Abstract

EN DISYUNTORES E INTERRUPTORES DE PROTECCION CONFIGURADOS EN EJECUCION MODULAR, LAS PIEZAS ACCESORIAS DEBEN SER TAMBIEN LO MAS COMPACTAS POSIBLES Y AHORRAR EL MAXIMO DE ESPACIO, CON EL FIN DE LIMITAR LAS DIMENSIONES DE LAS CAJAS DE INTERRUPTOR Y GARANTIZAR TAMBIEN EL ACCESO A LOS COMPONENTES AFECTADOS. EN UNA UNIDAD DE ACTIVACION (1) PARA DISYUNTOR E INTERRUPTOR DE PROTECCION, EJECUTADA ESPECIALMENTE COMO DISPARADOR DE SUBTENSION, SE CONSIGUE ESTE OBJETIVO DE MANERA QUE UNA CLAVIJA DE CONEXION O TENSION (12) QUE SOBRESALE HACIA UN LADO DEL MECANISMO DE CIERRE (8) DEL INTERRUPTOR, ACTUA SOBRE LA PALANCA TENSORA (9) DE LA UNIDAD DE ACTIVACION (1), QUE ESTA CONFIGURADA COMO PALANCA DE UN SOLO BRAZO Y QUE GIRA EN TORNO A UN EJE DE GIRO (14) DISPUESTO EN LA CARCASA (13) DE LA UNIDAD DE ACTIVACION (1), PERPENDICULARMENTE AL EMPUJADOR DE DISPARO (7), Y QUE ACTUA CON POR LO MENOS UN PUNTO DE PRESION (15) SITUADO ENTRE SU EXTREMO LIBRE DE PALANCA Y EL EJE DE GIRO (14), SOBRE EL PRIMER BRAZO DE PALANCA (16) DE LA PALANCA DE DISPARO (10) CONFIGURADA COMO BALANCIN DE DOS BRAZOS, QUE POR EL EXTREMO DE LA CARCASA (13) SITUADO JUNTO A LA CABEZA (17) DEL EMPUJADOR DE DISPARO (7) ESTA ALOJADA DE TAL MODO QUE PUEDE GIRAR EN TORNO A UN EJE DE GIRO (18) PARALELO AL EJE DE GIRO (14) DE LA PALANCA TENSORA (9), QUE AL RECIBIR LA IMPULSION DE LA PALANCA TENSORA (9) PRESIONA CON SU SEGUNDO BRAZO DE PALANCA (19) EL EMPUJADOR DE DISPARO (7) CARGADO POR LA FUERZA DE UN MUELLE CONTRA LA BOBINA DE DISPARO (5), Y QUE EN ESTE SEGUNDO BRAZO DE PALANCA (19) ESTA DIRIGIDO CONTRA EL MECANISMO DE CIERRE (8) UN BRAZO DISPARADOR (20), QUE SI NO ES SUFICIENTE LA TENSION, ACCIONA AL TRINQUETE DE DISPARO (11) EN EL CIERRE DE CONEXION, DE MODO QUE EL INTERRUPTOR PERMANECE SIN TOCAR CONTACTO Y NO PUEDE SER CONECTADO.IN PROTECTED CIRCUIT BREAKERS AND SWITCHES CONFIGURED IN MODULAR EXECUTION, THE ACCESSORY PARTS MUST ALSO BE AS COMPACT AS POSSIBLE AND SAVE THE MAXIMUM OF SPACE, IN ORDER TO LIMIT THE DIMENSIONS OF THE COMPARTMENT BOXES AND TO GUARANTEE THEM. IN AN ACTIVATION UNIT (1) FOR A PROTECTION CIRCUIT BREAKER AND SWITCH, EXECUTED ESPECIALLY AS A SUB-VOLTAGE TRIGGER, THIS OBJECTIVE IS ACHIEVED SO THAT A CONNECTION PIN OR TENSION (12) PROJECTS TOWARDS ONE SIDE OF THE CLOSING MECHANISM (8) OF THE SWITCH, ACTING ON THE TENSIONING LEVER (9) OF THE ACTIVATION UNIT (1), WHICH IS CONFIGURED AS A SINGLE ARM LEVER AND THAT TURNS AROUND A TURN AXLE (14) ARRANGED IN THE HOUSING (13) OF THE ACTIVATION UNIT (1), PERPENDICULARLY TO THE TRIGGER PUSHER (7), AND THAT OPERATES WITH AT LEAST ONE PRESSURE POINT (15) LOCATED BETWEEN ITS FREE END OF LEVER AND THE AXLE OF TURN (14), ABOVE THE FIRST LEVER ARM (16) OF THE TRIGGER LEVER (10) CONFIGURED AS A TWO-ARM ROCKER, WHICH AT THE END OF THE HOUSING (13) LOCATED NEXT TO THE HEAD (17) OF THE TRIGGER PUSHER (7) IS LODGED SUCH MODE THAT CAN TURN AROUND A TURN AXIS (18) PARALLEL TO A TURN AXLE (14) OF THE TENSIONING LEVER (9), WHEN RECEIVING THE IMPULSION OF THE TENSIONING LEVER (9) PRESSES WITH ITS SECOND LEVER ARM (19) THE TRIGGER PUSHER (7) LOADED BY THE FORCE OF A SPRING AGAINST THE TRIGGER COIL (5), AND THAT IN THIS SECOND LEVER ARM (19) IT IS DIRECTED AGAINST THE CLOSING MECHANISM (8) A TRIGGER ARM (20), WHICH IF THE TENSION IS NOT ENOUGH, IT ACTUATES THE TRIP RATCHET (11) AT THE CONNECTION CLOSURE, SO THE SWITCH REMAINS WITHOUT TOUCHING CONTACT AND CANNOT BE CONNECTED.
