Abstract

PARA EVITAR OSCILACIONES INADMISIBLES DE ELECTRODOS EN UN CIRCUITO REGULADOR PARA EL REGLAJE DE LA IMPERANCIA DE UN HORNO DE ARCO VOLTAICO (1) CON, AL MENOS, UN ELECTRODO (2), UN ELEVADOR HIDRAULICO (5) PARA EL ELECTRODO (2) Y CON UN REGULADOR (10) CONTROLANDO EL ELEVADOR (5), REGULADOR AL QUE SE LE AÑADE EN EL LADO DE ENTRADA UN TRANSMISOR DE VALOR REAL (13) PARA LA IMPEDANCIA Y UNA ENTRADA (15) PARA EL VALOR TEORICO DE LA IMPEDANCIA, SE PROPONE UNA FASE DE CORRECCION (16) PARA EL FORTALECIMIENTO DEL REGULADOR QUE ES ACCIONABLE POR UN TRANSMISOR (17) PARA EL FORTALECIMIENTO DEL TRAMO DE REGULACION CON LA IDEA DE UN CAMBIO EN SENTIDO OPUESTO AL FORTALECIMIENTO DEL REGULADOR PARA UNA VARIACION DEL FORTALECIMIENTO DEL TRAMO.
