Description

Vorrichtung zur stromproportionalen Kompensation magnetischer Störfelder bei Stromrichtergefäßen Gegenstand des Hauptpatents 971 4.09, ist eine Vorrichtung zur stromproportionalen Kompensation magnetischer Störfelder bei Stromrichtergefäßen, bei der entlang des Entladungsweges eine unsymmetrische Umhüllung des Lichtbogens durch Ferromagnetika angewendet ist, die außerhalb des Anodenschutzrohres liegen.Device for compensation of magnetic interference fields proportional to the current in the case of converter vessels, the subject of the main patent 971 4.09 is a device for current-proportional compensation of magnetic interference fields in converter vessels, in the case of an asymmetrical envelope of the arc along the discharge path is applied by ferromagnetics that are outside the anode protection tube.

Durch eine derartige Anordnung wird zusätzlich zu der kompensierenden Beeinflussung des Lichtbogens eine Abschirmung des äußeren. magnetischen Störfeldes erzielt. Jedoch muß, um die Sättigung bzw. die starke Abnahme der Perrneabilität dieser Umhüllung zu vermeiden und damit die abschirmende Wirkung zu erhalten, ein magne tischer Kurzschluß verhindert werden, d. h., die ferromagnetische Umhüllung weist einen Schlitz in ihrer Längsachse auf.Such an arrangement is in addition to the compensating Influencing the arc a shielding of the external. magnetic interference field achieved. However, in order to achieve saturation or a sharp decrease in permeability to avoid this envelope and thus to maintain the shielding effect magnetic short circuit can be prevented, d. i.e., the ferromagnetic envelope has a slot in its longitudinal axis.

Erfindungsgemäß beträgt nun bei einer Vorrichtung zur stromproportionalen Kompensation magnetischer Störfelder bei Stromrichtergefäßen nach Patent 971 4.o9 der Öffnungswinkel der Längsschlitze der Ferromagnetika je nach der Wandstärke 3o bis z$o°.According to the invention, in a device for the current proportional compensation of magnetic interference fields in converter vessels according to Patent 971 4.o9, the opening angle of the longitudinal slots of the ferromagnetic material is 3o to z $ o °, depending on the wall thickness.

Versuche ergaben nämlich, daß das im Innern der ferromagnetischen Umhüllung erregte Kompensationsfeld durch geeignete Wandstärke und Breite der Unsymmetrie (Längsschlitz) so ausgebildet werden kann, daB eine weitgehende Kompensation des magnetischen Störfeldes über den Entladungsquerschnitt erreicht wird.Experiments have shown that the inside of the ferromagnetic Envelopment excited compensation field by suitable wall thickness and broad the asymmetry (longitudinal slot) can be designed in such a way that an extensive Compensation of the magnetic interference field achieved via the discharge cross-section will.
