Abstract

The invention relates to a circuit, comprising a relay made of a coil with a core and an armature which can move when current flows through the coil, and comprising a device which enables the circuit to be supplied with a voltage which is higher than the maximum permissible DC control voltage for the relay. The invention is constituted by the fact that the device comprises a converter (9a), which converts magnetic energy into electrical energy and is exposed to the magnetic field of the coil (3), and an interrupter (7), to which electrical energy can be applied by the converter (9a) and which can be controlled by the latter, is situated in the supply circuit (6) for the coil (3), interrupts the supply current for the coil (3), after said supply current has been turned on, shortly after the magnetic flux of the coil (3) has caused the armature (2) to move, and subsequently turns it on again when the magnetic flux of the coil (3) is just preventing any movement of the armature (2) in the opposite direction. Such a circuit is distinguished by simplicity. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Schaltung, bestehend aus einem Relais aus einer Spule mit Kern und einem bei Stromfluß durch die Spule bewegbaren Anker und bestehend aus einer Vor­ richtung, die die Versorgung der Schaltung mit einer Spannung ermöglicht, die höher ist als die für das Relais zulässige Steuergleichspannung.The invention relates to a circuit consisting of a relay consisting of a coil with a core and one with current flow anchor movable by the coil and consisting of a front direction that supplies the circuit with a voltage allows that is higher than that allowed for the relay DC control voltage.

Mit einer solchen Schaltung kann man Relais, die für bestimm­ te Gleichspannungen ausgelegt sind, mit höheren Spannungen unterschiedlicher Größe betreiben.With such a circuit you can use relays that are intended for te DC voltages are designed with higher voltages operate different sizes.

Bei einer bekannten Schaltung dieser Art ist die Vorrichtung ein Spannungswandler. Dieser ist verglichen mit dem Relais aufwendig und teuer. In a known circuit of this type, the device a voltage converter. This is compared to the relay complex and expensive.  

Der Erfindung liegt die Aufgabe zugrunde, eine demgegenüber einfachere und billigere Schaltung zu schaffen.The invention is based on the object to create simpler and cheaper circuit.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Vorrichtung aus einem Umformer, der magnetische Energie in elektrische Energie umformt und dem Magnetfeld der Spule aus­ gesetzt ist, und einem Unterbrecher besteht, der von dem Um­ former mit elektrischer Energie beaufschlagbar und von diesem steuerbar ist, in dem Versorgungskreis für die Spule liegt, den Versorgungsstrom für die Spule nach dessen Einschaltung unterbricht, kurz nachdem der magnetische Fluß der Spule eine Bewegung des Ankers bewirkt hat, und anschließend wieder ein­ schaltet, wenn der magnetische Fluß der Spule eine Bewegung des Ankers in umgekehrter Richtung gerade noch verhindert.This object is achieved in that the Device from a converter that converts magnetic energy into transformed electrical energy and the magnetic field of the coil is set, and there is an interrupter who is dependent on the order former can be acted upon by electrical energy is controllable in the supply circuit for the coil, the supply current for the coil after it is switched on interrupts shortly after the coil's magnetic flux Has caused movement of the armature, and then on again switches when the magnetic flux of the coil starts moving the anchor in the opposite direction just prevented.

Diese Schaltung ist wesentlich einfacher und billiger als die bekannte.This circuit is much simpler and cheaper than that known.

Weitere Einzelheiten der Erfindung ergeben sich aus der Zeichnung. Darin zeigen:Further details of the invention emerge from the Drawing. In it show:

Fig. 1 und 2 je ein Ausführungsbeispiel der Erfindung. Fig. 1 and 2 according an embodiment of the invention.

In beiden Figuren ist (sind) mit 1 ein Relais, bestehend aus einem Anker 2, einer Spule 3 und einem Kern 4, und mit 5 die Eingangskontakte eines Versorgungsstromkreises 6 für die Spu­ le 3 bezeichnet. In dem Versorgungsstromkreis 6 liegt ein Unterbecher 7. Dieser wird von einer Einheit 8 angesteuert, die ihrerseits von einem Umformer 9a (Fig. 1) bzw. 9b (Fig. 2) beaufschlagt wird. Der Umformer 9a bzw. 9b formt magneti­ sche Energie in elektrische Energie um. Im Falle der Fig. 1 ist der Umformer 9a ein Hall-Element; im Falle der Fig. 2 ist der Umformer 9b eine Spule, die auf dem Kern 4 sitzt.In both figures, 1 is (are) a relay, consisting of an armature 2 , a coil 3 and a core 4 , and 5 denotes the input contacts of a supply circuit 6 for the coil 3 . A subcup 7 lies in the supply circuit 6 . This is controlled by a unit 8 , which in turn is acted upon by a converter 9 a ( FIG. 1) or 9 b ( FIG. 2). The converter 9 a or 9 b converts magnetic energy into electrical energy. In the case of FIG. 1, the converter 9 a is a Hall element; in the case of FIG. 2, the converter 9 b is a coil that sits on the core 4 .

Beide Vorrichtungen arbeiten folgendermaßen:
Wenn nach Einschaltung der bei 5 anliegenden Spannung der magnetische Fluß der Spule 3 einen bestimmten Wert, kurz nachdem der Anker 2 von dem magnetischen Fluß bewegt worden ist, erreicht hat, dann wird der Versorgungsstrom für die Spule 3 durch den Unterbecher 7 abgeschaltet, dies dadurch, daß der Unterbrecher 7 von den Teilen 9a bzw. 9b und 8 ein entsprechendes Signal erhält. Der magnetische Fluß der Spule 3 wird dann wieder kleiner. Kurz bevor der Anker 2 freigege­ ben wird, wird der Versorgungsstrom für die Spule 3 durch den Unterbrecher 7 wieder eingeschaltet. Der Unterbrecher 7 er­ hält von den Teilen 8, 9a bzw. 9b ein entsprechendes Signal.Both devices work as follows:
If after switching on the voltage applied to 5, the magnetic flux of the coil 3 has reached a certain value shortly after the armature 2 has been moved by the magnetic flux, then the supply current for the coil 3 through the sub-cup 7 is switched off, thereby that the interrupter 7 receives a corresponding signal from the parts 9 a and 9 b and 8 . The magnetic flux of the coil 3 then becomes smaller again. Shortly before the armature 2 is released, the supply current for the coil 3 is switched on again by the interrupter 7 . The interrupter 7 he holds a corresponding signal from the parts 8 , 9 a and 9 b.

Die bei 5 anliegende Versorgungsspannung kann also größer sein als die für das Relais 1 zulässige Steuergleichspannung.The supply voltage present at 5 can therefore be greater than the DC control voltage permissible for relay 1 .
