Abstract

Συσκευή ηλεκτρικής ισχύος για κάμινο ηλεκτρικού τόξου (60) που περιλαμβάνει τουλάχιστον ένα ηλεκτρόδιο (62) και που μπορεί να συνδεθεί με ένα δίκτυο παροχής ισχύος (50) για την παροχή στο ηλεκτρόδιο (62) της ηλεκτρικής ενέργειας για τη δημιουργία ενός ηλεκτρικού τόξου για τήξη μιας μεταλλικής μάζας. Η συσκευή περιλαμβάνει μια ηλεκτρική μονάδα ρύθμισης (12) που παρεμβάλλεται και συνδέεται με το δίκτυο παροχής ισχύος (50) και το ηλεκτρόδιο (62) και είναι σχεδιασμένη να ρυθμίζει τουλάχιστον μια ηλεκτρική ποσότητα για την τροφοδοσία του ηλεκτροδίου (62). Η συσκευή περιλαμβάνει τουλάχιστον μια διάταξη ανίχνευσης (20, 22) για την ανίχνευση της ηλεκτρικής ποσότητας, που παρεμβάλλεται μεταξύ του ηλεκτροδίου (62) και της ηλεκτρικής μονάδας ρύθμισης (12), μια διάταξη τοποθέτησης (46) για τη μετακίνηση του τουλάχιστον ενός ηλεκτροδίου (62) πλησιέστερα προς/μακριά από την μεταλλική μάζα προς τήξη και μια μονάδα ελέγχου και χειρισμού (16).
