Abstract

In the case of the installation, compartments (6, 7, 8) are provided which are separated from one another by means of walls (4, 5) and are jointly monitored by a gas monitoring device (11). In the case of a gas monitoring device (11) which is connected to pipelines, in order to prevent feedback effects from one compartment acting on the others via these pipelines, the individual compartments (6, 7, 8) are connected to the gas monitoring device (11) via a pipeline trunk line (9, 10) and in each case one non-return valve (13) is arranged in branch lines (12) from the trunk line (9, 10) to the compartments (6, 7, 8) such that the compartments (6, 7, 8) are hermetically isolated from one another via the trunk line (9, 10). In consequence, electrical defects, such as gas and solid material breakdowns in the switching installation resulting from gas impurities, are largely prevented. <IMAGE>

Description

Metallgekapselte druckgasisolierte HochspannungsschaltanlageMetal-enclosed, compressed gas-insulated high-voltage switchgear

Die Erfindung bezieht sich auf eine metallgekapselte, druckgasisolierte und in Schotträume aufgeteilte Hochspannungsschaltanlage, mit einer Gasüberwachungseinrichtung.The invention relates to a metal-enclosed, pressurized gas-insulated and high-voltage switchgear, divided into compartments, with a gas monitoring device.

Es sind metallgekapselte, durckgasisolierte Hochspannungsschaltanlagen bekanntgeworden, deren Schotträume über Rohrleitungen hintereinandergeschaltet sind. Dadurch ist es mögsich, daß sich elektrische Durchschläge im Isoliergas bzw.They are metal-enclosed, pressurized gas-insulated high-voltage switchgear became known whose compartments are connected in series via pipelines. This makes it possible for electrical breakdowns to occur in the insulating gas or

in der Feststoffisolierung auch auf Nachbarräume auswirken.in the solid insulation also affect neighboring rooms.

So können bei dreiphasig gekapselten Schaltanlagen die durch den Lichtbogen erzeugten Zersetzungsprodukte weitere Schotträume verunreinigen. Bei einphasig gekapselten Schaltanlagen, wird die auf der Einzelkapselung beruhende Kurzschlußsicherheit der Phasenleiter untereinander stark vermindert, indem bei einem Erdschluß eines Leiters, heiße Lichtbogengase durch die Rohrleitungen auch in die Kapseln der anderen Leiter getrieben werden, was zum Erdschluß eines weiteren Leiters und schließlich zu einem dreipoligen Kurzschluß führen kann, was eine empfindliche Störung des Anlagenbetriebes zur Folge hat.In three-phase encapsulated switchgear, for example, the Decomposition products generated contaminate further compartments. With single-phase encapsulated Switchgear, the short-circuit protection based on the individual encapsulation is the Phase conductors are greatly reduced among each other, in that in the event of an earth fault in one conductor, hot arc gases through the pipes also into the capsules of the other conductors be driven, which leads to the ground fault of another conductor and finally to a three-pole short-circuit, which can cause a sensitive disruption of the system operation has the consequence.

Der Erfindung liegt die Aufgabe zugrunde, die einzelnen Schotträume der Hochspannungsschaltanlage so mit der Gasüberwachungseinrichtung zu verbinden, daß Rückwirkungen über die Rohrleitungen von einem Schottraum auf einen anderen, vermieden sind.The invention is based on the object, the individual Bulkheads to connect the high-voltage switchgear to the gas monitoring device in such a way that that repercussions through the pipelines from one compartment to another, are avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die einzelnen Schotträume über eine Rohrleitungssammelschiene an die Uberwachungseinrichtung angeschlossen sind, und daß in den Abzweigleitungen von der Rohrleitungssammelschiene zu den Schotträumen jeweils ein Rückschlagventil so angeordnet ist, daß eine Verbindung unter den Schotträumenüber die Rohrleitungssammelschiene verhindert ist.This object is achieved according to the invention in that the individual Compartments connected to the monitoring device via a pipeline busbar are, and that in the branch lines from the pipeline busbar to the compartments in each case a check valve is arranged so that a connection under the bulkheads over the pipeline busbar is prevented.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß elektrische Fehler wie Gas- bzw. Feststoffdurchschläge in der Schaltanlage aufgrund von Gasverunreinigungen weitgehend vermieden werden, wodurch die Revisionszeiten der Schaltanlage auf ein Mindestmaß eingeschränkt sind. Hierzu trägt weiterhin bei, daß die Schotträume aufgrund ihrer Parallelschaltung an die Gasüberwachungseinrichtung einzeln leicht zugänglich sind, so daß sich eventuelle Revisionsarbeiten. einfach und schnell durchführen lassen.The advantages achieved with the invention are in particular: that electrical faults such as gas or solids breakdowns in the switchgear are due to of gas contamination can be largely avoided, reducing the revision times the switchgear are restricted to a minimum. This also contributes to that the compartments due to their parallel connection to the gas monitoring device are individually easily accessible, so that any revision work. simple and have it carried out quickly.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.

Die einzige Figur zeigt in schematischer Darstellung ein einphasig gekapseltes Schaltfeld 1 mit einer dreiphasig gekapselten Doppelsammelschiene 2.The single figure shows a single phase in a schematic representation Encapsulated switchgear panel 1 with a three-phase encapsulated double busbar 2.

Die Kapseln 3 pro Phasenleiter im Schaltfeld sind über Trennwände 4,5 in einzelne Schotträume 6,7,8 aufgeteilt, die mit Hilfe einer Rohrleitungssammelschiene 9,10 parallel an eine Gasüberwachungseinrichtung angeschlossen sind, welche durch ein Kontaktmanometer 11 angedeutet ist. In den von der Rohrleitungssammelschiene 10 zu den Schotträumen 6,7,8 führenden Abzweigleitungen 12, sind in von der Kapsel abgehender Richtung gesperrte Rückschlagventile 13 angeordnet, so daß eine Verbindung der Schotträume untereinander vermieden ist.The 3 capsules per phase conductor in the switchgear panel are over partition walls 4.5 divided into individual compartments 6,7,8 with the help of a pipeline busbar 9.10 parallel are connected to a gas monitoring device, which is indicated by a contact manometer 11. In the from the pipeline busbar 10 branch lines 12 leading to the bulkheads 6,7,8 are in from the capsule outgoing direction blocked check valves 13 arranged so that a connection the bulkheads between each other is avoided.

Dabei sind die Rückschlagventile 13 über eine doppeltwirkende Rückschlagklappe 14 mit dem Schottraum verbunden, was ein einfaches Auswechseln der Rückschlagventile ermöglicht, indem beim Lösen derselben die Rückschlagklappe 14 abgehend sofort sperrt, so daß ein Ausströmen von Isoliergas nicht möglich ist. Die gleiche Maßnahme ist auch bei dem Kontaktmanometer 11, sowie bei den Kontaktmanometern15, 16 an der Doppelsammelschiene 2 vorgesehen. Weiterhin sind die Schotträume wie auch die Doppelsammelschiene mit sogenannten Vakuumkupplungen 17 versehen. Das sind doppeltwirkende Rückschlagklappen mit einem Betätigungselement über die auf einfache Art und Weise z.B. ein Manometer zur über prüfung des Gasdruckes oder eine Gasflasche zum Nachfüllen von Isoliergas angeschlossen werden kann.The check valves 13 are via a double-acting check valve 14 connected to the bulkhead, which makes it easy to replace the check valves made possible by the non-return valve 14 immediately locks when it is released, so that an outflow of insulating gas is not possible. The same measure is also with the contact manometer 11, as well as with the contact manometers 15, 16 on the double busbar 2 provided. Furthermore, the compartments as well as the double busbar are included so-called vacuum couplings 17 are provided. These are double-acting check valves with an actuating element via a manometer, for example, in a simple manner to check the gas pressure or a gas cylinder to refill insulating gas can be connected.
