543089543089 Die Erfindung betrifft ein elektromagnetisches Relais für Gleichstrom-Schnellschalter, bei dem die Regelung der Ausklink-Stromstärke durch die Änderung der Reluktanz eines magnetischen s Hilfskreises bewirkt wird, der mit demjenigen Teile des magnetischen Kreises des Relais in Nebenschluß liegt, welcher durch den Antriebsanker des Klinkengestänges hindurchgeht.
Das Wesen der Erfindung besteht darin, daß
The invention relates to an electromagnetic relay for direct current high-speed switches, in which the control of the release current is effected by changing the reluctance of a magnetic auxiliary circuit which is shunted with that part of the magnetic circuit of the relay which is caused by the drive armature of the ratchet linkage passes through.
The essence of the invention is that
ίο der magnetische Hilfskreis mit einer oder mehreren kurzgeschlossenen Windungen versehen ist.ίο the magnetic auxiliary circuit with one or more short-circuited turns is provided. Ein Ausführungsbeispiel eines Relais nach der Erfindung ist auf der Zeichnung dargestellt.An embodiment of a relay according to the invention is shown in the drawing. Der magnetische Hauptkreis A des Relais wird durch die Wicklung B1 erregt, in welcher der den Schalter durchlaufende Strom umläuft. In dem Fall, wo die nominelle Stärke des Schalters hoch ist, wird die ErregungswicklungThe main magnetic circuit A of the relay is energized by winding B 1 in which the current flowing through the switch circulates. In the case where the nominal strength of the switch is high, the excitation winding will «ο auf einen einfachen Stab oder auf zwei parallele Stäbe, wie sie in der Zeichnung im Querschnitt durch B2 angedeutet sind, verringert.«Ο to a simple rod or to two parallel rods, as indicated in the drawing in cross section by B 2 , reduced. Der magnetische Kreis A verteilt sich in die Zweige C und Cm. The magnetic circuit A is divided into branches C and C m . Im ersten Kreis liegt der Anker D, welcher durch Vermittlung der Stange T auf das Klinkgestänge des Schalters einwirkt und dessen Ausklinkung hervorruft. Der Kreis C1n ist mit Bezug auf den Kreis C beweglich.In the first circle is the armature D, which acts on the latch linkage of the switch through the intermediary of the rod T and causes it to be disengaged. The circle C 1n is movable with respect to the circle C. Durch Änderung des Spaltes e2 kann man eine gewisse, mehr oder weniger große Teilmenge Φ2 des gesamten Flusses Φ im magnetischen Kreis Cm abzweigen, so daß der Fluß Φχ in dem den beweglichen Anker enthaltenden Kreis konstant bleibt, welches auch der Wert von Φ und infolgedessen des Erregungsstromes in B1 sei. Man regelt also die Ausklinkstärke durch Änderung des Spaltes e2, während der Spalt ex konstant bleibt. Man kann so die mechanischen Charakteristiken der Ausklinkung konstant halten, welche Stromstärke· man sich auch festgesetzt hat.By changing the gap e 2 one can branch off a certain, more or less large subset Φ 2 of the total flux Φ in the magnetic circuit C m , so that the flux Φ χ in the circle containing the movable armature remains constant, which is also the value of Φ and consequently the excitation current in B 1 . The notch strength is therefore regulated by changing the gap e 2 , while the gap e x remains constant. In this way, the mechanical characteristics of the notch can be kept constant, whatever current strength one has established. Da das Relais einen Schalter für Gleichstrom in Tätigkeit setzen soll, sind nun zwei Kurzschlußwindungen S an dem magnetischen Hilfskreis angeordnet. Diese Windungen widersetzen sich einer schnellen Erhöhung des magnetischen Flusses im Kreis C7n im Augenblick eines Kurzschlusses, so daß der größte Teil des Flusses Φ sich in den Stromkreis C abzweigt und die Ausklinkgeschwindigkeit verstärkt wird.Since the relay is intended to activate a switch for direct current, two short-circuit windings S are now arranged on the auxiliary magnetic circuit. These turns resist a rapid increase in the magnetic flux in circuit C 7n at the moment of a short circuit, so that most of the flux Φ branches off into circuit C and the release speed is increased. Bei der beschriebenen Anordnung wird die Änderung des magnetischen Widerstandes des magnetischen Hilfskreises dadurch erreicht, daß zwischen diesem Kreis und dem Hauptkreis ein Spalt gelassen ist, wobei der Hilfskreis mit Bezug auf den Hauptkreis beweglich ist. Dasselbe Ergebnis kann auch durch einen oder mehrere feste magnetische Kreise erreicht werden, die parallel mit dem Kreis C angeordnet sind und deren magnetischen Widerstand man dadurch ändern kann, daß man auf zwischenliegende Spalte, ähnlich dem Spalt C1, oder auf irgendein anderes den magnetischen Fluß beeinflussendes Charakteristikum einwirkt.In the arrangement described, the change in the magnetic resistance of the auxiliary magnetic circuit is achieved in that a gap is left between this circuit and the main circuit, the auxiliary circuit being movable with respect to the main circuit. The same result can also be achieved by one or more fixed magnetic circuits which are arranged in parallel with the circuit C and whose magnetic reluctance can be changed by applying the magnetic flux to intermediate gaps, similar to gap C 1 , or any other influencing characteristic acts.
