Abstract

a. Interrupteur électrique perfectionné. b. Interrupteur électrique comportant un réservoir réfrigéré installé à une certaine distance, qui contient un liquide diélectrique et qui assure le remplissage d'un cylindre situé à proximité immédiate d'une buse isolante, l'une des extrémités de ce cylindre étant commandée par un piston, tandis que son autre extrémité est fermée par le contact mobile de l'interrupteur. c. S'applique à l'extinction des arcs de coupure incorporés dans des circuits parcourus par des courants électriques intenses.at. Advanced electrical switch. b. Electrical switch comprising a refrigerated tank installed at a certain distance, which contains a dielectric liquid and which ensures the filling of a cylinder located in the immediate vicinity of an insulating nozzle, one of the ends of this cylinder being controlled by a piston, while its other end is closed by the movable contact of the switch. vs. Applies to the extinction of breaking arcs incorporated in circuits traversed by intense electric currents.
