"Isolierstützer für druckgasisolierte, metallgekapselte Hochspannungs-Schaltanlagen""Insulating support for pressurized gas-insulated, metal-encapsulated High voltage switchgear "

Die Erfindung bezieht sich auf einen Isolierstütser für druckgasisolierte, metallgekapselte Hochspannungs-Schaltanlagen, der zugleich als Schottungselement zwischen hintereinanderliegenden, druckgasgefüllten Einzelabteilen für die Aufnahme von Bauteilen der Schaltanlage dient.The invention relates to an insulating support for pressurized gas-insulated, metal-enclosed high-voltage switchgear, at the same time as a partition element between one behind the other, pressurized gas-filled individual compartments is used to accommodate components of the switchgear.

Es ist bereits bekannt, solche Isolierstützer in ihrer Festigkeit so zu bemessen, daß ihr Berstdruck etwa ein Drittel desjenigen der sie umgebenden Metallkapselung ist (Schweizer PS 464· 321). Durch eine derartige Ausbildung der Isolatoren soll verhindert werden, daß bei einem in der Metallkapselung entstehenden hohen Überdruck, z.B. durch einen Lichtbogen bei einem Kurzschluß, die Metallkapselung beschädigt wird und größere Störungen auftreten. Das Bersten der Isolatoren kann aber dazuIt is already known to dimension such insulating supports in terms of their strength so that their bursting pressure is approximately one Third of that of the surrounding metal encapsulation (Swiss PS 464 · 321). By training like this of the insulators should be prevented from occurring in the event of a high overpressure in the metal encapsulation, e.g. by an electric arc in the event of a short circuit, the metal enclosure is damaged and major faults appear. But the bursting of the insulators can cause it

führen, daß die von ihnen getragenen Bauteile der Schaltanlage nicht mehr ordnungsgemäß abgestützt werden und auch weitere Isolatoren durch die mit hoher Geschwindigkeit fortgeschleuderten Bruchstücke der Isolatoren beschädigt werden.lead to the fact that the components of the switchgear carried by them are no longer properly supported and also other insulators are damaged by the fragments of the insulators being thrown away at high speed will.

Zur Vermeidung einer solchen Gefahr sieht die Erfindung vor, daß der Isolator an einer oder mehreren Stellen im Querschnitt so geschwächt ist, daß bei überhöhten · Drücken diese Stellen bersten, die Tragfähigkeit des Stützers aber erhalten bleibt. Die Entlastung eines Abschnitts der Hochspannungs-Schaltanlage bei überhöhtem Druck durch Verringerung dieses Druckes infolge Freigabe · eines größeren Raumes für das unter erhöhten Druck gesetzte gasförmige Isoliermittel erfolgt also in der bekannten Weise. Dabei ist aber nicht zu befürchten, daß die an den Berststellen herausgeschleuderten kleineren Bruchstücke, des Isolators eine solche Wucht haben, daß auch benachbarte Isolatoren zerstört werden. Ferner ergibt sich der Vorteil, daß der teilweise geborstene Isolator nach wie vor seine Eigenschaft als Tragstützer behält, so daß keine Berührung der elektrisch leitenden Teile mit der Metallkapselung erfolgen kann.To avoid such a risk, the invention provides that the insulator at one or more points is so weakened in cross-section that if the pressure is too high, these points burst, the load-bearing capacity of the Stützers is retained. The relief of a section of the high-voltage switchgear in the event of excessive pressure Pressure by reducing this pressure as a result of releasing a larger space for the pressurized gaseous insulating means is therefore carried out in the known manner. But there is no reason to fear that the Smaller fragments ejected from bursting points, the insulator being so powerful that neighboring ones too Isolators are destroyed. There is also the advantage that the partially ruptured insulator still has its place Retains property as a support, so that no contact of the electrically conductive parts with the metal enclosure can be done.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung an einem Isolierstützer in Konusform, der aber auch als Scheibenstützer ausgebildet sein könnte.The drawing shows an embodiment of the invention on an insulating support in a cone shape, but also as a Disc supports could be formed.

Der Isolierstützer 1 mit den querschnittsgeschwächten Stellen 2 gehört zu einem Trennschalter, der in dem druckgasgefüllten Gehäuse 3 untergebracht ist. Das von einem Motor 4 angetriebene bewegliche Schaltstück 5 ist in einem Metallgehäuse 6 gelagert, das von den Vollisolierstützern 7 und 8 getragen wird. Das feste Schaltstück 9 dieses Trennschalters wird von dem Isolator 1 getragen, derThe insulating support 1 with the cross-sectionally weakened points 2 belongs to a circuit breaker, which is in the pressurized gas-filled Housing 3 is housed. The movable contact 5 driven by a motor 4 is in one Metal housing 6 supported, which is supported by the fully insulating supports 7 and 8. The fixed contact piece 9 this Circuit breaker is carried by the isolator 1, the

zwischen dem Metallgehäuse 3 !JJ3d einem weiteren Metallgehäuse 10 angeordnet ist, das einen Sammelschienenleiter aufnehmen kann. Bei einem überhöhten Druck im Raum 11 wird durch Herausbrechen der scheibenförmigen Stellen 2 im Isolierstützer 1 dieser Druck stark herabgesetzt, da das gasförmige Isoliermittel nach dem benachbarten Raum im Gehäuse 10 ausweichen kann. Dabei behält der Isolierstützer seine mechanische Festigkeit als Träger des festen Schaltstückes 9· between the metal housing 3 ! JJ3d is arranged in a further metal housing 10 which can accommodate a busbar conductor. If the pressure in the space 11 is too high, this pressure is greatly reduced by breaking out the disk-shaped points 2 in the insulating support 1, since the gaseous insulating agent can escape to the adjacent space in the housing 10. The insulating support retains its mechanical strength as a carrier for the fixed contact piece 9

Die querschnittsgeschwächten Stellen 2 können :.ich aus einem anderen Material als dem des Stützers bestehen, das dann in geeigneter Weise, z.B. durch Eingießen, mit letzterem fest verbunden wird.The cross-sectional weakened points 2 can: .ich aus consist of a different material than that of the support, which is then mixed in a suitable manner, e.g. by casting the latter is firmly connected.
