Abstract

LA INVENCION SE REFIERE A UNA INSTALACION DE HORNO DE ARCO ELECTRICO TRIFASICO, EN PARTICULAR, PARA EL TRATAMIENTO DE ACERO, CON UNA BOBINA DE REACTANCIA CONECTADA EN SERIE ENTRE LA RED PUBLICA Y UN TRANSFORMADOR DEL HORNO, ESTANDO DISPUESTO EN PARALELO A LA MISMA UN DESCONECTADOR BYPASS. PARA PODER EVITAR REACCIONES NEGATIVAS EXCEPCIONALMENTE RAPIDAS, EN PARTICULAR, TAMBIEN REDES DEBILES, SE PROPONE QUE EL DESCONECTADOR BYPASS (20) SEA UN PUENTE DE TIRISTORES (21) TRIFASICO CONECTADO AL ELEMENTO DE CONTROL (31).
