Description
Condensateur triphasé sec enrobé de résine
La présente invention concerne un condensateur sec enrobé de résine.Resin-coated dry three-phase capacitor
The present invention relates to a dry resin-coated capacitor.
Il est connu d'utiliser des condensateurs pour améliorer le cos Y sur les réseaux de distribution publique ou privée. On connaît un condensateur sec triphasé destiné à cet usage qui est composé de trois éléments de condensateur connectés en triangle, les éléments de condensateur étant cylindriques et constitués par des bobinages en film de polyoléfine métallisé. Les trois éléments de condensateur sont placés côte à côte et après la réalisation des connexions, l'ensemble est enrobé dans une résine, d'où il ne sort que les trois bornes de connexion. It is known to use capacitors to improve the cos Y on public or private distribution networks. There is a known three-phase dry capacitor intended for this use which is composed of three capacitor elements connected in a triangle, the capacitor elements being cylindrical and constituted by windings in metallized polyolefin film. The three capacitor elements are placed side by side and after making the connections, the assembly is coated in a resin, from which only the three connection terminals come out.
Selon les besoins de puissance réactive nécessaire, on peut assembler plusieurs condensateurs. L'assemblage se fait sur une semelle, les condensateurs étant fixés sur cette semelle. Depending on the required reactive power requirements, several capacitors can be assembled. The assembly is done on a sole, the capacitors being fixed on this sole.
Lors de l'enrobage, on utilise un moule ; l'invention a pour but de supprimer le moule donc les opérations de démoulage, nettoyage du moule, graissage etc et propose d'utiliser une botte en matériau synthétique moulable dans laquelle est placé le condensateur et servant de moule définitif pour la résine. Cette botte est alors agencée de manière à permettre un assemblage facile de plusieurs bottes entre elles. Par ailleurs, au lieu de réaliser les connexions entre les trois éléments de condensateur par des conducteurs soudés comme on le fait actuellement, on propose de les réaliser au moyen d'une carte de circuit imprimé, les soudures étant réalisées industriellement à la vague.On profite alors de la présence de la botte et de la carte pour réaliser un calage du condensateur lors de l'opération d'enrobage, au moyen de glissières prévues sur deux parois latérales internes de la botte et dans lesquelles vient s'enficher la carte solidaire de ses trois éléments de condensateur. During the coating, a mold is used; the invention aims to remove the mold therefore the release operations, mold cleaning, lubrication etc. and proposes to use a boot made of moldable synthetic material in which the capacitor is placed and serving as a final mold for the resin. This boot is then arranged so as to allow easy assembly of several boots together. Furthermore, instead of making the connections between the three capacitor elements by soldered conductors as is currently the case, it is proposed to make them by means of a printed circuit board, the soldering being carried out industrially by wave. Take advantage of the presence of the boot and the card to wedge the capacitor during the coating operation, by means of slides provided on two internal side walls of the boot and in which the integral card is inserted. of its three capacitor elements.
La présente invention a donc pour objet un condensateur triphasé, sec, enrobé de résine, composé de trois éléments cylindriques de condensateur mis côte à côte, caractérisé en ce que les connexions entre les trois éléments du condensateur triphasé sont réalisées par l'intermédiaire d'une carte de circuit imprimé placée contre lesdits éléments parallèlement à leur axe et en ce que le condensateur, muni de sa carte est placé dans une botte en matériau synthétique moulable, une résine remplissant l'espace libre entre le condensateur et la boite, celle-ci comportant des éléments permettant l'assemblage de plusieurs bottes. The present invention therefore relates to a three-phase, dry capacitor, coated with resin, composed of three cylindrical elements of capacitor placed side by side, characterized in that the connections between the three elements of the three-phase capacitor are made by means of a printed circuit board placed against said elements parallel to their axis and in that the capacitor, provided with its card is placed in a boot made of moldable synthetic material, a resin filling the free space between the capacitor and the box, Ci comprising elements allowing the assembly of several boots.
Selon une réalisation particulièrement avantageuse de l'invention ladite carte est prise entre deux glissières latérales internes de la boite. According to a particularly advantageous embodiment of the invention, said card is taken between two internal lateral slides of the box.
Selon une autre caractéristique de l'invention, la botte comporte deux bossages internes du côté opposé à ladite carte, ces bossages étant situés l'un entre le premier élément du condensateur et celui du milieu et l'autre entre celui du milieu et le troisième, ces bossages réalisant un calage des éléments de condensateur lors de la coulée de la résine. According to another characteristic of the invention, the boot has two internal bosses on the side opposite to said card, these bosses being located one between the first element of the capacitor and that of the middle and the other between that of the middle and the third , these bosses making a setting of the capacitor elements during the casting of the resin.
On va maintenant décrire un exemple de réalisation de l'invention en référence au dessin annexé dans lequel
La figure 1 est une perspective éclatée du condensateur selon l'invention.We will now describe an embodiment of the invention with reference to the accompanying drawing in which
Figure 1 is an exploded perspective of the capacitor according to the invention.
La figure 2 montre en demi-coupe vue de face en éclatée, la boite vide dans laquelle doivent être placés les éléments de condensateur. Figure 2 shows in half-section exploded front view, the empty box in which the capacitor elements must be placed.
La figure 3 est une coupe selon III-III de la figure 2 mais les trois pièces de la boite étant assemblées. Figure 3 is a section on III-III of Figure 2 but the three parts of the box being assembled.
La figure 4 est une coupe selon IV-IV de la figure 2 dans laquelle on a représenté schématiquement deux des trois éléments de condensateur et une portion de la carte de circuit imprimé. Figure 4 is a section on IV-IV of Figure 2 in which there is shown schematically two of the three capacitor elements and a portion of the printed circuit board.
En se reportant maintenant aux figures, on voit que le condensateur triphasé selon l'invention comprend trois éléments de condensateur 1, 2 et 3. Les connexions sont réalisées par le moyen d'une carte 4 comportant un circuit électrique imprimé 5. Les éléments de condensateur sont reliés au circuit imprimé de la carte par des soudures faites par exemple par le procédé dit " à la vague". L'ensemble des trois éléments 1, 2, 3 de condensateur avec sa carte 4 est placé à l'intérieur d'une boite 6. Cette botte sert de moule définitif pour la coulée d'une résine d'enrobage. Cette boite est en un matériau isolant électrique moulable et comporte en son intérieur des glissières latérales 7 et 8, et deux bossages 9 et 10.Lors de l'introduction de l'ensemble comprenant la carte 4 avec les trois éléments 1, 2 et 3 de condensateur, dans la botte 6, la carte 4 est glissée entre les deux glissières 7 et 8, le bossage 9 vient se placer entre ltélément 2 et l'élément 3 et le bossage 10 entre l'élément 2 et l'élément 1. Glissières et bossages réalisent ainsi une mise en place et un calage de l'ensemble dans la botte en leur assurant une bonne position pour l'opération de coulée de la résine d'enrobage. Referring now to the figures, it can be seen that the three-phase capacitor according to the invention comprises three capacitor elements 1, 2 and 3. The connections are made by means of a card 4 comprising a printed electrical circuit 5. The elements of capacitor are connected to the printed circuit of the card by solderings made for example by the process called "wave". The set of three elements 1, 2, 3 of capacitor with its card 4 is placed inside a box 6. This boot serves as a final mold for the casting of a coating resin. This box is made of a moldable electrical insulating material and has inside its side rails 7 and 8, and two bosses 9 and 10. When introducing the assembly comprising the card 4 with the three elements 1, 2 and 3 of capacitor, in the boot 6, the card 4 is slid between the two slides 7 and 8, the boss 9 is placed between the element 2 and the element 3 and the boss 10 between the element 2 and the element 1. Slides and bosses thus set up and wedge the assembly in the boot, ensuring that they are in a good position for the coating resin casting operation.
Après avoir introduit la carte avec ses trois éléments de condensateur, on ferme avec un couvercle 11, celui-ci vient s'appuyer contre la partie supérieure des glissières 7 et 8 et contre la partie supérieure de renforts 12 et 13, les extrémités 15et 16 du couvercle s'engageant sous des bourrelets 17 et 18 situés à la partie supérieure de la botte. Le couvercle 11 possède trois trous 19, 20 et 21 pour le passage des bornes des éléments de condensateur 1, 2 et 3. Ces trous sont réalisés de telle façon qu'ils comportent des bords en forme de languettes venant se placer dans une gorge 19 prévue sur les bornes filetées, ainsi, de cette façon et grâce aussi aux bourrelets 17 et 18, le couvercle est bien maintenu sur la botte 6. Le couvercle 11 possède encore deux ouvertures 22 et 23 à bords surélevés en forme de parallélépipède rectangle servant à la coulée de la résine d'enrobage. Une fois la coulée réalisée, l'ensemble est fermé par un capot 24 fixé par des vis passant dans des trous 25 et 26 et se vissant dans des trous taraudés réalisés dans des tétons 27 et 28 du couvercle. Le capot 24 comporte des découpes 29, 30, 31, 32, 33, 34 permettant de laisser passer des barrettes de connexion telles que la barrette 35. After having introduced the card with its three capacitor elements, it is closed with a cover 11, which rests against the upper part of the slides 7 and 8 and against the upper part of reinforcements 12 and 13, the ends 15 and 16 of the cover engaging under beads 17 and 18 located at the upper part of the boot. The cover 11 has three holes 19, 20 and 21 for the passage of the terminals of the capacitor elements 1, 2 and 3. These holes are made in such a way that they have edges in the form of tongues which are placed in a groove 19 provided on the threaded terminals, thus, in this way and also thanks to the beads 17 and 18, the cover is securely held on the boot 6. The cover 11 still has two openings 22 and 23 with raised edges in the shape of a rectangular parallelepiped used for casting the coating resin. Once the casting has been carried out, the assembly is closed by a cover 24 fixed by screws passing through holes 25 and 26 and being screwed into tapped holes made in pins 27 and 28 of the cover. The cover 24 has cutouts 29, 30, 31, 32, 33, 34 allowing passage of connection bars such as the bar 35.
Les bottes 6 comportent en outre des organes d'embottement complémentaires tels que les bossages 36 et les évidements 37 permettant d'assembler plusieurs condensateurs comme le montre la figure 1. The boots 6 also include complementary booting members such as the bosses 36 and the recesses 37 making it possible to assemble several capacitors as shown in FIG. 1.
L'assemblage est lié grâce à des tirants passant dans des trous 38 réalisés dans des bossages 39 situés à la base des bottes. The assembly is linked by tie rods passing through holes 38 made in bosses 39 located at the base of the boots.
