Description

Drosselspule zur Abdrosselung von Hochfrequenz im Zuge einer Hochspannungsleitung Um den telephonischen Verkehr mit Hochfrequenz auf Starkstromleitungen von Zustandsänderungen der Leitung unabhängig zu machen, werden in die Leistung an geeigneten Stellen Hochfrequenzsperrdrosselneingefügt. Mit Hilfe solcher Drosseln können beispielsweise auch Schaltoperationen, die betriebsmäßig an der Hochspannungsleitung stattfinden, unschädlich für den tele;phonis,chen Verkehr gemacht werden.Choke coil for reducing high frequency in the course of a high voltage line To the telephone traffic with high frequency on power lines from changes of state To make the line independent, high-frequency blocking chokes are inserted into the power at suitable points. With the help of such throttles, for example, switching operations that are operationally take place on the high-voltage line, harmless to telephonic traffic be made.

Da die Drosseln in der Hochspannungsleitung liegen, muß ihr Drahtquerschnitt dem Betriebsstrom dieser Leitung a;ngepaßt sein. Der Draht a der Leiter, aus welchem die Wicklung einer solchen Drosselspule hergestellt wird, muß also vergleichsweise großen Querschnitt erhalten. Infolgedessen werden, um eine genügende Induktivität und Sperrwirkung der Spulen zu erhalten, die Abmessungen der Spule, ihr Gewicht und auch ihre Raumbeanspruchung so;%vie die Herstellungskosten ,groß. Ferner werden umständliche Stützungen für solche Spulen notwendig, während für den Zweck gerade -ein leichtfies Gewicht, kleine Abmessungen, eine bequeme Handlichkeit und nicht zu hohe Herstellungskosten erwünscht sind.Since the chokes are in the high-voltage line, their wire cross-section must be adapted to the operating current of this line. The wire a the conductor from which the winding of such a choke coil is made, so must be comparative large cross-section. As a result, there will be enough inductance and locking effect of the coils to get the dimensions of the coil, its weight and also their space requirements so;% vie the manufacturing costs, great. Further be cumbersome supports for such coils necessary while straight for the purpose -A light weight, small dimensions, convenient handiness and not too high manufacturing costs are desirable.

Das Gewicht und die Abmessungen der Spulen lassen sich wesentlich verringern, wenn tnan die Spule gemäß der Erfindung mit einem Kern aus pulversüertem Eisen ausrüstet. Sie braucht alsdann bei ausreichender Induktivität nur wenige Wifin;dungen h,zpferdrabt zu tragen, so daß ihre Abmessun.geii und das Gewicht auf Größen kommen, die eine bequeme Handhabung und einfachen Einbau ermöglichen.The weight and dimensions of the coils can be significantly reduce when tnan the coil according to the invention with a core made of powdered Iron equips. If there is sufficient inductance, it then only needs a few windings h, to be carried by horse, so that their dimensions and weight come to sizes, which enable convenient handling and easy installation.

Es ist be'k.annt, in Radiogeräten Drosseln mit pulversiertem Eisenkern zu verwenden, uni durch die große Permeahilität und die geringen Energieverluste bestimmte Vorteile für die Hochfrequenz zu erzielen. Die Drosselspulen gemäß der Erfindung werden nicht in Rücksicht auf die Hochfrequenz und auch nicht in einer Hochfrequenzleitung, sondern in einer Leitung angeordnet, die die Frequenz des technischen Weichselstromes (5o Per. pro Sek.) fährt.It is well known to use chokes with a powdered iron core in radio sets to use, uni due to the high permeability and the low energy losses to achieve certain advantages for the high frequency. The choke coils according to the Invention are not in consideration of the high frequency and not in a High frequency line, but arranged in a line that corresponds to the frequency of the technical Vistula river (5o per sec.) Drives.
