Abstract

To contain the three voltage transformers (1) within the general circular profile of the bus duct (6) local protrusions are provided (7) in which the cores and windings of each transformer are in part accommodated. Being local the duct section can be terminated with standard flanges thus making coupling to, and sealing with, the rest of the gas filled system a normal operation. The size of the protrusions is also chosen to allow offset positioning of the transformers during assembly so that all three can be entered through the standard circular opening. With this design a three-phase voltage transformer is accommodated within the general system and the need for specially adapted single phase units eliminated.

Description

"Dreiphasig gekapselte, druckgasisolierte Hochspannungsschalt-"Three-phase encapsulated, pressurized gas-insulated high-voltage switching

anlage" Die Erfindung bezieht sich auf eine dreiphasig gekapselte, drucks gasisolierte Hochspannungsschaltanlage mit einem jeweils pro Phase zugeordneten Spannungswandler.system "The invention relates to a three-phase encapsulated, pressure gas-insulated high-voltage switchgear with one assigned to each phase Voltage converter.

Wegen des zunehmenden Energiebedarfs in Industriegebieten und Großstädten muß die elektrische Energie über Hochspannung bis in die Verbraucherzone geleitet werden. Dies -hat bei der Energieverteilung zur vermehrten Anwendung von metallgekapselten, SF6-isolierten Schaltanlagen geführt, die gegenüber herkömmlichen Schaltanlagen nur einen Raumbedarf von etwa 10 % haben.Because of the increasing demand for energy in industrial areas and large cities the electrical energy must be conducted via high voltage to the consumer zone will. In the case of energy distribution, this has led to the increased use of metal-encapsulated, SF6-insulated switchgear led, compared to conventional switchgear only have a space requirement of about 10%.

Da man bisher die Geräte einphasig und wenn überhaupt nur die Sammelschiene dreiphasig gekapselt hat, sind Spannungswandler auch nur für einphasig gekapselte Schaltanlagen bekanntgewoi-den Neuerdings ist man aber bestrebt, die gesamte Hochspannungsschaltanlage dreiphasig zu kapseln.Since so far the devices have been single-phase and, if at all, only the busbar three-phase encapsulated, voltage transformers are also only for single-phase encapsulated Switchgear well-known Recently, however, efforts have been made to install the entire high-voltage switchgear three-phase to encapsulate.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Kapselung für einen Spannungswandler in einer dreiphasig gekapselten Schaltanlage zu schaffen.The invention is therefore based on the object of an encapsulation for to create a voltage converter in a three-phase enclosed switchgear.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Spannungswandler in einer gemeinsamen Kapsel sternförmig angeordnet sind, wobei zur Verringerung des Umfangs der Kapsel die Spannungswandler teilweise über das Kreisprofil der Kapsel hinr ausragen, und daß die Kapsel an ihrem Umfang entspreçhende Ausformungen aufweist, in welche die Spannungswandler hineinragen, während an den beiden Enden der Kapsel die Flansche kreisrund gehalten sind.This object is achieved according to the invention in that the voltage converter are arranged in a star shape in a common capsule, whereby to reduce the circumference of the capsule, the voltage converter partially over the circular profile of the capsule protrude out, and that the capsule on its circumference corresponding formations having, into which the voltage converters protrude, while at the two ends of the capsule the flanges are circular.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Kapselung der äußeren Kontur der Spannungswandleranordnung angepaßt ist, wodurch sich der Umfang der Kapselung verringert, was zu einer entsprechenden Materialersparnis führt.The advantages achieved with the invention are in particular: that the encapsulation is adapted to the outer contour of the voltage transformer arrangement, whereby the extent of the encapsulation is reduced, which leads to a corresponding saving in material leads.

Ein Ausführungsbeispiel ist in der Zeichnung schematisch dargestellt und wird im folgenden näher beschrieben. Die Fig. 1 zeigt einen Querachnitt durch einen dreiphasig gekapselten Spannungswandler. Drei jeweils einer Phase zugeordnete Spannungswandler1 sind sternförmig im Winkel von 120° zueinander angeordnet, so daß jeder Wandler über eine starre Steckverbindung mit dem jeweiligen Phasenleiter der Anlage verbunden werden kann. Jeder Wandler 1 besteht aus einem Aktivteil 4 sowie demontierbaren Schirmelektroden 5 und einem Eisenkern 2, wobei auf einem Schere kel des Eisenkernes 2 eine Sekundärwicklung und eine Primärwicklung konzentrisch aufgebracht sind und die äußere Wicklung eine Isolierung aufweist. Die Wandler 1 sind von einer gemeinsamen Kapselung 6 umgeben und sc angeordnet, daß sie mit dem freien Schenkel 3 des Eisenkerns 2 iiber das Kreisprofil der Kapselung 6 hinausragen, durch Ausformungen 7 am Umfang der Kapselung umfaßt und somit in die Kapselung mit einbezogen sind.An exemplary embodiment is shown schematically in the drawing and is described in more detail below. Fig. 1 shows a cross section through a three-phase encapsulated voltage converter. Three each assigned to a phase Voltage transformers1 are arranged in a star shape at an angle of 120 ° to one another, see above that each converter has a rigid plug connection with the respective phase conductor the system can be connected. Each converter 1 consists of an active part 4 and removable shield electrodes 5 and an iron core 2, with scissors on kel of the iron core 2 a secondary winding and a primary winding concentric are applied and the outer winding has insulation. The converters 1 are surrounded by a common encapsulation 6 and arranged sc that they with the free legs 3 of the iron core 2 protrude beyond the circular profile of the enclosure 6, encompassed by formations 7 on the circumference of the encapsulation and thus in the encapsulation with are included.

Die Kapselung ist an ihrer einen Stirnseite mit einem Deckel verschlossen und über ihre andere Stirnseite an die Kapselung der Schaltanlage angeflanscht.The encapsulation is closed with a cover on one of its front sides and flanged to the enclosure of the switchgear via its other end face.

Da der Flanschinnendurchmesser der Montageöffnung der Kapsel kleiner ist, als der umschriebene Kreis der Wandler in Einbaulage, werden bei der Montage die beiden zuerst in die Kapsel eingesetzten Wandler nach Fig. 2 etwas zur Seite bewegt, um auch den dritten Wandler einsetzen zu können. Hiernach werden dieselben in ihrer endgültigen Position nach Fig. 1, befestigt Durch diese Naßnahine behalten die beiden Flansche ihre Kreisform, trotz des nichtkreisförmigen Querschnitts der Kapsel, infolge der Auslormungen 7 an ihren Umfang. Damit ist eine einfache Bearbeitung und Abdichtung der Flansche gewährleistet.Because the flange inside diameter of the assembly opening of the capsule is smaller is, as the circumscribed circle of the converter in the installation position, are during assembly the two transducers first inserted into the capsule according to FIG. 2 a little to the side moved to to be able to use the third converter as well. After that are the same in their final position according to Fig. 1, fastened by this When wet, the two flanges retain their circular shape, despite the non-circular shape Cross-section of the capsule, due to the recesses 7 on its circumference. So that's a easy processing and sealing of the flanges guaranteed.
