Description

Anordnung zur kontaktlosen Schaltung eines Stromkreises Die Erfindung betrifft eine Anordnung zur kontaktlosen Schaltung eines Stromkreises, vorzugsweise Relaisstromkreises, in dem als Schalter eine Gasentladungsröhre liegt, deren Zündung aus der Wicklung eines Transformators erfolgt, welche über einen magnetisch veränderbaren magnetischen Kreis erregt wird.Arrangement for the contactless switching of a circuit The invention relates to an arrangement for the contactless switching of a circuit, preferably Relay circuit in which a gas discharge tube is located as a switch, its ignition from the winding of a transformer takes place, which is via a magnetically changeable magnetic circuit is excited.

Es ist bekannt, Gasentladungsstrecken über einen Stromkreis zu zünden, der einen Transformator enthält, dessen übertragungseigenschaften durch einen Hilfsstromkreis beeinflußbar sind, der die Anwendung besonderer Schaltmittel voraussetzt. Hierbei sind Schaltkontakte unvermeidlich, wenn nicht der größere Aufwand von kontaktlosen Schaltelementen in Kauf genommen werden soll.It is known to ignite gas discharge paths via a circuit, which contains a transformer, its transmission properties through an auxiliary circuit can be influenced, which requires the use of special switching means. Here Switching contacts are unavoidable, if not the greater expense of contactless Switching elements should be accepted.

Der Erfindung liegt die Aufgabe zugrunde, für explosionsgefährdete Räume eine Einrichtung zu schaffen, welche die Schaltung größerer Ströme auch bei höheren Spannungen ohne Funkenerzeugung ermöglicht. Gemäß der Erfindung ist zur Lösung dieser Aufgabe ein Dreischenkeltransformator vorgesehen, dessen bewegliches Joch wahlweise den Mittelschenkel mit einem der Außenschenkel verbindet.The invention is based on the object for those at risk of explosion Spaces to create a facility that allows the switching of larger currents even in the case of allows higher voltages without generating sparks. According to the invention is for Solution to this problem provided a three-legged transformer whose movable Yoke optionally connects the middle limb to one of the outer limbs.

Ausführungsbeispiele der Erfindung sind nachstehend an Hand der Zeichnungen beschrieben.Embodiments of the invention are given below with reference to the drawings described.

F i g. 1 zeigt eine Schaltung, F i g. 2 einen Transformator mit mechanisch veränderbarem magnetischem Kreis.F i g. 1 shows a circuit, FIG. 2 a transformer with mechanical changeable magnetic circuit.

Bei der Anordnung nach F i g. 1 wird an den Klemmen K1 und h2 eine Wechselspannung zugeführt, welche die Wicklung W1 des Transformators T erregt. Der magnetische Kreis, den die Wicklung W1 umfaßt, kann auf mechanischem Weg wahlweise die Wicklung W2 oder die Wicklung W3 erregen. Zwischen den Wicklungen W2 und W3 ist über einen Widerstand R die Zündelektrode Z der Gasentladungsröhre V angeschlossen. In Reihe mit der Gasentladungsröhre V liegt ein elektrischer Verbraucher, z. B. das Relais S. Je nachdem die Wicklung W2 oder W3 in den magnetischen Kreis der Wicklung W1 einbezogen wird, befindet sich die Zündelektrode Z angenähert auf dem Potential der Kathode oder der Anode der Gasentladungsröhre V, so daß durch mechanische Veränderung des Kernes des Transformators T die Röhre V zündet und das Relais S erregt werden kann. An Stelle der Gasentladungsröhre könnte prinzipiell auch ein steuerbarer Halbleiter eingesetzt werden.In the arrangement according to FIG. 1 is connected to terminals K1 and h2 AC voltage supplied, which excites the winding W1 of the transformer T. Of the Magnetic circuit, which includes the winding W1, can optionally be mechanical energize winding W2 or winding W3. Between the windings W2 and W3 the ignition electrode Z of the gas discharge tube V is connected via a resistor R. In series with the gas discharge tube V is an electrical consumer, for. B. the relay S. Depending on the winding W2 or W3 in the magnetic circuit of the winding W1 is included, the ignition electrode Z is approximately at the potential the cathode or the anode of the gas discharge tube V, so that by mechanical change of the core of the transformer T, the tube V ignites and the relay S is energized can. In principle, a controllable semiconductor could also be used instead of the gas discharge tube can be used.

F i g. 2 zeigt den Transformator T nach F i g. 1 in Seitenansicht. Dieser besitzt den dreischenkligen Kern E, auf dessen Mittelschenkel die Wicklung W1 sich befindet, während die Wicklungen W2 und W3 je auf einem der Außenschenkel angeordnet sind. Das magnetische Joch J kann um ein Gelenk P auf dem Mittelschenkel mit Hilfe des Hebels H gekippt werden. Man kann wahlweise durch Bewegung des Hebels H einen geschlossenen magnetischen Kreis herstellen, der entweder die Wicklungen W1, Wz oder die Wicklungen W1, W3 umfaßt.F i g. 2 shows the transformer T according to FIG. 1 in side view. This has the three-legged core E, on whose middle leg the winding W1 is located, while the windings W2 and W3 are each on one of the outer legs are arranged. The magnetic yoke J can be around a joint P on the middle leg be tilted using the lever H. You can either move the lever H establish a closed magnetic circuit that has either the windings W1, Wz or the windings W1, W3.
