Abstract

UN PARARRAYOS (10) DESCONECTABLE COMPRENDE UN LIMITADOR DE SOBRETENSION (16), UN DISPOSITIVO DE DESCONEXION (18) DE CONTACTO (22) ACCIONADO POR UN MECANISMO (24), Y UN CIRCUITO DE DISPARO QUE COOPERA CON EL MECANISMO (24) PARA ASEGURAR LA ABERTURA DEL CONTACTO (22) CUANDO EL LIMITADOR DE SOBRETENSION ES DEFECTUOSO. LA DESCONEXION SE REALIZA DURANTE UN PRIMER ESTADO TRANSITORIO DE PUESTA EN CORTOCIRCUITO DEL LIMITADOR DE SOBRETENSION (16), ANTES DE UN SEGUNDO ESTADO FINAL DE DESTRUCCION QUE CORRESPONDE A UN CIRCUITO DE TIERRA ABIERTO. EL TIEMPO DE DESCONEXION ES INFERIOR A 20MS CUANDO LA CORRIENTE LIMITADA ALCANZA O SE ENCUENTRA POR ENCIMA DE UNA INTENSIDAD DE 10A, Y RESPECTIVAMENTE INFERIOR A 100MS Y 50MS PARA INTENSIDADES DE CORRIENTE DE 0,25A Y 1A. APLICACION: PROTECCION DE UNA INSTALACION ELECTRICA DE BAJA TENSION.
