Abstract
INTERRUPTOR DE PROTECCION DE CORRIENTE DE DEFECTO. CONSTA DE UNOS CONTACTOS DE CONEXION (1) QUE SE ACCIONAN POR MEDIO DE UN CERROJO DE CONEXION (2) Y DESENGATILLAN MEDIANTE UN RELE DE DISPARO (3); DE UN TRANSFORMADOR DE CORRIENTE DE SUMA (4), CUYO NUCLEO ESTA PREMAGNETIZADO MEDIANTE LAS CORRIENTES ELECTRICAS QUE FLUYEN A TRAVES DEL CIRCUITO A VIGILAR, FORMADO POR EL CONDUCTOR DE FASE (5) Y POR EL CONDUCTOR NEUTRO (6); DE UN CIRCUITO ALIMENTADOR (87) QUE RECIBE Y TRANSFORMA LA CORRIENTE ELECTRICA QUE FLUYE DEL CIRCUITO A VIGILAR, Y DE UN CIRCUITO DE DISPARO (9) FORMADO POR UN ARROLLAMIENTO (7) ENLAZADO CON EL RELE DE DISPARO (3) Y CON EL CIRCUITO ALIMENTADOR (8). EL SISTEMA OFRECE VARIANTES DEBIDAS A DIVERSAS CONCEPCIONES DEL CIRCUITO ALIMENTADOR Y DEL CIRCUITO DE DISPARO.
