Drosselspule für grosse Leistung, insbesondere zur Kurzschlussstrombegrenzung
EMI1.1

<Desc/Clms Page number 2>
allgemeinen die Verwendung eines natürlich viel schwächer bemessenen, in Fig. 2 dargestellten Innenzylinders--5-zweckmässig. Vom gleichen Gesichtspunkt aus erweist sich auch eine alle Scheibenspulen umfassende, ebenfalls in Fig. 2 dargestellte Bandage --9-- als zweckmässig, durch die ein gleichmässiger Druck der Keilflächen auf die Scheibenspulen bewirkt wird.
Gemäss einem weiteren Erfindungsgedanken wird das Aussenende der Keile (--3--) gabelförmig ausgebildet, so dass die Bandage--9--vorteilhaft gegen Abgleiten gesichert und unter entsprechend hohen Druck aufgebracht werden kann. Der erfindungsgemässe Aufbau einer Drosselspule für grosse Leistung vermeidet bzw. vermindert also den sehr ins Gewicht fallenden Aufwand für den Aussen-und Innenzylinder, erleichtert den massgerechten Aufbau und verhindert überdies, dass eine Überbeanspruchung der Festigkeit eines Konstruktionsteiles, welcher der Formveränderung der Scheibenspulen entgegenwirkt, zwangsläufig einen Totalschaden zur Folge hat.
PATENTANSPRÜCHE :
1. Drosselspule für grosse Leistung, insbesondere zur Kurzschlussstrombegrenzung, bestehend aus mehreren, einen ringförmigen Rotationskörper bildenden, von der Kreisform abweichenden
EMI2.1
Bandagen (6) versehen ist, die in einer oder mehreren zur Längsachse der Scheibenspulenform annähernd senkrechten Ebenen liegen und den formändernden Stromkräften der einzelnen Scheibenspulen entgegenwirken.

Choke coil for high performance, especially for short-circuit current limitation

generally the use of a naturally much weaker dimensioned inner cylinder, shown in Fig. 2 - 5-expedient. From the same point of view, a bandage encompassing all disc coils, also shown in FIG. 2, proves to be expedient, by means of which an even pressure of the wedge surfaces is effected on the disc coils.
According to a further idea of the invention, the outer end of the wedges (--3--) is fork-shaped, so that the bandage - 9 - can advantageously be secured against slipping and applied under correspondingly high pressure. The construction according to the invention of a choke coil for high performance avoids or reduces the very significant effort for the outer and inner cylinder, facilitates the dimensionally correct construction and also prevents overstressing of the strength of a structural part that counteracts the change in shape of the disc coils results in a total loss.
PATENT CLAIMS:
1. Choke coil for high power, in particular for short-circuit current limitation, consisting of several, an annular rotating body forming, deviating from the circular shape
EMI2.1
Bandages (6) are provided, which lie in one or more planes approximately perpendicular to the longitudinal axis of the disc coil shape and counteract the shape-changing current forces of the individual disc coils.
EMI2.2
