Abstract
Description
L'invention concerne un dispositif pour attacher des lignes aériennes, notamment des câbles de puissance à un isolateur, à l'aide d'une boucle formée d'au moins deux fils torsadés, qui sont pliés en leur milieu, dans une zone de pliage, formant deux branches torsadées afin que les câbles soient logés entre elles, la zone de pliage étant lisse et non torsadée. The invention relates to a device for attaching overhead lines, in particular power cables to an insulator, using a loop formed by at least two twisted wires, which are folded in the middle, in a bending zone. , forming two twisted branches so that the cables are housed between them, the folding area being smooth and not twisted.
Des boucles du type décrit ci-dessus sont utilisées depuis longtemps pour des lignes de transmission aériennes. Loops of the type described above have long been used for overhead transmission lines.
En conséquence, d'une manière classique, les isolateurs ' sont mis en place sur les pylones ou tours de transmission et les cables de puissance sont attachés aux isolateurs de la manière suivante: la zone de pliage de la boucle est placée sur un élément de connexion; les branches torsadées en hélice sont tressées sur un trongon des câbles et l'élément de connexion est ensuite attaché à l'isolateur correspondant, dans une saillie présentant une ouverture. Consequently, in a conventional manner, the insulators are placed on the pylons or transmission towers and the power cables are attached to the insulators in the following manner: the folding zone of the loop is placed on an element of connection; the twisted branches in a helix are braided on a section of cables and the connection element is then attached to the corresponding insulator, in a projection having an opening.
Un tel élément de connexion comprend fondamentalement deux plaques parallèles entre elles, présentant des trous axiaux réalisés à proximité de l'une de leurs extrémités, et un organe essentiellement cylindrique les reliant a proximité de l'autre extrémité, l'ensemble étant constitué d'une seule pièce moulée. Such a connection element basically comprises two plates parallel to each other, having axial holes made near one of their ends, and an essentially cylindrical member connecting them near the other end, the assembly being made up of a single molded part.
La zone du coude de la boucle est ajustée entre les plaques, sur l'organe cylindrique, et la saillie de l'isolateur est ajustée entre les deux plaques et présente une ouverture avec laquelle les trous axiaux sont alignés afin de permettre l'introduction d'une broche de fixation qui assure la solidarisation entre l'élément de connexion et l'isolateur. The bend area of the loop is adjusted between the plates, on the cylindrical member, and the protrusion of the insulator is adjusted between the two plates and has an opening with which the axial holes are aligned in order to allow the introduction of '' a fixing pin which secures the connection between the connection element and the insulator.
Malgré sa large utilisation, l'élément supplémentaire de connexion nécessaire entre la boucle et l'isolateur constitue un inconvénient. Despite its wide use, the additional connection element required between the loop and the isolator is a drawback.
L'invention a donc pour objet d'offrir un dispositif du type décrit ci-dessus, qui permette d'éliminer l'élément de connexion et de réduire ainsi sensiblement les coûts d'installation tout en assurant, néanmoins, un montage très simple et sûr. The object of the invention is therefore to provide a device of the type described above, which makes it possible to eliminate the connection element and thus significantly reduce the installation costs while ensuring, however, a very simple and sure.
Cet objet est réalisé, conformément à l'invention, par le fait que les fils de la boucle peuvent être séparés en deux groupes dans la zone du coude, une broche comprenant au moins un organe de retenue étant prévue, coopérant avec un isolateur et pouvant être introduite dans la boucle. This object is achieved, in accordance with the invention, by the fact that the wires of the loop can be separated into two groups in the elbow area, a pin comprising at least one retaining member being provided, cooperating with an insulator and being able to be introduced into the loop.
Ce dispositif conforme à l'invention peut être relié directement à l'isolateur, par séparation des fils dans la zone du coude, puis introduction de la saillie d'embottement de l'isolateur entre les fils séparés et passage de la broche à travers la boucle et dans l'ouverture de la saillie, le ou les organes de retenue assurant un montage sûr du dispositif. This device according to the invention can be connected directly to the insulator, by separation of the wires in the elbow area, then introduction of the insulator's projection projection between the separated wires and passage of the pin through the loop and in the opening of the projection, the retaining member or members ensuring safe mounting of the device.
L'invention sera décrite plus en détail en regard des dessins annexés à titre d'exemple nullement limitatif et sur lesquels:
la figure 1 est une élévation d'une boucle préformée;
la figure 2 est une coupe transversale du coudé d'une boucle à deux tiges;
. la figure 3 est une coupe du coude d'une boucle à quatre tiges;
. la figure 3a est une vue correspondant à la boucle de la figure 3, les tiges étant séparées deux à deux; et
la figure 4 est une vue en perspective montrant une boucle reliant un câble de puissance à un isolateur à l'aide du dispositif selon l'invention.The invention will be described in more detail with reference to the accompanying drawings by way of non-limiting example and in which:
Figure 1 is an elevation of a preformed loop;
Figure 2 is a cross section of the bent of a loop with two rods;
. Figure 3 is a section of the elbow of a loop with four rods;
. Figure 3a is a view corresponding to the loop of Figure 3, the rods being separated two by two; and
Figure 4 is a perspective view showing a loop connecting a power cable to an insulator using the device according to the invention.
Ainsi qu'on peut le voir sur la figure 1, la boucle 1 est composée de plusieurs fils 4, par exemple des fils d'acier galvanisé ou aluminisé , solidarisés entre eux au moyen d'un adhésif, d'une résine ou par tout autre moyen. As can be seen in FIG. 1, the loop 1 is composed of several wires 4, for example wires of galvanized or aluminized steel, joined together by means of an adhesive, a resin or by any other way.
Pour être utilisé dans un dispositif conforme à l'invention, la zone du coude de la boucle ne présente pas la forme torsadée qui caractérise les deux branches 3. To be used in a device according to the invention, the elbow area of the loop does not have the twisted shape which characterizes the two branches 3.
La figure 2 illustre uniquement la zone du coude 2 d'une boucle constituée de deux fils 4, et la figure 3 représente, d'une manière analogue, la zone 2 du coude d'une boucle à quatre fils. FIG. 2 illustrates only the zone of the elbow 2 of a loop made up of two wires 4, and FIG. 3 represents, in an analogous manner, the zone 2 of the elbow of a loop of four wires.
La figure 3a illustre la boucle de la figure 3, les fils 4 étant séparés deux à deux en formant entre eux un espace intermédiaire où sera placée la saillie 7 d'assemblage d'un isolateur 6, comme montré sur la figure 4. FIG. 3a illustrates the loop of FIG. 3, the wires 4 being separated in pairs, forming between them an intermediate space where the projection 7 for assembling an insulator 6 will be placed, as shown in FIG. 4.
Ainsi qu'on peut le voir sur cette dernière figure, l'utilisation d'un élément de connexion, du type mentionné initialement, n'est plus nécessaire. As can be seen in this last figure, the use of a connection element, of the type mentioned initially, is no longer necessary.
En conséquence, à partir d'une boucle 1 telle qu'illustrée sur la figure 1, il suffit de séparer les fils 4 de la zone 2 du coude, sans torsion, de tresser les branches 3 autour des câbles 5 de puissance (figure 4), d'introduire la saillie 7 d'emboitement de l'isolateur 6 dans l'espace formé entre les fils séparés et, finalement, d'ajuster une broche 8 à tête ronde, équipée d'anneaux 9 de sécurité et d'une goupille 10, à travers la boucle (non représentée) de la saillie 7. Consequently, from a loop 1 as illustrated in FIG. 1, it suffices to separate the wires 4 from the zone 2 of the elbow, without twisting, to braid the branches 3 around the power cables 5 (FIG. 4 ), to introduce the projection 7 for fitting the insulator 6 into the space formed between the separate wires and, finally, to adjust a spindle 8 with a round head, fitted with safety rings 9 and a pin 10, through the loop (not shown) of the projection 7.
Un embout pointu 11, présentant un sommet tourné dans la direction opposée à celle de l'isolateur 6, facilite la mise en place de la boucle 1 car, de cette manière, on obtient automatiquement une séparation des deux groupes de fils 4 en appuyant la boucle 1 contre l'embout 11. A pointed tip 11, having a top turned in the direction opposite to that of the insulator 6, facilitates the positioning of the loop 1 because, in this way, a separation of the two groups of wires 4 is automatically obtained by pressing the loop 1 against tip 11.
Bien qu'une boucle comportant un nombre pair de fil permette une meilleure répartition des forces et un meilleur comportement mécanique lorsqu'elle est attachée à un isolateur, il est évidemment possible, également, d'utiliser une boucle comportant un nombre impair de fils. Although a loop with an even number of wires allows better distribution of forces and better mechanical behavior when attached to an insulator, it is obviously also possible to use a loop with an odd number of wires.
En conséquence, ce perfectionnement, apparemment simple, apporte d'énormes avantages économiques dans l'installation de réseaux aériens, car il est possible de supprimer une-pièce (c'est-d-dire l'élément de connexion) sans cependant soulever des difficultés dans l'opération d'installation et en obtenant une attache très fiable et très sûre. Consequently, this apparently simple improvement brings enormous economic advantages in the installation of overhead networks, since it is possible to remove a part (that is to say the connecting element) without however raising difficulties in the installation operation and obtaining a very reliable and very secure fastener.
il va de soi que de nombreuses modifications peuvent être apportées au dispositif décrit et représenté sans sortir du cadre de l'invention. It goes without saying that many modifications can be made to the device described and shown without departing from the scope of the invention.
