Abstract

La présente invention concerne un appareil de coupure de courant électrique comportant au moins un ensemble unipolaire de phase et un mécanisme de commande, ledit ensemble comportant une chambre de coupure logeant un contact fixe et un contact mobile (7), les différents contacts mobiles étant portés par un arbre (8), un dispositif de protection thermique comportant un bimétal dit actif (26) et un bimétal dit de compensation (27), le bilame de compensation (27) étant monté en rotation autour d’un axe fixe (29) dit premier de l’appareil et les deux bilames étant solidarisés par l’une de leurs extrémités, au moyen d’un dispositif d’accrochage (31). Cet appareil est caractérisé en ce que l’axe dit second (33) de rotation de l’arbre (8) porte-contacts mobiles et l’axe dit premier (29) de rotation du bilame de compensation (27), sont amenés à proximité l’un de l’autre et s’étendent sensiblement parallèlement l’un par rapport à l’autre, et en ce que l’arbre précité (8) comporte une pièce dite première (34) coopérant avec une pièce dite seconde (35) solidaire en rotation du bilame de compensation (27), ces deux pièces (34,35) étant agencées l’une par rapport à l’autre de telle manière qu’après un déclenchement du mécanisme, lors de l’entraînement de l’arbre (8) porte-contacts mobile dans la direction de l’ouverture des contacts, la pièce dite première (34) entraîne en rotation la pièce dite seconde (35) et donc le bilame de compensation (27) dans un sens opposé à celui ayant entraîné le déclenchement du mécanisme jusqu’à obtenir le ré-accrochage des deux bilames (26,27) l’un par rapport à l’autre.The present invention relates to an electrical power cut-off device comprising at least one unipolar phase assembly and a control mechanism, said assembly comprising a breaking chamber accommodating a fixed contact and a movable contact (7), the various mobile contacts being carried. by a shaft (8), a thermal protection device comprising a bimetal said active (26) and a bimetal said compensation (27), the bimetallic compensation (27) being rotatably mounted about a fixed axis (29) said first of the apparatus and the two bimetals being secured by one of their ends, by means of a hooking device (31). This apparatus is characterized in that the so-called second axis (33) of rotation of the movable contact-carrying shaft (8) and the so-called first axis (29) of rotation of the compensating bimetallic strip (27) are brought to bear. proximity to one another and extend substantially parallel to each other, and in that the aforementioned shaft (8) comprises a so-called first piece (34) cooperating with a so-called second piece ( 35) integral in rotation with the compensating bimetallic strip (27), these two parts (34, 35) being arranged relative to each other in such a way that after a triggering of the mechanism, during the driving of the moving contact shaft (8) in the direction of opening of the contacts, said first piece (34) rotates said second piece (35) and thus the compensating bimetallic strip (27) in a direction opposite to the one that triggered the mechanism until the two bimetallic strips were re-latched (26,27 ) relative to each other.
