Description
Bei Elektrizitätszählern ist;es- notwendig, dem StromfluB eine Phasenverschiebung vom go0 gegenüber dem Spannungsfluß zu geben. Diese Phasenverschiebung wird durch entsprechende konstruktive Ausbildung und Bemessung der Kerne (magnetischer Nebenschluß, elektrische Belastung der Flüsse durch die Läuferscheibe usw.) erreicht, muß aber durch einen Feinabgleich auf den genauen Wert gebracht werden. Die bisher übliche Ausf,ührungsform dieses Feinabgleichs ist in Fig 1 und 2 in Vorderansicht bzw. Draufsicht dargestellt. Darin ist I das sogenannte Stromeisen eines Zählers, auf dessen Querjoch 2 sich eine Wicklung 3 befindet, die aus einer, meistens aber mehreren Windungen besteht. An den Enden dieser Wicklung ist ein schleifenartig ausgebildeter Widerstandsdraht 4 angelötet, auf dem eine Schelle 5 verschoben werden kann. Je nach Stellung dieser verschiebbaren Schelle wird die Wicklung mehr oder weniger kurzgeschlossen und damit die Phasenlage des Stromflusses verändert. In the case of electricity meters, it is necessary to phase shift the flow of electricity from the go0 compared to the voltage flow. This phase shift is due to Corresponding design and dimensioning of the cores (magnetic shunt, electrical load on the fluxes through the carrier disc etc.), but must can be brought to the exact value by fine adjustment. The usual one up to now The embodiment of this fine adjustment is shown in FIGS. 1 and 2 in a front view and top view, respectively shown. Here I is the so-called current iron of a meter, on its cross yoke 2 there is a winding 3, which consists of one, but mostly several turns consists. At the ends of this winding is a loop-like resistance wire 4 soldered on, on which a clamp 5 can be moved. Depending on the position of this sliding clamp, the winding is more or less short-circuited and thus the phase position of the current flow changed.
Phasenregeleinrichtungen dieser Art arbeiten zwar einwandfrei; wie jedoch aus Fig. I ersichtlich ist, kann man die Schelle nie völlig an die Wicklung heranführen, weil entweder die Hohlkehle der Lötstelle daran hindert oder weil der Widerstandsdraht kurz vor der Lötstelle abgekröpft ist oder weil die beiden Lötstellen in Verschiebungsrichtung der Schelle gegeneinander versetzt sind. In diesen Fällen bleibt in der einen Endstellung der Schelle ein kurzes Stückchen des Widerstandsdrahtes eingeschaltet und vermindert den Regelbereich. Phase control devices of this type work perfectly; how However, from Fig. I can be seen, you can never fully attach the clamp to the winding because either the fillet of the solder joint prevents it or because of the Resistance wire is bent just before the soldering point or because the two soldering points are offset from one another in the direction of displacement of the clamp. In these cases A short piece of the resistance wire remains in one end position of the clamp switched on and reduces the control range.
Um diesem Übelstand abzuhelfen, ist erfindungsgemäß die Widerstandsschleife so an die Wicklungsenden angelötet, daß sich die Schelle über die ganze Lötstelle hinwegschieben läßt. Die Aus--führung kann beispielsweise so getroffen sein, daß - die Enden der als Bandwicklung ausgeführten Wicklung stumpf an die Längskanten des Widerstandsdrahtes angelötet sind. In order to remedy this inconvenience, the resistance loop is according to the invention Soldered to the winding ends in such a way that the clamp extends over the entire solder joint can be pushed away. It can be implemented, for example, in such a way that - The ends of the winding designed as a tape winding butt to the longitudinal edges of the resistance wire are soldered.
Ein derartig ausgeführtes Ausführungsbeispiel der Erfindung ist in Fig. 3 und 4 dargestellt. Fig. 3 stellt einen Schnitt längs der Linie A-B in Fig. 4 dar. Die entsprechenden Teile sind mit denselben Bezugszeichen versehen wie in Fig. I und 2. Die Kurzschlußwicklung 3 ist hierbei als Bandwicklung ausgeführt, und ihre freien Enden sind stumpf an die Längskanten des Widerstands drahtes angelötet. An embodiment of the invention carried out in this way is shown in FIG Fig. 3 and 4 shown. Fig. 3 shows a section along the line A-B in Fig. 4. The corresponding parts are provided with the same reference numerals as in Fig. I and 2. The short-circuit winding 3 is designed here as a tape winding, and their free ends are butt soldered to the longitudinal edges of the resistance wire.
Die Widerstandsschelle 5 kann nunmehr über die ganze Lötstelle hinweggeschoben werden. Dadurch wird ein völliges Kurzschließen der Wicklung möglich, wodurch sich der Regelbereich erfahrungsgemäß aufß bis 70 erhöht gegenüber 2 bis 30 bei der bisher üblichen Ausführung. The resistance clamp 5 can now be pushed over the entire solder joint will. This enables the winding to be completely short-circuited, which leads to a Experience has shown that the control range is increased to 70 compared to 2 to 30 for the previous one usual execution.
