Description
Die Induktivität eines gekühlten Hochstromkabels erhöhender LeiterabschnittConductor section increasing the inductance of a cooled high-current cable
Die Erfindung betrifft einen die Induktivität eines gekühlen Hochstromkabels erhöhenden Leiterabschnitt.The invention relates to a conductor section that increases the inductance of a cooled high-current cable.
Etwa beim Betreiben von Drexphasenlichtbogenofen stellt sich das Problem, daß bei in einer Ebene angeordneten Tragarmen für die Elektroden der mittlere Strompfad eine geringere Induktivität aufweist als die äußeren Strompfade. Zur Behebung der sogenannten Reaktanzasymmetrie ist unter anderem vorgeschlagen worden, in den mittleren Strompfad eine die Reaktanzasymmetrie eliminierende Reaktanzschleife einzufügen (DE-PS 35 16 940). Bei den vielfach vorliegenden räumlich beengten Bedingungen sind mit dem Einsatz der Reaktanzschleife Probleme verbunden.When operating three-phase arc furnaces, for example, the problem arises that, when the electrode support arms are arranged in one plane, the middle current path has a lower inductance than the outer current paths. To eliminate the so-called reactance asymmetry, it has been suggested, among other things, to insert a reactance loop into the middle current path that eliminates the reactance asymmetry (DE-PS 35 16 940). In the often cramped conditions, the use of the reactance loop is associated with problems.
Ausgehend vom Stand der Technik liegt der Erfindung in erster Linie die Aufgabe zugrunde, für die Behebung der Reaktanzasymmetrie eine raum- bzw. platzsparende Lösung anzubieten. Based on the state of the art, the invention is primarily based on the task of offering a space-saving solution for eliminating the reactance asymmetry.
Die Aufgabe wird mit einem die Induktivität eines gekühlten Hochstromkabels erhöhenden Leiterabschnitt gelöst, der erfindungsgemäß entsprechend dem kennzeichnenden Teil des Anspruches 1 ausgebildet ist.The object is achieved with a conductor section which increases the inductance of a cooled high-current cable and which is designed according to the invention in accordance with the characterizing part of claim 1.
Durch die den Leiterabschnitt umgebende, gegenüber dem Leiter isolierte Eisenhülse erfolgt eine Erhöhung der Induktivität in dem Hochstromkabel, dem der Leiterabschnitt zugeordnet ist. Querschnitt, Wandstärke und/oder Länge derThe iron sleeve surrounding the conductor section and insulated from the conductor increases the inductance in the high-current cable to which the conductor section is assigned. Cross-section, wall thickness and/or length of the
Eisenhülse bestimmen die durch den erfindungsgemäßen Leiterabschnitt erzeugte Zusatzinduktivität und werden den jeweiligen Erfordernissen Rechnung tragend gewählt- Der die Induktivität erhöhende Leiterabschnitt läßt sich raumsparend in den Strompfad einfügen, dessen Induktivität der Erhöhung bedarf. Der neue Leiterabschnitt läßt sich dann auch leichter und kostengünstiger fertigen als etwa eine Reaktanzschleife.Iron sleeves determine the additional inductance generated by the conductor section according to the invention and are selected to take the respective requirements into account. The conductor section that increases the inductance can be inserted into the current path whose inductance needs to be increased in a space-saving manner. The new conductor section can then also be manufactured more easily and more cost-effectively than, for example, a reactance loop.
Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen 1 bis 8.Embodiments of the invention emerge from the subclaims 1 to 8.
In der Zeichnung ist die Erfindung weitergehend erläutert.The invention is further explained in the drawing.

Der Leiterabschnitt in Figur 1 besteht aus dem aus einer Mehrzahl von verdrillten Kupferadern 111, 112... gebildeten Vollleiter 11, der an seinen Enden mit Anschlußstücken 12 und 12' versehen ist, über die die Verbindung zum Hochstromkabel hergestellt wird. Ein Teilbereich des Leiters 11 ist von einer Eisenhülse 13 umgeben. Die Endbereiche der Hülse 13 werden von von den AnschlußstückenThe conductor section in Figure 1 consists of the solid conductor 11 formed from a plurality of twisted copper wires 111, 112..., which is provided at its ends with connectors 12 and 12', via which the connection to the high-current cable is made. A portion of the conductor 11 is surrounded by an iron sleeve 13. The end areas of the sleeve 13 are surrounded by the connectors
12 und 12' ausgehenden Schlauchabschnitten 14 und 14' übergriffen, die auf den Anschlußstücken 12 und 12" sowie auf der Eisenhülse 13 mittels Schellen 16 festgelegt sind. Mit 121 sind Kanäle in den Anschlußstücken 12, 12' bezeichnet, durch die das Kühlmittel zu- bzw. abgeleitet wird.12 and 12', which are secured to the connectors 12 and 12" and to the iron sleeve 13 by means of clamps 16. 121 designates channels in the connectors 12, 12', through which the coolant is supplied or discharged.
Wie aus den Figuren 2 und 3 ersichtlich ist, sind der Eisenhülse 13 Distanzhülsen 17, 17' aus nichtleitendem Material zugeordnet, die einen Kontakt zwischen dem Leiter 11 und der Eisenhülse 13 unterbinden. Diese Distanzhülsen 17, 17' weisen zwecks Belassung eines Durchgangs für das Kühlmittel eine lichte Weite auf, die größer ist als der Querschnitt des Leiters 11. Die Distanzhülsen 17 und 17* sind eingelagert in Rücksprünge 131, 131' in der Eisenhülse 13. Die in den Endbereich der Eisenhülse 13 angesetzten Distanzhülsen 17' weisen überdies eine Schulter 171 auf, mit der sie gegen die jeweilige Stirnseite der EisenhülseAs can be seen from Figures 2 and 3, the iron sleeve 13 is provided with spacer sleeves 17, 17' made of non-conductive material, which prevent contact between the conductor 11 and the iron sleeve 13. In order to leave a passage for the coolant, these spacer sleeves 17, 17' have a clear width that is larger than the cross-section of the conductor 11. The spacer sleeves 17 and 17* are embedded in recesses 131, 131' in the iron sleeve 13. The spacer sleeves 17' placed in the end area of the iron sleeve 13 also have a shoulder 171 with which they are pressed against the respective end face of the iron sleeve.
13 zur Anlage kommen.13 come to the facility.
Querschnitt, Wandstärke und/oder Länge der Eisenhülse 13 werden im Hinblick auf die im Einzelfall gewünschte bzw. erforderliche Zusatz-Induktivität gewählt.The cross-section, wall thickness and/or length of the iron sleeve 13 are selected with regard to the additional inductance desired or required in the individual case.
Die in den Figuren 4 und 5 wiedergebene Aus führungs form unterscheidet sich von der Ausführungsform nach den FigurenThe embodiment shown in Figures 4 and 5 differs from the embodiment shown in Figures
1 bis 3 lediglich darin, daß der Leiter 21 ein Hohlleiter ist, der aus auf einem tragenden Rohr 22 aufgebrachten Adern 211, 212... gebildet ist, (insbesondere Figur 5). Ein entsprechender Leiterabschnitt kommt zum Einsatz, wenn sich eine stärkere Kühlung des Hochstromkabels als erforderlich erweist.1 to 3 only in that the conductor 21 is a waveguide formed from wires 211, 212... applied to a supporting tube 22 (in particular Figure 5). A corresponding conductor section is used if a stronger cooling of the high-current cable proves to be necessary.
