Description
Bei Schützen, Einschaltvorrichtungen u. dgl., die unter schweren Betriebsbedingungen arbeiten, treten leicht Spannungsschwankungen auf, so daß man nie sicher ist, ob die Einschaltspule eine ausreichende Spannung erhält, um voll einzuschalten bzw. eine Spannung, bei der es möglich ist, daß die Spule im eingeschalteten Zustand bei leicht sinkender Spannung ihren Anker losläßt und zurIn contactors, closing devices and the like that operate under severe operating conditions work, voltage fluctuations occur easily, so that one is never sure whether the The closing coil receives sufficient voltage to fully switch on or a voltage in which it is possible that the coil in the switched-on state with slightly sinking Tension lets go of her anchor and
ίο falschen Zeit abschaltet.· Um diesen Mißstand zu beseitigen, dient vorliegende Einrichtung. Hierbei ist ein kleiner Hilfsmagnet vorgesehen, für dessen Wicklung zuerst Kontakt gegeben wird, so daß sie ihren Anker anzieht und dadurch den Kontakt für die Hauptspule des Schützen schließt. Bei richtiger Spannung zieht dann die Hauptspule ihren Anker an und schaltet den Hauptstrom ein. Am Ende der Einschaltbewegung unterbricht sich die Hauptspule selbst. Das Schütz wird aber durch die zuerst eingeschaltete Hilfsspule durch Verklinken mechanisch in der Einschaltstellung festgehalten. Richtet man nun den kleinen Hilfsmagneten so ein, daß er seinen Anker erst bei stark sinkender Spannung losläßt, so wird auch bei größeren SpannungsSchwankungen des Netzes ein Ausschalten nicht eintreten können. Andererseits ist der Strombedarf ein sehr geringer, da die Hauptspule nur im Augenblick der Einschaltbewegung an der Spannung Hegt und somit mit einer sehr stark überlasteten Wicklung versehen werden kann.ίο wrong time turns off. · To this maladministration This facility serves to eliminate it. Here is a small auxiliary magnet provided, for whose winding contact is given first, so that it attracts its armature and thereby the contact for the main coil of the shooter closes. If the tension is correct, the main coil will pull their anchor and switches on the main power. At the end of the switch-on movement, the main coil interrupts itself However, the contactor is mechanically latched when the auxiliary coil is switched on first held in the on position. If you now set up the small auxiliary magnet so, that he only lets go of his anchor when the tension drops sharply, so is the case when the tension is greater Switch off voltage fluctuations in the network cannot enter. On the other hand, the power requirement is very low, since the main coil is only used at the moment Switch-on movement at the voltage and thus with a very heavily overloaded Winding can be provided.
Die Anordnung ist in der Zeichnung in vier Stellungen für ein Schütz dargestellt. Es bezeichnet α den Hauptkontakt und b die Hauptspule des Schützes, deren Kern c durch das Gestänge d die Einschaltung bei α bewirkt, e ist ein Uhterbrechungskontakt für die Hauptspule, f die Rückzugsfeder von a; g ist der Hilfsmagnet mit seiner Wicklung h und seinem Anker i; k ist der eigentliche, durch den Hilfsmagneten g betätigte Kontakt für die Hauptspule b; I ist eine Verriegelungsnase an i, die das Gestänge m in der Einschaltlage der Bürste α festhält. Abb. 1 zeigt die Anordnung im ausgeschalteten Zustande.The arrangement is shown in the drawing in four positions for a contactor. It denotes α the main contact and b the main coil of the contactor, the core c of which causes the activation at α through the linkage d , e is a break contact for the main coil, f the return spring of a; g is the auxiliary magnet with its winding h and its armature i; k is the actual contact for the main coil b actuated by the auxiliary magnet g; I is a locking lug on i, which holds the linkage m in the switched-on position of the brush α. Fig. 1 shows the arrangement in the switched-off state.
Wird durch Schließen eines Kontaktes die Wicklung h an die Spannung gelegt, so zieht der Hilfsmagnet g seinen Anker i an und schließt dadurch den Kontakt k für die Hauptspule b; da in der Ausschaltlage von α auch der Kontakte noch geschlossen ist (s. Abb. 2), so erhält die Hauptspule b Spannung, zieht den Kern c an und schließt den Stromkreis an.der Hauptbürste α (s. Abb. 3). Durch die Bewegung des Gestänges d wird der mit der Hauptbürste α in Verbindung stehende Verriegelungsteil m nach außen bewegt und klinkt sich an der Nase I ein. Zugleich wird aber der Kontakt e geöffnet und die Hauptspule b spannungslos, so daß ihr Kern c herunterfallen kann (s. Abb. 4). Trotzdem bleibt das Schütz eingeschaltet,, da die Bürste α durch die Verriegelung zwischen m und I in ihrer Einschaltlage festgehalten wird. Erst bei Spannungsloswerden des Hilfsmagneten g· und Loslassen seines Ankers i wird die Verriegelung durch m und I aufgehoben, so daß die Ausschaltfeder f die Ausschaltung der Bürste α bewirkt. Zugleich schließt sich der Kontakt e wieder für das nächste Arbeiten. If the winding h is connected to the voltage by closing a contact, the auxiliary magnet g attracts its armature i and thereby closes the contact k for the main coil b; Since the contacts are still closed in the switched-off position of α (see Fig. 2), the main coil b receives voltage, attracts the core c and connects the circuit to the main brush α (see Fig. 3). As a result of the movement of the linkage d , the locking part m connected to the main brush α is moved outwards and latches onto the nose I. At the same time, however, the contact e is opened and the main coil b is de-energized, so that its core c can fall down (see Fig. 4). Nevertheless, the contactor remains switched on, since the brush α is held in its switched-on position by the interlock between m and I. Only when the auxiliary magnet g is de-energized and its armature i is released is the locking by m and I released , so that the switch-off spring f causes the brush α to switch off. At the same time, the contact e closes again for the next work.
