Abstract
Description
La présente invention concerne un dispositif de déclenchement thermique pour un appareil de protection électrique, ledit appareil comportant un levier de déclenchement articulé sur une platine et étant piloté par ledit dispositif de déclenchement pour provoquer en cas de défaut la rupture d'une liaison mécanique entraînant le déclenchement automatique d'un mécanisme de commande du disjoncteur, ce déclenchement entraînant l'ouverture de deux contacts respectivement fixe et mobile, ledit dispositif de déclenchement thermique comportant un bilame apte à coopérer avec un tiroir relié de manière articulée par l'une de ses extrémités, audit levier de manière à entraîner ledit tiroir dans le sens du déclenchement lors d'une déformation du bilame suite à une surcharge électrique, ledit tiroir coopérant avec une butée fixe par rapport au boîtier de l'appareil et destinée à guider en partie la trajectoire du tiroir lors de son déplacement.The present invention relates to a thermal tripping device for an electrical protection device, said apparatus comprising a trigger lever articulated on a plate and being controlled by said tripping device to cause in the event of a fault the breakage of a mechanical connection causing the automatic tripping of a control mechanism of the circuit breaker, this tripping causing the opening of two respectively fixed and movable contacts, said thermal tripping device comprising a bimetallic adapted to cooperate with a drawer connected in an articulated manner by one of its ends at said lever so as to drive said spool in the direction of release during deformation of the bimetal strip due to an electric overload, said spool cooperating with an abutment fixed with respect to the housing of the apparatus and intended to partly guide the trajectory drawer when moving.
La force de traction exercée par l'extrémité du bilame thermique sur le tiroir, est orientée dans une direction qui est normale au point d'appui du bilame sur le tiroir. Cette direction change quand le bilame se courbe sous l'effet thermique d'une surcharge électrique. Il est alors nécessaire que le changement de la direction de la force reste en dessous d'un angle maximum afin de rappeler le tiroir contre sa butée.The tensile force exerted by the end of the thermal bimetallic strip on the drawer is oriented in a direction which is normal to the point of support of the bimetallic strip on the drawer. This direction changes when bimetallic bends under the thermal effect of an electric overload. It is then necessary that the change in the direction of the force remains below a maximum angle in order to return the drawer against its stop.
Or, pour améliorer les performances de l'appareil, il peut être souhaitable d'utiliser un bilame dont la déflexion est trop importante pour permettre de maintenir la direction de la force dans la plage de variation permise.However, to improve the performance of the device, it may be desirable to use a bimetal whose deflection is too great to maintain the direction of the force in the range of variation allowed.
Cette déformation importante du bilame produit à son extrémité coopérant avec le tiroir, une pente plus importante qui s'oppose au déplacement du tiroir en direction d'une butée, ladite butée étant destinée à assurer partiellement le guidage dudit tiroir pendant son déplacement conduisant au déclenchement du mécanisme.This significant deformation of the bimetal produced at its end cooperating with the slide, a greater slope which opposes the displacement of the slide towards a stop, said stop being intended to partially ensure the guiding of said slide during its displacement leading to the triggering of the mechanism.
Il en résulte que la course de déclenchement du tiroir n'est pas répétitive de même que le temps de déclenchement pour un courant donné.As a result, the trigger stroke of the drawer is not repetitive as is the trip time for a given current.
La présente invention résout ces problèmes et propose un dispositif de déclenchement thermique pour un appareil de protection électrique dans lequel les temps de déclenchement sont répétitifs même en cas de déflexion importante du bilame afin d'améliorer les performances de l'appareil.The present invention solves these problems and proposes a thermal tripping device for an electrical protection apparatus in which the tripping times are repetitive even in case of significant bimetallic deflection in order to improve the performance of the apparatus.
A cet effet, la présente invention a pour objet un dispositif de déclenchement thermique pour un appareil de protection électrique, ledit dispositif étant caractérisé en ce que ledit bilame comporte, à son extrémité coopérant avec le tiroir, une partie formant rampe, ladite rampe étant agencée de manière à positionner le tiroir contre la butée précitée pendant la première phase de déformation du bilame, de manière que ladite butée assure ensuite le guidage du dit tiroir pendant son déplacement.For this purpose, the subject of the present invention is a thermal tripping device for an electrical protection device, said device being characterized in that said bimetal strip comprises, at its end cooperating with the drawer, a ramp portion, said ramp being arranged so as to position the slide against the aforementioned abutment during the first phase of deformation of the bimetal, so that said stop then guiding said drawer during its movement.
Selon une caractéristique particulière, le plan de la partie formant rampe forme avec la direction longitudinale du bilame un angle α d'environ 10°.According to a particular characteristic, the plane of the ramp portion forms with the longitudinal direction of the bimetal an angle α of about 10 °.
Selon une autre caractéristique, la partie formant rampe précitée est réalisée par pliage de l'extrémité du bilame.According to another feature, the aforementioned ramp portion is made by folding the end of the bimetal.
Selon une autre réalisation, la partie formant rampe précitée est réalisée par cisaillage d'une partie de l'extrémité du bilame puis pliage de cette partie de manière à former une rampe.According to another embodiment, the aforesaid ramp portion is made by shearing a portion of the end of the bimetal then folding this portion to form a ramp.
Selon une autre réalisation, ladite rampe est réalisée par l'intermédiaire d'une pièce rapportée fixée à l'extrémité du bilame.According to another embodiment, said ramp is made via an insert attached to the end of the bimetallic strip.
Selon une réalisation particulière, l'appareil comportant une partie haute comportant le mécanisme de commande et une partie basse comportant des moyens de fixation de l'appareil à une surface de support, ladite rampe est réalisée par pliage vers le bas de l'appareil de l'extrémité du bilame, ladite extrémité étant orientée vers le haut de l'appareil, du côté du bilame opposé au tiroir.According to a particular embodiment, the apparatus comprising an upper part comprising the control mechanism and a lower part comprising means for fixing the apparatus to a support surface, said ramp is made by folding down the apparatus of the end of the bimetallic strip, said end being directed towards the top of the apparatus, on the side of the bimetall opposite the drawer.
Selon une autre réalisation, l'appareil comportant une partie haute comportant le mécanisme de commande et une partie basse comportant des moyens de fixation de l'appareil à une surface de support, ladite rampe est réalisée par pliage vers le bas de l'extrémité du bilame, celle-ci étant alors orientée vers le bas de l'appareil et s'étendant du même coté du bilame que le tiroir.According to another embodiment, the apparatus comprising an upper part comprising the control mechanism and a lower part comprising means for fixing the the apparatus to a support surface, said ramp is made by folding down the end of the bimetal, the latter then being oriented towards the bottom of the apparatus and extending on the same side of the bimetallic strip as the drawer .

On a donc réalisé grâce à l'invention un appareil de protection électrique dans lequel le tiroir est rappelé vers sa butée dés le début de la déflexion du bilame. Ainsi, le tiroir est correctement positionné, avant que le bilame ne commence son déplacement dans le sens du déclenchement. Ainsi, le positionnement du tiroir sur sa butée permet à ladite butée de guider en partie le tiroir lors de son déplacement. La trajectoire et la course de déclenchement du tiroir sont donc répétitives ainsi que les temps de déclenchement pour un courant donné, d'où une amélioration des performances de l'appareil. Cette amélioration présente l'avantage de représenter un coût industriel faible, n'occupera pas la place d'un autre composant du disjoncteur, et n'induira pas de modification profonde de la chaîne cinématique du disjoncteur.Therefore, thanks to the invention, an electrical protection device has been realized in which the drawer is biased towards its stop from the beginning of the deflection of the bimetallic strip. Thus, the drawer is correctly positioned, before the bimetallic begins to move in the direction of tripping. Thus, the positioning of the slide on its stop allows said stop to partially guide the slide during its movement. The trajectory and the trigger stroke of the drawer are therefore repetitive as well as the tripping times for a given current, hence improving the performance of the device. This improvement has the advantage of representing a low industrial cost, will not occupy the place of another component of the circuit breaker, and will not induce a profound change in the kinematic chain of the circuit breaker.

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.Of course, the invention is not limited to the embodiments described and illustrated which have been given by way of example.
C'est ainsi que d'autres moyens pourraient être envisagés pour créer une rampe.This is how other ways could be considered to create a ramp.
Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont réalisées suivant son esprit.On the contrary, the invention comprises all the technical equivalents of the means described and their combinations if they are carried out according to its spirit.
