Definitions
- the invention relates to a fuse connection device for encapsulated medium-voltage switchgear in accordance with the preamble of claim 1.
- a fuse is inserted in the fuse connection device, which causes an electrical shutdown.
- the striker pin of the fuse has no function. It may be useful to have an alternative to triggering by electrical means.
- the invention is therefore based on the object of strengthening the fuse connection device to such an extent that mechanical triggering is also possible.
- the advantages achieved by the invention are that the mechanical triggering is made possible, the customer remains in the previous mode of operation and many specifications and lying regulations based on firing pins can be complied with.
- a bushing 3 is used in the wall 2 of a switchgear 1.
- the implementation has the task of supplying a cable conductor 4 from the interior of the switchgear to an HV HRC cartridge 7.
- a connecting part 5 is used which has an interior 12 with three openings 13, 15 and 17 to the outside.
- the opening 13 is designed conically on the inside such that an outer cone 14 of the bushing 3 can be inserted into this opening.
- the cable conductor 4 in the bushing is connected at the end inside the interior to a tab 20 which is supported on the inner edges of the connecting part and is then fixed with a screw connection.
- the tab serves the connection between the cable conductor and a contact cap 19 of the fuse cartridge.
- the second opening 15 serves to accommodate the fuse cartridge, which extends so far into the Inserted connector is that the contact cap is inside the interior.
- the live parts of the fuse cartridge are now completely encapsulated.
- the connecting part is made of a rubber-elastic material and includes the porcelain body 16 of the fuse cartridge, so that a good seal is achieved at this point.
- the third opening 17 serves to receive a removable plug 18. Through this opening, the condition of the release pin 21 of the HH fuse cartridge can be viewed.
- a bolt (25) is arranged inside the connecting part.
- the wall section of the connecting part closest to the bolt head is designed as a force transmission zone 26.
- circular grooves 27 and 28 are provided inside and outside, which together with the elasticity of the material of the connecting part ensure a sufficient bulge at this point.
- a lever 29 is attached, one end of which is connected to the power transmission zone and the other end of which is operatively connected to the mechanical drive of a switching device.
- it is inserted in a holder 30 which is equipped with two arms 31 and 32 lying one above the other.

Abstract
Description
Die Erfindung bezieht sich auf eine Sicherungsanschlußeinrichtung für gekapselte Mittelspannungsschaltanlagen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a fuse connection device for encapsulated medium-voltage switchgear in accordance with the preamble of
Nach der Hauptanmeldung 2 32 44 424.9 ist in der Sicherungsanschlußeinrichtung eine Sicherung eingesetzt, die auf elektrischem Wege eine Ausschaltung herbeiführt. Bei einer Auslösung übt der Schlagstift der Sicherung keine Funktion aus. Es kann u.U. von Nutzen sein, eine Alternative zu der Auslösung auf elektrischem Wege zu haben.After the main application 2 32 44 424.9, a fuse is inserted in the fuse connection device, which causes an electrical shutdown. When triggered, the striker pin of the fuse has no function. It may be useful to have an alternative to triggering by electrical means.
Der Erfindung liegt daher die Aufgabe zugrunde, die Sicherungsanschlußeinrichtung soweit zu ertüchtigen, daß auch eine mechanische Auslösung möglich ist.The invention is therefore based on the object of strengthening the fuse connection device to such an extent that mechanical triggering is also possible.
Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen konstruktiven Maßnahmen gelöst.This object is achieved by the design measures specified in the characterizing part of
Die mit der Erfindung erzielten Vorteile bestehen darin, daß die mechanische Auslösung ermöglicht wird, dem Kunden die bisherige Betriebsweise erhalten bleibt und viele auf Schlagstiften beruhende Spezifikationen und Lievervorschriften eingehalten werden können.The advantages achieved by the invention are that the mechanical triggering is made possible, the customer remains in the previous mode of operation and many specifications and lying regulations based on firing pins can be complied with.
Vorteilhafte Aus- und Weiterbildungen des Gegenstandes nach Anspruch 1 sind den Unteransprüchen zu entnehmen.Advantageous developments and further developments of the subject matter according to
Hierbei erweist es sich als zweckmäßig, die Kraftübertragungszone des elastischen Anschlußteils mit kreisförmigen Rillen innen und außen auszubilden (Anspruch 2), so daß eine nutzbare Auswölbung gewährleistet ist.It proves to be expedient to design the force transmission zone of the elastic connecting part with circular grooves on the inside and outside (claim 2), so that a usable bulge is ensured.
Um eine sichere Führung des Bolzens zu erreichen, ist es zweckmäßig, diesen in einer Halterung mit zwei übereinander liegenden Armen zu führen (Anspruch 6).In order to achieve safe guidance of the bolt, it is expedient to guide it in a holder with two arms lying one above the other (claim 6).
Um die Wandung des Anschlußteils vor Beschädigungen zu schützen, erscheint es zweckmäßig, den mit einem halbrunden Kopf versehenen Bolzen in Kunststoff auszuführen (Ansprüche 7 und 8).In order to protect the wall of the connecting part from damage, it appears expedient to design the stud provided with a semicircular head in plastic (
Ein Ausführungsbeispiel der Erfindung ist in einer Zeichnung dargestellt und wird im folgenden näher erläutert:
- Die Figur zeigt eine Sicherungsanschlußeinrichtung mit mechanischer Auslösung in Seitenansicht, im Schnitt.
- The figure shows a fuse connection device with mechanical release in side view, in section.
Wie die Figur zeigt, ist in der Wand 2 einer Schaltanlage 1 eine Durchführung 3 eingesetzt. Die Durchführung hat die Aufgabe, einen Kabelleiter 4 aus dem Inneren der Schaltanlage einer HH-Sicherungspatrone 7 zuzuführen. Hierzu dient ein Anschlußteil 5, das einen Innenraum 12 mit drei Öffnungen 13, 15 und 17 nach außen hin besitzt. Die Öffnung 13 ist innen konusförmig derart gestaltet, daß ein Außenkonus 14 der Durchführung 3 in diese Öffnung einsteckbar ist. Um einen festen Sitz des Anschlußteils auf die Durchführung zu erreichen, ist der in der Durchführung befindliche Kabelleiter 4 am Ende innerhalb des Innenraumes mit einer Lasche 20 verbunden, die sich an den Innenkanten des Anschlußteils abstützt und anschließend mit einer Schraubverbindung festgesetzt ist. Die Lasche dient der Verbindung zwischen dem Kabelleiter und einer Kontaktkappe 19 der Sicherungspatrone. Die zweite Öffnung 15 dient der Aufnahme der Sicherungspatrone, die so weit in das Anschlußteil eingeschoben ist, daß die Kontaktkappe sich innerhalb des Innenraumes befindet. Damit sind die spannungsführenden Teile der Sicherungspatrone vollständig eingekapselt. Das Anschlußteil ist aus einem gummielastischen Werkstoff hergestellt und umfaßt den Porzellankörper 16 der Sicherungspatrone saugend, so daß an dieser Stelle eine gute Dichtung erreicht wird. Die dritte Öffnung 17 schließlich dient der Aufnahme eines herausnehmbaren Stopfens 18. Durch diese Öffnung kann der Zustand des Auslösestiftes 21 der HH-Sicherungspatrone in Augenschein genommen werden.As the figure shows, a
In der Achse des Schlagstiftes der HH-Sicherungspatrone ist ein Bolzen (25) innerhalb des Anschlußteils angeordnet. Der dem Bolzenkopf nächstgelegene Wandungsabschnitt des Anschlußteils ist als eine Kraftübertragungszone 26 ausgebildet. Hierzu sind im Inneren und Äußeren kreisförmige Rillen 27 und 28 angebracht, die zusammen mit der Elastizität des Werkstoffs des Anschlußteils für eine ausreichende Auswölbung an dieser Stelle sorgen. Außerhalb des Anschlußteils ist ein Hebel 29 angebracht, dessen eines Ende an die Kraftübertragungszone gelegt ist und dessen anderes Ende mit dem mechanischen Antrieb eines Schaltgerätes in Wirkverbindung steht. Um dem Bolzen eine sichere Führung zu geben, ist dieser in einer Halterung 30 eingesetzt, die mit zwei übereinanderliegenden Armen 31 und 32 ausgerüstet ist.In the axis of the striker of the HH fuse cartridge, a bolt (25) is arranged inside the connecting part. The wall section of the connecting part closest to the bolt head is designed as a
