Description

Mehrpolige thermische @lstromauslösevorrichtung Die Erfindung bezieht sich auf eine mehrpolige thermische überstromauslösevorrichtung mit senkrecht stehenden, flachseitig hinterein:anderliegenden Binietallstreifen, die ihre Ausbiegung ,auf eine mit ihrer Längsachse in Richtung der Ausbiegung der Bimetallstreifen liegende gemeinsame Auslöseleiste übertragen.Multipole thermal oil current tripping device The invention relates on a multi-pole thermal overcurrent release device with vertical, on the flat side one behind the other: other lying binietal strips, which their curvature on one lying with its longitudinal axis in the direction of the bend of the bimetal strips transfer common trigger bar.

Die Genauigkeit der Auslö.sevorrichtumg hängt davon ab, wie groß der Kräfteverlust bei dieser Übertragung ist. Die Auslöseleiste muß daher möglichst reibungsfrei gelagert sein, damit die Reibungswiderstände ihre Bewegung nicht ungünstig beeinflussen. Bei den bekannten Anordnungen bat die Ausläseleiste ortsfeste Lagerstellen, so daß bei der Bewegung verhältnismäßig hohe Reibungswiderstände hervorgerufen werden, welche die Empfindlichkeit der Ausläsung b:eeinträdhtigen.The accuracy of the release mechanism depends on the size of the There is a loss of strength in this transfer. The trigger bar must therefore as possible be mounted without friction, so that the frictional resistances do not adversely affect their movement influence. In the known arrangements, the Ausläseleiste asked for fixed storage locations, so that relatively high frictional resistance is caused during movement, which the sensitivity of the outlet b: eeinträdhtigen.

Es ist auch schon vorgeschlagen worden, die Auslöseleiste mittels Schlitze auf den freien Enden drehbar :aufgehängter und von den thermischen Auslösegliedern gesteuerter Hebel zu lagern. Auch hier sind die zu überwindenden Reibungswiderstände verhältnismäßig groß.It has also been proposed to use the trigger bar Slots on the free ends rotatable: suspended and from the thermal trip links to store controlled lever. Here, too, are the frictional resistances to be overcome relatively large.

Um nun die- Bewegung der Auslöseleiste fast reibungslos zu machen, ist erfindungsgemäß die Auslöseleiste an den oberen beweglichen: Enden zweier von allen Bimetallstreifen in gabelförmigen öfnungen frei .aufliegend gelagert.In order to make the movement of the release bar almost smoothly, is according to the invention the release bar at the upper movable: ends of two of all bimetallic strips freely in fork-shaped openings.

Ein Ausführungsbeispiel, das nur die für die Erfindung wesentlichen Teile zeigt, ist in den Fig. z und 2 dargestellt, von denen Fig. i eine Vorderansicht und Fig. z eine Seitenansicht der Ausläsevorrichtiung zeigt. Der zu 'steuernde Schaltkontakt i des Ausläsestromkreises sitzt am unteren Ende eines bei 2 drehbaren Hebels 3, der unter dem Einfluß einer Druckfeder 4 steht. Die Druckfeder sucht auf Schließung des Kontaktes r hinzuwirken. Die Auslöseleiste 5 drückt bei der Bewegung in Richtung des Pfeiles 6 die Feder zusammen und veranlaßt so die öffnung des Kontaktes i.An embodiment that is only essential for the invention Parts are shown in Figs. Z and 2, of which Fig. I is a front view and Fig. z shows a side view of the blower device. The switch contact to be controlled i of the release circuit sits at the lower end of a lever 3 that can be rotated at 2, which is under the influence of a compression spring 4. The compression spring tries to close of the contact r. The trigger bar 5 pushes in the direction of movement of the arrow 6 the spring together and thus causes the opening of the contact i.

An den Stellen 7 sind die unteren Enden dreier senkrecht stehender Binietallstreifen 8 eingespannt, deren obere Enden, wie aus Fig. 2 :ersichtlich ist, gabelartig sind. In den Gabeln 9 zweier dieser Bimetallstreifen ist die Ausläseleste 5 gelagert. Die Gabeln 9 fassen hinter Bünde io, sobald sich die. Bimetallstreifen durchbiegen, und bewirken so die Verschiebung der Ausläseleiste 5 in der Pfeilrichtung, wodurch der Kontakt i geöffnet wird. Die Lagerung der Auslöseleiste, erspart auf diese Weise besondere Lagerstellen und bedeutet dalher ,auch eine Vereinfachung in der Bauart der Ausläsevorrichtung.At the points 7, the lower ends of three are more vertical Binietal strips 8 clamped, the upper ends of which, as shown in FIG. 2: can be seen is, are fork-like. The outlet residue is in the forks 9 of two of these bimetallic strips 5 stored. The forks 9 grasp behind frets io as soon as the. Bimetal strips bend, and thus cause the displacement of the outlet strip 5 in the direction of the arrow, whereby the contact i is opened. The storage of the trigger bar saves on this way special bearings and therefore also means a simplification in the design of the discharge device.
