Abstract

a. Ensemble collecteur de courant à balais massifs avec un moyen enfermant le collecteur de courant et les balais dans une cavité essentiellement étanche au fluide par rapport à l'atmosphère extérieure, un moyen pour mettre en circulation un gaz sous pression à travers la cavité. b. Ensemble caractérisé en ce que le gaz contient un additif qui est un produit organique à l'état de vapeur permettant une chute de tension sur les balais qui ne dépasse pas 0,2 volt et une usure des balais ne soit pas supérieure à 20 millimètres cubes/Mn de course sur la bague de glissement, en travaillant à une température légèrement inférieure à la température critique de la masse du balai.at. A solid brush current collector assembly with means enclosing the current collector and the brushes in a cavity substantially fluid-tight to the outside atmosphere, means for circulating a pressurized gas through the cavity. b. Assembly characterized in that the gas contains an additive which is an organic product in the vapor state allowing a drop in voltage on the brushes which does not exceed 0.2 volts and a wear of the brushes is not greater than 20 cubic millimeters / Mn of travel on the sliding ring, working at a temperature slightly below the critical temperature of the brush mass.
