Abstract

The switching device for medium voltages, using insulating gas or liquid, has a fuse support (2) immediately connected to the device (1) which is filled with the gas, or liquid. The connection (2b) for the support is inside the insulating sleeve (2a) and is in contact with atmosphere. Between this insulating sleeve and the outside cap (7) is a compact electrical seal (3), which takes up both the movement and force of the contact pin (4) which is supported at the centre of the cap. The sleeve around the support has side outlets (5), each fitted with a cap which is forced off by any gas pressure generated.

Description

Bezeichnung: Sicherungsträger für gas-oderDesignation: fuse holder for gas or

flüssigkeitsisolierte Mittelspannungsschaltanlagen Die Erfindung betrifft einen Sicherungsträger für gas-oder flüssigkeitsisolierte Mittelspannungsschaltanlagen, zur Aufnahme von z.B. Hochleistungssicherungen. liquid-insulated medium-voltage switchgear the The invention relates to a fuse carrier for gas- or liquid-insulated medium-voltage switchgear, to accommodate e.g. high-performance fuses.

Der Erfindung liegt die Aufgabe zugrunde, den Sicherungsträger so zu gestalten, daß die darin eingesetzten Sicherungen keinen äußeren Einflüssen, insbesondere Verschmutzung ausgesetzt sind und somit eine Wartung der Sicherungen in Form einer Reinigung entfällt.The invention is based on the object of the fuse carrier so to be designed so that the fuses used do not have any external influences, in particular are exposed to contamination and thus maintenance of the fuses in the form of cleaning is not necessary.

Die in den Isolierkalotten gekapselten Sicherungen können höher belastet werden, als die gleiche Anordnung in Luft, da bei einem Isolier¾/aswie z.B. SF6, die Wärmeübergangswerte zwischen den Kalotten und dem umgebenden Medium denen des Überganges auf die Luft überlegen sind.The fuses encapsulated in the insulating caps can be subjected to higher loads as the same arrangement in air, because with an insulating / as such as SF6, the heat transfer values between the domes and the surrounding medium are those of the Transitions to the air are superior.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Sicherungsträger an der mit Isoliergas oder einer isolierenden Flüssigkeit gefüllten Schalteinheit unmittelbar sowohl mechanisch als auch mit dem Isoliermedium angekuppelt ist.This object is achieved according to the invention in that the fuse carrier on the switching unit filled with insulating gas or an insulating liquid is directly coupled both mechanically and with the insulating medium.

Eine Ausführungsbeispiel der vorliegenden Erfindung wird anhand der Zeichnungen näher erläutert.An embodiment of the present invention is based on the Drawings explained in more detail.

Darin zeigen: Fig. 1 ein Ausführungsbeispiel des erfindungs-Sicherungsträgers, wobei die Schalteinheit im oberen Teil im Schnitt dargestellt ist, um den Sicherungsträger sichtbar zu machen und Fig.2 die Seitenansicht von Fig. 1, hier ist der mittlere Teil der Schalteinheit im Schnitt dargestellt,um ein Entlastungskanal sichtbar zu machen.1 shows an exemplary embodiment of the fuse carrier according to the invention, wherein the switching unit is shown in the upper part in section to the fuse carrier to make visible and Fig.2 the side view of Fig. 1, here is the middle one Part of the switching unit shown in section to make a relief channel visible do.

Wie die Fig. 1 zeigt, sind die Sicherungen 2b in den Isolierkalotten des Sicherungsträgers 2 in atmosphärischer Luft 2' untergebracht und können daher nach Durchführung der üblichen Erdungs- und Sicherheitsmaßnahmen ausgewechselt werden.As FIG. 1 shows, the fuses 2b are in the insulating caps of the fuse carrier 2 housed in atmospheric air 2 'and can therefore be replaced after the usual earthing and safety measures have been carried out.

Weiterhin zeigt die Fig. 1, daß die offene Stelle der Isolierkalotten mit einer platzsparenden Dichtung 3 versehen ist.Furthermore, Fig. 1 shows that the open point of the insulating caps is provided with a space-saving seal 3.

Diese Dichtungen verschließen in vorteilhafter Weise gleichzeitig gegen äußere Einflüsse, wie Luftfeuchte und/oder Schmutz.These seals advantageously close at the same time against external influences such as humidity and / or dirt.

Eine Wartung, z.Bw Reinigung des Isolierkörpers der Sicherung, kann daher entfallen.Maintenance, e.g. cleaning the insulating body of the fuse, can therefore not applicable.

Gleichzeitig erlaubt die elektrische Dichtung 3 die Übertragung von Kräften und Bewegungen,z.B.At the same time, the electrical seal 3 allows the transmission of Forces and movements, e.g.

die des Schlagstiftes 4.that of the striker 4.

Die in Fig. 1, insbesondere in der Fig 2 dargestellten Entlastungskanäle 5 mit den Verschlußkappen 6 gewährleisten über lange Isolierstrecken eine Luftausdehnung in den Isolierkalotten bei Erwärmung der Sicherungen.und eine Druckentlastung im Fall eines Versagens der Sicherungen.The relief channels shown in FIG. 1, in particular in FIG 5 with the sealing caps 6 ensure air expansion over long insulating distances in the insulating caps when the fuses heat up. and a pressure relief in the In the event of a fuse failure.

Außerdem ist die Entlastung so gerichtet, daß der Bedienende nicht von den heißen Gasen, getroffen werden kann, indem dic Ausgänge der Kanäle um 900 zur fledienungsrichtung für den Sicherungsträger versetzt angeordnet sind.In addition, the discharge is directed that the Operators not affected by the hot gases, by dic exits of the channels offset by 900 to the direction of flow for the fuse carrier are.

Die entsprechenden Verschlußkappen 6 verhindern eine Verschmutzung und werden im Störungsfall z.B.The corresponding closure caps 6 prevent contamination and in the event of a fault, e.g.

durch den entstehenden Gasüberdruck abgworfen.thrown off by the resulting excess gas pressure.
