Description
Für gekapselte Verteilungen ist es bekannt, diese schlagwettersicher auszuführen, d.h. sie so zu kapseln, daß eine Entzündung von Gasen, die sich außerhalb des Kastens befinden, nicht eintreten kann. Es wurde auch bereits vorgeschlagen, sämtlichen in einer Niederspannungsverteilung eingebauten Verteilungsschaltern einen Hauptschalter vorzuschalten, der in einem besonderen Gehäuse untergebracht ist und der nur in seiner Ausschaltstellung den· Zugang zu den Verteilungsschaltern gestattet.For encapsulated distributions, it is known to make them fireproof, i.e. they encapsulated in such a way that ignition of gases outside the box cannot occur. It has also been proposed to be all in one To connect a main switch upstream of built-in distribution switches, which is housed in a special housing and which only provides access to the distribution switches in its off position allowed.
Der Hauptschalter hat lediglich den Zweck, die Zuführungsleitungen zu den einzelnen Verteilungsschaltern spannungslos zu machen. Er könnte daher für eine geringe Abschaltleistung bemessen sein, wenn er nicht bei eingeschaltetem Verteilungsschalter bedient werden kann; denn im anderen Falle müßte der Hauptschalter die Last sämtlicher Verteilungsleitungen gleichzeitig schalten.The main switch has only the purpose of the supply lines to the individual To de-energize distribution switches. He could therefore for a low breaking capacity be dimensioned if it cannot be operated with the distribution switch on; because otherwise it would have to the main switch switches the load of all distribution lines at the same time.
Um den Hauptschalter nur für eine geringe Schaltleistung bemessen zu können, sind gemäß der Erfindung sämtliche Verteilungsschalter mechanisch mit dem Hauptschalter derart verriegelt, daß letzterer nur bedient werden kann, wenn sich die Verteilungsschalter in der Ausschaltlage befinden. Es kann ferner die Anordnung so getroffen werden, daß auch in der Ausschaltstellung des Hauptschalters die Verteilungsschalter zwecks Prüfung geschaltet werden können.In order to be able to dimension the main switch only for a low switching capacity, are according to the invention all distribution switches mechanically with the main switch locked in such a way that the latter can only be operated when the distribution switch are in the switch-off position. Furthermore, the arrangement can be made in such a way that that also in the off position of the main switch the distribution switch for the purpose of testing can be switched.
Eine der möglichen AusführungsformenOne of the possible embodiments
ist in der Zeichnung dargestellt. Hierbei erfolgt die mechanische Verriegelung mittels Gestängeteile, die von dem Antriebsorgan der Verteilungsschalter bewegt werden und die beim "Einschalten mit einer an dem Hauptschalter angebrachten Verriegelungsscheibe in Eingriff kommen.is shown in the drawing. The mechanical locking takes place here by means of Linkage parts that are moved by the drive element of the distribution switch and when switching on with a locking disc attached to the main switch come into engagement.
α ist das Schaltglied des Hauptschalters, b und c sind die Schaltglieder der Verteilungsschalter. An letzteren sind Mitnehmer d und e angebracht, die auf die Stange/ so einwirken, daß diese beim Einschalten abwärts bewegt wird. Die Stange/ drückt auf die Klinge £, die unter dem Einfluß der Feder h steht. Mit dem Schaltglied a des Hauptschalters ist eine Rastenscheibe/ verbunden, die Ausnehmungen k besitzt, in die die Klinke £· beim Einschalten der Verteilungsschalter b, c einspringt. α is the switching element of the main switch, b and c are the switching elements of the distribution switch. On the latter, drivers d and e are attached, which act on the rod / so that it is moved downwards when it is switched on. The rod / presses on the blade £, which is under the influence of the spring h . A detent disk / is connected to the switching element a of the main switch and has recesses k into which the pawl £ · jumps when the distribution switches b, c are switched on.
In der Zeichnung sind der Hauptschalter mit dem Schaltglied« und der Verteilerschalter mit dem Schaltglied c leingeschaltet. Der Hebeln hat die Stange/ abwärts bewegt, so daß die Klinke g in der einen Ausnehmung der Scheibe/ liegt. Der Hauptschalter ist verriegelt.- Wird das Schaltglied c in die Ausschaltstellung gebracht, so bewegt sich durch die Kraft der Federh die Stange/ aufwärts, die Verriegelungsseheibe/ wird frei, so daß der Hauptschalter geschaltet werden kann. Befindet sich letzterer in der Ausschaltstellung, so können die Verteilungsschalter b und c wieder leingeschaltet werden. Hierdurch wird aber die Scheibe/ verriegelt. Es kann also der Hauptschalter nur geschaltet werden, wenn sich die Verteilungsschalter in der Ausschaltstellung befinden.In the drawing, the main switch with the switching element and the distribution switch with the switching element c are switched on. The lever has moved the rod / downwards so that the pawl g lies in one recess of the disc /. The main switch is locked. If the switching element c is brought into the off position, the rod / moves upwards by the force of the spring h , the locking disc / is released so that the main switch can be switched. If the latter is in the switch-off position, the distribution switches b and c can be switched on again. This, however, locks the disc /. The main switch can therefore only be switched when the distribution switches are in the switch-off position.
