Abstract

Oppfinnelsen gjelder en styreanordning for vekselstrømsreduksjonsovner 15 med elektroder 14, omfattende en transformator 11 og et reguleringssystem 1 for styrt energitilførsel til vekselstrømsreduksjonsovnene 15, hvor reguleringssystemet styrer forstillingsanordningen 17 for elektrodene 14, der styreanordningen videre omfatter styrbare kraftelektroniske vekselstrømsbrytere 13 som er sekundærsidig koblet til høystrømslederne og er forbundet med reguleringssystemet 1 over en tennledning 16 for overføring av styrende tennimpulser, og der styreanordningen er utført slik at korte svingninger i de elektriske parametrene utglattes kun av vekselstrømsbryterne 13.
