Definitions
- the invention relates to a method having the features according to the preamble of claim 1.
- the invention has for its object to provide a method for installing an optical waveguide, which is safer than previously known method during ongoing operation of the energy transmission system - ie during a current flow in electrical phase conductors that run between the two transmission towers.
- the invention provides that a support cable and a traction cable for the optical waveguide with the roller device between a located below the Erdseilanitatisstelle mast point of an overhead line mast are transported to a located below the Erdseilanitatisstelle mast point of the other overhead line mast and the installation of the optical waveguide is taking advantage of the supporting cable, wherein the hauling rope and the supporting rope hang on the earth rope via the roller device during the transport to the other overhead mast.
- An essential advantage of the method according to the invention is that, in contrast to the previously described prior art method described above, the earth wire is not replaced in this case; it can thus maintain its electrical function during the entire installation process. At no time is the electrical function of a ground wire missing between the transmission towers.
- a second significant advantage of the inventive method is the fact that with this any number of additional optical waveguides can be installed at mast points other than the Erdseilanitatisstelle.
- a third significant advantage of the method according to the invention is the great safety; because for the installation of the optical fiber, the additionally mounted carrying rope can be used as a supporting rope. This makes it possible to use the Erdseil as an additional safety rope and not as a "supporting" rope.
- the carrying cable is stretched between the two mast points and the pulling cable is passed through the optical waveguide. is set by one end of the traction cable connected to the optical waveguide and this is held by the support cable via the roller device in the direction of the other Freit line mast pulled along the support cable along.
- Optical waveguide so on the tensioned suspension cable; for additional security or risk reduction may optionally be used for additional securing the ground wire, for example by the Erdseil remains coupled to the support cable.
- upper roller elements and lower double roller elements are each connected to each other by means of a dielectric tether and the resulting Rollentragerprese be connected to each other by means of at least one spacer rope to form the roller device, the upper roller of the upper roller elements respectively is attached to the earth rope, with the hanging on the earth rope roller carrier pairs the support cable and the traction cable are pulled from the master station of one overhead line to the mast point of the other overhead line and thereby held by the Erd ⁇ rope (or "worn”), the suspension cable is stretched between the two mast points and subsequently the optical waveguide is separated from the one free cable by means of the pull cable.
- the support cable holds the pull rope and the optical waveguide (or carries) and wherein the Erdseil secures the support rope in the event that the support rope breaks against falling down.
- the Erdseil serves in a first installation phase as a "supporting" or holding rope to attach the support cable and the traction cable between the two transmission towers.
- the carrying cable serves as a "carrying" or holding cable for the pull rope and the optical waveguide in order to install the optical waveguide;
- the earth rope no longer has a "supporting” or holding function, but serves only to secure the carrying cable and thus the pull rope and the optical waveguide, should the carrying rope break.
- adjacent Rollentragercrue be - m ⁇ longitudinal direction of the Erdseiles, the lifting rope and the traction cable seen - by means of the lower double roller elements connecting lower spacer and the cable by means of the upper roller members connecting upper spacer rope connected together.
- two parallel - at least substantially parallel - distance ropes is achieved that the distance between the Rollentragercruen both the Anitatis- or interface to the earth wire and on the Anbmdungs- or interface to the support cable is equal to, at least in Wesent ⁇ union is equal,
- the adjacent pairs of roller carriers are connected to one another such that their distance amounts to a maximum of 50 m.
- an upper double roller element can be used, preferably one which is identical to the lower double roller element.
- the invention also relates to an arrangement for installing an optical waveguide between two transmission towers of an energy transmission system with a Erdseilanitatis slaughter the two overhead towers connecting ground wire and an attached roller device.
- a carrying cable is clamped between a mast point of one free-line mast located below the earth cable connection point and a mast point of the other overhead line mast located below the earth cable connection point, a pull cable for the optical waveguide via the roller device of FIG tensioned supporting cable is held and the traction cable and the supporting cable are secured over the roller device against falling from the ground wire, if the supporting rope breaks.
- upper roller elements and lower double roller elements are each connected to one another by means of a dielectric tether, and the resulting roller carrier pairs are coupled to one another, for example, by means of at least one spacer cable.
- Neighboring Rollentragercrue are preferred - seen in the longitudinal direction of the earth cable, the support cable and the traction cable - connected by means of a lower double roller elements connecting lower spacer and by means of an upper roller elements connecting upper spacer rope.
- Adjacent roller carrier pairs preferably have a maximum distance of 50 m in order to avoid excessive slack of the carrying cable and the traction cable during the transport of the two cables to the other overhead line pole.
- the upper roller elements are preferably identical with the lower double roller elements, in order to simplify the assembly and to keep the number of different components as small as possible.
- FIG. 1 shows an arrangement with two transmission towers of an energy transmission installation, with the aid of which an exemplary embodiment of the method according to the invention is explained by way of example,
- Figure 2 shows an exemplary embodiment of a roller device which is suitable for carrying out the inventive method
- FIG. 3 shows a further exemplary embodiment of a roller device, with which an optical light source in the energy transmission system according to FIG. install the conductor between two transmission towers.
- the mast top 20 is connected via a ground wire 30 with the mast top 40 of another transmission tower 50, which is the next adjacent overhead mast.
- the mast tips 20 and 40 form in the exemplary embodiments according to Figures 1 to 3 Erdseilanbmdungsstellen for connecting the two transmission lines earth wire 30; Of course, this is only to be understood as an example, since the Erdseilanbmdungsstellen can also be located at other locations than the mast tops, for example below the mast tops.
- a roller device 70 For mounting an optical waveguide, not shown in FIG. 1, between a mast point 60 of the overhead line mast 10 and a mast point 65 of the adjacent overhead mast 50, a roller device 70 is used, which is attached to the earth wire 30 and lifted off the overhead line mast 10 in the direction of the ground other transmission tower 50 moving tractor 80 communicates. With the tractor 80, an end 90 of an upper spacer cable 100 is connected, the other end 110 is connected to the mast top 20 of the transmission tower 10 in connection.
- the roller device 70 has a multiplicity of roller carrier pairs, of which five are shown by way of example in FIG. 1 and designated by reference numerals 150a, 150b, 150c, 15d and 15oe.
- the first three Rollentragerprese 150a, 150b and 150c shown in detail again in detail in Figure 2.
- the roller carrier pairs each have an upper double roller element 160 and a lower double roller element 170.
- the upper double-roller element 160 has two rollers 180 and 190, which are connected to one another via a support element 200.
- the lower double roller element 170 has a corresponding structure and has two rollers 210 and 220, which communicate with one another via a carrier element 230.
- the two carrier elements 200 and 230 of each roller carrier pair are each connected by means of an individual dielectric tether, which in FIGS. 1 and 2 is identified by reference numerals 240a, 240b, 240c, 24d or 24e.
- the function of the dielectric tethers 240a to 24Oe is, in the case of movement of the tractor 80 from the mast top 20 towards the mast top 40, the upper
- Dual roller elements 160 to couple with the lower double roller elements 170 of each pair of roller carriers, so that they are moved in pairs along the longitudinal direction of the earth cable 30 when the tractor is moved as described.
- the lower double roller elements 170 are interconnected by means of a lower spacer cable 300.
- the lower spacer cable 300 and the upper spacer cable 100 thus run at least approximately parallel to each other.
- a carrying cable 350 as well as a traction cable 360 from the mast point 60 to the mast point 65
- one end 370 of the carrying rope 350 and one end 380 of the traction cable 360 on the lower double roller element 170 of the first pair of roller carriers, as seen from the other overhead line 50 150a attached Accordingly, the tractor 80 during its movement from the mast top 20 to the mast top 40 will not only pull the upper spacer cable 90 toward the other mast 50, but also the tow rope 350 and the pull cable 360.
- the carrying rope 350 is tensioned by means of a tensioning device, so that the carrying rope 350 can assume a carrying function for the traction cable 360.
- the traction cable 360 is therefore no longer held primarily by the earth rope 30, but exclusively by the traction cable 350.
- the function of the earth rope 30 is thus restricted in this phase to a safety function which serves to secure the traction cable 350 secure, if this should tear contrary to expectations.
- the other end 400 of the pull cable 360 in FIG. 1 is connected to an optical waveguide end, not shown in FIG. 1, of an optical waveguide cable; then the other end 400 of the traction cable 360 is moved in the direction of the mast point 65 by pulling on the traction cable 360 from the mast point 65.
- the other end 400 of the traction cable 360 has reached the mast point 65, only the optical waveguide not shown in FIG. 1 is held by the lower double roller elements 170 of the roller carrier pairs 150a to 15Oe.
- the installation of the optical waveguide between the mast points 60 and 65 is thus completed, so that the roller device 70 with the upper spacer cable 90, the lower spacer cable 300 and the support cable 350 can be dismantled.
- the upper spacer cable 90, the lower spacer cable 300, the tractor 80, the roller carrier pairs 150a-e and the support cable 350 are dismantled, wherein a connection fertil of the two transmission towers 10 and 50 is maintained at the mast points 60 and 65 through the optical waveguide.
- FIG. 3 shows a further exemplary embodiment of an arrangement with which an optical waveguide can be installed between two mast points of two transmission towers.
- the roller device 70 according to FIG. 3 has other roller carrier pairs than the roller device 70 according to FIG. 2.
- emitter roller elements 600 are used, each of which has an individual dielectric tether 240a. c are connected to a lower double roller element 170, as has been shown and explained in connection with FIG.
- weight is thus saved since the lower roller 190 of the upper double-roller element 160 is dispensed with compared to the embodiment according to FIG. 2; because only a single upper roller 610 per pair of roller carriers is used.
- an optical waveguide can be mounted between two adjacent transmission towers.
- the optical waveguide can be attached to further free-form masts, which are not shown in the figures, without the optical waveguide having to be interrupted or cut for this purpose; it can be pulled in the piece over a variety of transmission towers and attached to this example.
