Abstract

SE TRATA DE UN DISPOSITIVO DE DISPARO DIFERENCIAL QUE COMPRENDE, BAJO UNA TAPA (20) POR LA CUAL ESTA PEGADA A LA CAJA (12) DE UN DISPOSITIVO DE DISPARO PRINCIPAL (11), UN DETECTOR DE DEFECTO (21) APTO PARA SUMINISTRAR UNA CORRIENTE DIFERENCIAL EN RESPUESTA A UN DEFECTO, UN RELE SENSIBLE (22) CONTROLADO POR EL DISPARADOR DE DEFECTO (21), Y, UN MECANISMO DE DISPARO (24) QUE BAJO EL CONTROL DEL RELE SENSIBLE (22), ES APTO PARA INTERVENIR SOBRE EL DISPOSITIVO DE DISPARO PRINCIPAL (11): SEGUN LA INVENCION, EL RELE SENSIBLE (22) Y EL MECANISMO DE DISPARO (24) SON LLEVADOS POR LA TAPA (20) MIENTRAS QUE EL DETECTOR DE DEFECTO (21), Y EN SU CASO, LA RESISTENCIA (41) DEL CIRCUITO DE PRUEBA EVENTUALMENTE PREVISTO, SON LLEVADOS POR LA CAJA (12) DEL DISPOSITIVO DE DISPARO PRINCIPAL (11). APLICACION EN LOS INTERRUPTORES O DISYUNTORES DIFERENCIALES.THIS IS A DIFFERENTIAL TRIPPING DEVICE UNDERSTANDING, UNDER A COVER (20) WHICH IS Glued TO THE BOX (12) OF A MAIN TRIPPING DEVICE (11), A DEFECTIVE DETECTOR (21) SUITABLE TO SUPPLY A CURRENT DIFFERENTIAL IN RESPONSE TO A DEFECT, A SENSITIVE RELAY (22) CONTROLLED BY THE DEFECT TRIGGER (21), AND, A TRIP MECHANISM (24) THAT UNDER THE CONTROL OF THE SENSITIVE RELAY (22), IS SUITABLE TO INTERVENE ON THE DEVICE OF MAIN TRIP (11): ACCORDING TO THE INVENTION, THE SENSITIVE RELAY (22) AND THE TRIP MECHANISM (24) ARE CARRIED BY THE COVER (20) WHILE THE DEFECT DETECTOR (21), AND IN ITS CASE, THE RESISTANCE (41) OF THE EVENTUALLY INTENDED TEST CIRCUIT, THEY ARE CARRIED BY THE CASE (12) OF THE MAIN TRIPPING DEVICE (11). APPLICATION IN THE DIFFERENTIAL SWITCHES OR CIRCUIT BREAKERS.
