Description
Tableau pour four électrique à résistance. L'objet de la présente invention est un tableau pour four électrique à résistance, qui comporte un bâti métallique à l'intérieur du quel est monté un transformateur à plusieurs branchements au moyen desquels on peut faire varier la tension aux bornes du four. On em ploiera de préférence un autotransformateur dont les branchements aboutiront à des jacks dans lesquels s'introduit une fiche connecté- <B>CI</B> . l'un des pôles du four.
Il est montré au dessin ci-annexé, une forme d'exécution d'un four selon l'invention, donné à titre d'exemple.
La, fig. 1 en est une vue de côté, montrant une coupe par l'axe du premier jack; la fi-. 2 en est une coupe horizontale selon la ligne I-I de la fig. 1; la. fig. 3 est le schéma du tableau représenté aux fig. 1 et 2.
a est une carcasse métallique posée sur un fond b et recouverte par un plateau c dans lequel sont prévues les ouvertures nécessaires à l'introduction d'un ampèremètre d et d'un inter rupteur bipolaire e. Sur la face antérieure du tableau sont prévus cinq jacks f auxquels aboutissent des fils pris en dérivation sur l'en roulement d'un autotransformateur y disposé dans le fond du tableau.. Une fiche 1z termine un cordon i qui est relié à l'une des bornes portées par la lamelle k, bornes auxquelles aboutissent aussi les fil; amenant le courant et ceux allant au four.
Des fusibles l sont en outre prévus sur le devant du tableau.
On voit au schéma de la fig. 3 que le cou rant, après avoir traversé les fusibles, l'am pèremètre et l'interrupteur bipolaire, est con duit au travers de l'auto-transformateur dont un plus ou moins grand nombre de spires peu vent être utilisées comme enroulement secoii= daire pour l'alimentation du four.
Table for electric resistance oven. The object of the present invention is a panel for an electric resistance furnace, which comprises a metal frame inside which is mounted a transformer with several connections by means of which the voltage at the terminals of the furnace can be varied. We will preferably use an autotransformer whose connections will lead to jacks in which is inserted a plug connected- <B> CI </B>. one of the poles of the oven.
An embodiment of a furnace according to the invention, given by way of example, is shown in the accompanying drawing.
The, fig. 1 is a side view, showing a section through the axis of the first jack; the fi-. 2 is a horizontal section along the line I-I of FIG. 1; the. fig. 3 is the diagram of the table shown in FIGS. 1 and 2.
a is a metal frame placed on a base b and covered by a plate c in which the openings necessary for the introduction of an ammeter d and a bipolar switch e are provided. On the front face of the switchboard are provided five jacks f to which lead wires taken in tap-off on the rolling of an autotransformer placed there in the bottom of the switchboard. A 1z plug ends a cord i which is connected to one terminals carried by the strip k, terminals to which the wires also end; carrying the current and those going to the oven.
Fuses 1 are also provided on the front of the switchboard.
We see in the diagram of FIG. 3 that the current, after passing through the fuses, the am per meter and the bipolar switch, is conducted through the autotransformer, of which a greater or lesser number of turns can be used as secoii = winding to feed the oven.
