Description

Ferraris-Triebeisen mit ferromagnetischem Nebenschlaß Es ist bekannt, die Fehlerkurve von Ferraris-Zählern durch einen parallel zum Stromtriebfluß liegenden ferromagnetischen Nebenschluß zu verbessern. Die Wirkungsweise solcher Anordnungen beruht darauf, daß das Nebenschlußeisen sich bei zunehmender Belastung mehr und mehr sättigt, so daß der wirksame Stromtriebfluß stärker als proportional mit der Belastung wächst, wodurch es möglich ist, die durch die Triebflüsse hervorgerufene Eigendämpfung, die bei Belastungen von mehr als ioo Prozent große Minusfehler zur Folge hätte, teilweise zu kompensieren.Ferraris drive irons with ferromagnetic shunt It is known the error curve of Ferraris meters through a parallel to the current drive flow improve ferromagnetic shunt. How such arrangements work is based on the fact that the shunt iron moves more and more with increasing load saturates more, so that the effective current drive flow is stronger than proportional with the The load increases, which makes it possible to reduce the strain caused by the instinctual flows Self-damping, which leads to large minus errors when loads are greater than 100 percent Result would have to partially compensate.

Nach der Erfindung werden an Stelle eines einzigen ferromagnetischen Nebenschlusses zwei oder mehrere solcher Nebenschlußwege vorgesehen, welche so bemessen bzw. so angeordnet werden, daf sie sich bei verschiedenen Graden der Belastung sättigen. Durch die vereinigte Wirkung der Sättigungsvorgänge in allen Nebenschlüssen kann, wie sich bei Versuchen gezeigt hat, die Kompensation der Eigendämpfung viel weiter getrieben werden, als dies bei Anwendung eines einzigen ferromagnetischen Nebenschlusses möglich ist.According to the invention, instead of a single ferromagnetic Shunt two or more such shunt paths provided, which are sized or arranged in such a way that they are saturated at different levels of exposure. Due to the combined effect of the saturation processes in all shunts, As has been shown in tests, the compensation of the self-damping goes much further be driven than this when using a single ferromagnetic shunt is possible.

Die Sättigungsverhältnisse in den einzelnen iebenschlüssen können in bekannter Weise durch Einschaltung von geeigneten Luftwegen oder von Strecken aus unmagnetischem Material sehr leicht so abgestimmt werden, .daß die angestrebte Gesamtwirkung erreicht wird.The saturation conditions in the individual connections can in a known manner by using suitable airways or routes made of non-magnetic material can be easily adjusted so that the desired Overall effect is achieved.

In der Abbildung ist ein Ausführungsbeispiel einer solchen Anordnung schematisch dargestellt. a sind hierbei die beiden Strompole; b und c sind ferromagnetische Nebenschlüsse, über welche sich ein Teil des aus den Strompolen austretenden Stromtriebflusses schließt. Die Eisenwege dieser Nebenschlüsse sind durch Strecken d' und d2 aus unmagnetischem Material unterbrochen. Hierbei sind sowohl die Eisenwege b und c als auch die Zwischenlagen dl und d2 verschieden bemessen, so daß den beiden Nebenschlüssen verschiedene magnetische Sättigungscharakteristiken zukommen, Da der Einfluß der Nebenschlüsse auf die Überlastfehlerkurve des Zählers durch die vereinigte Wirkung beider Charakteristiken bestimmt ist, lassen sich durch entsprechende Abmessungen der Teile b und c die Sätti= gungsverhältnisse in beiden Nebenschlüssen leicht so abstimmen, daß die angestrebte Gesamtwirkung, nämlich die Kompensation der durch die Triebflüsse hervorgerufenen Eigendämpfung, erreicht wird.The figure shows an embodiment of such an arrangement shown schematically. a are the two current poles; b and c are ferromagnetic Shunts through which part of the current drive flow emerging from the current poles is distributed closes. The iron paths of these shunts are made of non-magnetic by stretches d 'and d2 Material interrupted. Here are both the iron paths b and c and the intermediate layers dl and d2 are dimensioned differently, so that the two shunts have different magnetic Saturation characteristics come because the influence of the shunts on the overload error curve of the counter is determined by the combined effect of both characteristics The saturation ratios are determined by the corresponding dimensions of parts b and c easily vote in both shunts so that the desired overall effect, namely the compensation of the self-damping caused by the instinctual flows, is achieved.
