Description

The invention relates to electrical engineering, specifically to overhead power lines and methods for their construction.

Known overhead power transmission line, including foundations, high-rise supports with traverses, on which electrical insulators are placed with multicore current-carrying wires suspended by tension and supporting clamps, while current-carrying wires are made of a combination of aluminum and steel wires, from which a core and a multicore external wire are formed (see Handbook of electrical installations of high voltage. M: Energoizdat, 1981, pp. 344-426).

Known overhead power transmission line, including a large span between the supports when crossing a wide natural obstacle, foundations with mounted anchor high-rise supports with traverses, on which electrical insulators, tension and support clamps are suspended, in which live conductors are mounted (see Patent RU 2360345) .

There is a known method of constructing an overhead power transmission line, including mounting foundations, erecting high-altitude anchor supports with traverses on them, suspending insulators, tension and support clamps, mounting devices for pulling a leader cable and multicore current-carrying wires (see ibid., Patent RU 2360345).

The disadvantages of the known overhead power transmission lines and methods of their construction are the increased material consumption of the current-carrying wires per unit voltage and the design power of the line, which is due to the relatively low efficiency of electric power transport, as well as the increased labor intensity and low reliability, which does not provide damage to the current-carrying wires during their drawing, transfer and fixing clamps of supports during installation and subsequent operation.

The problem solved by the invention is to develop a constructive system and technology for the construction of an overhead power line with phase high-temperature composite electric wires, which ensures maximum damage to the electrical wires, including their protective shells and the integrity of the multi-core structure at all stages of preparation, laying of wires and subsequent operation of the power line.

The problem in terms of the method of construction of a high-voltage overhead power transmission line is solved by the fact that the line is erected on high-rise supports with the placement of a current-carrying part on them, including at least one phase high-temperature electrical wire containing a core with at least one composite core and multi-core external wire moreover, work on the construction of the line is carried out on a construction site with a length equal to the length of the specified line or part thereof; for this, the route of the line being built is prepared, also the foundations, high-rise supports, equip the head and end construction and installation sites, respectively, in front of the first and the last support, on the first of which an aggregate such as a rolling goat is installed in series with rigid fixation, having a brake and an axle for hanging a drum with an electric wire, individual length , not less than the full anchor construction length of the mentioned construction and installation site, and also install a brake machine with the possibility of perceiving the load from the tension of the electric wire, about s of said unit a vertical plane normal to the line of flight of an erected, a drum is mounted on the axle, with the upper rolling and vanishing point above the electric wire from the reel hinge axis; on another of the aforementioned sites, a tensioning machine is likewise mounted, with the possibility of hanging a drum with a leader cable on it; both braking and tensioning machines are placed on these sites with the possibility of supplying the electric wire to the first and leaving the last support at an angle to the horizon α≤30 °, while using individual electric wires for a given construction and installation section — not less than the full anchor construction length of the specified section , similarly, the leader cable is adopted by the total or cumulative length of at least the mentioned individual length of the electric wire; high-rise supports are mounted with traverses designed in compliance with the conditions for minimizing the interaction of operational electromagnetic fields of electrical wires, at least to an acceptable level; install electrical insulators on the traverses and hang tension and / or supporting clamps for electrical wires to them, observing the condition of their greatest mutual distance in the traverse field of the support; set end and intermediate rolling rollers, which for this purpose are made with a profiled bed, at least the outer contact layer of which is made of elastically deformable material with a hardness lower than the hardness of the outer layer of the wires of the external coil of the electric wire by an amount sufficient to ensure installation and technological damage of the electric wire when contact with the specified bed, the working profile of which is adopted by the depth and width exceeding the overall cross-sectional diameter of the laid electric cables; they are passed through the expansion rollers in the direction to the leader-leader site of the cable, connect it at one end to the electric wire being laid at the outlet of the brake machine, and fasten the other end to the tension machine and lay the electric wire along the expansion rollers with a technological tension of not more than 0 , 7 on the tensile strength of the electric wire and the minimum bending radius on the rollers, the radius of which takes at least 40 overall diameters of the electric wire; after which, under technological tension, each electrical wire is reassigned and fixed in operational tension and / or supporting clamps.

The minimum bending radius of the electric wire on the rolling rollers when erecting an overhead power transmission line on high-rise supports, with at least one turn in plan at an angle α in the range of 5 ° <α≤60 °, can be achieved by using rollers with a diameter along the bottom of the bed of the rolling roller less than 60 overall diameters of the electric wire, while, as an elastically deformable layer, the bed of rollers can be made, for example, rubberized, and in the presence of one or more angular supports with an angle of rotation of more than 60 °, rollers can be used in a similar enii, with a minimum diameter of at least 1000 mm, or apply tandems of two or more rollers damaging electrically bed, tandem with fastening to a support through one point.

For laying an electric wire, a low-twisted rope with parallel-laid supporting strands in a protective sheath or in a tubular cross-stitch jacket having a length corresponding to the construction length of the electric cable plus at least six heights to the point of suspension of the specified electric cable can be used as a leader cable.

A stranded cross-stitch braided metal cable can be used as a leader cable, while installation of a leader cable can only be done on a disconnected overhead line, and the leader cable in areas near the brake and / or tensioning machine can be equipped with a roller ground electrode.

A drum with a leader cable can be placed on a tensioning machine and feed the specified cable to the installation site in reverse mode, pulling it with a tensioning, for example hydraulic, mechanism, and under minimum tension can be fed onto the rolling rollers, connecting after laying with the end of the electric wire at the brake machine.

The connection of the end of the electric wire with the leader cable can be performed through the swivel, the mounting loop and the mounting stocking in the form of a cross braid made of soft wire and a strip of protective tape that prevents damage to the end section of the electric wire.

The pulling of the electric wire can begin at a minimum speed of 5 m / min, and after passing the first support of the power line, they can increase the speed of the pull up to 100 m / min, while at the beginning of the process they can turn on the braking machine, which starts releasing the wire, increasing the sag , after that they can turn on the tensioning machine and make a broach.

Installation work on the laying of the electric wire can be performed using a tensioning machine, which is equipped with a winch with a smoothly varying speed of pulling, a reverse device, a device for varying traction, a limiter of the set maximum tension and a capstan, while the capstan can have a diameter less than the diameter of the drum of the brake machine and be designed only for winding the leader cable.

The brake machine can be equipped with a device for continuously adjusting the braking force, which ensures the regulation of the tension and the sag of the electric wire, moreover, the specified machine can be equipped with a double brake drum with a diameter exceeding the minimum allowed by the condition of non-destructive bending of the electric wire containing composite conductors; at the same time, the operation of the brake and tensioning machines can be automatically coordinated with the provision of the required tension in the entire permissible range of speeds for pulling the electric wire.

The transfer of the electric wire from the roller to the operational tension and / or supporting clamps can be carried out by means of a mounting beam with a winch. After installation in service clamps, the electric wire can be equipped with a vibration damper. A high voltage overhead power line can be erected with a voltage of 10-0.4 kW. In addition, a high-voltage overhead power line can be erected with a high-voltage voltage of 35-330 kW class.

At the same time, when constructing high-voltage overhead power transmission lines with a voltage of 10–0.4 kW to a high-voltage voltage of class 35–330 kW and above, multicore high-temperature composite electric wires can be used with wires of the type manufactured by LUMPI-BERNDORF.

The problem in part of the second object of the invention is solved in that the high-voltage overhead power line contains elevated towers erected on foundations with traverses, on which electrical insulators are mounted with multi-core current-carrying wires suspended from them by tension and support clamps, and lightning protection wires and fittings are mounted, including vibration dampers, moreover, high-temperature composite wires, each of which contains a heart, are adopted as multicore current-carrying nickname with at least one composite core and multi-core external wire, and the specified line is made according to any one of items 1-14 of the method of construction of a high-voltage overhead power line.

The technical result achieved by the invention is to develop a set of technological operations and design solutions of technological equipment for use in the construction of high-voltage overhead power lines with the greatest damage to high-temperature composite electrical wires, both from installation and operational impacts, which is achieved by the set developed in the invention assembly machines, assemblies, methods of their work, parameters of electrical wires and details about orudovaniya with which they interact with the laying and operation as part of high-voltage overhead power lines.

Preservation of high-performance characteristics of the mounted electrical wires is also achieved by their seamless execution within the assembly area of the high-voltage overhead power transmission line, by pulling them in compliance with the allowable tension and bending angles for the brakes of the brake machine and the rolling rollers.

The safety of the sheaths and the entire construction of the wire also increases the introduction of an elastic flexible layer in the elements of equipment and suspension with which the wire is in contact at all stages of installation and operation as part of a high-voltage overhead power transmission line.

The invention is illustrated by drawings, where:

A high-voltage overhead line 1 is erected on high-rise supports 2 with the placement of a current-carrying part on them, including at least one phase high-temperature electrical wire 3 containing a core with at least one composite core and a multi-core external wire (not shown conditionally). Work on the construction of line 1 is carried out on the construction site with a length equal to the length of the specified line or part thereof. To do this, prepare the route of the erected line, install the foundations, equip the front 4 and the final construction and installation sites 5, respectively, before the first and last support 2, on the first platform 4, an assembly 6 of a rolling goat type having a brake and axis 7 for hitching the drum 8 with an electric wire 3 of individual length, not less than the full anchor construction length of the mentioned construction site. A brake machine 9 is also installed there with the possibility of absorbing the load from the tension of the electric wire 3. In this case, the axis of the rolling unit 6 is positioned normally to the vertical plane of the span of the constructed line 1. The drum 8 is hung on the axis 7 with the possibility of upper rolling and with the vanishing point of the electric wire 3 from the drum 8 above the hinge axis. On the site 5, a tensioning machine 10 is similarly mounted, with the possibility of hanging a drum 11 with a leader cable 12. The two brake machines 9 and the tensioning 10 are located on the indicated platforms 4 and 5 with the possibility of supplying the electric wire to the first one and leaving the last support at an angle to horizon α≤30 °, while using an electric wire 3 individual for a given construction section of a length not less than the full anchor construction length of the specified section. Similarly, the leader cable 12 is received with the total or cumulative length of at least the mentioned individual length of the electric wire 3. The high-rise supports 2 are mounted with traverses 13 designed with the condition of minimizing the interaction of operational electromagnetic fields of the electric wires 3, at least to an acceptable level. Electrical tracers 13 are mounted on traverses 13 and suspended to them are tension 14 and / or supporting clamps 15 for electrical wires 3, observing the condition of their greatest mutual distance in the traverse field of the support. Set the end 16 and intermediate 17 rolling rollers, which for this purpose are made with a profiled bed 18, at least the outer contact layer 19 of which is made of elastically deformable material with a hardness lower than the hardness of the outer layer of the wires of the external coil of the electric wire 3 by an amount sufficient to ensure installation -technological damage to the electric wire 3 when in contact with the specified bed 18. On the rolling rollers 16, 17 in the direction of the head 4 of the construction site, the leader cable 12 is pulled, connect it at one end with a laid electrical wire 3 at the outlet of the latter from the brake machine 9, and fasten the other end to a tensioning machine 10 and lay the electrical wire along the rolling rollers 16, 17 with a process tension of not more than 0.7 of the tensile strength of electric wire 3 and a minimum with a bending radius on the rollers 16, 17. The diameter of the rollers 16, 17 along the bottom of the bed 18 is taken at least 40 overall diameters of the electric wire 3. After that, under the technological tension, the relocation and fixing of each electric wire ode 3 in operational tensioning 14 and supporting clamps 15. The minimum bending radius of the electric wire 3 on the expansion rollers is 16.17 when the overhead power line 1 is erected on the high-rise towers 2 with at least one turn in plan at an angle α in the range 5 ° <α≤ 60 °, provide, using rollers with a diameter on the bottom of the bed 18 of the expansion roller 16.17, comprising at least 60 overall diameters of the electric wire 3. In this case, the elastically deformable layer of the bed of the rollers 16, 17 is performed, for example, rubberized or polyurethane. And in the presence of one or more angular supports of line 1 with an angle of rotation in the plan of more than 60 °, rolling rollers are used in a similar design with a minimum diameter of at least 1000 mm, or tandems of two or more rollers with a non-damaging electrical wire 3 bed 18, with fastening tandem to support 2 through one point. To lay the electric wire 3, a low-twist rope with parallel-laid supporting strands in a protective sheath or in a cross-section tubular shirt, having a length corresponding to the construction length of the electric wire plus at least six heights to the point of suspension of the specified electric wire, is used as a leader cable 12. As a leader cable 12, a multi-strand braided metal cable of the cross lay is used, while installation of the leader cable is carried out only on the disconnected overhead line 1, and the leader cable 12 in areas near the brake 9 and / or tension 10 of the machine is equipped with a grounding conductor. The drum 11 with the leader cable 12 is placed on the tensioning machine 10 and serves the specified leader cable to the installation site in reverse mode, pulling it with a tension, for example, a hydraulic mechanism, and under minimum tension is fed to the rolling rollers 16, 17, connecting after laying with the end of the electric wire 3 of the brake machine 9. The end of the electric wire 3 is connected to the leader cable 12 through the swivel 20, the mounting loop 21 and the mounting stocking 22 in the form of a cross braid of soft wire and a strip of protective tape that prevents damage near the end of the electric wire 3. The pulling of the electric wire 3 is started at a minimum speed of 5 m / min, and after passing the first support 2 of the power transmission line 1, the broaching speed is increased to 100 m / min, and at the beginning of the process, the brake machine 9 is turned on, which starts to release the wire 3, increasing the sag, then turn on the tension machine 10 and produce a broach. Installation work on the laying of electric wire 3 is performed using a tension machine 10, which is equipped with a winch with a varying speed of pulling, a reverse device, a device for smoothly varying traction, a limiter of a given maximum tension and a capstan, while the capstan has a diameter less than the diameter of the drum of the brake machine 9 and is designed for winding only the leader cable 12. The brake machine 9 can be equipped with a device for smooth regulation of the braking force, which provides tension control Ia and sag electric wire 3 and 9 wherein said machine is equipped with a dual brake drum with a diameter greater than the minimum allowable condition for nondestructive bending the electric wire 3 having composite core. The operation of the brake 9 and the tension 10 of the machines is automatically coordinated with ensuring the required tension in the entire permissible range of speeds for pulling the electric wire 3. The transfer of the electric wire 3 from the rollers 16, 17 to the operational tension 14 and / or supporting 15 clamps is carried out by means of a mounting beam 23 with a winch 24. After installation in operational clamps 14, 15, the electric wire 3 is equipped with a vibration damper. An overhead power line can be built with a voltage of 10-0.4 kW. In addition, the overhead power line can be erected with a high voltage voltage of class 35-330 kW.
