Description

Lichtbogenofen mit einem ihm zugeordneten Transformator, der die Kippbewegungen des Ofens oder die Fahrbewegungen der Elektrodenhalter mitmacht Die Erfindung bezieht sich auf einen Lichtbogenofen mit einem ihm zugeordneten Transformator, der die Kippbe«#egungen des Ofens oder die Fahrbewegungen der Elektrodenhalter mitmacht. Solche Lichtbogenöfen sind bereits vorgeschlagen worden. Die Erfindung bezweckt eine weitere Vervollkommnung der Lichtbogenöfen dieser Gattung und besteht darin, daß der Transformator primärseitig über einen an ihm angebrachten federnden Schleifstromabnehmer und über eine den Bewegungen des Transformators räumlich angepaßte und fest angeordnete Schleifleitung an das Stromnetz -angeschlossen ist.Arc furnace with a transformer assigned to it, which controls the tilting movements of the furnace or the movements of the electrode holder participate. The invention relates on an electric arc furnace with a transformer assigned to it, which the Tilts the furnace or participates in the movement of the electrode holder. Such arc furnaces have been proposed. The invention aims a further improvement of the arc furnaces of this type and consists in that the primary side of the transformer has a resilient sliding current collector attached to it and one that is spatially adapted and fixed to the movements of the transformer Conductor line is connected to the power grid.

Gegenüber der. üblichen beweglichen Leitungen, die die Primärseite des Ofentransformators mit einer ortsfesten Stromzufüh: rung verbinden, wird durch die Erfindung auf der Primärseite eine wesentliche Verringerung der Verluste erzielt, die bei den üb-.71 Leitungen infolge der erforderlichen Bewegungen des Transformators und der daher erforderlichen langen Zuleitungen ganz erheblich sein können.Compared to the. usual moving lines covering the primary side of the furnace transformer with a stationary power supply is connected by the invention achieves a significant reduction in losses on the primary side, those in the over-.71 lines as a result of the necessary movements of the transformer and therefore the long supply lines required can be quite considerable.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung in einer Seitenansicht auf einen Lichtbogenofen.The drawing illustrates an embodiment of the invention in a side view of an electric arc furnace.

Der Lichtbogenofen i ist kippbar eingerichtet, wobei Elektrodenhalter 2 durch Anschlüsse 3, kurze flexible Leitungen und Anschlüsse 4. mit starren Stromschienen 5 verbunden sind, die an die Sekundärseite eines Ofentransformators 6 angeschlossen sind. Die Primärseite des Transformators ist über Anschlüsse 7 an von ortsfesten Haltern 8 getragene federnde Stromabnehmer 9 angeschlossen, die etwa so ausgebildet sein können wie die Stromabnehmer elektrischer Fahrzeuge. Die Stromabnehmer 9 schleifen auf Stromzuführungen io, die isoliert von einem ortsfesten Gerüst i i getragen und durch entsprechende Anschlüsse 12 an das -Netz 13 angeschlossen sind. Die Stromzuführung i o ist dabei räumlich so angeordnet, daß der Stromabnehmer 9 bei allen Bewegungen des Transformators, alsD auch den gleichen Bewegun-<gen des Ofens mit der Stromzuführung io, zuverlässig in Berührung bleibt.The arc furnace i is tiltable, with electrode holders 2 through connections 3, short flexible cables and connections 4. with rigid busbars 5, which are connected to the secondary side of a furnace transformer 6 are. The primary side of the transformer is stationary via connections 7 Holders 8 supported resilient current collectors 9 connected, which are formed approximately as follows can be like the pantographs of electric vehicles. Grind the pantographs 9 on power supply lines io, which are borne and isolated from a stationary frame i i are connected to the network 13 by corresponding connections 12. The power supply i o is spatially arranged so that the current collector 9 during all movements of the transformer, as well as the same movements of the furnace with the power supply io, reliably stays in touch.

Der die Bewegungen des Ofens mitmachende Transformator wird von dem Ofengerüst getragen, kann deshalb bis dicht an den Ofen herangeschoben sein, so daß die Verbindungsleitungen zwischen der Sekundärseite des Ofens und den Elektrodenhaltern ganz kurz gehalten werden können, wodurch ihre Verluste auch auf ein Mindestmaß herabgesetzt werden.The transformer that follows the movements of the furnace is controlled by the The furnace frame can therefore be pushed right up to the furnace, see above that the connecting lines between the secondary side of the furnace and the electrode holders can be kept very short, which also minimizes their losses be reduced.

Bei einem Ofen mit ausfahrbaren Elektrodenhaltern ist der Transformator in ähnlicher Weise angebracht; so daß er die Bewegungen der . Elektrodenhalt,er mitmacht, wobei der weitere Vorteil der Verkürzung der elektrischen Seitungen zwischen Ofen und Transformator erzielt wird.In the case of an oven with retractable electrode holders, the transformer is attached in a similar manner; so that he can see the movements of the. Electrode hold, he participates, with the further advantage of shortening the electrical sides between Furnace and transformer is obtained.
