Description

.Elektrisch fremderregte Kontaktrelais mit periodisch arbeitenden Kontakten und Einstellmöglichkeit für Kontaktdauer und Frequenz sind bekannt. Erfirrdurngsgemäß wird die Erregung des Elektromagneten solcher Kontaktrelais über eine Kippschaltung gesteuert. Es Icann hierfür eine beliebige Kippschältuiig verwendet werden, z. B. eine Schaltung-mit einer Glimmlampe. Die Amplituden der Kontaktschwingungen lassen sich dann leicht auf den gewünschten Betrag einstellen, und auch die Frequenz ist durch einfache elektrische Mittel, wie z. B. durch die Änderung einer Spannungshöhe oder eines Widerstandes, einstellbar. Um ein exaktes Arbeiten der Kontakteinrichtungen zu sichern, empfiehlt es sich, Reibungsverluste zu vermeiden, indem man den Anker federnd aufhängt, beispielsweise an einer sich verhiegenden .oder verdrehenden Blattfeder. Damit die gesteuerten Kontaktbewegungen nicht durch die Kontaktschließung merklich gestört werden, ist es zweckmäßig, den Kontakt nur einseitig arbeiten zu lassen. Die Schwingungsamplituiden sind dabei nur etwa halb so groß wie bei sinusförmigen Kontaktschwingungen. Durch die Wahl der Amplitudengröße der Schwingungen kann man dieDauerder-einzelnenKontaktschließungenbeeinflussen. .Dadurch, daß-die Kontaktschwingungen mit rein elektrischen Mitteln willkürlich geändert werden können, ist es möglich, den Apparat, der die Kontaktsteuerung leistet, bei verschiedenenReglern einzusetzen, da seine Kontaktzeiten und seine Kontaktfrequenz in weiten Grenzen einstellbar und anpaßbar sind.Electrically separately excited contact relays with periodically operating Contacts and setting options for contact duration and frequency are known. According to success is the excitation of the electromagnet of such contact relays via a toggle switch controlled. Any Kippschäluiig can be used for this, e.g. B. a circuit with a glow lamp. Let the amplitudes of the contact vibrations then easily adjust to the desired amount, and also the frequency is by simple electrical means such as B. by changing a voltage level or a resistor, adjustable. To ensure that the contact devices work precisely To secure it, it is best to avoid frictional losses by removing the anchor resiliently suspended, for example on a twisting or twisting leaf spring. So that the controlled contact movements are not noticeable through the contact closure are disturbed, it is advisable to let the contact only work on one side. The oscillation amplitudes are only about half as large as with sinusoidal ones Contact vibrations. By choosing the amplitude size of the oscillations one can Influence the duration of the individual contact closures. .By that-the contact vibrations can be changed arbitrarily by purely electrical means, it is possible to use the device that performs the contact control with various controllers, since its contact times and its contact frequency can be set within wide limits and are customizable.

Ein Ausführungsbeispiel für den Erfindungsgedanken ist in einer Schaltskizze angedeutet.An embodiment for the inventive idea is in a circuit diagram indicated.

In der Zeichnung ist angenommen, daß die zu regelnde Größe durch die Umlaufgeschwindigkeit eines kleinen -Generators i ausgedrückt sei. -Es soll die Spannung-dieses Generators ii konstant gehalten werden. Diese Spannung kann abgegriffen werden an zwei Klemmen 2. Die Erregerwicklung 3. dieser Dynamomaschine -i liegt über einen schwingenden Kontaktq. an den Kollektorbürsten des Generators i. Der Kontakt q. wird durch eine Magnetwicklung 5 periodisch geöffnet und wieder geschlossen. Die Erregung der Spule 5 schwankt- periodisch im Rhythmus des Ansprechens einer Kippschaltung 6, die schematisch angedeutet ist. Die Kippschaltung 6 kann von einer veränderlichen Spannung, die von einem Vorwnderstand 7 der Magnetspule 5 abgegriffen wird, gespeist werden, beispielsweise um dadurch die Frequenz der Kippschaltung 6 zu ändern. Durch die Größe des Vorwiderstandes 7 kann die Erregung der Magnetspule 5 beeinflußt werden und d-aidurch die Amplitude der Schwingungen des Kontaktes q. und die Dauer der einzelnen Kontaktschlüsse gewählt werden.In the drawing it is assumed that the variable to be controlled by the The rotational speed of a small generator i is expressed. -It's supposed to Voltage-this generator ii can be kept constant. This voltage can be tapped are connected to two terminals 2. The excitation winding 3. This dynamo machine -i is connected via a vibrating contact q. on the collector brushes of the generator i. Of the Contact q. is periodically opened and closed again by a magnetic winding 5. The excitation of the coil 5 fluctuates periodically in the rhythm of the response Toggle circuit 6, which is indicated schematically. The flip-flop 6 can be of a variable voltage, which is tapped from a Vorwnderstand 7 of the solenoid coil 5 is fed, for example to thereby increase the frequency of the flip-flop 6 to change. Due to the size of the series resistor 7, the excitation of the magnet coil 5 and d-aby the amplitude of the vibrations of the contact q. and the duration of the individual contact closures can be selected.

Die Kippschaltung 6, die Magnetspule 5 mit ihrem Vorwi@derstand 7, der ebenfalls einstellbar sein kann, und der schwingende Kontakt q. sind- in einem Gehäuse 8 vereinigt. Diese im Gehäuse 8 vereinigte Apparatur kann auch bei einem anders bemessenen Generator i eingesetzt werden, da die Schwingungen des Kontaktes q. dien Erfordernissen anpaßbar sind. Die im 1Vleßinstrumentenbau üblichen Maßnahmen zur Kompensation von Temperatureinflüssen können auch bei dem Regler gemäß der Erfindung angewendet werden. Das eigentliche Reglerrelais 5, q. kann ein auf magnetischer Anziehung beruhendes Relais sein, und durch geeignete Wahl .des Arbeitspunktes :der magnetischen Zugkraftkurve einerseits und der Direktionskraftkurve andererseits kann man ein stabiles Arbeiten des Relais bei gewollten Werten der Frequenz- und der Amplitude erreichen. Gegenüber dem bekannten Tirrill-Regler ist das neue Gerät .-durch-eine wesentlich einfachere Bauweise und ein geringeres Gewicht sowie einen geringeren kaumbedarf ausgezeichnet.The flip-flop 6, the solenoid 5 with its Vorwi @ resistor 7, which can also be adjustable, and the oscillating contact q. are in one Housing 8 united. This combined in the housing 8 apparatus can also with a different sized generator i can be used because the vibrations of the contact q. the requirements are adaptable. The usual measures in the construction of measuring instruments to compensate for temperature influences can also be used in the controller according to the invention be applied. The actual regulator relay 5, q. can one on magnetic Be attraction-based relay, and through a suitable choice of the operating point: the magnetic tensile force curve on the one hand and the directional force curve on the other you can have a stable operation of the relay with desired values of the frequency and reach the amplitude. The new device is opposite the well-known Tirrill controller .-by-a much simpler construction and a lower weight as well as a lower hardly required excellent.
