Description
Elektromagnetischer . Selbstschalter nüt je einer auf beiden Stirnseiten der Ausl#ösesp*ule angeordneten Unterbrechungsstelle Bei elektrischen Selbstschaltern, insbesondere Installationsselbstschaltern in Form von Stöpsel-, Element- oder Sockelselbstschalter, ist es mit Rücksicht -auf die kleinen Ab- messungen des Schalters erforderlich, den beim Abschalten auftretenden Lichtb6gen durch magnetische Blasung zum Erlöschen zu bringen. Es ist bereits bekannt, zur Erhöhung der Abschaltleistung mehrere Unterbrechungsstellen anzuordnen, die an beiden Seiten der Auslösespule untergebracht sind. Es ist ferner bekannt, die Unterbrechungskontakte außerhalb der Achsmitte des Spulenkernes so anzuordnen, daß der Lichtbogen während der Ausschaltbewegung nach der Spulenachsmitte zu in ein immer stärkeies Magnetfeld geblasen wird. Bei Selbstschaltern mit auf beiden Stimseiten angeordneten Unterbrechungsstellen, wobei die Unterbrechungsstellen außerhalb der Achsmitte einander gegenüberstehen, würde beiVerwendung nur einer Blasspule je nach derStromrichtung in der Blasspule der eine Lichtbogen nach der Achsmitte, der andere Lichtbogen dagegen nach außen getrieben werden. Sollen beide Lichtbögen nach der Mitte getrieben werden, so müßte durch eine Umleitung der Stromverläuf in dem einen Kontaktpaar zu dem in dem anderen Kontaktpaar gleichgerichtet werden. Das ist nicht immer ohne weiteres möglich.Electromagnetic . Even switch nüt one on both end sides of the triggering # ösesp * molecules arranged interruption point with electrical automatic switches, in particular installation itself switches in the form of Stöpsel-, element or base circuit breaker, it is with respect -to the small dimensions of the switch measurements are required, the at shutdown to extinguish any arcing by means of magnetic blowing. It is already known to arrange several interruption points, which are located on both sides of the trip coil, in order to increase the breaking capacity. It is also known to arrange the interruption contacts outside the center of the axis of the coil core in such a way that the arc is blown into an ever stronger magnetic field during the switching off movement towards the center of the coil axis. In the case of automatic switches with interruption points arranged on both front sides, with the interruption points facing each other outside the center of the axis, if only one blower coil is used, one arc would be driven towards the center of the axis and the other arc would be driven outwards, depending on the direction of current in the blower coil. If both arcs are to be driven towards the middle, the current flow in one contact pair would have to be rectified to that in the other contact pair by a diversion. That is not always easy to do.
Dieser Nachteil wird erfindungsgemäß dadurch beseitigt, da3 die Unterbrechungsst,ellen beiderseits der Längsachse der Auslösespule auf zueinander parallel liegenden Spulenkreisdurchmessern versetzt angeordnet sind.According to the invention, this disadvantage is eliminated by the fact that the interruption points on both sides of the longitudinal axis of the trip coil on coil circle diameters lying parallel to one another are arranged offset.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in den Abb. i und --, schematisch dargestellt. Abb. i zeigt einen Längsschnitt durch den Unterbrechungsraum eines Selbstschalters. Abb. 2 ist ein Querschnitt durch den Spulenraum und die beiden. Unterbrechungsräume.In the drawing, an embodiment of the invention is shown schematically in Figs. I and -. Fig. I shows a longitudinal section through the interruption space of a circuit breaker. Fig. 2 is a cross-section through the coil room and the two. Interruption rooms.
Die beiden Unterbrechungsstellen a und b sind in den Unterbrechungskammern c und d an den beiden Stirnseiten der Auslös#espule e angeordnet, Die Auslösespule e, die gleichzeitig als Blasspule dient, ist so gewickelt, daß bei der in Abb. 2 bei den Unterbrechungsstellen a und b angedeuteten Stromrichtung die Unterbrechungslichtbögen in der Pfeilrichtung nach der Achsmitte zu getrieben werden. Die Lichtbögen werden also in an sich bekannt-er Weise in ein immer stärker werdendes Magnetfeld geblasen und schnell zum Erlöschen gebracht.The two interruption points a and b are arranged in the interruption chambers c and d on the two end faces of the release coil e b, the interruption arcs are driven in the direction of the arrow towards the center of the axis. The arcs are thus blown in a manner known per se into an increasingly stronger magnetic field and quickly extinguished.
