Abstract
Description
Die Erfindung betrifft einen Kurzschlußmelder zur Signalisierung von Überstrom- und Kurzschlußauslösung, in Verbindung mit einem Leistungs- oder Motorschutzschalter, und Funktion einer Kurzschlußsperre durch Rückstellung von Hand vor Ort.The invention relates to a short-circuit detector for signaling overcurrent and short-circuit tripping, in conjunction with a circuit breaker or motor protection switch, and the function of a short-circuit lock by manual reset on site.
Da solche Kurzschlußmelder, insbesondere wenn sie mit einem Leistungs- oder Motorschutzschalter verbunden sind, sowohl bei einem Kurzschluß als auch bei einem Überstrom schalten, ist es wichtig, die Auslösungsart von außen erkennen zu können, wobei der Kurzschlußmelder erst auf Überströme oberhalb des etwa 16-fachen Nennstromes reagieren soll.Since such short-circuit detectors, particularly if they are connected to a circuit breaker or motor protection switch, switch in the event of a short-circuit as well as an overcurrent, it is important to be able to recognize the type of tripping from the outside, the short-circuit detector only detecting overcurrents above the approx. times the nominal current.
Dies wird bei einem bekannten Schutzschalter mit Überstrom- und Kurzschlußauslösevorrichtung, die mit einem Hilfsschalter in Wirkverbindung steht und in der ausgelösten Stellung verriegelt gehalten ist (DE-OS 34 02 850), dadurch erreicht, daß für Kurzschluß- und Überstromauslösung getrennte Auslösewellen mit getrennten, mit dem Hilfsschalter in Wirkverbindung stehenden Verriegelungshebeln vorgesehen sind, die ihrerseits mit getrennten Anzeige- und Rückstellstößeln in Wirkverbindung stehen.This is achieved in a known circuit breaker with overcurrent and short-circuit release device which is operatively connected to an auxiliary switch and is kept locked in the tripped position (DE-OS 34 02 850), in that separate tripping shafts with separate, interlocking levers which are in operative connection with the auxiliary switch are provided, which in turn are operatively connected to separate display and reset plungers.
Um auch beispielsweise in einer zentralen Leitstelle die Unterscheidung vornehmen zu können, kann bei einem solchen Schutzschalter jedem Verriegelungshebel ein getrennter Hilfsschalter zugeordnet sein.In order to be able to make the distinction in a central control center, for example, a separate auxiliary switch can be assigned to each locking lever in such a circuit breaker.
Der Erfindung liegt die Aufgabe zugrunde, einen Kurzschlußmelder nach dem Oberbegriff des Ansprüches 1 dahingehend zu verbessern, daß durch einen einfachen Aufbau ein hohes Maß an Funktionen erreicht wird und die Kurzschlußanzeige und die Rückstellung von Hand durch einen einzigen Indikatorstößel erfolgen können.The invention has for its object to improve a short-circuit detector according to the preamble of
Diese Aufgabe wird gemäß der Erfindung durch den Kennzeichnungsteil des Ansprüches 1 gelöst, während in den Ansprüchen 2 bis 12 besonders vorteilhafte Weiterbildungen der Erfindung gekennzeichnet sind.This object is achieved according to the invention by the characterizing part of
Dadurch, daß der Rückstellknopf des Kurzschlußmelders mit einem Einschaltschieber verbunden ist, der über einen Umlenkhebel mit einem dazu parallel verschiebbaren Auslöse-Sperrschieber in Wirkverbindung steht, der in Auslöserichtung einer Auslösevorrichtung des Leistungs- oder Motorschutzschalters verschiebbar und über einen Auslösezapfen mit dieser Auslösevorrichtung in Auslöserichtung formschlüssig verbunden ist, ergibt sich eine besonders kompakte Bauweise eines solchen Kurzschlußmelders, da der Einschaltschieber und der kombinierte Auslöse-Sperrschieber im Schaltergehäuse unmittelbar nebeneinander angeordnet werden können. Auch wird durch den Umlenkhebel eine besonders zuverlässige Funktionsweise eines solchen Kurzschlußmelders erreicht, und es ist außerdem die Anordnung einer Testöffnung in axialer Verlängerung des Auslöseschiebers an der vorderen Schmalseite des Schaltergehäuses unmittelbar neben dem Rückstellknopf möglich, durch die der Auslöseschieber mittels eines spitzen Gegenstandes, wie ein Schraubendreher oder dergleichen, auch ohne Kurzschlußauslösung und ohne daß der Leistungs- oder Motorschutzschalter, mit dem der Kurzschlußmelder verbunden ist, mit Strom beaufschlagt wird, für Testzwecke von Hand rein mechanisch ausgelöst werden kann.Characterized in that the reset button of the short-circuit detector is connected to a switch-on slide, which is operatively connected via a deflection lever to a trigger-blocking slide which can be displaced in parallel, which can be displaced in the triggering direction of a triggering device of the circuit breaker or motor-protective circuit-breaker and via a trigger pin with this triggering device in the triggering direction is connected, there is a particularly compact design of such a short-circuit detector, since the switch-on slide and the combined trigger-lock slide can be arranged directly next to one another in the switch housing. A particularly reliable functioning of such a short-circuit detector is also achieved by the deflecting lever, and it is also possible to arrange a test opening in the axial extension of the trigger slide on the front narrow side of the switch housing directly next to the reset button, through which the trigger slide by means of a pointed object, such as a Screwdriver or the like, even without short-circuit release and without the circuit breaker or motor protection switch to which the short-circuit detector is connected being supplied with current can be triggered purely mechanically by hand for test purposes.
