Abstract

EL PRESENTE INVENTO SE REFIERE A UN INTERRUPTOR DIFERENCIAL TETRAPOLAR QUE COMPRENDE UN CAPTADOR DIFERENCIAL DISPUESTO PARA DETECTAR UNA CORRIENTE DE FUGA, UN DISPOSITIVO DE CONTROL CONECTADO AL CAPTADOR Y UN MECANISMO DE DESCONEXION DE LOS CONTACTOS DEL INTERRUPTOR. EL MECANISMO DE DESCONEXION COMPRENDE UNA BARRA DE CONMUTACION (16) QUE LLEVA CONTACTOS MOVILES (15A, 15B, 15C, 15D). ESTA ADEMAS EQUIPADO DE DOS ENSANCHES (18, 19) QUE ACTUAN COMO LEVAS EN LOS CONTACTOS MOVILES (15A, 15D) DE TAL MANERA QUE LA DISTANCIA ENTRE ESTOS CONTACTOS CON RESPECTO A LOS CONTACTOS FIJOS (14A, 14D) CORRESPONDIENTES ES INFERIOR A LA DE LOS CONTACTOS MOVILES (15B, 15C) CON RESPECTO A SUS CONTACTOS FIJOS (14B, 14C). POR ELLO, LAS SECUENCIAS DE CIERRE AUTORIZADAS SIGUIENTES DE LOS CONTACTOS EN CASO DE DETECCION DE FUGA SON RESPECTIVAMENTE NEUTRO NEUTROTHE PRESENT INVENTION REFERS TO A TETRAPOLAR DIFFERENTIAL SWITCH WHICH INCLUDES A DIFFERENTIAL SENSOR INTENDED TO DETECT A LEAKAGE CURRENT, A CONTROL DEVICE CONNECTED TO THE SENSOR AND A DISCONNECTION MECHANISM FOR THE SWITCH CONTACTS. THE DISCONNECTION MECHANISM INCLUDES A SWITCHING BAR (16) THAT CARRIES MOBILE CONTACTS (15A, 15B, 15C, 15D). IT IS FURTHER EQUIPPED WITH TWO EXTENSIONS (18, 19) THAT ACT AS CAMS IN THE MOBILE CONTACTS (15A, 15D) IN SUCH A WAY THAT THE DISTANCE BETWEEN THESE CONTACTS WITH RESPECT TO THE FIXED CONTACTS (14A, 14D) IS LESS THAN THE THE MOBILE CONTACTS (15B, 15C) REGARDING THEIR FIXED CONTACTS (14B, 14C). THEREFORE, THE FOLLOWING AUTHORIZED CLOSING SEQUENCES OF CONTACTS IN CASE OF LEAK DETECTION ARE RESPECTIVELY NEUTRAL NEUTRAL
