Description
Der Erfindungsgegenstand betrifft eine Zähleinrichtung für Überströme, insbesondere Blitzströme. Sie besteht aus einem hufeisen- oder ringförmigen als Magnet wirkenden Körper und einem Anker, die um einen Erdleiter herum angeordnet sind. Bei der einen Ausführungsform bestehen sowohl der Magnet als auch der Anker aus Hohlkörpern aus nichtmagnetischem Werkstoff, die mit Eisenfeilspänen oder Eisenpulver gefüllt sind. Bei der anderen Ausführungsform besteht der Magnet ebenfalls aus einem mit Eisenfeilspänen oder Eisenpulver gefüllten Hohlkörper aus nichtmagnetischem Werkstoff, der Anker dagegen aus in einem Behälter gelagerten Kugeln aus magnetischem Werkstoff.The subject matter of the invention relates to a Counter for overcurrents, especially lightning currents. It consists of a horseshoe or ring-shaped body acting as a magnet and an armature around a ground conductor are arranged around. In one embodiment, both the magnet and the armature consist of hollow bodies non-magnetic material filled with iron filings or iron powder. at In the other embodiment, the magnet also consists of one with iron filings or iron powder-filled hollow body made of non-magnetic material, the armature on the other hand, from balls made of magnetic material stored in a container.
Die Wirkungsweise der Anordnung ist folgende: Durch einen in dem Erdleiter fließenden Überstrom oder Blitzstrom wird der Inhalt des hufeisen- oder ringförmigen Hohlkörpers magnetisiert und der Anker durch die Pole des so entstandenen Magneten angezogen. Der Ausschlag des Ankers kann in bekannter Weise auf ein Zählwerk übertragen werden. Durch das Anschlagen des Ankers gegen die Pole des Magneten werden die Eisenfeilspäne durcheinandergeschüttelt und dadurch beide Hohlkörper entmagnetisiert und zur Messung bzw. Zählung neuer Stromstoße wieder geeignet gemacht.The mode of operation of the arrangement is as follows: Through a flowing in the earth conductor Overcurrent or lightning current is the content of the horseshoe-shaped or ring-shaped hollow body magnetized and the armature attracted by the poles of the resulting magnet. The deflection of the armature can be transferred to a counter in a known manner. By hitting the anchor The iron filings are shaken together against the poles of the magnet and as a result, both hollow bodies are demagnetized and used for measuring or counting new current impulses made suitable again.
Bei der anderen Ausführungsform werden die in einem Behälter gelagerten Kugeln von
dem Magneten einzeln angezogen und fallen in einen besonderen Sammelbehälter.
Durch Anordnung eines Gegengewichts oder einer mechanischen Gegenspannung am Anker bzw. durch einstellbare Anordnung des
Kugelbehiilters zu den Polen des Magneten kann man erreichen, daß nur Ströme einer
bestimmten Größe den Anker zum Ansprechen bringen.In the other embodiment, the balls stored in a container are individually attracted by the magnet and fall into a special collecting container.
By arranging a counterweight or a mechanical counter-tension on the armature or by means of an adjustable arrangement of the Kugelbehiilters to the poles of the magnet, one can achieve that only currents of a certain size cause the armature to respond.
Verbindet man den Anker an Stelle des Zählwerks mit einem anderen Stromkreis, so kann das Gerät auch für Relaiszwecke verwendet werden.If you connect the armature to another circuit instead of the counter, so the device can also be used for relay purposes.
In der Zeichnung sind zwei beispielsweise Ausführungsformen des Erfindungsgegenstandes dargestellt:The drawing shows two exemplary embodiments of the subject matter of the invention shown:
