Abstract
The invention relates to the field of electrical engineering, more specifically to designs for overhead ground wires made by twisting steel wires with an embedded optical cable, and can be used for suspension on overhead power lines to protect against direct lightning strikes and to provide optical communication via the cables embedded in the overhead ground wire. The overhead ground wire with an optical communication cable comprises: a central tube containing optical fibres and a water-repellent filler. The tube is made from a heat-shielding and high-tensile composite material (carbon-fibre-reinforced plastic). The first layer is made up of seven wires; the second layer is made up of two alternating sets of seven steel wires; and the third layer consists of fourteen steel wires. The first, second and third layers are made of wires of different diameters with the same lay length and direction and with linear contact between the wires of the first, second and third layers, which are plastically deformed; the degree of reduction over the area of the cross-section of the ground wire is 2-4%; the area of contact between the wires in the layers is increased, and the ground wire as a whole is rendered more compact. The invention increases the resistance of the ground wire to lightning strikes, vibration and the effect of short-circuit currents and breaking load after short-circuit current testing, while enabling the optical communication cable to remain functional throughout a long service life in an overhead power line.

The invention relates to the field of electrical engineering, namely, to designs of lightning protection cables made by twisting steel wires with an integrated optical cable, and can be used for suspension on overhead power lines (OHL) to protect the OHL from direct lightning strikes and for optical communication via cables built-in into a lightning protection cable.
Известен грозозащитный трос с оптическими волокнами, содержащий оптические волокна в диэлектрических трубках, центральный силовой элемент, диэлектрическую оболочку, металлическую оболочку, броню, отличающийся тем, что внешняя поверхность металлической оболочки выполнена продольно гофрированной, а броня выполнена из повива круглых проволок, в котором соседние проволоки имеют разные механическую прочность и проводимость (см . описание изобретения к патенту РФ Ns21 14474, МПК Н01 В1 1 /22, опубликовано 27.06.1998).

Недостатками известного провода с оптическими волокнами является: The disadvantages of the known wires with optical fibers are:
- конструктивная и технологическая сложность изготовления узла в грозотросе с оптическими волокнами; - constructive and technological complexity of manufacturing a node in a ground wire with optical fibers;
- сложность конструкции по размещению оптических волокон не позволит получать стандартные типы размеры грозозащитных тросов - the complexity of the design for the placement of optical fibers will not allow to obtain standard types of sizes of lightning protection cables
- диаметры и длины, соответствующие стандартным расстояниям между опорами (ВЛ); - diameters and lengths corresponding to standard distances between supports (OHL);
данная конструкция требует дополнительного количества нестандартных элементов и соединительных узлов, что скажется на надежности всей конструкции в целом; this design requires an additional number of non-standard elements and connecting nodes, which will affect the reliability of the entire structure as a whole;
- предлагаемая конструкция брони не позволит выполнить одно из основных назначений грозозащитного троса с оптическими волокнами - the proposed armor design will not allow one of the main purposes of a lightning protection cable with optical fibers
- длительной защиты ВЛ от прямых ударов молнии из-за теплового разрушения элементов брони с уменьшенной механической прочностью;
- развитая гофрированная поверхность центрального силового элемента выполнена из металла (теплопроводного материала) способствует интенсификации передачи тепла, возникающего при ударе молнии и воздействии токов короткого замыкания, к оптическим волокнам, разрушению диэлектрических оболочек оптических волокон и потере работоспособности оптической линии связи. - long-term protection of overhead lines from direct lightning strikes due to thermal destruction of armor elements with reduced mechanical strength; - the developed corrugated surface of the central power element is made of metal (heat-conducting material) contributes to the intensification of heat transfer arising from lightning and short-circuit currents to optical fibers, the destruction of the dielectric shells of optical fibers and the loss of operability of the optical communication line.
Известен встроенный в грозозащитный трос оптический кабель связи, содержащий скрученные друг с другом оптические модули и металлические элементы, причем поверх скрутки выполнен повив из металлических проволок, отличающийся тем, что диаметр металлических элементов больше, чем диаметр оптических модулей (см. описание полезной модели к патенту РФ Ne16794, МП К G 02 В 6/44, опубликовано 10.02.2001 ). A known optical communication cable integrated in a lightning protection cable contains optical modules and metal elements twisted together, and twisted metal wires over the twist, characterized in that the diameter of the metal elements is larger than the diameter of the optical modules (see the description of the utility model for the patent RF Ne16794, MP K G 02 B 6/44, published 02/10/2001).
Недостатком известного провода является: A disadvantage of the known wire is:
- увеличение диаметра металлических проволок в верхнем повиве не является определяющим фактором в эксплуатационной стойкости грозозащитного троса с встроенным оптическим кабелем связи; - an increase in the diameter of metal wires in the upper layer is not a determining factor in the operational stability of a lightning protection cable with an integrated optical communication cable;
- данная конструкция не работоспособна из-за низкой стойкости к прямому удару молнии и воздействию ветровых вибраций; - this design is not operational due to the low resistance to direct lightning and wind vibrations;
- применение в конструкции ОКГТ проволок с большим диаметром увеличивает суммарный диаметр изделия, что неизбежно скажется на увеличении суммарной ветровой нагрузки на изделия и опоры ВЛ или, при тех же диаметрах, существенно увеличивает величину пор в поперечном сечении изделия, что снижает теплоотвод от подверженных воздействию удара молнии проволок внешнего повива к остальным проволокам, перегреву и разрушению проволок внешнего повива при каждом ударе молнии, что, при малом числе силовых элементов в конструкции , может привезти к потере устойчивости всем изделием , обрыву грозозащитного троса и оптического кабеля на ВЛ. - the use in the design of OCGT wires with a large diameter increases the total diameter of the product, which will inevitably affect the increase in the total wind load on the products and supports of overhead lines or, at the same diameters, significantly increases the pore size in the cross section of the product, which reduces heat dissipation from susceptible to impact lightning of wires of an external winding to other wires, overheating and destruction of wires of an external winding with each lightning strike, which, with a small number of power elements in the structure, can lead to sweat The stability of the whole product, the breakage of a lightning protection cable and an optical cable to the overhead line.
- рыхлая структура конструкции и малая механическая связь внешнего слоя проволок увеличенного диаметра с внутренними слоями может привести к возникновению колебаний отдельных элементов конструкции с собственной частотой и механическому их разрушению от воздействия ветровых колебаний .
Известен грозозащитный трос, содержащий центральный стальной сердечник и скрученные вокруг него два повива из стальных проволок, слоя деблокирующего материала, полимерную оболочку из композиции сшитого полиэтилена, оптическое волокно, гидрофобный заполнитель и полимерную трубку (см. описание полезной модели к патенту РФ Ns45046, МПК Н 01 В 7/10, опубликовано 10.04.2005). - the loose structure of the structure and the small mechanical connection of the outer layer of wires of increased diameter with the inner layers can lead to vibrations of individual structural elements with their own frequency and their mechanical destruction from the effects of wind vibrations. A lightning-protective cable is known that contains a central steel core and two twists of steel wires twisted around it, a layer of release material, a polymer sheath made from a cross-linked polyethylene composition, an optical fiber, a hydrophobic filler, and a polymer tube (see utility model description to RF patent Ns45046, IPC N 01 B 7/10, published on 04/10/2005).
Недостатком известного изобретения является: A disadvantage of the known invention is:
- покрытие стальных проволок полимерной оболочкой не способствует защиты от прямых ударов молнии и приводит к потере основного назначения троса. - coating steel wires with a polymer sheath does not contribute to protection against direct lightning strikes and leads to the loss of the main purpose of the cable.
Задачей заявляемого изобретения является - увеличение стойкости грозозащитного троса с оптическим кабелем связи к удару молнии, при одновременном сохранении работоспособности оптического кабеля в течение длительного срока эксплуатации в составе ВЛ и выполнении всех технических требований, влияющих на надежность воздушных линий электропередачи.

При этом первый , второй и третий повивы выполнены с одинаковым шагом свивки , в одном направлении с л инейным касанием проволок первого, второго и третьего повивов. Пластическая деформация третьего пови ва по наружным поверхностя м проволок, увеличивает площадь контакта между проволоками7 третьего повива, а также между проволоками 6, 5 и 4 и уплотняет трос в целом .

In this case, the first, second and third coils are made with the same twist pitch, in the same direction, with a linear touch of the wires of the first, second and third coils. Plastic deformation of the third wire along the outer surfaces of the wires increases the contact area between the wires 7 of the third wire and also between the wires 6, 5 and 4 and compacts the cable as a whole.
Технология изготовления грозозащитного троса сводится к следующему. The manufacturing technology of a lightning protection cable is as follows.
Свивку проволок 4; 5; 6; и 7 троса осуществляют за одну технологическую операцию на традиционном оборудовании, используемом при производстве канатов и тросов. При этом шаг свивки для всех слоев проволок 4; 5; 6 и 7 сохраняется постоя нным , допуская при этом различные углы свивки для каждого слоя проволок, при соответствующем подборе диаметров проволок по слоям , что позволяет исключить возможность перекрещивания проволок по отдельным слоям и обеспечить им линейное касан ие при свивке. A lay of wires 4; 5; 6; and 7 cables are carried out in one technological operation on traditional equipment used in the manufacture of ropes and cables. At the same time, the lay step for all layers of wires 4; 5; 6 and 7 is kept constant, while allowing different lay angles for each layer of wires, with appropriate selection of wire diameters by layers, which eliminates the possibility of crossing wires across individual layers and provides them with linear tangency during lay.

При этом выполняют пластическое обжатие внешних проволок 7 с степенью обжатия по площади сечения троса в диапазоне 2-5-4%, в резул ьтате чего, наружные поверхности проволок 7 третьего повива получаются пластически деформирован ными . Площадь контакта
между проволоками 7 третьего повива получена увеличенной, как и между проволоками 6 5 второго повива и проволоками 4 первого повива, что приводит к уплотнению троса. The second technological operation is the plastic deformation of the product, which is performed simultaneously with the twisting of the cable. In this case, plastic crimping of the outer wires 7 is performed with a degree of crimping over the cable cross-sectional area in the range of 2-5-4%, as a result of which, the outer surfaces of the third wound wires 7 are plastically deformed. Contact area between the wires 7 of the third coil, an enlarged one was obtained, as between the wires 6 5 of the second coil and the wires 4 of the first coil, which leads to a cable seal.
Заявляемое изобретение позволяет повысить стойкость грозозащитного троса с оптическим кабелем связи к удару молнии, без снижения натяжения троса и обрыва проволок при разряде, при одновременном сохранении работоспособности оптического кабеля в течение длительного срока эксплуатации в составе ВЛ и соблюдении всех технических требований, влияющих на надежность воздушных линий электропередачи.
