Abstract

1. Contact arrangement for tap selectors of tapped transformers for the selective bridging-over of an inner contact ring (1) with tap contacts (5) arranged on an outer circle, with the following features : - two contact bridges (2, 3), which lie opposite each other and are pressable against each other by springs (4) of flat material, each lie constantly by a respective end (21, 31) against the contact ring (1), - the contact bridges are pivotable laterally from tap contact (5) to tap contact, - the contact ring (1) is encompassed by the inwardly fromed ends (21, 31) of both the contact bridges in such a manner that two contact places (6 or 7), lying one behind the other in longitudinal direction of the contact bridges, are present each time at the contact ring (1), - the tap contacts (5) are constructed as contact rods (5) of substantially round cross-section and extending in longitudinal direction of the contact bridges, - the free ends (22, 32) of both the contact bridges (2, 3) between them in the switched state receive a tap contact (5) by means of V-shaped inward formations, in such a manner that two contact places (8 or 9), which are displaced through 90 degrees at the contact ring relative to the contact places (6 or 7), respectively are likewise present, - the free ends of the contact bridges (2, 3) are provided with run-up surfaces (10 or 11) bent away outwardly for the better running-up onto the contact rod (5), - all contact places (6, 7, 8, 9) to be formed by the contact bridges (2, 3) are formed as raised stamped portions, characterised thereby, that the middle part of each contact bridge (2, 3) does not participate in the contact making and displays a cross-section which is bowed towards the other contact bridge, wherein both the bowed surfaces of both the contact bridges lie one against the other in the un-switched state and are rollable one on the other during the running-up onto the contact rod (5).

Description

Die Erfindung betrifft eine Kontaktanordnung für Stufenwähler von Stufentransformatoren, wie sie im Oberbegriff des Patentanspruches näher bezeichnet ist. Derartige Kontaktanordnungen sind bekannt: DE-PS 11 70 040.The invention relates to a contact arrangement for step selectors of step transformers, as described in the preamble of the claim. Such contact arrangements are known: DE-PS 11 70 040.

Eine Schwierigkeit bei derartigen Kontaktanordnungen liegt darin, daß beim Auflaufen der Kontaktbrücken auf einen feststehenden Kontaktstab die beiden Kontaktbrücken unter Überwindung der Kontaktdruckfedern auseinandergedrückt werden müssen, bevor sie mit ihrer V-förmigen Einformung den feststehenden Kontaktstab umgreifen. Dies stellt erhebliche Anforderungen an den Antrieb des Stufenwählers und führt natürlich auch zu Verschleißerscheinungen.A difficulty with such contact arrangements is that when the contact bridges run onto a fixed contact rod, the two contact bridges have to be pressed apart by overcoming the contact pressure springs before they grip the fixed contact rod with their V-shaped indentation. This places considerable demands on the drive of the step selector and, of course, also leads to signs of wear.

Aufgabe der Erfindung ist es, die eingangs näher bezeichnete Kontaktanordnung zu verbessern, um insbesondere mit geringeren Antriebskräften auszukommen und um damit den Verschleiß so gering wie möglich zu halten. Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Patentanspruches angegebenen Mittel gelöst.The object of the invention is to improve the contact arrangement described in more detail at the outset, in order in particular to make do with lower driving forces and thus to keep the wear as low as possible. This object is achieved by the means specified in the characterizing part of the claim.

Der mit der Erfindung erzielte Vorteil liegt insbesondere darin, daß sich ein mit der erfindungsgemäßen Kontaktanordnung ausgerüsteter Stufenwähler gegenüber anderen Stufenwählern leichter betätigen läßt und daß infolge dessen auch der Verschleiß gering gehalten werden kann, wodurch die mechanische Lebensdauer vergrößert wird.The advantage achieved by the invention is, in particular, that a step selector equipped with the contact arrangement according to the invention can be operated more easily than other step selectors and that, as a result, wear can also be kept low, which increases the mechanical life.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen

  • Figur 1 die Kontaktanordnung im Moment des Auflaufens auf einen feststehenden Kontaktstab (ohne Kontaktdruckfedern),
  • Figur 2 dieselbe Kontaktanordnung im geschalteten Zustand,
  • Figur 3 einen Querschnitt durch den nicht an der Kontaktgabe beteiligten Mittelteil der beiden Kontaktbrücken,
  • Figur 4 eine Seitenansicht der Kontaktanordnung und
  • Figur 5 die Kontaktgabe am Kontaktstab.
An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it
  • FIG. 1 shows the contact arrangement at the moment it hits a fixed contact rod (without contact pressure springs),
  • FIG. 2 shows the same contact arrangement in the switched state,
  • FIG. 3 shows a cross section through the middle part of the two contact bridges which is not involved in making contact,
  • Figure 4 is a side view of the contact arrangement and
  • Figure 5 shows the contact on the contact rod.

Wie aus den Figuren ersichtlich, besteht die Kontaktanordnung im wesentlichen aus einem Kontaktring 1, aus zwei sich gegenüberliegenden Kontaktbrücken 2, 3 mit zugehörigen Kontaktdruckfedern 4 sowie aus mehreren radial zum Kontaktring angeordneten feststehenden Kontaktstäben 5, von denen der Übersichtlichkeit wegen jedoch nur einer dargestellt ist. Der Kontaktring 1 wird auf übliche Weise von einer Wählersäule, die auch die elektrischen Verbindungsleitungen aufnimmt, gehalten, während die feststehenden als Kontaktstäbe 5 ausgebildeten Stufenkontakte auf übliche Weise an einem Gerüst aus Isolierstäben, die koaxial zur Wählersäule angeordnet sind, sitzen. Diese Dinge sind jedoch im einzelnen nicht dargestellt, da sie für das Verständnis der vorliegenden Erfindung nicht erforderlich sind.As can be seen from the figures, the contact arrangement essentially consists of a contact ring 1, two opposing contact bridges 2, 3 with associated contact pressure springs 4 and a plurality of fixed contact rods 5 arranged radially to the contact ring, of which only one is shown for the sake of clarity. The contact ring 1 is held in the usual way by a selector column, which also accommodates the electrical connecting lines, while the fixed step contacts designed as contact rods 5 are seated in the usual way on a frame made of insulating rods which are arranged coaxially to the selector column. However, these things are not shown in detail since they are not necessary for an understanding of the present invention.

Die seitlich in Pfeilrichtung verschwenkbaren Kontaktbrücken 2, 3 liegen mit je einem Ende 21, 31 ständig am Kontaktring 1 an. Diese Enden 21, 31 sind derartig geformt, daß der Kontaktring 1 umgriffen wird, wobei sich durch zusätzliche Anprägungen jeweils zwei Kontaktstellen 6 bzw. 7 am Kontaktring bilden, die in Bezug auf die Längsachse der Kontaktbrücke hintereinander liegen. Die freien Enden 22, 32 der beiden Kontaktbrücken 2, 3'liegen mittels V-förmiger Einformungen im geschalteten Zustand am Kontaktstab 5 an, wobei ebenfalls durch entsprechende Anprägungen je zwei Kontaktstellen 8 bzw. 9 gebildet werden, die gegenüber den Kontaktstellen 6 bzw. 7 am Kontaktring 1 um etwa 90° versetzt sind. Die freien Enden 22, 23 der beiden Kontaktbrücken 2, 3 sind dann weiter mit abgebogenen Auflaufflächen 10, 11 versehen, um ein besseres Auflaufen auf den feststehenden Kontaktstab 5 zu ermöglichen. Wie insbesondere aus Figur 3 ersichtlich, weist der nicht an der Kontaktgabe beteiligte Mittelteil jeder Kontaktbrücke 2, 3 einen zur anderen Kontaktbrücke hin gewölbten Querschnitt auf, wobei die beiden gewölbten Oberflächen beider Kontaktbrücken 2, 3 im nicht geschalteten Zustand gegeneinander liegen und infolge der angeprägten Kontaktstellen 6 bzw. 7 eine instabile Lage einnehmen, so daß sie leicht aneinander abwälzbar sind. Hierbei erfolgt praktisch ein Kippen um die angeprägten Kontaktstellen 6 bzw. 7.The contact bridges 2, 3, which can be pivoted laterally in the direction of the arrow, are always at one end 21, 31 on contact ring 1. These ends 21, 31 are shaped such that the contact ring 1 is encompassed, two contact points 6 and 7 respectively forming on the contact ring due to additional impressions, which lie one behind the other with respect to the longitudinal axis of the contact bridge. The free ends 22, 32 of the two contact bridges 2, 3 ′ rest against the contact rod 5 in the switched state by means of V-shaped indentations, two contact points 8 and 9 also being formed by corresponding impressions, which are opposite the contact points 6 and 7 are offset by approximately 90 ° on contact ring 1. The free ends 22, 23 of the two contact bridges 2, 3 are then further provided with bent contact surfaces 10, 11 in order to enable better contact with the fixed contact rod 5. As can be seen in particular from FIG. 3, the middle part of each contact bridge 2, 3 which is not involved in making contact has a cross section which is curved toward the other contact bridge, the two curved surfaces of both contact bridges 2, 3 lying against one another in the non-switched state and as a result of the stamped contact points 6 or 7 assume an unstable position, so that they can be easily passed on to each other. This practically involves tilting around the stamped contact points 6 and 7.

Werden, wie insbesondere aus Figur 1 ersichtlich, die beiden Kontaktbrücken 2, 3 durch seitliches Verschwenken mit dem Kontaktstab 5 zur Kontaktgabe gebracht, so bewirkt das Auflaufen der Kontaktbrücken 2, 3 auf den Kontaktstab 5, was ja mittels der beiden Auflaufflächen 10, 11 erfolgt, zunächst ein Abwälzen der beiden aneinanderliegenden gewölbten Flächen (Fig. 1), wodurch sich die Auflauföffnung für den Kontaktstab 5 an der V-förmigen Einformung der beiden Kontaktbrücken 2, 3 öffnet, ohne daß die beiden Kontaktbrücken auf die lichte Weite, die durch den Kontaktstab 5 vorgegeben-ist, auseinandergedrückt werden müssen. Sobald die Kontaktbrücken 2, 3 ihre Mittellage zum Kontaktstab 5 erreicht haben, erfolgt eine Eigenjustierung unter Bildung von je zwei Kontaktstellen 8 bzw. 9 am Kontaktstab 5 (vergleiche Fig. 5). Das gegenseitige Abwälzen der beiden Kontaktbrücken 2, 3 aneinander wird hierbei erleichtert, dadurch, daß die beiden Kontaktstellen 6 bzw. 7 am Kontaktring 1 ebenfalls als erhabene Anprägungen ausgebildet sind, wobei diese Anprägungen in Längsrichtung der Kontaktbrücke hintereinander liegen. Die aus Flachmaterial bestehende Kontaktbrücke 2, 3 ist so gestaltet, daß sie ohne weiteres in einem Arbeitsgang als Prägeteil herstellbar ist.If, as can be seen in particular from FIG. 1, the two contact bridges 2, 3 are brought into contact by pivoting laterally with the contact rod 5, the contact bridges 2, 3 run onto the contact rod 5, which is done by means of the two contact surfaces 10, 11 , first rolling the two curved surfaces lying against one another (FIG. 1), as a result of which the run-on opening for the contact rod 5 on the V-shaped indentation of the two contact bridges 2, 3 opens without that the two contact bridges must be pressed apart to the clear width, which is predetermined by the contact rod 5. As soon as the contact bridges 2, 3 have reached their central position with respect to the contact rod 5, self-adjustment takes place with the formation of two contact points 8 and 9 on the contact rod 5 (see FIG. 5). The mutual rolling of the two contact bridges 2, 3 against each other is facilitated here in that the two contact points 6 and 7 on the contact ring 1 are also formed as raised impressions, these impressions lying one behind the other in the longitudinal direction of the contact bridge. The contact bridge 2, 3 made of flat material is designed in such a way that it can be produced as an embossed part in one operation.
