(54) Deionization cell for the extinction of the electric arc


(57) The present invention relates to a deionization cell for the extinction of the electric arc, particularly suitable for automatic magneto-thermal switches. In the cell itself special elements are provided for the subdivision of the arc and they are constituted by conductive bodies delimitated by a continuous convex curved surface (preferably spherical) and distributed and spaced so that the partial arcs which are generated tend to focus automatically between the nearest points of the curved facing surfaces. The mentioned spheres may be distributed within the entire space contained by the conductive fork which generates the arc expansion.
