Abstract

The converter has a barrel-shaped housing (11) that can be mounted on a frame (19). The housing has a dome (15) as a lid in which are located three high voltage insulators for overhead cables in a row or in a triangle. Inside the housing are three voltage converter units (13). The housing and its lead-ins are designed for gas insulation. The converter units work on an optical or capacitative principle.

Description

Die Erfindung bezieht sich auf eine Spannungswandleranordnung für Mittel- oder Hochspannungssysteme und für Freiluftaufstellung.The invention relates to a voltage converter arrangement for medium or High voltage systems and for outdoor installation.

Aus der Veröffentlichung SESWG/I 4007 T, 1994-03, "Spannungswandler Typ EMFC" der Firma ABB Switchgear AB, Ludvika, Schweden, sind einphasige indukti­ ve Freiluftspannungswandler bekannt. Die induktiven Wandler sind jeweils in einem Kessel angeordnet. Die Wandlerwicklungen sind mit einer Öl-Papier-Isolierung ver­ sehen und die Kessel sind mit ölgetränktem Quarzsand gefüllt. Für die üblichen Drehstromsysteme sind drei Einzelgeräte notwendig. Diese bestehen jeweils aus einem Kessel mit Wandler, einem Hochspannungsanschluß mit äußerem Isolator, einer Verbindung zum Spannungswandler sowie einem Klemmenkasten für sekun­ därseitige Anschlüsse.From the publication SESWG / I 4007 T, 1994-03, "Voltage converter type EMFC "from ABB Switchgear AB, Ludvika, Sweden, are single-phase inductors ve known outdoor voltage converter. The inductive converters are each in one Boiler arranged. The converter windings are equipped with oil-paper insulation see and the kettles are filled with oil-soaked quartz sand. For the usual Three-phase systems require three individual devices. These consist of a boiler with a converter, a high-voltage connection with an external insulator, a connection to the voltage converter and a terminal box for sekun intestinal connections.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, für ein Drehstromsy­ stem eine Freiluftspannungswandleranordnung anzugeben, die kostengünstiger rea­ lisierbar ist.Based on this, the object of the invention is for a three-phase system stem to specify an outdoor voltage converter arrangement that rea cheaper is lisizable.

Diese Aufgabe wird bei einer Freiluftspannungswandleranordnung nach dem Ober­ begriff des Anspruchs 1 durch dessen kennzeichnende Merkmale gelöst.This task is performed in an outdoor voltage converter arrangement according to the upper Concept of claim 1 solved by its characterizing features.

Die vorgeschlagene Anordnung von drei Spannungswandlern in einem gemeinsa­ men Gehäuse führt zu einer kompakten Einheit, die fabrikfertig montiert und geprüft zur Baustelle transportiert werden kann. Der Montage- und Inbetriebnahmeaufwand läßt sich dadurch erheblich reduzieren. Gemäß einer vorteilhaften Ausgestaltung der Erfindung wird vorgeschlagen statt induktiver Wandler unkonventionelle optische oder kapazitive Wandler einzusetzen.The proposed arrangement of three voltage converters in a common men housing leads to a compact unit that is assembled and tested ready for use in the factory  can be transported to the construction site. The assembly and commissioning effort can be significantly reduced. According to an advantageous embodiment of the Invention is proposed instead of inductive optical converters instead of inductive ones or use capacitive converters.

Eine weitere Beschreibung der Erfindung erfolgt nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels.A further description of the invention is given below with the aid of a Drawing shown embodiment.

Fig. 1 zeigt eine Spannungswandleranordnung mit einem topfförmigen Gehäuse 11, in das drei Spannungswandler 13 eingesetzt sind. Der Deckel des Gehäuses 11 ist als kuppelförmiger Dom 15 ausgeführt. Auf Durchführungen 12 des Doms 15 sind Freileitungsisolatoren 17 aufgesetzt. Innerhalb des Gehäuses 11 und des Doms 15 befinden sich elektrische Verbindungen 14 zwischen oben liegenden ersten An­ schlüssen der Wandler 13 und den durch die Isolatoren 17 geführten Phasenleitern 10. Unten liegende zweite Anschlüsse der Wandler 13 sind geerdet. Fig. 1 shows a voltage transformer assembly comprising a cup-shaped housing 11, are inserted into the three voltage converter 13. The cover of the housing 11 is designed as a dome-shaped dome 15 . Overhead line insulators 17 are placed on bushings 12 of the dome 15 . Within the housing 11 and the dome 15 there are electrical connections 14 between the first connections at the top of the converter 13 and the phase conductors 10 guided through the insulators 17 . Second connections of the transducers 13 located at the bottom are grounded.

Durch die Anordnung des kuppelförmigen Doms 15 mit seinen gegenüber der Senk­ rechten in unterschiedlichen Winkeln angeordneten Durchführungen 12 ist erreicht, daß trotz der kompakten Bauweise die freiluftseitigen Hochspannungsanschlüsse 10 die erforderlichen Abstände aufweisen. Das gilt sowohl für eine Anordnung der auf die Durchführung 12 aufgesetzten Freileitungsisolatoren 17 in einer Reihe oder im Dreieck. Durch Anordnung des Gehäuses 11 auf einem Gerüst 19 wird die Einhal­ tung der vorgeschriebenen Isolierungsabständen gegenüber Erde erreicht. Mit 18 ist ein Schutzgasanschluß für Schwefelhexafluorid bezeichnet.The arrangement of the dome-shaped dome 15 with its bushings 12 arranged at different angles with respect to the countersink means that, despite the compact design, the open-air high-voltage connections 10 have the required distances. This applies both to an arrangement of the overhead line insulators 17 placed on the bushing 12 in a row or in a triangle. By arranging the housing 11 on a scaffold 19 , the compliance with the prescribed insulation distances from earth is achieved. With 18 a protective gas connection for sulfur hexafluoride is designated.

Es wird außerdem vorgeschlagen, anstelle induktiver Spannungswandler unkonven­ tionelle optische oder kapazitive Wandler einzusetzen, die einen verringerten Platz­ bedarf haben, wodurch - in Verbindung mit der Schutzgasisolierung - das Gehäuse 11 besonders klein und damit auch kostengünstig ausgeführt werden kann.It is also proposed to use unconven tional optical or capacitive converters instead of inductive voltage converters, which have a reduced space, so that - in connection with the protective gas insulation - the housing 11 can be made particularly small and thus inexpensive.
