More Information
Summary:The invention relates to a novel electromagnetic actuator comprising permanent magnets and having improved tripping speed and motor torque in relation to those of the prior art. The main use of the invention is the actuation of an electro-mechanical load interrupter specifically to carry out the sectioning operations of a mechatronic circuit breaker intended to interrupt high currents at high voltage. L'invention concerne un nouvel actionneur électromagnétique à aimants permanents à vitesse de déclenchement et couple moteur améliorés par rapport à ceux selon l'état de l'art. L'application principale visée est l'actionnement d'un interrupteur-sectionneur électromécanique spécifiquement pour réaliser les manuvres de sectionnement d'un disjoncteur mécatronique destiné à couper des courants élevés sous haute tension.
