EDMOND JULIEN in BRÜSSEL. Stromunterbrecher für Schaltapparate.EDMOND JULIEN in BRUSSELS. Circuit breaker for switchgear.
Patentirt im Deutschen Reiche vom 16. Februar 1886 ab.Patented in the German Empire on February 16, 1886.
Ein Uebelstand bei Schaltapparaten, bestehend aus einem aus Isolirmasse angefertigten Cylinder, in dessen Mantelfläche an entsprechenden Stellen Contactstücke eingesetzt sind, auf denen die mit den Elementpolen verbundenen Contactfedern schleifen, ist der, dafs bei Entfernung der letzteren von den Contactstücken bezw. bei Stromunterbrechung die dadurch entstehenden Funken ebensowohl die Zungen selbst, sowie auch die Isolirmasse bedeutend beschädigen und schon nach kurzem Gebrauch zerstören.An inconvenience in switchgear, consisting of a cylinder made of insulating material, Contact pieces are used in the jacket surface at corresponding points on which the contact springs connected to the element poles slip, is that when they are removed the latter from the contact pieces respectively. in the event of a power interruption, the resulting sparks as well as the tongues Significantly damage itself, as well as the insulating ground, and after a short period of use destroy.
Gegenstand vorliegender Erfindung bildet die Combinirung eines Stromunterbrechers mit einem solchen Schaltcylinder, welch ersterer in solcher Weise wirkt, dafs die Unterbrechung vor der Entfernung der Federn von den Contactstücken an einer anderen Stelle, an welcher das Ueberspringen von elektrischen Funken keinen Schaden ausübt, stattfindet.The subject of the present invention is the combination of a circuit breaker such a switching cylinder, which the former acts in such a way that the interruption before removing the springs from the contact pieces at another point, at which the jumping over of electric sparks does no harm, takes place.
Auf beiliegender Zeichnung veranschaulicht Fig. ι die Anordnung in der Vorderansicht und Fig. 2 dieselbe in der Seitenansicht.On the accompanying drawing Fig. Ι illustrates the arrangement in the front view and FIG. 2 the same in side view.
Die Anordnung ist eine äufserst einfache und besteht dieselbe in einem bei i angelenkten Hebel R, welcher am gegenüberliegenden Ende mittelst einer Spiralfeder S in seiner normalen, d. h. Contactstellung gehalten wird.The arrangement is extremely simple and consists of a lever R articulated at i , which is held at the opposite end by means of a spiral spring S in its normal, ie contact, position.
Der Stromkreis ist nun dadurch geschlossen, dafs sich ein auf Hebel R befestigtes Contactstück Z gegen ein entsprechendes, auf der Schalterplatte befestigtes Contactstück Z1 stellt, wobei die beiden Stücke Z und Zx mit den Contacten des Schaltapparates in entsprechender elektrischer Verbindung stehen. In der Mitte des Hebels R befindet sich ein fester Daumen D, dessen oberes Ende ein Leitröllchen trägt, welches sich in Rastkerben des unten am Schaltcylinder angebrachten Ringes q legt.The circuit is now closed in that a contact piece Z fastened on lever R is positioned against a corresponding contact piece Z 1 fastened on the switch plate, the two pieces Z and Z x being in corresponding electrical connection with the contacts of the switching apparatus. In the middle of the lever R there is a firm thumb D, the upper end of which carries a guide roller, which rests in notches in the ring q attached to the bottom of the shift cylinder.
In dieser Stellung ist der Stromkreis geschlossen , weil das Contactstück Z durch Feder S an Z1 angedrückt wird, wobei die Federn oder Zungen / einer gewissen Schaltung entsprechen. Sollen aber dieselben auf eine andere Contactreihe gestellt werden, so gleitet bei Drehung des Cylinders das Leitröllchen D aus der Rastkerbe auf den vorstehenden Theil r des Ringes q, wodurch Hebel R nach unten schwingt und die Contactstücke ZZ1 trennt.In this position the circuit is closed because the contact piece Z is pressed against Z 1 by spring S , whereby the springs or tongues / correspond to a certain circuit. If, however, they are to be placed on a different row of contacts, when the cylinder is turned, the guide roller D slides out of the locking notch onto the protruding part r of the ring q, whereby the lever R swings down and separates the contact pieces ZZ 1.
Diese automatische Trennung findet statt, ehe sich die Feder f von den Contacten des Schaltcylinders entfernt, so dafs die Unterbrechung des Stromes bei der Trennung von ZΖλ stattfindet, wo das Sprühen der Funken keinen weiteren Schaden verursacht, indem die Contactstücke ZΖλ sich annähernd kostenlos ersetzen lassen.This automatic separation takes place before the spring f moves away from the contacts of the switching cylinder, so that the current is interrupted when ZΖ λ is separated, where the spraying of the sparks does not cause any further damage, as the contact pieces ZΖ λ are almost free have it replaced.
Die Stellung des Stromunterbrechers kann je nach Erfordernifs von der gezeichneten verschieden sein und der beschriebene Unterbrecher auch in Combinirung mit anderen Schaltapparaten verwendet werden.The position of the circuit breaker can differ from the one shown depending on the requirements and the breaker described can also be used in combination with other switching devices.
