Description

DISPOSITIF DE SURVEILLANCE THERMIQUE DE SECURITE POUR CONNEXIONS D'INSTALLATIONS ELECTRIQUES THERMAL SAFETY MONITORING DEVICE FOR ELECTRICAL INSTALLATION CONNECTIONS
La présente invention concerne un dispositif de surveillance thermique pour installation électrique et plus particulièrement un dispositif sensible à réchauffement subi par une connexion.The present invention relates to a thermal monitoring device for electrical installation and more particularly to a device sensitive to heating undergone by a connection.
On sait que les installations électriques sont munies de différents dispositifs de sécurité et notamment de dispositifs sensibles aux augmentations de l'intensité parcourant un circuit (fusibles et disjoncteurs) et des dispositifs de détection de fuite de courant par la terre (dispositifs différentiels) .It is known that electrical installations are provided with various safety devices and in particular with devices sensitive to increases in the intensity flowing through a circuit (fuses and circuit breakers) and devices for detecting current leaks from the ground (differential devices).
L'expérience a cependant montré que nombre de sinistres ont été provoqués par réchauffement de connexions en mauvais état. Or ces défauts de connexion ne sont pas protégés par les dispositifs de sécurité actuels et sont quasiment indétectables aussi bien par les électriciens que par les bureaux de contrôle lors notamment de la réception des ouvrages. Ce risque est d'autant plus important que la qualité des connexions ne peut que se détériorer au cours du temps.However, experience has shown that a number of claims have been caused by the heating up of poor connections. However, these connection faults are not protected by current security devices and are almost undetectable both by electricians and by control offices during reception of the works in particular. This risk is all the more important since the quality of the connections can only deteriorate over time.
La présente invention a pour but de remédier à ces inconvénients en proposant un dispositif de surveillance thermique qui est sensible à réchauffement produit par une connexion défectueuse.The present invention aims to remedy these drawbacks by proposing a thermal monitoring device which is sensitive to heating produced by a defective connection.
La présente invention a ainsi pour objet un dispositif de surveillance thermique d'une connexion d'une installation électrique, caractérisé en ce qu'il comporte un premier élément de liaison en relation thermique et électrique avec une connexion à surveiller, un second élément de liaison en relation électrique avec la mise à la terre de l'installation, des moyens de connexion électrique qui allient entre eux les deux moyens de liaison, et qui sont susceptibles d'occuper deux états, a savoir un premier état ou état normal de fonctionnement dans lequel ils sont isolants électriquement et un second état ou état de rupture, dans lequel ils deviennent électriquement conducteurs lorsqu'ils atteignent une température critiqueThe present invention thus relates to a device for thermal monitoring of a connection of an electrical installation, characterized in that it comprises a first connection element in thermal and electrical relation with a connection to be monitored, a second connection element in electrical connection with the earthing of the installation, electrical connection means which combine the two connecting means, and which are capable of occupying two states, namely a first state or normal operating state in which they are electrically insulating and a second state or rupture state, in which they become electrically conductive when they reach a critical temperature
Dans un mode de mise en oeuvre de l'invention les moyens de connexion électriques sont tels que lorsqu ils atteignent la température- critique ils passent, de façon irréversible d'un état non conducteur a un état conducteurIn one embodiment of the invention, the electrical connection means are such that when they reach the critical temperature they irreversibly change from a non-conductive state to a conductive state
Les moyens de connexion pourront être constitués d'un piston conducteur en relation électrique avec la première liaison, qui est sollicité par des moyens élastiques vers la seconde liaison, à l' encontre de..moyens de retenue fus blés en mesure de fondre dès que la connexion à surveiller atteint la température critiqueThe connection means may consist of a conductive piston in electrical connection with the first connection, which is urged by elastic means towards the second connection, against ... retaining means fused capable of melting as soon as the connection to be monitored reaches the critical temperature
Les moyens de connexion pourront également être constitués d'un élément isolant de type thermoretractable , dont une face, dite recto, est en contact avec la première liaison et la seconde face, dite verso, est en contact avec la seconde liaison, cet élément étant tel que, lorsque la température de la connexion a surveiller atteint la température critique, il se rétracte démasquant ainsi une surface de contact de la première liaison avec la secondeThe connection means may also consist of an insulating element of heat-shrinkable type, one face of which, called the front, is in contact with the first connection and the second face, called the back, is in contact with the second connection, this element being such that, when the temperature of the connection to be monitored reaches the critical temperature, it retracts thus exposing a contact surface of the first connection with the second
Dans une variante de ce mode de mise en oeuvre de l'invention le dispositif de surveillance thermique comporte un palpeur élastique et conducteur qui est relie électriquement a un second élément de liaison et dont une 01/48774In a variant of this embodiment of the invention, the thermal monitoring device comprises an elastic and conductive feeler which is electrically connected to a second connecting element and one of which 01/48774
extrémité libre vient en contact avec le verso de l'élément isolant thermorétractable dans la surface de contact susceptible d'être démasquée.free end comes into contact with the back of the heat-shrinkable insulating element in the contact surface capable of being unmasked.
Le dispositif de surveillance thermique peut être disposé en parallèle aux bornes de la connexion à surveiller mais également être totalement intégré à celle-ci Dans un tel mode de mise en oeuvre le premier élément de liaison sera constitué par un constituant mécanique de la connexionThe thermal monitoring device can be arranged in parallel with the terminals of the connection to be monitored, but also be completely integrated into it. In such an embodiment, the first connecting element will be constituted by a mechanical component of the connection.
On décrira ci-après, à titre d'exemples non limitatifs. diverses formes d' exécution de la présente invention en référence au dessin annexé sur lequel :There will be described below, by way of nonlimiting examples. various embodiments of the present invention with reference to the accompanying drawing in which:
La figure 1 est une vue en coupe longitudinale et transversale d'un premier mode de mise en oeuvre d'un dispositif de surveillance thermique suivant l' invention La figure 2 est une vue en coupe longitudinale et transversale d'un second mode de mise en oeuvre d'un dispositif de surveillance thermique suivant l'inventionFigure 1 is a longitudinal and cross sectional view of a first embodiment of a thermal monitoring device according to the invention Figure 2 is a longitudinal and cross sectional view of a second embodiment work of a thermal monitoring device according to the invention
La figure 3 est une vue en coupe longitudinale et transversale d'un troisième mode de mise en oeuvre d'un dispositif de surveillance thermique suivant l'invention qui est intégré à la connexion à surveillerFIG. 3 is a view in longitudinal and transverse section of a third embodiment of a thermal monitoring device according to the invention which is integrated into the connection to be monitored
La figure 4 est une vue en coupe transversale d'un quatrième mode de mise en oeuvre d'un dispositif de surveillance thermique suivant l'invention qui est intégre aux connexions à vérifier d'une prise de courantFigure 4 is a cross-sectional view of a fourth embodiment of a thermal monitoring device according to the invention which is integrated into the connections to be checked from a power outlet
Le dispositif de surveillance thermique représenté Sur la figure 1 est constitué d'un boîtier 1 réalisé en une matière isolante telle que par exemple une matière plastique, qui est percé à une première extrémité d'un logement cylindrique 3 qui se prolonge vers l'autre extrémité par un logement cylindrique 5 de même axe et de plus grand diamètre. La seconde extrémité du boîtier 1 comporte un bossage radial 7 percé d'un orifice radial 9. Le logement 3 permet de recevoir un fil électrique 11 dont le conducteur 12 est relié thermiquement et électriquement avec une connexion à contrôler située à proximité immédiate et non représentée sur le dessin. La gaine 13 du fil électrique 11 est supprimée sur une certaine longueur afin de dégager 'le conducteur 12, qui reçoit une cosse métallique 14 qui est fixée sur lui par sertissage. Cette cosse se termine par une extrémité 15 pliée transversalement. L'extrémité 15 est percée d'un orifice axial 17 qui reçoit une tige 19 d'un piston 21, ce piston étant pourvu d'une tête 23 de p-lus grand diamètre et d'une partie intermédiaire 25.The thermal monitoring device shown in Figure 1 consists of a housing 1 made of an insulating material such as for example a plastic material, which is pierced at a first end of a cylindrical housing 3 which is extended towards the other end by a cylindrical housing 5 of the same axis and of larger diameter. The second end of the housing 1 has a radial boss 7 pierced with a radial orifice 9. The housing 3 makes it possible to receive an electric wire 11 whose conductor 12 is thermally and electrically connected with a connection to be controlled located in the immediate vicinity and not shown on the drawing. The sheath 13 of the electric wire 11 is removed over a certain length in order to release the conductor 12, which receives a metal lug 14 which is fixed to it by crimping. This terminal ends with an end 15 folded transversely. The end 15 is pierced with an axial orifice 17 which receives a rod 19 of a piston 21, this piston being provided with a head 23 of larger diameter and with an intermediate part 25.
La partie 25 est entourée d'un ressort de compress.ion hélicoïdal 27 qui, d'une part est en appui sur la partie extrême 15 de la cosse 3 et, d'autre part, sur la tête 23 du piston 21, de sorte qu'il exerce sur la tête de ce piston un effort suivant la direction de la flèche F. L'extrémité libre de la tige 19 du piston 21 est creusée d'une rainure circulaire 29 dans laquelle est déposée un jonc de matière fusible 31. Cette matière fusible 31 assure le maintien du piston 21 en position à 1 'encontre de l'effort de compression exercé sur la tête 23 de celui-ci par le ressort 27, de sorte que, dès suppression de l'effort de maintien assuré par le jonc 31 le piston 21 est expulsé en direction de la flèche F. La matière fusible constituant le jonc 31 est telle qu'a une température donnée, dénommée température critique, la sollicitation exercée par le ressort 27 sur la tête de piston 23 est supérieure a 1 'effort de maintien exercé par le ]onc fusible 31 de sorte que le piston est libéréPart 25 is surrounded by a helical compression spring 27 which, on the one hand, is supported on the end part 15 of the terminal 3 and, on the other hand, on the head 23 of the piston 21, so that it exerts on the head of this piston a force in the direction of the arrow F. The free end of the rod 19 of the piston 21 is hollowed out with a circular groove 29 in which a rod of fusible material 31 is deposited. This fusible material 31 maintains the piston 21 in position against the compression force exerted on the head 23 thereof by the spring 27, so that, as soon as the holding force provided by the rod 31 the piston 21 is expelled in the direction of the arrow F. The fusible material constituting the rod 31 is such that at a given temperature, called the critical temperature, the stress exerted by the spring 27 on the piston head 23 is greater than the holding force exerted by the fuse link so that the piston is released
La seconde extrémité du boîtier 1 reçoit une pièce métallique 35 de forme cylindrique qui comporte un logement axial 37 recevant un conducteur électrique 39 qui est relié à la mise à la terre de l'installation. L'élément 35 est percé d'un trou fileté recevant une vis de serrage 36 qu_. prend place dans l' évidement 9 du bossage 7, et qui assure la connexion de la pièce 35 avec le conducteur 39The second end of the housing 1 receives a metal part 35 of cylindrical shape which comprises an axial housing 37 receiving an electrical conductor 39 which is connected to the installation earthing. The element 35 is pierced with a threaded hole receiving a clamping screw 36 qu_. takes place in the recess 9 of the boss 7, and which ensures the connection of the part 35 with the conductor 39
Le maintien en position de la pièce 35 est assuré d'une part par un encastrement 41 à sa partie supérieure dans un évidement correspondant prévu dans le boîtier 1 et par des bossages élastiques 43 prévus en extrémité de celui-ciMaintaining the position of the part 35 is provided on the one hand by a recess 41 at its upper part in a corresponding recess provided in the housing 1 and by elastic bosses 43 provided at the end thereof.
Dans ces conditions le fonctionnement du dispositif de surveillance thermique s'établit ainsi que décrit ci-apres Lorsque la connexion, non représentée sur le dessin, a laquelle est relié le conducteur électrique 12 s'échauffe la chaleur ainsi produite est transmise par le conducteur et la cosse 13 au jonc thermofusible 31 Tant que la température à laquelle est soumise le jonc 31 se trouve en dessous de la température critique , par construction, le jonc 31 assure le maintien du piston 21 à l' encontre de la sollicitation du ressort 27 Dès que cette température augmente et atteint la température critique, le jonc fusible 31 n'assure plus sa fonction de maintien, et le ressort 27 repousse le piston 21 dans le sens de la flèche F pour venir 01/48774Under these conditions, the operation of the thermal monitoring device is established as described below. When the connection, not shown in the drawing, to which the electrical conductor 12 is connected, the heat thus produced is transmitted by the conductor and the terminal 13 to the hot-melt rod 31 As long as the temperature to which the rod 31 is subjected is below the critical temperature, by construction, the rod 31 ensures the maintenance of the piston 21 against spring stress 27 From as this temperature increases and reaches the critical temperature, the fusible ring 31 no longer ensures its holding function, and the spring 27 pushes the piston 21 in the direction of the arrow F to come 01/48774
en contact avec l'élément 35 Dans ces conditions on assure une liaison électrique entre la connexion et la mise a la terre du circuit de la connexion concernée provoquant ainsi la coupure du courant en amont par le déclenchement du dispositif différentielin contact with the element 35 In these conditions an electrical connection is ensured between the connection and the earthing of the circuit of the connection concerned, thus causing the current to be cut upstream by the tripping of the differential device.
Tant que l'utilisateur n'aura pas fait le nécessaire pour remédier au problème lié à sa connexion il ne pourra rétablir le courant dans la partie de son installâtJ on protégée par le dispositif différentiel concerné La présente mventio'n permet ainsi de prévenir et signaler à l'utilisateur toute élévation de température anormale dans les connexions de son installation qui sont pourvues du dispositif de surveillance thermique suivant 1 ' invention Dans le mode de mise en oeuvre représenté sur la figure 2, le boîtier 44 est constitué d'un matériau non conducteur et comporte une partie cylindrique antérieure 45 et une partie postérieure formant bossage 46 Comme précédemment, la partie 45 comporte un logement cylindrique axial 3 qui reçoit une extrémité d'un fil électrique 11 dont le conducteur 12 est relié à une connexion électrique non représentée sur le dessin et située à proximité au dispositif L'extrémité du fil électrique 11 est pourvue d'une cosse 47 qui est sertie sur 1 extrémité du conducteur 12 du fil 11 La cosse 47 comporte une extrémité antérieure et supérieure qui s'étend vers 1 intérieur du logement 3 et vient en butée contre une protubérance interne 49 du boîtier 44 La cosse 47 est bloquée sur sa partie arrière par des butées élastiques 51 La face interne de la cosse 47 est 01/48774As long as the user has not done what is necessary to remedy the problem linked to his connection, he cannot restore the current in the part of his installation protected by the differential device concerned. This mventio'n thus makes it possible to prevent and report to the user any abnormal temperature rise in the connections of his installation which are provided with the thermal monitoring device according to the invention In the embodiment shown in FIG. 2, the box 44 is made of a non-material conductor and comprises a front cylindrical part 45 and a rear part forming boss 46 As previously, part 45 comprises an axial cylindrical housing 3 which receives one end of an electric wire 11 whose conductor 12 is connected to an electric connection not shown on the drawing and located close to the device The end of the electric wire 11 is provided with a terminal 47 which is crimped on 1 end of the conductor 12 of the wire 11 The terminal 47 has a front and upper end which extends towards 1 inside of the housing 3 and abuts against an internal protuberance 49 of the housing 44 The terminal 47 is blocked on its rear part by elastic stops 51 The internal face of the terminal 47 is 01/48774

Comme dans le mode de mise en oeuvre précédent, ia connexion entre la pièce 55 et le conducteur 59 est assurée par une vis de serrage 61 La partie antérieure et inférieure de l'élément 55 est creusée d'une cavité 63 qui reçoit un élément métallique élastique 65 qui est incurvé radialement en direction de la cosse 47, de façon que son extrémité libre vienne en contact. avec la face externe de la feuille thermorétractable 48.As in the previous embodiment, the connection between the part 55 and the conductor 59 is ensured by a clamping screw 61 The front and bottom part of the element 55 is hollowed out with a cavity 63 which receives a metallic element elastic 65 which is curved radially in the direction of the terminal 47, so that its free end comes into contact. with the outer face of the heat-shrinkable sheet 48.
Dans ces conditions le fonctionnement du présent dispositif de surveillance thermique s'établit ainsi que décrit ci-après En fonctionnement normal, c'est-a-dire lorsque la connexion a surveiller, non représentée sur le dessin, est en bon état, et donc ne s'écnauffe pas la feuille thermorétractable 48, en raison de ses qualités d'isolation, empêche le contact de l'élément 65 avec la cosse 47 Lorsqu'un échauffement de la connexion a surveiller se pioduit, la chaleur produite se transmet par le conducteur 12 à la cosse 47 et de celle-ci a la feuille thermorétractable 48 qui, lorsque la température d ' échauffement atteint la température critique, se rétracte suffisamment pour que l'extrémité libre de l'élément (.5 01/48774Under these conditions the operation of this thermal monitoring device is established as described below In normal operation, that is to say when the connection to be monitored, not shown in the drawing, is in good condition, and therefore the heat-shrinkable sheet 48 does not become entangled, due to its insulating qualities, prevents contact of the element 65 with the terminal 47 When heating of the connection to be monitored is produced, the heat produced is transmitted by the conductor 12 to the terminal 47 and the latter has the heat-shrinkable sheet 48 which, when the heating temperature reaches the critical temperature, retracts sufficiently so that the free end of the element (.5 01/48774
vienne en contact avec la cosse 47 Dans ces conditions ]a connexion se trouve reliée a la mise à la terre provoquant la coupure du courant en amont par le déclenchement du disjoncteur difrérentiel On pourrait bien entendu prévoir tout autre dispositif intermédiaire entre la connexion et le fil conducteur en relation avec la terre susceptible de se déclencher lorsque la liaison atteint la température critiquecomes into contact with the terminal 47 Under these conditions ] a connection is connected to the ground causing the current to be cut upstream by the tripping of the difrential circuit breaker We could of course provide any other intermediate device between the connection and the wire conductor in relation to earth likely to trip when the link reaches the critical temperature
On pourrait suivant l'invention réaliser un dispositif de surveillance thermique .qui soit intégré à la connexion elle-même On a représenté un tel dispositif sur la figure 80 qui comporte à sa base une cavité parallélépipédique δl dans laquelle est encastré à maintien élastique un domino métallique 82 de forme complémentaire qui est percé d'un logement axial 84 destiné à._ recevoir deux éléments conducteurs 11, 11' à raccorder qui sont maintenus en bon contact avec le domino 82 à l'aide de vis de serrage 83 Le corps 80 comporte une cavité supérieure dans laquelle est logée une cosse métallique cylindrique 85 perc e d un logement axial 86 destiné à recevoir un conducteur 29 J qui est maintenu par une vis 83J ce conducteur étant relié à la mise a la terre de l'installation On a disposé, a la base de la cosse 85, une lame ressort métallique 88 qui est en contact par son extrémité libre avec la face supérieure du domino 82 Comme précédemment, la face supérieure de ce dernier est recouverte d'une teuille 90 thermorétractable qui, en fonctionnement normal de la connexion, assure une isolation électrique entre le domino 82 et la lame ressort 88 La force élastique de cette lame ressort peut être améliorée par LE contact d'une butée 94 prévue dans le corps 80 qui vient exercer une pression sur ce ressort Dans ces conditions, comme précédemment, lorsqu un échauffement des connexions du domino 82 provoque un échauf ement, le film thermorétractable 90 se contracte laissant ainsi un libre contact au ressort a lame 88 avec la face supérieure du domino 82, entraînant ainsi le déclenchement du dispositif différentiel ainsi que décrit précédemmentAccording to the invention, a thermal monitoring device could be produced. Which is integrated into the connection itself. Such a device has been shown in FIG. 80 which comprises at its base a parallelepipedic cavity δl in which a domino is embedded with elastic support. metal 82 of complementary shape which is pierced with an axial housing 84 intended for . _ receive two conductive elements 11, 11 'to be connected which are kept in good contact with the domino 82 using clamping screws 83 The body 80 has an upper cavity in which is housed a cylindrical metal lug 85 perc ed housing axial 86 intended to receive a conductor 29 J which is held by a screw 83 J this conductor being connected to the earthing of the installation A metal spring leaf 88 is placed at the base of the terminal 85 which is in contact by its free end with the upper face of the domino 82 As previously, the upper face of the latter is covered with a heat-shrinkable sheet 90 which, in normal operation of the connection, provides electrical insulation between the domino 82 and the blade spring 88 The elastic force of this leaf spring can be improved by LE contact with a stop 94 provided in the body 80 which exerts pressure on this spring Under these conditions, as before, when heating of the domino 82 connections causes heating, the heat-shrinkable film 90 contracts thus leaving free contact with the leaf spring 88 with the upper face of the domino 82, thereby triggering the differential device as described above
On a représenté sur la figure 4 une variante de mise en oeuvre de l'invention dans laquelle le dispositif de surveillance thermique est intégré à une prise de courantFIG. 4 shows an alternative embodiment of the invention in which the thermal monitoring device is integrated into an electrical outlet
On a représenté de façon schématique sur cette figure, en traits doublement hachurés, les broches 60 et 62 solidaires d'une fiche destinée à prendre place dans une prise de courant et, en traits hachurés simples, une borne 64 d'une prise de courant qui est reliée à la mise à la terre Bien que le αispositif de surveillance thermique suivant l'invention puisse être dispose sur chacune des broches 60 et 62 il n'a été représenté sur la figure 4 qu'en relation avec la brocne 60 Cette prise comporte également des éléments métalliques élastiques 66 destinés a assurer un bon contact électrique avec la broche 60 et ces éléments métalliques élastiques sont généralement sertis ou rives sur une pièce 67 munie d'un évidemment permettant de recevoir le conducteur 71 et d'une vis αe serrage 69 qui assure le maintien de la connexion du fil 71There is shown schematically in this figure, in double hatched lines, the pins 60 and 62 secured to a plug intended to take place in a socket and, in simple hatched lines, a terminal 64 of a socket which is connected to grounding Although the thermal monitoring device according to the invention can be placed on each of pins 60 and 62, it has only been shown in FIG. 4 in relation to the pin 60 This socket also comprises elastic metallic elements 66 intended to ensure good electrical contact with the pin 60 and these elastic metallic elements are generally crimped or strands on a part 67 provided with a recess for receiving the conductor 71 and with a tightening screw 69 which maintains the connection of the wire 71
Le dispositif de surveillance thermique est ici intégre a la connexion lors du sertissage ou du πvetage des éléments 66 et 67, et est constitué d'un palpeur élastique 10 conducteur 70 dont sa forme et la fixation des éléments 66 le maintiennent en contact sur la borne de mise à la terre 64. Le long de ce palpeur 70, en sous face et lors de l'assemblage, a été disposé un film thermorétractable 77 ou autre, de façon qu'à température normale, il isole électriquement le palpeur 70 et la borne de mise à la terre 64. On comprend, dans ces conditions que, lorsque les connexions existant soit entre les éléments 66 et la broche 60, soit entre le domino 67 et le conducteur 68, sont de bonne qualité, il n'y a pas d ' échauffement de ces connexions et que, dans ces conditions le film theriorétractable 72 isole la borne de mise à la terre des éléments 66 sont de bonne qualité, il n'y a pas d ' échauffement de ces connexions et que, dans ces conditions, le fil thermorétractable 72 isole la broche 64 des éléments 66. Lorsque l'une des connexions mentionnées vient à s'échauffer, la chaleur est transmise via les rivets conducteurs 68 au palpeur 70, si bien que dans ces conditions le film thermorétractable se contracte provoquant ainsi le contact électrique du palpeur 70 avec la broche de mise à la terre 64. Dans ces conditions, comme mentionné précédemment, le dispositif différentiel est active assurant ainsi la coupure du courant et la sécurité de l'installation. The thermal monitoring device is here integrated into the connection during crimping or cleaning of the elements 66 and 67, and consists of an elastic feeler 10 conductor 70 whose shape and the attachment of the elements 66 keep it in contact on the grounding terminal 64. Along this probe 70, on the underside and during assembly, a heat-shrinkable film 77 has been placed or other, so that at normal temperature, it electrically isolates the probe 70 and the grounding terminal 64. It is understood, under these conditions that, when the connections existing is between the elements 66 and the pin 60, either between the domino 67 and the conductor 68, are of good quality, there is no heating of these connections and that, under these conditions the shrink film 72 insulates the grounding terminal from the elements 66 are of good quality, there is no heating of these connections and that, under these conditions, the heat-shrinkable wire 72 isolates the pin 64 from the elements 66. When one of the connections mentioned comes to heat, the heat is transmitted via conductive rivets 68 at p alpeur 70, so that under these conditions the heat-shrinkable film contracts causing electrical contact of the probe 70 with the grounding pin 64. Under these conditions, as mentioned previously, the differential device is active thus ensuring the cutting of the current and installation security.
