case serves as a deflection channel in sections.
[0050] Fig. Figure 4 shows various roller variants with a small diameter, which can be used to approximate the curved shape of several parallel deflection channels in a polygonal manner. Reference number 70a shows four identical individual rollers 72 arranged around the same rotation axis 82, each of which guides a conductor cable 80 in a respective groove-like recess 78.
[0051] Reference number 70b shows two double or tandem pulleys 74, each guiding two conductor cables 80 in corresponding groove-like recesses. Finally, reference number 70c depicts a single quadruple pulley 76, which has four groove-like recesses 78, each of which guides a conductor cable 78. This illustration illustrates that the assembly effort is advantageously reduced with such multiple pulleys. Of course, in addition to the 4-fold variant shown, 2-, 3-, or 5-fold variants are also conceivable.
[0052] Fig. Finally, Figure 5 shows, with reference number 90, a connecting bar 92 with four conductor cables 100 and a pulley cable 94. The four conductor cables 100 are also guided over a quadruple pulley 96, which is rotatable about a pivot axis 98. When using such a connecting bar 92, it is particularly advantageous if the conductor cables 100 are guided in mutually parallel planes from the base of the high-voltage pylon to the insertion point in the upper region of the pylon, i.e., in the direction of pull, just before the insulator intended to support the conductor. Then, the connecting bar 92 with the pulley cable 94 can be easily pulled from the lower region of the high-voltage pylon over all deflection modules to the upper region of the high-voltage pylon and from there to all other high-voltage pylons, pulling the four conductor cables (in this case) through all deflection channels.
[0053] Of course, other conductor cable guide variants are also available, such as in Fig. 1, can be realized with such a connecting sword 92, but it could possibly mean a certain amount of additional effort in guiding the connecting sword into the upper mast area.
