Abstract

DISPOSITIVO DE DETECCION Y PROTECCION DE SOBREVELOCIDAD EN TURBINAS DE VAPOR. UNOS CANALES REDUNDANTES DE DETECCION DE SOBREVELOCIDAD PROPORCIONAN SEÑALES DE ACCIONAMIENTO MEDIANTE SENSORES MAGNETICOS ACOPLADOS AL EJE DEL ROTOR DE LA TURBINA, CONVERTIDORES DE FRECUENCIA Y COMPARADORES DE TENSION. LAS SEÑALES ACTIVAN UN CIRCUITO DE ELEMENTOS DE CONMUTACION, QUE LAS DESVIA A SU VEZ HACIA UNOS CIRCUITOS MONITORES A TRAVES DE CIRCUITOS EN DERIVACION. LOS CIRCUITOS MONITORES ESTAN CONSTITUIDOS POR ELEMENTOS DE DETECCION DE LA CORRIENTE DERIVADA Y ELEMENTOS DE RESPUESTA. LOS ELEMENTOS DE DETECCION SON RESISTENCIAS Y TRANSISTORES.
