Description

Je höhere Anforderungen an die Meßgenauigkeit von Zählern gestellt werden, um so stärker machen sich die bisher kaum beachteten geringfügigen Unterschiede in den Bauelementen störend bemerkbar. So ist z B. eine genaue stroboskopische Eichung oder Prüfung bei vielen aus der Massenfertigung stammenden Zählern kaum durchführbar, -weil die Umlaufgeschwindigkeit des Zählerankers innerhalb einer Umdrehung schwankt. Die stroboskopischen Marken am Zähleranker stehen dann auch bei richtiger Einstellung nicht still, sondern führen Schwingungen aus, die die stroboskopischen Messungen erschweren. Diese Erscheinung ist auf verhältnismäßig geringfügige Ungleichmäßigkeiten in der Verteilung des Widerstandes des Läufers zurückzuführen. The higher demands placed on the measuring accuracy of meters The minor differences that have hitherto barely been considered are all the more pronounced noticeable disturbing in the components. Such is, for example, an accurate stroboscopic calibration or testing is hardly feasible for many meters from mass production, -because the speed of rotation of the meter armature fluctuates within one revolution. The stroboscopic marks on the counter anchor are then also with the correct setting not still, but carry out vibrations that make the stroboscopic measurements make more difficult. This phenomenon is due to relatively minor irregularities attributed to the distribution of resistance of the runner.

Die Erfindung hat die Aufgabe, diese Schwierigkeiten zu beseitigen. Zur Unterdrückung von ungleichförmigem Lauf von Zählerankern wird die Verteilung des Widerstandes des Ankers dadurch veränderbar gemacht, daß erfindungsgemäß in mindestens drei etwa radial verlaufenden Schlitzen des Ankers längs dieser verstellbare Widerstandsbrücken vorgesehen sind. Diese werden so lange verstellt, bis die störenden Erscheinungen verschwinden. Es empfiehlt sich, dabei austauschbare Brücken verschiedenen Widerstandes zu verwenden. The invention aims to overcome these difficulties. The distribution the resistance of the armature made changeable by the fact that according to the invention in at least three approximately radially extending slots of the armature adjustable along this Resistance bridges are provided. These are adjusted until the disturbing Appearances disappear. It is best to use different interchangeable bridges To use resistance.

Die Erfindung wird an Hand eines in der Zeichnung dargestellten Beispiels näher erläutert. The invention is illustrated using an example shown in the drawing explained in more detail.

Hier ist ein Scheibenanker eines Wechselstrom-oder Drehstromzählers dargestellt, der drei radiale Schlitze I hat. Die Schlitze können durch verstellbare Brücken 2 überbrückt werden. Man kann, wie erwähnt, austauschbare Brücken verschiedenen spezifischen Gewichtes und verschiedenen Widerstandes verwenden. Es wird sich stets eine solche Einstellung finden lassen, bei der die genannten Ungleichmäßigkeiten verschwinden. Here is a disc armature of an alternating or three-phase current meter shown, which has three radial slots I. The slots can be adjusted through Bridges 2 are bridged. As mentioned, you can use different interchangeable bridges specific gravity and different resistance. It will always be such a setting can be found in which the aforementioned irregularities disappear.

Die Erfindung bietet den Vorteil, daß bei der stroboskopischen Eichung, sobald für den jeweiligen Lastbereich die richtige Drehzahl eingestellt wird, die stroboskopischen Marken stillstehen und nicht wie bisher, namentlich bei kleinen Lasten, hin- und herschwingen. Die Einstellung des Prüflings auf Fehlerfreiheit wird dadurch wesentlich erleichtert. The invention offers the advantage that in the stroboscopic calibration, as soon as the correct speed is set for the respective load range, the stroboscopic brands stand still and not as before, especially with small ones Loads, swinging back and forth. The setting of the test item to ensure that it is free from defects this makes it much easier.

Scheibenförmige Zähleranker mit Ausnehmungen und auch Schlitzen sind an sich bekannt, doch dienen hier diese Mittel nicht zur Erzielung eines gleichmäßigen Ankerlaufs, sondern bei einem bekannten Drehstromzähler sollen die Durchbrechungen der Ankerscheibe eine störende Beeinflussung des einen Triebsystems durch streuende, vom anderen Triebsystem induzierte Ströme verhüten. Bei einem anderen bekannten Zähler soll im Gegensatz zum Erfindungsgegenstand absichtlich eine ungleichmäßige Verteilung des Drehmomentes auf den Ankerumfang herbeigeführt werden, damit der Anker bei abgeschalteter Stromspule stehenbleibt, also unter der Einwirkung des Spannungstriebflusses allein nicht leer läuft. Disk-shaped counter anchors with recesses and also slots are known per se, but here these means do not serve to achieve a uniform Armature run, but in a known three-phase meter, the breakthroughs the armature disk has a disruptive influence on one drive system through scattering, Avoid currents induced by the other instinctual system. With another well-known In contrast to the subject of the invention, the counter is intended to be an irregular Distribution of the torque are brought about on the armature circumference so that the Armature stops when the current coil is switched off, i.e. under the action of the The tension instinct flow alone does not run idle.
