Abstract

DISYUNTOR DE CIRCUITO ELECTRICO QUE TIENE MEDIOS OPERATIVOS CON CAPACIDAD DE LIMITACION DE CORRIENTE. COMPRENDE UNA BARRA TRANSVERSAL AISLANTE (84) QUE SOPORTA PIVOTANTEMENTE UN CONTACTO (52) DE CADA PAR DE CONTACTOS Y QUE TIENE, EN CADA CONEXION PIVOTANTE (110) CON UN CONTACTO, UNA PORCION (270) QUE DEFINE UNA CAVIDAD (282) DEL CONTACTO ASOCIADO Y EN LA QUE SE COLOCAN MEDIOS DE RETENCION (286, 288) QUE COOPERAN CON DICHA PORCION TERMINAL, DE TAL MANERA QUE OBLIGAN NORMALMENTE AL CONTACTO (62) A MOVERSE JUNTAMENTE Y AL UNISONO CON LA BARRA TRANSVERSAL (84) Y PERMITEN QUE EL CONTACTO SE ABRA INDEPENDIENTEMENTE DE LA BARRA TRANSVERSAL BAJO LA ACCION DE LAS FUERZAS ELECTRODINAMICAS QUE RESULTAN DE LA CORRIENTE DE FUGA DE ALTO NIVEL QUE FLUYE POR LOS CONTACTOS.ELECTRICAL CIRCUIT BREAKER THAT HAS OPERATING MEANS WITH CURRENT LIMITING CAPACITY. IT INCLUDES AN INSULATING CROSS BAR (84) THAT PIVOTALLY SUPPORTS A CONTACT (52) OF EACH PAIR OF CONTACTS AND THAT HAS, IN EACH PIVOTING CONNECTION (110) WITH A CONTACT, A PORTION (270) THAT DEFINES A CAVITY (282) OF THE CONTACT ASSOCIATED AND IN WHICH RETENTION MEANS (286, 288) ARE PLACED THAT COOPERATE WITH SAID TERMINAL PORTION, IN SUCH A WAY THAT NORMALLY FORCES THE CONTACT (62) TO MOVE TOGETHER AND IN UNISON WITH THE TRANSVERSE BAR (84) AND ALLOW THE CONTACT IS OPENED INDEPENDENTLY OF THE CROSS BAR UNDER THE ACTION OF THE ELECTRODYNAMIC FORCES RESULTING FROM THE HIGH LEVEL LEAKAGE CURRENT FLOWING THROUGH THE CONTACTS.
