Description
La présente invention concerne un interrupteur destiné à assurer la coupure dans un circuit électrique et comprenant principalement une cartouche allongée sous vide, ladite cartouche comportant une enveloppe cylindrique obturée par deux fonds et renfermant deux contacts d'arc, dont l'un, fixe, est solidaire de l'un des fonds précités tandis que l'autre, mobile, est monté à coulissement axial à l'intérieur de la cartouche entre une position de fermeture et une position de séparation des contacts entraínant la formation d'un courant d'arc, et des moyens destinés à produire un champ magnétique axial dans la zone de formation de l'arc.The present invention relates to a switch intended to ensure breaking in a circuit electric and mainly comprising an elongated vacuum cartridge, said cartridge comprising a cylindrical envelope closed by two bottoms and containing two contacts arc, one of which, fixed, is secured to one of the aforementioned funds while the other, mobile, is mounted for axial sliding inside the cartridge between a closed position and a position of separation of the contacts causing the formation of an arc current, and means for producing an axial magnetic field in the region of the arc.
On connaít plusieurs moyens pour produire un champ magnétique axial dans la zone de formation de l'arc, ce champ magnétique permettant d'augmenter le pouvoir de coupure de la cartouche en engendrant une diffusion de l'arc et en évitant toute concentration d'énergie en un point particulier.We know several ways to produce an axial magnetic field in the area of formation of the arc, this magnetic field making it possible to increase the breaking capacity of the cartridge by generating a diffusion of the arc and by avoiding any concentration of energy at a particular point.
Le brevet FR 2.677.487 de la demanderesse décrit un interrupteur électrique du genre mentionné, dans lequel le champ magnétique axial est engendré par le courant parcourant une bobine solidaire du fond de la cartouche et disposée coaxialement à cette cartouche au droit de l'intervalle de séparation des contacts d'arc.The applicant's patent FR 2,677,487 describes an electrical switch of the kind mentioned, in which the axial magnetic field is generated by the flowing current a coil integral with the bottom of the cartridge and arranged coaxially with this cartridge at right of the arcing contact separation interval.

Mais d'autres avantages et caractéristiques de l'invention apparaítront mieux dans la description détaillée qui suit et se réfère aux dessins annexés donnés uniquement à titre d'exemple et dans lesquels :
- la figure 1 illustre, dans une vue en coupe, un interrupteur à vide conforme à une réalisation particulière de l'invention;
- les figures 2, 4 et 6 illustrent respectivement, dans des vues éclatées, l'un des contacts d'arc de l'interrupteur, suivant trois réalisations différentes de l'invention;
- les figures 3, 5 et 7 illustrent respectivement, dans des vues en perspective, les deux contacts d'arc suivant les trois réalisations précitées de l'invention.
- Figure 1 illustrates, in a sectional view, a vacuum switch according to a particular embodiment of the invention;
- Figures 2, 4 and 6 respectively illustrate, in exploded views, one of the arcing contacts of the switch, according to three different embodiments of the invention;
- Figures 3, 5 and 7 respectively illustrate, in perspective views, the two arcing contacts according to the three above-mentioned embodiments of the invention.
Sur la figure 1, on voit un interrupteur I à ampoule sous vide C comprenant principalement
une enveloppe isolante 1 de forme cylindrique fermée par deux fonds métalliques 2, 3 et
renfermant deux contacts d'arc 4, 5 respectivement fixe et mobile s'étendant coaxialement
à l'intérieur de ladite enveloppe 1. L'un 4 des contacts, dit fixe, est solidaire de l'un 2 des
fonds précités 2, 3 de l'enveloppe 1, tandis que l'autre 5 des contacts, dit mobile, est
monté coulissant à travers l'autre 3 des deux fonds 2, 3. Ce contact mobile 5 est mû en
translation par un mécanisme de commande non représenté, entre une position de fermeture
autorisant le passage du courant entre les contacts 4, 5 et une position de séparation
(représentée sur la figure 1) dans laquelle un courant d'arc "c" se produit entre les contacts
4, 5 préalablement à l'obtention de la coupure.In FIG. 1, we see a vacuum bulb interrupter I comprising mainly
an insulating casing 1 of cylindrical shape closed by two
Les deux contacts d'arc 4, 5 ont la même structure et sont constitués chacun par une tige
conductrice 6, 7 comportant à l'une de ses extrémités une pièce de contact 8, 9 en forme de
disque venue de forme avec ladite tige 6, 7. Sur l'extrémité libre 8a, 9a de cette pièce en
forme de disque 8, 9 est fixée une électrode conductrice 10, 11 en forme de couronne dont
le diamètre est légèrement supérieur à celui de la pièce en forme de disque 8, 9. The two
Suivant une réalisation particulière de l'invention, les moyens utilisés pour produire un
champ magnétique axial dans la zone de formation de l'arc, comprennent des moyens M
portés par les contacts d'arc 4, 5, pour imposer au courant d'arc une trajectoire inclinée par
rapport au plan P des surfaces de contact 4a, 5a des contacts d'arc 4, 5.According to a particular embodiment of the invention, the means used to produce a
axial magnetic field in the arc formation zone, include means M
carried by the arcing
En se reportant aux figures, on voit qu'à cet effet, l'extrémité 8a, 9a de chaque pièce de
contact 8, 9 est conformée en couronne 37, ladite couronne 37 étant formée à la périphérie
des pièces de contact 8, 9 et comportant des secteurs de couronne conducteurs 12 à 23 et
des secteurs de couronne non conducteurs ou peu conducteurs 25 à 36. Sur la figure 1, qui
correspond au mode de réalisation illustré sur les figures 6 et 7, la couronne 37 de chaque
pièce 8,9 est constituée par trois secteurs conducteurs 18 à 23 et trois secteurs non
conducteurs 28, 29, 30 et 34,35,36 Les figures 2 et 3 illustrent des pièces de contact 8, 9
dont l'extrémité en forme de couronne 37 est constituée par un seul secteur de couronne
conducteur 12, 13 et un secteur de couronne isolant 25,31. Dans ce cas, comme ceci est
visible sur la figure 3, les deux secteurs conducteurs 12, 13 respectifs des deux pièces de
contact 8, 9 seront placés de manière à être diamétralement opposés. Sur les figures 4 et 5,
les pièces de contact 8, 9 comportent chacune deux secteurs conducteurs 14, 15, 16, 17 et
deux secteurs non conducteurs 26, 27 et 32,33. Les deux secteurs conducteurs 14 à 17 de
chaque pièce 8, 9 sont agencés de manière à être diamétralement opposés et les deux pièces
8, 9 sont agencées l'une par rapport à l'autre de façon que les deux diamètres d, e, selon
lesquels les secteurs sont placés sur les deux pièces 8, 9 soient perpendiculaires. Sur les
figures 6 et 7, les secteurs conducteurs 18 à 23 et les secteurs non conducteurs 28, 29, 30
et 34, 35, 36 sont au nombre de trois et sont équidistants, les secteurs conducteurs 18 à 23
des deux pièces 8, 9 étant agencés de manière à être décalés angulairement.
Le fonctionnement de l'interrupteur dans ses trois formes de réalisation va être décrit
brièvement à travers ce qui suit en référence aux figures.Referring to the figures, it can be seen that for this purpose, the
The operation of the switch in its three embodiments will be described briefly through the following with reference to the figures.
En position fermée de l'interrupteur I, pour passer du contact fixe 4 au contact mobile 5, le
courant traverse successivement la tige 6 du contact fixe 4, la pièce de contact 8, les
secteurs conducteurs, l'électrode 10 du contact fixe 4, puis l'électrode 11 du contact mobile
5, les secteurs conducteurs du contact mobile 5, la pièce de contact 9 et la tige du contact
mobile 7.
En position de séparation des contacts d'arc 4, 5 préalablement à la coupure, le courant
acheminé par la tige 6 du contact d'arc fixe 4 traverse la pièce de contact 8 du contact d'arc
fixe 4 puis atteint les secteurs conducteurs. Suivant la réalisation illustrée sur les figures 2
et 3, le courant d'arc "c" passe du secteur de couronne 12 associé au contact fixe 4 au
secteur de couronne 13 associé au contact mobile 5, en passant par les électrodes 10, 11
suivant une trajectoire inclinée telle que représentée en pointillés sur la figure 3. La
composante horizontale de ce courant, c'est-à-dire parallèle aux surfaces de contact 4a, Sa
des contacts d'arc 4, 5, génère alors un champ axial localisé, permettant l'obtention, par le
maintien de plusieurs petits arcs, d'une diffusion de l'arc.In the closed position of the switch I, to pass from the
In the separation position of the
Lorsque les secteurs sont au nombre de deux ou de trois par pièce de contact, comme illustré sur les figures 4 à 7, on obtient plusieurs courants d'arc de direction inclinée par rapport aux mêmes surfaces de contact, d'où il résulte la création d'un champ magnétique axial.When there are two or three sectors per contact piece, as illustrated in FIGS. 4 to 7, several arc currents of inclined direction are obtained by compared to the same contact surfaces, from which it results in the creation of a magnetic field axial.
On notera que la tige 6, 7, la pièce de contact 8, 9 ainsi que les secteurs conducteurs 12 à
23 de chaque contact d'arc 4, 5 formant avantageusement un ensemble monobloc, seront de
préférence réalisés en cuivre. Les électrodes 10, 11 seront avantageusement réalisées en un
matériau conducteur à base de chrome et de cuivre, tandis que les secteurs non conducteurs
25 à 36 seront réalisés en un matériau isolant ou bien réfractaire.It will be noted that the
On a donc réalisé grâce à l'invention un interrupteur électrique, notamment sous vide, réalisant la coupure en champ axial, de conception particulièrement simple puisqu'il ne nécessite pas de moyens additionnels de production d'un champ axial et que la géométrie et donc la structure des contacts d'arc restent particulièrement simples.Thanks to the invention, an electrical switch has therefore been produced, in particular under vacuum, cutting in the axial field, of particularly simple design since it does not requires no additional means of producing an axial field and that the geometry and therefore the structure of the arcing contacts remains particularly simple.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemple. C'est ainsi par exemple que l'on pourrait envisager que les secteurs conducteurs soient réalisés sur les électrodes plutôt que sur les pièces de contact. De même, on pourrait supprimer les secteurs non conducteurs, surtout dans le cas ou chaque pièce de contact comporte au moins deux secteurs conducteurs.Of course, the invention is not limited to the embodiments described and illustrated which have been given by way of example only. This is how, for example, we could consider that the conductive sectors are made on the electrodes rather than on the pieces of contact. Similarly, we could remove the non-conductive sectors, especially in the case or each contact piece comprises at least two conductive sectors.
