Abstract

SE TRATA DE UN DISPOSITIVO DE DISPARO DIFERENCIAL CUYO MECANISMO DE DISPARO (24) ESTA DESTINADO A INTERVENIR SOBRE EL ORGANO DE DISPARO DE UN DISPOSITIVO DE DISPARO PRINCIPAL EN CASO DE DEFECTO DIFERENCIAL. SEGUN LA INVENCION, ESTE MECANISMO DE DISPARO (24) COMPRENDE, PARA ESTA ACCION, UNA PALANCA PRINCIPAL, Y, ACOPLADA CON LA EMPUÑADURA DE MANIOBRA DEL DISPOSITIVO DE DISPARO PRINCIPAL, UNA EMPUÑADURA DE MANIOBRA (60), QUE ESTA DESTINADA A ASEGURAR SISTEMATICAMENTE, POR SI MISMA, BAJO EL ESFUERZO DE SU MUELLE DE RETORNO (63), UN REARME AUTOMATICO DE ESTA PALANCA PRINCIPAL (44) ANTES DE ALCANZAR SU PROPIA POSICION DE DISPARO. APLICACION EN PARTICULAR EN LOS DISYUNTORES.IT IS A DIFFERENTIAL TRIPPING DEVICE WHOSE TRIGGER MECHANISM (24) IS INTENDED TO INTERVENE ON THE ORGAN OF TRIPPING OF A MAIN TRIPPING DEVICE IN CASE OF DIFFERENTIAL DEFECT. ACCORDING TO THE INVENTION, THIS TRIGGER MECHANISM (24) INCLUDES, FOR THIS ACTION, A MAIN LEVER, AND, COUPLED WITH THE MAIN TRIGGER DEVICE HANDLE, A MANEUVER HANDLE (60), WHICH IS INTENDED TO ASSURE, BY ITSELF, UNDER THE EFFORT OF ITS RETURN SPRING (63), AN AUTOMATIC RESET OF THIS MAIN LEVER (44) BEFORE REACHING ITS OWN FIRING POSITION. PARTICULAR APPLICATION IN CIRCUIT BREAKERS.
