Description
Anordnung bei Zählern nach dem Induktionsprinzip zur Kompensierung der Fehler bei großer Last. Es ist bekannt, daß bei Zählern nach dem Induktionsprinzip die Fehler in den Angaben mit steigendem Strom stark ins Negative gehen. Die Ursache ist die mit dem Quadrate des Stromes zunehmende Dämpfung durch den Stromtriebfluß.Arrangement for counters based on the induction principle for compensation the bug with a heavy load. It is known that counters based on the induction principle the errors in the information go strongly into the negative with increasing current. The cause is the damping due to the current drive flow, which increases with the square of the current.
Es ist vorgeschlagen worden, diese Fehler durch Kurzschlußwindungen auf dem Stromeisen zu kompensieren, die dem Zähler einen starken sogenannten Stromvortrieb geben. Hiervon hat man jedoch so gut wie gar keinen Gebrauch gemacht, da diese Kurzschlußwindungen andere unangenehme Wirkungen zur Folge haben.It has been suggested to eliminate these faults by shorting turns to compensate on the electricity iron, which gives the meter a strong so-called current propulsion give. However, as good as no use has been made of this, since these short-circuit windings cause other unpleasant effects.
Auch ist versucht worden, durch sogenannte Nebenanschlüsse zum Stromeisen in Verbindung mit richtig bemessenen Luftspalten im Nebenschluß und im Gesamtflußkreis die großen Fehlerangaben bei hoher Last abzugleichen. Diese Anordnung bietet konstruktive Schwierigkeiten, die besonders in der genauen Innehaltung der erforderlichen Luftspalte liegen. -Die Nachteile dieser Anordnungen werden durch die Erfindung vermieden. In der Nähe der Scheibe werden zwischen die Schenkel des Stromeisens ein oder mehrere Brücken oder Stifte aus ferromagnetischem Material angeordnet, die einen Teil des Spannungsessens so durchsetzen, daß sie mit ihm- in ferromagnetischem Kontakt stehen. Es wird hierdurch erreicht, daß mit Anwachsen des Stromflusses die Sättigung in diesen Stiften in solchem Maße zunimmt, daß der vorher in den Stiften vorherrschende Spannungsfluß verdrängt und gezwungen wird, seinen Weg weniger durch die Stifte zu nehmen als durch den Luftspalt, in dem sich die Scheibe bewegt.Attempts have also been made to use so-called shunt connections to the electricity iron in connection with properly dimensioned air gaps in the shunt and in the overall flow circuit to compare the large error data with a high load. This arrangement offers constructive Difficulties, especially in keeping the required air gaps exactly lie. -The disadvantages of these arrangements are avoided by the invention. In the vicinity of the disk, between the legs of the current iron one or more Bridges or pins made of ferromagnetic material are arranged forming part of the Assert voltage measurements so that they are in ferromagnetic contact with it. It is thereby achieved that the saturation in these pins increases to such an extent that the one previously predominant in the pins Tension flow is displaced and forced to make its way less through the pins than through the air gap in which the disk moves.
Ein Ausführungsbeispiel der Erfindung geben die Abb. i und 2. Sie zeigen eine Anordnung eines Triebeisens mit gekreuztem Strom- und Spannungseisen. Dabei ist i das Spannungseisen, das mit einem Schenkel i durch die Öffnung des Stromeisens z hindurchragt und dessen Gegenpol 3 die Scheibe umfaßt. Mit q. sind die ferromagnetischen Stifte bezeichnet, deren Stirnseiten die Innenflächen der Schenkel des Stromeisens berühren. Die Stifte durchsetzen den Schenkel des Spannungseisens und werden hier in Bohrungen oder Aussparungen gehalten.An embodiment of the invention is shown in Figs. I and 2. They show an arrangement of a driving iron with crossed current and tension iron. Here i is the tension iron, which with one leg i through the opening of the current iron z protrudes and the opposite pole 3 includes the disk. With q. are the ferromagnetic Designates pins, the end faces of which are the inner surfaces of the legs of the current iron touch. The pins penetrate the leg of the tension iron and are here held in holes or recesses.
Querschnitt, Querschnittgestaltung und Material dieser Brücken oder Stifte sowie ihre Zahl sind an _und für sich beliebig und ein Ergebnis der experimentellen bzw. rechnerischen Untersuchungen.Cross-section, cross-sectional design and material of these bridges or Pens as well as their number are in and of themselves arbitrary and a result of the experimental or computational investigations.
,Diese Anordnung ist nicht an die dargestellte Sonderanordnung des Triebsystems gebunden, sondern ist sinngemäß auch bei anderen gekreuzten. oder gleichachsigen Triebsystemen anwendbar., This arrangement is not based on the special arrangement shown in the Instinctual system, but is also mutually crossed in others. or equiaxed Drive systems applicable.
