Description

Regelbare Phasenabgleichung für Triebmagnete von Induktionsmeßgeräten Zusatz zum Patent 707657 In dem Patent 707 657 ist eine regelbare Phasenabgleichung für Triebmagnete von Induktionsmeßgeräten mit einer wenigstens einen Teil des - Triebmagnet,pfades umsdiliesenden Kurzschlußwicklung beschrieben, bei der die Rurzschlußwicklung mit einem parallelen Kraftlinienpfad mit regelbarem magnetischem Widerstand verkettet ist.Adjustable phase adjustment for drive magnets of induction measuring devices Addendum to patent 707657 In patent 707 657 there is an adjustable phase adjustment for driving magnets of induction measuring devices with at least part of the - Drive magnet, path surrounding short-circuit winding described in which the short-circuit winding concatenated with a parallel path of force lines with adjustable magnetic resistance is.

Erfindungsgemäß besteht wenigstens einer der parallelen Kraftlinienpfade aus einer sog. According to the invention, there is at least one of the parallel force line paths from a so-called

Wärmelegierung.Heat alloy.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. I ist der Hauptstrommagnet eines Induktionszählers mit der Wicklung 2. 10 ist der eine, II der andere parallele Pfad. Der magnetische Widerstand des Pfades 11 ist dadurch regelbar, daß der Pfadteil ii relativ zum Magnetkern 1, beispielsweise in die Stellung I IO, verschonen werden kann. 3 ist eine in Acht geschaltete Kurzschlußwicklung, deren untere Schleife 31 den Pfad 10 und deren obere Schleife 32 den Pfad 1I umschlingt. Der eine Pfad 10 hat Beilagen 100 aus einer Wärmelegierung. Statt dessen kann auch der Pfadteil 1 1 ganz oder teilweise aus einer Wärmelegierung bestehen. An exemplary embodiment of the invention is shown in the drawing. I is the main current magnet of an induction meter with winding 2. 10 is the one, II the other parallel path. The magnetic resistance of the path 11 is adjustable in that the path part ii relative to the magnetic core 1, for example in the position I IO, can be spared. 3 is a figure-eight short-circuit winding, whose lower loop 31 wraps around path 10 and whose upper loop 32 wraps around path 1I. One path 10 has shims 100 made from a thermal alloy. Instead, can also the path part 1 1 consist entirely or partially of a thermal alloy.

Da sich die magnetische Leitfähigkeit der Wärmelegierung in Abhängigkeit von der Temperatur ändert, ändert sich auch die Kraftlinienverteilung auf die beiden Pfade 10, 1 1. Since the magnetic conductivity of the heat alloy is dependent if the temperature changes, the distribution of the lines of force on the two also changes Paths 10, 1 1.

Je nach der Einstellung des magnetischen Widerstandes des Pfades II ergibt die durch die Wärmelegierung hervorgerufene Änderung der Flußverteilung eine schwächere oder stärkere Belastung des Flusses-durch die Sekundärwicklung und damit eine mehr oder weniger große Phasenvor- oder -nacheilung. Durch Verstellung des Pfadteils 11 kann nun in einfachster Weise der Zähler so abgeglichen werden, daß der Temperatureinfluß .uf die sog. innere Abgleichung des Zählers ausgebleichen wird. Der Temperatureinfluß auf die Größe des Drehmoments bzw. Bremsmoments kann dabei mit anderen bekannten Mitteln, z. B. durch Anbringung einer Wärmelegierung am Bremsmagnet, ausgeglichen werden.Depending on the setting of the magnetic resistance of path II the change in the flux distribution caused by the heat alloy results in a weaker or stronger load on the flux-through the secondary winding and thus a more or less large phase lead or lag. By adjusting the Path part 11 can now be adjusted in the simplest way, the counter so that the influence of temperature on the so-called internal adjustment of the meter will. The influence of temperature on the magnitude of the torque or braking torque can by other known means, e.g. B. by attaching a heat alloy at the brake magnet.

Die Erfindung bietet den Vorteil, daß sich bei der Eichung des Zählers eine hervorragende Unabhängigkeit der Zäblerangaben von der Raumtemperatur erzielen läßt. The invention offers the advantage that when calibrating the meter achieve an excellent independence of the zebbler information from the room temperature leaves.
