Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung bezieht sich auf eine neue Konstruktion von Magnetkernen für Wechselstrom, die in mechanischer wie elektrischer Hinsicht besondere Vorteile bietet.
Das Wesentliche der neuen Erfindung besteht, wie in der Figur gezeigt ist, darin, daß mehrere geschlitzte und mit Isolierlack überzogene Rohrstücke ineinandergeschoben sind und auf diese Weise allein oder in Verbindung mit anderen bekannten Elementen, z. B. einem Drahtbündel in der Mitte, den zylindrischen Magnetkern bilden.
The invention relates to a new construction of magnetic cores for alternating current, which offers particular advantages in mechanical and electrical terms.
The essence of the new invention, as shown in the figure, is that several slotted and coated with insulating lacquer pipe pieces are pushed into each other and in this way alone or in connection with other known elements, for. B. a wire bundle in the middle to form the cylindrical magnetic core.

Die Herstellung solcher Magnetkerne wird dadurch sehr einfach und billig, daß man die im Handel erhältlichen normalen geschlitzten und lackierten Peschelrohre auf die richtige Länge schneidet und ineinandersteckt. Dabei braucht das Festhalten der einzelnen Rohrstücke nur durch die natürliche Klemmwirkung der etwas zusammengebogenen Schlitzrohre zu erfolgen. Die Isolation kann auch auf andere Weise als durch Lack, ζ. Β. durch Zwischenschichten isolierenden Materials, erzielt werden.The production of such magnetic cores is very simple and cheap that you have the commercially available normal slotted and painted Peschel pipes on the correct one Length cuts and nests. You need to hold on to the individual pieces of pipe only through the natural clamping effect of the slightly bent slotted tubes to be done. The insulation can also be done in a way other than lacquer, ζ. Β. by Intermediate layers of insulating material can be achieved.

Außer der einfachen Herstellung bieten diese Magnetkerne den Vorteil, daß sie von vornherein genau zylindrisch sind, so daß eine weitere Bearbeitung wegfällt.In addition to the simple production, these magnetic cores have the advantage that they are of are exactly cylindrical from the start, so that no further processing is necessary.

In elektrischer Beziehung wird die Größe der entstehenden Wirbelströme infolge der vielfachen Unterbrechung des Stromweges wirksam vermindert, zumal auch infolge des Schlitzes die Wirbelströme selber keinen geschlossenen Kreis vorfinden.In an electrical relationship, the size of the eddy currents produced is due to the Multiple interruptions in the current path effectively reduced, especially as a result of the Slot the eddy currents themselves do not find a closed circuit.

Durch die auf diese Weise erzielte Unterteilung des Eisens des Magnetkernes, wie er z. B. in dieser Form für Bogenlampenregulierwerke und ähnliche Apparate für Wechselstrom besonders zweckmäßig ist, wird auch die Zugkraft des Magneten um ein Vielfaches erhöht.Through the subdivision of the iron of the magnetic core achieved in this way, like him z. B. in this form for arc lamp regulators and similar apparatus for alternating current is particularly useful, the pulling force of the magnet is increased many times over.
