Abstract

Dispositif d'entraînement hydraulique, en particulier pour disjoncteurs haute tension, comportant au moins deux systèmes réversibles à cylindre et à piston et un dispositif d'actionnement commandant ces derniers au moyen de valves intermédiaires. Les valves intermédiaires 4 sont inversées mécaniquement par l'intermédiaire d'un arbre à cames 7 de sorte que on a la garantie d'un actionnement simultané de toutes les valves intermédiaires 4. Ces dispositifs d'entraînement hydrauliques sont prévus pour des disjoncteurs haute tension comportant au moins deux postes de coupure par pôle.Hydraulic drive device, in particular for high voltage circuit breakers, comprising at least two reversible cylinder and piston systems and an actuating device controlling the latter by means of intermediate valves. The intermediate valves 4 are mechanically reversed by means of a camshaft 7 so that one has the guarantee of simultaneous actuation of all the intermediate valves 4. These hydraulic drive devices are intended for high voltage circuit breakers. comprising at least two switching stations per pole.
