Description

L'invention concerne un procédé et un dispositif d'assemblage d'une tresse de liaison à une tige de contact mobile utilisée dans un pôle d'appareillage électrique haute tension. L'une des extrémités de la tresse est connectée à une plage fixe, et l'autre extrémité est raccordée à la tige au moyen d'un organe de fixation.The invention relates to a method and a device for assembling a connection braid to a movable contact rod used in a pole of high-voltage electrical equipment. One end of the braid is connected to a fixed pad, and the other end is connected to the rod by means of a fixing member.

Il est classique d'utiliser des vis de serrage destinées à appliquer une face plane de la tresse contre une surface conjuguée de la tige de contact. Cette disposition asymétrique du raccord électrique perturbe la répartition du champ électrique lorsque la tige de contact est sous tension. La tenue diélectrique de l'appareillage peut être affectée par cette répartition non uniforme du champ électrique autour du raccord en saillie, et les performances de l'appareillage restent limitées.It is conventional to use clamping screws intended to apply a flat face of the braid against a mating surface of the contact rod. This asymmetrical arrangement of the electrical connection disturbs the distribution of the electric field when the contact rod is energized. The dielectric strength of the device can be affected by this non-uniform distribution of the electric field around the protruding fitting, and the performance of the device remains limited.

L'invention a pour but de remédier à ces inconvénients et de permettre la réalisation d'un raccord fiable sans vis de fixation et à répartition uniforme du champ électrique.The object of the invention is to remedy these drawbacks and to enable a reliable connection to be made without fixing screws and with uniform distribution of the electric field.

Le procédé d'assemblage de la tresse selon l'invention est caractérisé par les étapes suivantes :

  • - on utilise une tresse composée de brins conducteurs entrelacés agencés selon un fourreau tubulaire aplati,
  • - on enfile la broche dans le fourreau par un orifice intercalaire ménagé entre des brins adjacents de manière à obtenir une surface de contact annulaire entre la tresse et la broche,
  • - et on solidarise la portion tubulaire de la tresse sur la broche au moyen d'un manchon extérieur de fixation entourant coaxialement la surface de contact annulaire.
The method of assembling the braid according to the invention is characterized by the following steps:
  • - a braid is used composed of interlaced conductive strands arranged in a flattened tubular sheath,
  • - the spindle is threaded into the sheath through an intermediate hole formed between adjacent strands so as to obtain an annular contact surface between the braid and the spindle,
  • - And the tubular portion of the braid is joined to the spindle by means of an external fixing sleeve coaxially surrounding the annular contact surface.

La pression de contact dans la surface de contact annulaire est avantageusement obtenue par sertissage mécanique du manchon sur la broche. Tout autre procédé de fixation du manchon peut bien entendu être utilisé.The contact pressure in the annular contact surface is advantageously obtained by mechanical crimping of the sleeve on the pin. Any other method of fixing the sleeve can of course be used.

Le manchon de fixation de la tresse sur la broche présente une section quelconque, notamment polygonale, circulaire ou ovale, et est réalisé au moyen d'un tube métallique, en matériau conducteur.The sleeve for fixing the braid to the spindle has any section, in particular polygonal, circular or oval, and is produced by means of a metal tube, made of conductive material.

La tresse est en contact avec une surface d'appui de la broche, ayant une section circulaire rétrécie par rapport a celle de la tige de contact. La surface d'appui est lisse ou est munie de moyens d'agrippage de la tresse lors du serrage du manchon.The braid is in contact with a bearing surface of the spindle, having a circular section narrowed relative to that of the contact rod. The bearing surface is smooth or is provided with means for gripping the braid when the sleeve is tightened.

La structure coaxiale du raccord dans la zone de connexion, et la surface de contact annulaire entre tresse et broche engendrent une répartition uniforme du champ électrique et une bonne tenue diélectrique.The coaxial structure of the fitting in the connection area, and the annular contact surface between the braid and the spindle generate a uniform distribution of the electric field and good dielectric strength.

D'autres avantages et caractéristiques ressortiront plus clairement de l'exposé qui va suivre d'un mode de mise en oeuvre de l'invention donné à titre d'exemple non limitatif et représenté au dessin annexé dans lesquel :

  • - la figure 1 est une vue en élévation d'une tige de contact équipée d'une tresse selon l'invention;
  • - la figure 2 est une vue partielle en plan de la figure 1;
  • - la figure 3 est une vue en coupe selon la ligne III-III de la figure 1.
Other advantages and characteristics will emerge more clearly from the description which follows of an embodiment of the invention given by way of nonlimiting example and represented in the appended drawing in which:
  • - Figure 1 is an elevational view of a contact rod equipped with a braid according to the invention;
  • - Figure 2 is a partial plan view of Figure 1;
  • - Figure 3 is a sectional view along line III-III of Figure 1.

Sur les figures 1 à 3, une tige de contact 10 en matériau conducteur, notamment en cuivre étamé, est formée par une broche 12 cylindrique comportant un premier élément de contact 14 à l'une de ses extrémités, et un deuxième élément de contact 17 à l'extrémité opposée. Chaque élément de contact 14, 17 peut être équipé d'une pince d'embrochage (non représentée) susceptible de coopérer avec un contact fixe conjugué. Un organe de commande de la tige de contact 10 est accouplé à une bague 16 d'arrêt solidaire de la broche 12 pour assurer le déplacement en translation axiale de la tige de contact 10.In FIGS. 1 to 3, a contact rod 10 of conductive material, in particular of tinned copper, is formed by a cylindrical pin 12 comprising a first contact element 14 at one of its ends, and a second element contact 17 at the opposite end. Each contact element 14, 17 can be equipped with a racking-in clamp (not shown) capable of cooperating with a fixed conjugate contact. A contact rod control member 10 is coupled to a stop ring 16 integral with the pin 12 to ensure the displacement in axial translation of the contact rod 10.

La liaison électrique de la broche 12 mobile avec une plage fixe (non représentée) s'opère au moyen d'un conducteur souple formé par une tresse 18. L'une 19 des extrémités de la tresse 18 est coiffée par une cosse 20 de raccordement à la plage. L'autre extrémité 21 de la tresse 18 est connectée à la broche 12 le long d'une zone intermédiaire s'étendant sur une fraction de la longueur axiale ménagée entre le premier élément de contact 14 et la bague 16 de l'organe de commande.The electrical connection of the movable spindle 12 with a fixed track (not shown) takes place by means of a flexible conductor formed by a braid 18. One of the ends of the braid 18 is capped by a connection terminal 20 to the beach. The other end 21 of the braid 18 is connected to the pin 12 along an intermediate zone extending over a fraction of the axial length provided between the first contact element 14 and the ring 16 of the control member .

La tresse 18 est conformée en fourreau aplati composé de brins entrelacés en fils conducteurs et comprenant un orifice 22 radial d'introduction de la broche 12. Entre l'ori- fixe 22 et la cosse 20, la tresse 18 est plate, et est située d'un même côté de la broche 12. Entre l'orifice 22 et l'extrémité 21, la tresse 12 est tubulaire et entoure coaxialement la surface latérale cylindrique de la broche 12 dans la zone intermédiaire de connexion dans laquelle un manchon 24 extérieur de fixation est solidarisé par sertissage à la broche 12 en emprisonnant la portion tubulaire de la tresse 18. Le manchon 24 en matériau métallique conducteur présente une section polygonale, mais toute autre forme notamment circulaire ou ovale, peut être utilisée.The braid 18 is shaped as a flattened sheath composed of strands intertwined into conductive wires and comprising a radial orifice 22 for introducing the pin 12. Between the orifice 22 and the terminal 20, the braid 18 is flat, and is located on the same side of the pin 12. Between the orifice 22 and the end 21, the braid 12 is tubular and coaxially surrounds the cylindrical lateral surface of the pin 12 in the intermediate connection zone in which an outer sleeve 24 of fixing is secured by crimping to the pin 12 by trapping the tubular portion of the braid 18. The sleeve 24 of conductive metallic material has a polygonal section, but any other shape, in particular circular or oval, can be used.

Le procédé d'assemblage de la tresse 18 sur la broche 12 s'opère de la manière suivante :

  • L'extrémité 21 ouverte de la tresse 18 est conformée en fourreau et la broche 12 cylindrique est enfilée dans le fourreau par l'orifice 22 selon le sens droite -gauche indiqué par la flèche F1 (fig. 2). La portion tubulaire de la tresse 18 est agencée circonférentiellement autour d'une surface d'appui 26 de la broche 12. Le manchon 24 de fixation est ensuite engagé sur la broche 12 du côté du premier élément de contact 14 (sens gauche-droite indiqué par la flèche F2, fig. 2), de manière à entourer coaxialement la portion tubulaire de la tresse 18. L'assemblage final de la tresse 18 sur la surface d'appui 26 de la broche 12 s'effectue par sertissage mécanique du manchon 24, ou par tout autre procédé de fixation, notamment par magnétoformage ou par soudage, permettant d'obtenir une liaison mécanique et électrique fiable. En position assemblée, l'orifice 22 de la tresse 18 est disposé coaxialement avec le manchon 24 de fixation.
The method of assembling the braid 18 on the spindle 12 operates as follows:
  • The open end 21 of the braid 18 is shaped into a sheath and the cylindrical pin 12 is threaded into the sheath through the orifice 22 in the right-left direction indicated by arrow F 1 (fig. 2). The tubular portion of the braid 18 is arranged circumferentially around a bearing surface 26 of the pin 12. The fixing sleeve 24 is then engaged on the pin 12 on the side of the first contact element 14 (left-right direction indicated by arrow F 2 , Fig. 2), so as to coaxially surround the tubular portion of the braid 18. The final assembly of the braid 18 on the bearing surface 26 of the spindle 12 is carried out by mechanical crimping of the sleeve 24, or by any other fixing method, in particular by magnetoforming or by welding, making it possible to obtain a reliable mechanical and electrical connection. In the assembled position, the orifice 22 of the braid 18 is arranged coaxially with the fixing sleeve 24.

La surface d'appui 26 venant en contact avec la portion tubulaire de la tresse 18 présente une section circulaire rétrécie dont le diamètre est légèrement inférieur à celui de la broche 12. La surface d'appui 26 cylindrique est lisse, ou peut être équipée de moyens d'agrippage, notamment des rugosités ou desrainures, destinées à améliorer le tenue mécanique en rotation et en translation de la tresse 18 lors du serrage du Manchon 24.The bearing surface 26 coming into contact with the tubular portion of the braid 18 has a narrowed circular section whose diameter is slightly less than that of the spindle 12. The cylindrical bearing surface 26 is smooth, or can be equipped with gripping means, in particular roughness or drainage, intended to improve the mechanical resistance in rotation and in translation of the braid 18 when the Sleeve 24 is tightened.

Dans la zone intermédiaire de connexion la disposition coaxiale de la tresse 18 autour de la broche 12 permet d'obtenir une surface de contact annulaire (fig. 3) autorisant une répartition uniforme du champ électrique et une bonne tenue diélectrique de l'appareillage. Il en résulte également un encombrement radial minimum au niveau de la liaison grâce à la faible épaisseur du manchon 24 de fixation.In the intermediate connection zone, the coaxial arrangement of the braid 18 around the pin 12 makes it possible to obtain an annular contact surface (FIG. 3) allowing a uniform distribution of the electric field and good dielectric strength of the apparatus. This also results in a minimum radial size at the connection thanks to the small thickness of the fixing sleeve 24.
