Abstract

DISPOSITIVO DISPARADOR PARA UNINTERRUPTOR DE PROTECCION CONTRA INTENSIDAD DE AVERIA. CONSTA DE UNA CULATA DE IMAN (10) EN FORMA DE "U", CON UN NERVIO DE CULATA (12) Y DOS BRAZOS (14, 16). EN EL NERVIO DE CULATA SE DISPONE UN IMAN PERMANENTE (32), CUYO CAMPO MAGNETICO SE CIERRA POR EL AIRE. EN CADA UNO DE LOS BRAZOS DE LA CULATA SE DISPONE UN BOBINADO (18, 20) Y EN LOS EXTREMOS LIBRES (22 Y 24) DE LOS BRAZOS SE ALOJA UN INDUCIDO (26) CON UNA ESPIGA (28) QUE ABRE O CIERRA LOS CONTACTOS DEL INTERRUPTOR. DEBIDO A LA INTENSIDAD DE AVERIA, EL CAMPO MAGNETICO SE INTENSIFICA EN UNO DE LOS BRAZOS Y SE ANULA EN EL OTRO, CON LO QUE SE ABREN LOS CONTACTOS DEL INTERRUPTOR POR EFECTO DE UN MUELLE (30). EXISTEN DIFERENTES ALTERNATIVAS CONSTRUCTIVAS.
