Description

Bei der Phasenabgleichung von Induktionszählern verwendet man oft auf dem Triebmagneten sitzende Sekundärwichlungen mit regelbarem Widerstan.d. One often uses when phasing induction counters Secondary windings sitting on the drive magnet with adjustable resistance d.

Die Sekundärwicklung ist zu diesem Zweck an eine Widerstandsdrahtschleife angeschlossen, längs der eine Kontaktbrücke verstellt werden ka.nn. Die Kontaktbrüdce besteht in. der Regel aus einem Futterteil und einer Schraube, zwischen. denen das parallele Drähtepaar der Schleife eingeklemmt werden kann.The secondary winding is connected to a resistance wire loop for this purpose connected, along which a contact bridge can be adjusted. The contact brother usually consists of a chuck part and a screw, between. which that parallel wire pair of the loop can be pinched.

Lästig bei diesen Abgleichvorrichtungen ist, daß der Widerstand nicht stetig geändert werden kann denn beim Lockern der Schraube geht der Kontakt verloren. Der Widerstand ist dann. entsprechend groß. Erst wenn nach dem Verschiehen der Kontaktbrücke die Schraube wieder angezogen wird, hat er wieder eine der Drahtlänge entsprechende Große. Dies ist besonders bei der stroboskopischen Eichung von Zählern störend. It is annoying with these balancing devices that the resistance is not Can be changed continuously because the contact is lost when the screw is loosened. The resistance is then. correspondingly large. Only if after moving the contact bridge the screw is tightened again, it has a length corresponding to the wire length Size. This is particularly troublesome with the stroboscopic calibration of meters.

Die Erfindung hat die Aufgabe, möglichst unter Beibehaltung dieser einfachen Bauform der Abgleichvorrichtung diese Mängel zu beseitigen. Bei einem Abgleichwiderstand mit längs eines Drahtes verschiebbarem und feststellbarem Kontakt ist erfindungsgemäß zwischen dem zum Feststellen dienenden Organ und dem Draht ein elastisches Glied solcher Vorspannung angeordnet, daß bei gelockertem Feststellorgan einerseits der für den Stromübergang erforderliche Kontaktdruck herrscht, andererseits eine zügige Verschiebung des Kontaktes möglich ist. Es bleibt also beim Lockern des Feststellorgans der Kontaktdruck und damit die bisherige Größe des Widerstandes erhalten. Beim Verschieben des Kontaktes ändert sich der Widerstand stetig. Er nimmt auch beim Wiederanziehell des Feststel lorgans n.icht ab. Die Abgleichvorrichtung läßt sich also viel rascher und bequemer auch bei Anwendung einer stroboskopischen Eicheinrichtung auf den richtigen Wert einstellen. The invention has the task of keeping this as possible simple design of the adjustment device to eliminate these deficiencies. At a Balancing resistor with a contact that can be moved and locked along a wire is, according to the invention, between the organ used for determining and the wire elastic member arranged such bias that when the locking member is loosened on the one hand the contact pressure required for the current transfer prevails, on the other hand a rapid shift of the contact is possible. So it stays with loosening of the locking member, the contact pressure and thus the previous size of the resistance obtain. When the contact is moved, the resistance changes steadily. He takes not even when the locking organ is tightened again. The balancing device can therefore be much quicker and more convenient, even when using a stroboscopic Set the calibration device to the correct value.

Die Erfindung wird an Hand der Zeichnung näher erläutert (Fig. I und 2). The invention is explained in more detail with reference to the drawing (Fig. I. and 2).

Zwei parallele Widerstandsdrähte I sind durch eine aus einem Mutterteil 2 und eine Schraube 3 bestehende, verschiebbare Koitaktbrücke überbrückt. Zwischen dem Schraubenkopf 4 und den Drähten I ist eine gekrümmte, in der angegebenen Weise vorgespannte Blattfeder 5 angeordnet, die von der Schraube 3 durchdrungen ist und zwischen zur Drahtführung dienende Vorsprünge 6 des Mutterteils 2 greift. Sie stützt sich mit ihrer Mitte gegen den Schraubenkopf, mit ihren Enden gegen die Drähte. Two parallel resistance wires I are through one from a nut part 2 and a screw 3 bridged existing, displaceable Koitaktbrücke. Between the screw head 4 and the wires I is a curved one in the manner indicated arranged prestressed leaf spring 5, which is penetrated by the screw 3 and between projections 6 of the nut part 2 which serve to guide the wire. She supports with their center against the screw head, with their ends against the wires.
