Description

Drosselspule mit Eisenkern für kurzzeitige Beanspruchung des magnetischen Materials Man unterscheidet bei Drosselspulen mit Eisenkern solche, die einen vollen Eisenkern, und solche, die einen fein unterteilten Eisenkern besitzen. Die Drosselspulen mit vollem Eisenkern haben keine wesentliche: Strombegrenzung zur Folge, können aber durch die in dem massiven Kern entstehenden Wirbelströme dazu dienen, um höhere überspannungen bei Abschaltungen zu vermeiden. Die Drosselspulen mit fein unterteilten Eisenkernen haben ihrerseits wieder eine große strombegrenzende Wirkung zur Folge, während sie aber Überspannungen abzudrosseln nicht in der Lage sind, weil in ihnen keine Wirbelstrombildung wie in einem vollen Eisenkern auftreten kann.Choke coil with iron core for short-term use of the magnetic Materials A distinction is made between inductors with an iron core and those that have a full core Iron core, and those that have a finely divided iron core. The reactors with a full iron core do not have any essential: current limitation result, can but due to the eddy currents arising in the massive core serve to generate higher ones avoid overvoltages during shutdowns. The choke coils with finely divided Iron cores in turn have a great current-limiting effect, while they are not able to throttle off overvoltages because in them no eddy current formation can occur as in a full iron core.

Gemäß der Erfindung wird eine Drosselspule geschaffen, die beide Vorteile, insbesondere bei ihrer Verwendung zur Strombegrenzung oder zu Abschaltzwecken, in sich vereinigt, indem der Eisenkern ganz oder teilweise aus grob unterteiltem Eisen, wie Schrotteilen, Drehspänen, Förder- oder sonstigen Drahtseilen, oder Alteisenteilen besteht. Dadurch wird bei Einschaltung einer solchen Drosselspule in einen Abschaltestromkreis infolge der groben Unterteilung in der Drosselspule Wirbelstrom erzeugt, der die Überspannungen herabsetzt und andererseits infolge der immerhin noch vorhandenen Unterteilung strombegrenzende Wirkungen erzielt.According to the invention, a choke coil is created which has both advantages especially when used for current limitation or for shutdown purposes, in unites in that the iron core is wholly or partly made of roughly divided iron, such as scrap parts, turnings, conveyor or other wire ropes, or scrap iron parts consists. As a result, when such a choke coil is switched on, it becomes a switch-off circuit due to the coarse subdivision in the choke coil, eddy currents are generated which the Reduces overvoltages and on the other hand as a result of the still existing Subdivision achieved current-limiting effects.

Zur Herstellung des Kernes gemäß der Erfindung können billig zu beschaffende Eisenteile von entsprechender Größe, z. B. Schrottteile, Drehspäne, Förder- oder sonstige Drahtseile, benutzt werden. Eine Isolierung der Teile untereinander kann erfolgen, jedoch wird in vielen Fällen die künstliche oder natürliche Oxydation an den Eisenteilen zur Isolierung genügen. Zur Verstärkung der erwünschten Wirkungen können die einzelnen Eisenteile auch miteinander leitend verbunden werden.To manufacture the core according to the invention can be cheaply procured Iron parts of appropriate size, e.g. B. scrap parts, turnings, conveyor or other wire ropes can be used. Isolation of the parts from one another can be take place, but in many cases artificial or natural oxidation is used on the iron parts are sufficient for insulation. To reinforce the desired effects the individual iron parts can also be conductively connected to one another.
