Bei bekannten Drehumstellern der Rohrtype werden die feststehenden Kontaktstücke an einem Isolierstoffzylinder in senkrechten Querschnittebenen angeordnet. Eine in der Zylinderachse liegende Welle trägt Kontaktbrücken, die den einzelnen Kontaktebenen zugeordnet sind und jeweils zwei Kontaktstücke einer Ebene miteinander verbinden.In known rotary converters of the tube type, the fixed contact pieces are attached to an insulating cylinder arranged in vertical cross-sectional planes. A shaft lying in the cylinder axis carries Contact bridges that are assigned to the individual contact levels and two contact pieces each Connect levels with each other.

Die Bestückung der Welle und des Zylinders mit den Kontaktelementen erfolgt vor dem Zusammenbau, d. h. vor dem Einfahren der Welle in den Zylinder. Bei der konstruktiven Ausbildung der Kontaktelemente muß daher darauf geachtet werden, daß zur axialen Bewegung der bestückten Welle genügend Spielraum bleibt. So gelangte man zu einer mehr oder weniger U-förmigen Ausbildung der Kontaktbrücken. Beim Einfahren der Welle können dann die feststehenden Kontaktstücke in den U-Bogen der Kontaktbrücke hineinragen.The shaft and the cylinder are fitted with the contact elements before assembly, d. H. before the shaft is retracted into the cylinder. In the design of the contact elements care must therefore be taken to ensure that there is sufficient axial movement of the equipped shaft There is still room for maneuver. This resulted in a more or less U-shaped design of the contact bridges. When the shaft retracts, the fixed contact pieces can then be placed in the U-bend of the contact bridge protrude.

Die wärmeabgebende Oberfläche der Kontaktbrükken ist dabei jedoch verhältnismäßig gering, und die meist aus Hartpapier bestehende Umstellerwelle mußte zur Aufnahme der Kontaktbrücken und der zugehörigen Federelemente stark angeschnitten werden. Da außerdem das Innere der bekannten Drehumsteller nach Einfahren der Welle nicht mehr zugänglich ist, ergeben sich Schwierigkeiten bei der Fertigungskontrolle und bei Überholungsprüfungen.The heat-emitting surface of the contact bridges is, however, relatively small, and the mostly made of hard paper changeover shaft had to accommodate the contact bridges and the associated spring elements are severely cut. There is also the inside of the well-known rotary switch is no longer accessible after the shaft has been retracted, difficulties arise during production control and for overhaul inspections.

Erfindungsgemäß wird ein rohrförmiger Drehumsteller vorgeschlagen, der dadurch gekennzeichnet ist, daß der die Festkontakte tragende Isolierstoffzylinder in Längsrichtung in Schalen geteilt ist. Die Merkmale des Rohrumstellers, wie z. B. große mechanische Stabilität bei einfacher Herstellung, bleiben dabei voll erhalten. Bei der Montage werden die beiden Schalen um die Welle gelegt und auf geeignete Weise befestigt. Zwischen den Schalen können Ölströmungs-Schlitze frei bleiben.According to the invention, a tubular rotary diverter is proposed which is characterized in that that the insulating material cylinder carrying the fixed contacts is divided into shells in the longitudinal direction. The characteristics of the pipe diverter, such as B. great mechanical stability with simple production, remain full obtain. During assembly, the two shells are placed around the shaft and fastened in a suitable manner. Oil flow slots can remain free between the shells.

Um die Kontaktanordnung vor gefährlichen Schmutzablagerungen zu schützen, ist es ferner vorteilhaft, das Rohrinnere an den Ölströmungs-Schlitzen durch Siebgitter gegen das Eindringen von Schmutzteilchen und Fremdkörpern abzudecken.In order to protect the contact arrangement from dangerous dirt deposits, it is also advantageous to the inside of the pipe at the oil flow slots through sieve grids against the ingress of dirt particles and to cover foreign bodies.

An Hand der Fig. 1 und 2 sollen im folgenden zwei Ausführungsbeispiele der Erfindung mit unterschiedlichen Kontaktanordnungen näher erläutert werden. Die Zeichnungen stellen jeweils Querschnitte durch die Rohrumsteller dar. Teile mit gleichen Bezeichnungen sind mit gleichen Bezugsziffern bezeichnet. With reference to FIGS. 1 and 2, two exemplary embodiments of the invention with different ones are to be described below Contact arrangements are explained in more detail. The drawings represent cross-sections by the pipe diverter. Parts with the same designations are denoted by the same reference numerals.

bezeichnet, deren die Schalen 1 und 3 durchsetzende, rückwärtige Teile mit den zugehörigen Leitungsanschlüssen nicht dargestellt sind. Die angeschnittene rohrförmige Umstellerwelle 6 trägt die Kontaktbrükken 9. Die Halterung erfolgt durch zwei Bolzen 7, welche von oben und unten in tiegelförmigen Höhlungen der Kontaktbrücken 9 eingreifen und selbst an der Einlage 5 befestigt sind. Eine Druckfeder liegt bei 10 auf der Kontaktbrücke 9 auf. Zwischen den beiden Schalen 1 und 3 bleiben Ölströmungs-Schlitze 2 und 8 frei.denotes, the shells 1 and 3 penetrating, rear parts with the associated line connections are not shown. The cut tubular diverter shaft 6 carries the contact bridges 9. It is held by two bolts 7, which are inserted into crucible-shaped cavities from above and below engage the contact bridges 9 and are themselves attached to the insert 5. A compression spring lies at 10 on the contact bridge 9. Oil flow slots 2 remain between the two shells 1 and 3 and 8 free.

Die Erfindung eröffnet somit die Möglichkeit, die Kontaktbrücken flächenmäßig größer auszulegen, was wiederum eine spezifisch höhere Strombelastbarkeit der Kontaktstellen ergibt. Die Druckfeder-Konstruktion kann radial weiter nach außen verlegt werden, wodurch die Welle weniger angeschnitten zu werden braucht und damit mechanisch stabiler wird.The invention thus opens up the possibility of making the contact bridges larger in area, which in turn results in a specifically higher current carrying capacity of the contact points. The compression spring construction can be moved radially further outwards, which means that the shaft has to be cut less needs and thus becomes mechanically more stable.

Der Rohrumsteller nach F i g. 2 besitzt acht feststehende Kontaktstücke 4. Die Kontaktbrücke 9 ist in einzelne flache Kontaktleisten 11 aufgeteilt, die über Halterungen 12 aus Isolierstoff an der Welle 6 angebracht sind. Diese Kontaktanordnung, die sich für höchste Stromstärken besonders gut eignet, kann bei Rohrumstellern erst durch die Erfindung angewendet werden.The pipe diverter according to FIG. 2 has eight fixed contact pieces 4. The contact bridge 9 is in divided individual flat contact strips 11, which are attached to the shaft 6 via brackets 12 made of insulating material are. This contact arrangement, which is particularly suitable for the highest currents, can be used for Pipe changers are only used by the invention.

Beide Ausführungsbeispiele lassen erkennen, daß die Montage sowie auch elektrische und mechanische Prüfvorgänge wesentlich erleichtert werden. Durch die Schlitze entlang des Isolierstoffzylinders hat kühlendes Öl wesentlich besseren Zutritt zu den Kontaktelementen. Both embodiments show that the assembly as well as electrical and mechanical Test processes are made much easier. Through the slots along the insulating material cylinder cooling oil much better access to the contact elements.
