Figurenbeschreibungfigure description

In Figur 1 ist ein Ausführungsbeispiel eines Isolations-Sicherungstrennschalters 100 gemäß Erfindung dargestellt, der beispielsweise an einer Sammelschiene (hier nicht dargestellt) zu befestigen ist. Der Isolations-Sicherheitstrennschalter 100 umfasst ein Unterteil 1, ein Gehäuse 2, drei Bedienungshandgriffe 3 und drei Deckeleinheiten 4.In FIG. 1 an embodiment of an isolation fuse breaker 100 is shown according to the invention, which is to be attached to a busbar (not shown), for example. The isolation safety disconnect switch 100 comprises a lower part 1, a housing 2, three operating handles 3 and three cover units 4.

In den Figuren 2, 3 und 7 ist eine Deckeleinheit 4 in mehreren Ansichten dargestellt. Die einen Bedienungshandgriff 3 tragenden Scharnierösen 21 sind durch eine Schürze 5 verbunden. Die Schürze 5 setzt sich in ein Oberteil 7 fort, das mit einem schräg liegenden Messfenster 14 endet. Im Oberteil 7 ist eine länglich-ovale Öffnung 13 eingeschnitten, in der ein Schieber 9 mit Schiebetaste 12 verschiebbar angeordnet ist. Die Öffnung 13 gibt bei entsprechendem Verschieben des Schiebers 9 an das eine Ende der Öffnung 13 ein Messfenster 14 frei. Die Verschiebung des Schiebers 9 mit Schiebetaste 12 an das andere Ende der Öffnung 13 bewirkt, dass das Messfenster 14 geschlossen wird.In the FIGS. 2, 3 and 7 a lid unit 4 is shown in several views. The operating handle 3 carrying hinge eyes 21 are connected by a skirt 5. The skirt 5 continues into an upper part 7, which ends with a slanted measuring window 14. In the upper part 7, an oblong-oval opening 13 is cut, in which a slider 9 is slidably disposed with sliding button 12. The opening 13 is at a corresponding displacement of the slide 9 to the one end of the opening 13, a measuring window 14 free. The displacement of the slider 9 with the sliding key 12 to the other end of the opening 13 causes the measuring window 14 is closed.

Die Öffnungen 13 sind entlang einer mit Bezugszahl 17 angedeuteten Längssymmetrielinie (vgl. Fig. 7) der Deckeleinheit 4 bzw. der im einmontierten Zustand nacheinander liegenden Deckeleinheiten 4 (vgl. Fig. 1), also im mittleren Teil der Deckeleinheit, angeordnet.The openings 13 are along a direction indicated by reference numeral 17 longitudinal symmetry line (see. Fig. 7 ) of the cover unit 4 or of the cover units 4 successively lying in the installed state (cf. Fig. 1 ), ie in the middle part of the cover unit arranged.

Durch das Freilegen des sich ergebenden Messfensters 14 kann mit einem Schraubenzieher (nicht dargestellt) auf einen etwa rechteckigen Plattenkörper 22 eines Schnellmontagemoduls 16 zugegriffen werden, der sich unterhalb der Deckeleinheit 4 befindet (vgl. Figur 4). Ein solches Schnellmontagemodul 16 kann auch vom Unterteil 1 gelöst werden.By exposing the resulting measuring window 14 can be accessed with a screwdriver (not shown) on an approximately rectangular plate body 22 of a quick-mounting module 16, which is located below the cover unit 4 (see. FIG. 4 ). Such a quick-mounting module 16 can also be released from the lower part 1.

Senkrecht zum Plattenkörper 22 des Schnellmontagemoduls 16 (vgl. Fig. 5) verläuft eine zweiteilige Hülse 23 zur Aufnahme einer Schraube 19, die üblicherweise in eine Einschrauböffnung einer Sammelschiene der Schienenbrücke einsetzbar ist. Vorzugsweise ist der Plattenkörper 22 in einem Materialstück zusammen mit der besagten zweiteiligen Hülse 23 gefertigt.Perpendicular to the plate body 22 of the quick assembly module 16 (see. Fig. 5 ) runs a two-piece sleeve 23 for receiving a screw 19, which is commonly used in a screw-in opening of a busbar of the rail bridge. Preferably, the plate body 22 is made in a piece of material together with said two-piece sleeve 23.

Mit der Schürze 5 ist eine schwenkbare Abdeckung 20 verbunden, die durch den Schieber 9 mit Schiebetaste 12 bei dessen Verstellung (vgl. Figuren 2 und 7) zu öffnen und zu schließen ist. Hierdurch wird eine Mess-Anschlussöffnung 15 geöffnet und geschlossen. In Schließstellung des Schiebers 9 befindet sich eine Blockiervorrichtung 6 in einem Zustand, dass durch Drehung der Blockiervorrichtung 6 eine der Sicherungseinsätze 8 aus der Unterseite der Deckeleinheit 4 herausnehmbar ist.With the skirt 5, a pivotable cover 20 is connected by the slide 9 with the sliding button 12 during its adjustment (see. Figures 2 and 7 ) to open and close. As a result, a measuring connection opening 15 is opened and closed. In the closed position of the slide 9 is a blocking device 6 in a state that one of the fuse links 8 from the bottom of the cover unit 4 is removable by rotation of the blocking device 6.

Um zu verhindern, dass Sicherungseinsätze 8 sich von der Unterseite der Deckeleinheit 4 lösen, wirkt der Schieber 9 als Sperre, so dass es unmöglich ist, die Sicherungseinsätze 8 aus ihren Halterungen zu lösen. Sind die Sicherungseinsätze 8 aus dem Deckel entfernt, kann durch die freie Öffnung 13 mit einem Werkzeug auf die Schraube 19 zugegriffen werden, die sich in dem Schnellmontagemodul 16 befindet.In order to prevent fuse links 8 from disengaging from the underside of the cover unit 4, the slider 9 acts as a lock, so that it is impossible to release the fuse links 8 from their mountings. Are the fuse links 8 removed from the lid, can be accessed through the free opening 13 with a tool on the screw 19, which is located in the quick-mounting module 16.

Das Schnellmontagemodul 16 befindet sich im Unterteil 1 innerhalb einer Einsatzöffnung 18. Das Schnellmontagemodul 16 ist auch in Fig. 4 als getrenntes (oberes Teil der Figur), in die Einsatzöffnung 18 einzusteckendes Konstruktionsteil schematisch dargestellt. Durch die beschriebene Zugänglichkeit der Schraube 19 ist es möglich, dass der Isolation-Sicherungstrennschalter 100 durch Anziehen an die Sammelschiene fest angezogen werden kann, ohne dass die Deckeleinheit 4 vom Unterteil 1 abgehoben werden muss.
