Description
Schlagwettergeschützter Schaltkasten mit mechanischer Verriegelung von Schalter und Deckel Es sind schon Anordnungen von schlagwettergeschützten Schaltkästen bekannt geworden, bei denen sich Schalter und Deckel bei geschlossenem Stromkreis gegenseitig mechanisch verriegeln. Hierbei kann der Deckel bei eingelegtem Schalter nicht abgehoben und bei abgehobenem Deckel der Schalter nicht eingelegt werden, damit der beim Schalten sich bildende Lichtbogen nicht die etwa außerhalb des Schaltkastens befindlichen Gase entzündet.Firedamp-proof switch box with mechanical locking of switch and cover There are already arrangements of firedamp-proof switch boxes become known, in which switch and cover when the circuit is closed mechanically lock each other. The cover can be used when the switch is inserted not lifted off and the switch not inserted when the cover is lifted, so that the arc that forms when switching does not affect the outside of the switch box ignited gases.
Nach der Erfindung wird eine derartige mechanische Verriegelung in einfachster Weise dadurch erzielt, daß sie aus einem zwischen Antrieb und Schalter eingefügten, an dem Deckel gelagerten Kupplungsteil besteht.According to the invention, such a mechanical lock in The simplest way of achieving this is that it consists of one between the drive and the switch inserted coupling part mounted on the cover.
In den Abbildungen ist ein Ausführungsbeispiel nach der Erfindung dargestellt. Abb. i -zeigt den Schalter in einem Aufrißschnitt, Abb.2 eine Ansicht des Schnittes nach der Linie A-A der Abb. i in ausgeschaltetem, Abb. 3 in eingeschaltetem Zustande des Schalters und Abb. q. einen Schnitt durch das Ende des Kupplungsteiles in der Linie B-B, bei geöffnetem und Abb. 5 bei geschlossenem Schalter.In the figures is an embodiment according to the invention shown. Fig. I - shows the switch in an elevation section, Fig.2 is a view of the section along the line A-A of Fig. i in switched off, Fig. 3 in switched on State of the switch and Fig. Q. a section through the end of the coupling part in line B-B, with the switch open and Fig. 5 with the switch closed.
Die von dem Handhebel i i bewegte und in der Wand des Schaltkastens 12 gelagerte Antriebswelle 13 ist über den Kupplungsteil i q. nach der Erfindung mit der, die beweglichen Schaltstücke 15 tragenden Schalterwelle 16 gekuppelt. Diese ist in Lagerböcken 17 drehbar angeordnet, die durch einen Teil i ä miteinander verbunden sind, an dem die Kontaktfinger i9 für die beweglichen Schaltstücke 15 über Isolierteile ao befestigt sind. An dem abnehmbaren Deckel 2 i ist ein Träger 22 befestigt, in dessen unterem Ende der Kupplungsteil i q. drehbar gelagert ist. -Wie aus den Abb. q. und 5 hervorgeht, besitzen die einander zugekehrten Enden der Antriebs- und der Schalterwelle Schlitze 23, in die die entsprechend ausgebildeten Enden 24. des Kupplungsteiles i q. .eingreifen. Bei ge-Gffnetein Schalter nach den Abb. i, 2 und q. wird daher bei Entfernen des Schalterdeckels 2 i' von dem Schaltkasten 12 der Kupplungsteil 1q. durch seinen Träger 22 aus den Schlitzen 23 an den Enden der Wellen herausgezogen und die Antriebswelle 13 von der Schalterwelle 16 dadurch abgekuppelt. Ist der Schalter dagegen eingelegt, so ist ein Herausziehen des Kupplungsteiles 1q. aus den Schlitzen. 23 unmöglich, wie dies aus Abb. 3 und 5 ersichtlich ist, weil die Kreissegmente a 5 der Wellenenden ein Herausziehen nach oben verhindern. Der Deckel a i des Schaltkastens kann also trotz gelöster Deckelschrauben nicht früher von dem Schaltkasten entfernt werden, als bis der Schalter ausgeschaltet ist. The drive shaft 13 moved by the hand lever ii and mounted in the wall of the switch box 12 is via the coupling part i q. according to the invention with the switch shaft 16 carrying the movable contact pieces 1 5. This is rotatably arranged in bearing blocks 17 , which are connected to one another by a part i ä, to which the contact fingers i9 for the movable contact pieces 1 5 are attached via insulating parts ao. A carrier 22 is attached to the removable cover 2 i, in the lower end of which the coupling part i q. is rotatably mounted. - As shown in fig. Q. 5 and 5, the ends of the drive shaft and the switch shaft facing each other have slots 23 into which the correspondingly formed ends 24 of the coupling part i q. .intervention. When open, a switch as shown in Figs. I, 2 and q. therefore, when the switch cover 2 i 'is removed from the switch box 12, the coupling part 1q. pulled out by its carrier 22 from the slots 23 at the ends of the shafts and the drive shaft 13 is thereby uncoupled from the switch shaft 16. If, on the other hand, the switch is inserted, the coupling part 1q must be pulled out. out of the slots. 23 impossible, as can be seen from Fig. 3 and 5, because the circle segments a 5 of the shaft ends prevent pulling out upwards. The cover ai of the switch box cannot be removed from the switch box earlier than until the switch is switched off, despite the cover screws being loosened.
Es ist auch möglich, an Stelle die Enden der Wellen mit Schlitzen 23 zu versehen, diese derartig auszubilden, daß sie in Schlitze des Kupplungsteiles 14 eingreifen. Die Wirkung ist genau die gleiche wie in dem in den Abbildungen beschriebenen Ausführungsbeispiel.It is also possible, instead of providing the ends of the shafts with slots 23, to design them in such a way that they engage in slots of the coupling part 14. The effect is exactly the same as in the exemplary embodiment described in the figures.
