- the connector has an interior 12 which has three openings 13, 17 and 25 to the outside.
- the opening 13 is designed conically on the inside in such a way that the 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 with a tab 20 which is supported on the inner edges of the connecting part and is then fixed with a screw connection.
- the tab is used for the connection between the cable conductor and a contact cap 19 of the HV backup cartridge.
- the second opening 17 serves to receive a removable one. Plug 18. Through this opening, the condition of the release pin 21 can be viewed, i.e. that is, it can easily be checked at any time whether the fuse has responded.
- the third opening 25 is used to hold the HV backup cartridge.
- the diameter of the opening 25 is much larger than the diameter of the HR fuse cartridge.
- the contact between the contact tab and the contact cap is made by a contact spring 26 which is screwed to the contact tab.
- the connector 10 and 11, not shown, is designed in the same way as the connector 5, so that a detailed description is omitted.
- the connection between the connecting parts 5 and 10 or 11 is made by a plastic tube 27.

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 P 32 44 424.9 wird die Kurzschlußsicherheit einer gekapselten Mittelspannungsschaltanlage durch den Einsatz einer Hochspannungs-Hochleistungs-Sicherungspatrone (HH-Sicherung) erreicht. Hierzu sind zwei Anschlußteile vorgesehen, in welche die HH-Sicherungspatrone eingesetzt ist. Die elektrische Verbindung der HH-Sicherungspatrone zur Schaltanlage einerseits und zu einem Anschlußkabel andererseits erfolgt mittels Kontaktelementen in den Anschlußteilen. Die Gestaltung der Anschlußteile bringt es mit sich, daß ein Auswechseln der HH-Sicherungspatrone problematisch ist und außerdem die erforderliche Spannungsfestigkeit beeinträchtigen kann.According to main application P 32 44 424.9, short-circuit protection of an encapsulated medium-voltage switchgear is achieved by using a high-voltage, high-performance fuse cartridge (HV fuse). For this purpose, two connecting parts are provided, in which the HH fuse cartridge is inserted. The electrical connection of the HV HRC cartridge to the switchgear on the one hand and to a connection cable on the other hand is made by means of contact elements in the connection parts. The design of the connection parts means that replacing the HV HRC cartridge is problematic and can also impair the required dielectric strength.
Der Erfindung liegt daher die Aufgabe zugrunde, die Sicherungsanschlußeinrichtung der zuvor geschilderten Art dahingehend zu verbessern, daß das Einsetzen und Auswechseln der HH-Sicherungspatrone vereinfacht und die Spannungsfestigkeit erhöht werden.The invention is therefore based on the object of improving the fuse connection device of the type described above in such a way that the insertion and replacement of the HV fuse cartridge are simplified and the dielectric strength is increased.
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 erweiterten öffnungen in den Anschlußteilen eine erhebliche Montageerleichterung beim Einsetzen und Auswechseln der HH-Sicherungspatrone mit sich bringen. - Durch den Verzicht von äußeren leitfähigen Belägen auf den Anschlußteilen,die an geeigneter Stelle geerdet sind, und den Verzicht von entsprechenden leitenden Belägen im Inneren der Anschlußteile zur Vermeidung von hohen Feldstärken wird die Herstellung der Anschlußteile wesentlich vereinfacht. Die erforderliche Spannungsfestigkeit wird durch eine Abdichtung zwischen den Anschlußteilen und einem die Anschlußteile verbindenden Kunststoffrohr an der korrespondierenden Dichtungsfläche erzielt.The advantages achieved by the invention are that the widened openings in the connecting parts make installation considerably easier when inserting and replacing the HV backup cartridge. - By dispensing with external conductive coverings on the connection parts, which are grounded at a suitable point, and by dispensing with corresponding conductive coverings inside the connection parts to avoid high field strengths, the production of the connection parts is considerably simplified. The required dielectric strength is achieved by a seal between the connection parts and a plastic tube connecting the connection parts on the corresponding sealing surface.
Ein Ausführungsbeispiel der Erfindung ist in einer Zeichnung dargestellt und wird im Folgenden näher erläutert.An embodiment of the invention is shown in a drawing and is explained in more detail below.
Es zeigt
die Figur eine Sicherungsanschlußeinrichtung in Seitenansicht, im Schnitt.It shows
the figure shows a fuse connection device in side view, in section.
Nach der Figur 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. Als Anschlußteil zwischen der Durchführung und der Sicherungspatrone dient ein Anschlußteil 5. Dieses Anschlußteil besitzt zur Anlagenseite eine konusförmige Öffnung, die ein Aufstecken des Anschlußteils auf die Durchführung gestattet, die im Verbindungsbereich mit dem Anschlußteil einen entsprechenden Außenkonus aufweist. Das Anschlußteil besitzt einen Innenraum 12, der drei Öffnungen 13, 17 und 25 nach außen hin aufweist. Die öffnung 13 ist innen konusförmig derart gestaltet, daß der Außenkonus 14 der Durchführung 3 in diese öffnung einsteckbar ist.According to the figure, a bushing 3 is used in the
Um einen festen Sitz des Anschlußteils auf der 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 Verbingung zwischen dem Kabelleiter und einer Kontaktkappe 19 der HH-Sicherungspatrone. Die zweite öffnung 17 dient der Aufnahme eines herausnehmbaren. Stopfens 18. Durch diese öffnung kann der Zustand des Auslösestifts 21 in Augenschein genommen werden, d. h., es kann hier jederzeit leicht überprüft werden, ob die Sicherung angesprochen hat.In order to achieve a tight fit of the connecting part on the bushing, the cable conductor 4 in the bushing is connected at the end inside the interior with a
Die dritte Öffnung 25 dient der Aufnahme der HH-Sicherungspatrone. Der Durchmesser der öffnung 25 ist dabei wesentlich größer als der Durchmesser der HH-Sicherungspatrone. Der Kontakt zwischen der Kontaktlasche und der Kontaktkappe wird durch eine Kontaktfeder 26 hergestellt, die mit der Kontaktlasche verschraubt sind.The
Das nicht dargestellte Anschlußteil 10 bzw. 11 ist in gleicher Weise ausgeführt wie das Anschlußteil 5, so daß auf eine nähere Beschreibung verzichtet wird. Die Verbindung zwischen den Anschlußteilen 5 und 10 bzw. 11 wird durch ein Kunststoffrohr 27 hergestellt. Die spannungsmäßige Abdichtung erfolgt dabei zwischen den Anschlußteilen 5, 10 bzw. 11 und dem Kunststoffrohr an einer gemeinsamen Dichtungsfläche 28.The connector 10 and 11, not shown, is designed in the same way as the
