Abstract

The device which facilitates maintenance by allowing raising of the contacts in a circuit breaker having two jaws (8,8') acting as contacts which are bridged by a conductive bar, comprises two insulated bases (1,1'), which can be separated one from the other by sliding them apart using a separating mechanism (12,15,17). Each insulated base carries contacts (7,7') which fit into the jaws (8,8') and extend upwards. The upper part of the contact is formed as spring jaws (9,9') which make contact with shaped projections (22) in the cover unit which is fitted across the contacts (9,9'). To ensure reliable connection the contacts (7,7') are wedged into the breaker contacts (8,8') by the slider (12,15,17) which uses a tapered (13) block (12) running on a screw (15,16) and forcing apart the tapered faces of the insulating bases, which are carried on rods (3,3') running in guides (4) in the base.

Description

Dispositif permettant de rehausser le niveau des contacts dans un ooupe-circuit comportant deux mâchoires servant de contact et pince-support pour la mise en place dudit dispositif
La présente invention concerne un dispositif permettant de rehausser le niveau des contacts dans un coupe-circuit comportant deux mâchoires servant de contact dont les faces frontales se font face et entre lesquelles dites mâchoires on peut embrocher un barreau horizontal conducteur.Device making it possible to raise the level of the contacts in a circuit-breaker comprising two jaws serving as contact and support clamp for the installation of said device
The present invention relates to a device making it possible to raise the level of the contacts in a circuit breaker comprising two jaws serving as contact, the front faces of which face each other and between which, said jaws, a horizontal conductive bar can be connected.

Dans des coupe-circuits connus les mâchoires sont reliées à des câbles noyés dans du brai. Or dans certaines conditions il peut s'établir un arc électrique entre les deux mâchoires qui entratne la décomposition du brai ce qui peut causer de graves accidents. C"est pourquoi il a été envisagé de rehausser le niveau des contacts pour pouvoir recouvrir le brai ainsi que les mâchoires qui dépassent dans un bon isolant qui ne permet pas la propagation de l'arc électrique et qui ne se décompose pas. In known circuit breakers, the jaws are connected to cables embedded in pitch. However under certain conditions an electric arc can be established between the two jaws which causes the decomposition of the pitch which can cause serious accidents. That is why it has been envisaged to raise the level of the contacts in order to be able to cover the pitch as well as the jaws which protrude in a good insulator which does not allow the propagation of the electric arc and which does not decompose.

I1 est connu de rehausser le niveau des contacts sans interrompre l'alimentation des câbles en disposant des contacts sur des organes conducteurs emboitables aux extrémités d'un barreau isolant et en manoeuvrant à distance ce barreau isolant pour embrocher lesdits organes. I1 is known to raise the level of the contacts without interrupting the power supply of the cables by arranging the contacts on conductive members which can be plugged in at the ends of an insulating bar and by operating this insulating bar at a distance to plug in said members.

Mais cela ne permet pas d'obtenir un positionnement fixe et définitif des organes embrochables ; en effet ceux-ci peuvent être enlevés librement par une simple traction ou peuvent sortir spontanément des mâchoires sous l'action de contraintes notamment mécaniques. However, this does not make it possible to obtain a fixed and definitive positioning of the plug-in members; in fact these can be removed freely by a simple pull or can spontaneously come out of the jaws under the action of particular mechanical stresses.

Le dispositif selon l'invention permettant d'obtenir un .positionnement fixe des parties embrochables est caractérisé en ce que ce qu'il comporte deux pièces de base isolantes pouvant être écartées l'une de l'autre en coulissant par des moyens d'écartement pour venir bloquer leur extrémité opposée contre la face frontale de la mâchoire associée chacune de ces extrémités étant munie d'un organe conducteur embrochable dans ladite mâchoire ledit organe étant surmonté d'un contact. The device according to the invention making it possible to obtain a fixed positioning of the plug-in parts is characterized in that it comprises two insulating base parts which can be separated from one another by sliding by spacing means to block their opposite end against the front face of the associated jaw, each of these ends being provided with a conductive member pluggable into said jaw, said member being surmounted by a contact.

Selon une réalisation préférentielle de l'invention chacune des extrémités est également munie d'une plaque conductrice qui vient s'appliquer contre la face frontale de la mâchoire associée. According to a preferred embodiment of the invention, each of the ends is also provided with a conductive plate which is applied against the front face of the associated jaw.

Ainsi la transmission de courant entre les mâchoires destinées à être noyées dans l'isolant et les contacts qui en dépasseront est réalisée parfaitement. Thus the transmission of current between the jaws intended to be embedded in the insulator and the contacts which will protrude therefrom is carried out perfectly.

Selon une réalisation particulièrement simple du dispositif selon l'invention les moyens d'écartement sont constitués par un coin prenant appui sur une face biseautée de chaque pièce de base ledit coin étant muni d'une vis dont la tête prend appui sur un plan fixe par rapport à la face supérieure des deux pièces de base et qui coopère avec un trou fileté vertical ménagé dans le coin de façon que lorsqu'on tourne la vis dans le sens approprié le coin monte écartant ainsi les pièces de base jusqu'à ce qu'elles se bloquent contre les faces frontales des mâchoires. According to a particularly simple embodiment of the device according to the invention, the spacing means consist of a wedge bearing on a bevelled face of each base part, said wedge being provided with a screw whose head is supported on a fixed plane by relative to the upper face of the two base parts and which cooperates with a vertical threaded hole in the corner so that when the screw is turned in the appropriate direction the corner rises, thus spreading the base parts until they lock against the front faces of the jaws.

Pour faciliter la pose on peut munir le dispositif selon l'invention d'un capot isolant dans lequel sont logées et peuvent coulisser les pièces de bases avec les organes embrochables et les contacts, ledit capot étant ouvert à sa partie supérieure pour pouvoir tourner la vis et introduire un conducteur reliant les contacts et à sa partie inférieure pour pouvoir embrocher les organes embrochables dans les mâchoires avec ledit capot à poste. To facilitate installation, the device according to the invention can be provided with an insulating cover in which the basic parts are housed and can slide with the plug-in members and the contacts, said cover being open at its upper part in order to be able to turn the screw. and introducing a conductor connecting the contacts and to its lower part so as to be able to plug the plug-in members into the jaws with said station cover.

Le capot peut être muni de moyens de guidage des pièces destinées à être embrochées sur les contacts. The cover may be provided with means for guiding the parts intended to be plugged into the contacts.

Pour mettre en place le dispositif selon l'invention on peut utiliser avantageusement une pince support comportant un manche isolant muni à son extrémité de deux organes isolants embrochables sur les contacts. To set up the device according to the invention, it is advantageously possible to use a support clamp comprising an insulating handle provided at its end with two insulating members which can be plugged into the contacts.

Lorsque les moyens d'écartements sont constitués par un coin manoeuvré par une vis, on munira de préférence la pince-support d'une tige isolante tournant à l'intérieur du manche et dont l'extrémité est munie d'une clé venant engager la tete de la vis. When the separation means are constituted by a wedge operated by a screw, the support clamp is preferably provided with an insulating rod rotating inside the handle and the end of which is provided with a key engaging the screw head.

L'invention va maintenant être décrite plus en détail en se référant à un mode de réalisation particulier cité à titre d'exemple non limitatif et représenté par des dessins annexés.  The invention will now be described in more detail with reference to a particular embodiment cited by way of nonlimiting example and shown in the accompanying drawings.

La figure 1 représente une perspective du dispositif selon l'invention. Figure 1 shows a perspective of the device according to the invention.

La figure 2 représente une vue de face du dispositif selon l'invention lorsqu'il est à poste. 2 shows a front view of the device according to the invention when it is stationary.

La figure 3 représente une pince-support permettant de mettre le dispositif selon l'invention à poste. FIG. 3 represents a support clamp making it possible to put the device according to the invention in position.

Le dispositif selon l'invention (voir figures 1 et 2) comporte deux pièces de base 1, 1' isolantes ayant une forme de parallélépipède dont une petite face serait munie d'un décrochement 2, 2'. The device according to the invention (see Figures 1 and 2) comprises two basic parts 1, 1 'insulating having the shape of a parallelepiped of which a small face would be provided with a recess 2, 2'.

La pièce 1' est munie de deux barres horizontales 3 coulissant dans deux cavités 4 ménagées dans la pièce 1. The part 1 ′ is provided with two horizontal bars 3 sliding in two cavities 4 formed in the part 1.

La pièce 1 comporte sur sa petite face 5 opposée à celle munie d'un décrochement 2, une première plaque conductrice 6 au contact de cette face et une seconde plaque conductrice 7 perpendiculaire à la première et destinée à être embrochée dans une mâchoire 8. The part 1 comprises on its small face 5 opposite to that provided with a recess 2, a first conductive plate 6 in contact with this face and a second conductive plate 7 perpendicular to the first and intended to be plugged into a jaw 8.

La seconde plaque 7 est surmontée d'une mâchoire 9. Le décrochement 2 comporte une face inclinée 10 partant de la face supérieure horizontale 11. The second plate 7 is surmounted by a jaw 9. The recess 2 comprises an inclined face 10 starting from the horizontal upper face 11.

La face inclinée 10 fait un angle compris entre 20 et 150 avec la verticale. The inclined face 10 makes an angle between 20 and 150 with the vertical.

De même la pièce 1' comporte sur sa petite face 5' opposée à celle munie d'un décrochement 2', une première plaque conductrice 6 au contact de cette face et une seconde plaque conductrice 7 perpendiculaire à la première et destinée à être embrochée dans une mâchoire 8'. Likewise, the part 1 ′ has on its small face 5 ′ opposite to that provided with a recess 2 ′, a first conductive plate 6 in contact with this face and a second conductive plate 7 perpendicular to the first and intended to be plugged into an 8 'jaw.

La seconde plaque 7' est surmontée d'une mâchoire 9. Le décrochement 2' comporte une face inclinée 10' partant de la face supérieure horizontale 11'. The second plate 7 'is surmounted by a jaw 9. The recess 2' has an inclined face 10 'starting from the horizontal upper face 11'.

La face inclinée 10' fait un angle compris entre 20 et 150 avec la verticale égal mais de sens opposé à celui fait par la face 10 avec la verticale. The inclined face 10 'makes an angle between 20 and 150 with the vertical equal but in the opposite direction to that made by the face 10 with the vertical.

Un coin 12 dont les faces opposées 13, 13' viennent s'appliquer sur les faces inclinées 10, 10' est muni d'un trou fileté vertical 14 dans lequel passe une vis 15 dont la tête 16 repose sur une couronne 17 qui elle-même repose sur les faces supérieures 11, 11'. A wedge 12, the opposite faces 13, 13 'of which are applied to the inclined faces 10, 10' is provided with a vertical threaded hole 14 through which passes a screw 15, the head 16 of which rests on a crown 17 which itself even rests on the upper faces 11, 11 '.

Ainsi, lorsqu'on tourne la vis 15 dans le sens approprié, le coin 12 monte et les pièces 1 et 1' s'écartent en coulissant l'une par rapport à l'autre. Si au départ les plaques 7, 7' ont été embrochées dans les mâchoires correspondantes 8, 8', en tournant la vis 15, on vient bloquer les plaques 6 et 6' contre les faces frontales 18, 18' des mâchoires 8 et 8'. Thus, when the screw 15 is turned in the appropriate direction, the wedge 12 rises and the parts 1 and 1 'move apart by sliding with respect to each other. If at the start the plates 7, 7 'were inserted in the corresponding jaws 8, 8', by turning the screw 15, the plates 6 and 6 'are locked against the front faces 18, 18' of the jaws 8 and 8 ' .

Le dispositif comporte un capot 19 isolant muni de petites aspérités 20, 20' venant se loger dans des rainures horizontales 21, 21' ménagées dans les faces latérales des pièces 1 et 1' ; ainsi on peut faire coulisser ces pièces à l'intérieur du capot 19. The device comprises an insulating cover 19 provided with small protrusions 20, 20 ′ which are received in horizontal grooves 21, 21 ′ formed in the lateral faces of the parts 1 and 1 ′; thus these parts can be made to slide inside the cover 19.

Ce capot 19 est ouvert à sa partie inférieure de façon à ce qu'on puisse venir embrocher les mâchoires 8 et 8'. Il est également ouvert à sa partie supérieure de façon à ce qu'on puisse manoeuvrer la tête 16 de la vis et à ce qu'on puisse embrocher un barreau conducteur reliant les mâchoires 9, 9'. This cover 19 is open at its lower part so that the jaws 8 and 8 ′ can be inserted. It is also open at its upper part so that the head 16 of the screw can be maneuvered and a conductive bar connecting the jaws 9, 9 'can be inserted.

Ce capot 19 comporte des moyens de guidage 22 du barreau conducteur destiné à relier les mâchoires 9 et 9' quand on viendra fermer le circuit. This cover 19 includes guide means 22 of the conductive bar intended to connect the jaws 9 and 9 'when the circuit is closed.

Pour mettre le dispositif en place avec une grande sécurité on peut utiliser une pince support 23 (voir figures 3 et 3') comportant un manche isolant creux 24 terminé par deux plaques isolantes 25, 25' destinées à s'embrocher dans les mâchoires 9 et 9'. A l'intérieur de ce manche 24 est disposée une tige isolante 26 terminée à une extrémité par une clé 27 s'adaptant à la. tête 16 de la vis 15 et à l'autre par une poignée 28 dépassant du manche. To put the device in place with great security, it is possible to use a support clamp 23 (see FIGS. 3 and 3 ′) comprising a hollow insulating handle 24 terminated by two insulating plates 25, 25 ′ intended to be inserted into the jaws 9 and 9 '. Inside this handle 24 is arranged an insulating rod 26 terminated at one end by a key 27 adapting to the. head 16 of screw 15 and to the other by a handle 28 projecting from the handle.

Cette tige 26 peut coulisser et tourner à l'intérieur du manche 24 et dépasse à ses deux extrémités de ce manche 24.  This rod 26 can slide and rotate inside the handle 24 and protrudes at its two ends from this handle 24.

Ainsi pour mettre en place le dispositif l'opérateur embroche les plaques isolantes 25, 25' dans les mâchoires 9 et 9'. Puis se tenant à distance en poussant le manche 24, il embroche les plaques conductrices 7, 7' dans les mâchoires 8, 8'. il pousse alors la tige 26 en la tournant de façon que la clé 27 engage la tête 16 de la vis 15. Il tourne alors la tige Jusqu'à ce que le coin ait écarté les pièces 1, 1' en bloquant les plaques conductrices 6, 6' contre les faces frontales 18, 18' des mâchoires 8 et 8'. Thus, to set up the device, the operator plugs the insulating plates 25, 25 'into the jaws 9 and 9'. Then standing at a distance by pushing the handle 24, it plugs the conductive plates 7, 7 'into the jaws 8, 8'. it then pushes the rod 26 by turning it so that the key 27 engages the head 16 of the screw 15. It then rotates the rod until the corner has separated the parts 1, 1 'by blocking the conductive plates 6 , 6 'against the front faces 18, 18' of the jaws 8 and 8 '.

L'opérateur n'a plus qu'à dégager les plaques isolantes 25, 25' des mâchoires 9, 9' pour retirer la pince-support. The operator only has to release the insulating plates 25, 25 'from the jaws 9, 9' to remove the support clamp.

Lorsque le dispositif est en place on peut noyer les pièces 1, 1' avec les plaques 6, 6' et 7, 7' dans l'isolant.  When the device is in place, parts 1, 1 'can be drowned with the plates 6, 6' and 7, 7 'in the insulation.
