Description

Verfahren zur Steuerung mechanischer Resonanzrelais, insbesondere zur Signalgabe Wenn man eine große Zahl einzelner Frequenzen zum Betrieb von Resonanzrelais und -getrieben mittels überlagerter Wechselstromimpulse benötigt, so ist es schwierig, diese Einzelfrequenzen durch eine Wechselstromquelle zu erzeugen, da die Änderung der Frequenz in einem zu weitem Umfange erfolgen müßte; besonders bei Motorgeneratoren ist dies infolge der allzu großen Drehzahländerungen nahezu ausgeschlossen.Method for controlling mechanical resonance relays, in particular for signaling If you have a large number of individual frequencies to operate resonance relays and driven by superimposed alternating current pulses, it is difficult to to generate these individual frequencies by an alternating current source, since the change the frequency would have to be too wide; especially with motor generators this is almost impossible due to the excessive speed changes.

Erfindungsgemäß wird die gewünschte Verbreiterung des Frequenzbandes dadurch erreicht, daß man die Wechselstromquelle, z. B. einen Motorgenerator, zwar nur innerhalb des normalen Frequenzbereiches, etwa beispielsweise zwischen 25o bis 500 Perioden betreibt und die höheren Periodenzahlen durch eine zusätzliche Frequenzvervielfachung erzeugt, z. B. das Frequenzband von 50o bis iooo Perioden durch Verdoppelung, das von iooo bis 2ooo Perioden durch Vervierfachung des Gru.ndfrequenz#bandes; die Frequenzvervielfachung kann hierbei nach einer der in der Hochfrequenzmaschinentechnik bekannten Methoden, z. B. durch gleichstromgesättigte Transformatoren, durch Kippresonanz, nach dem Goldschmittschen Reflexionsverfahren usw. erreicht werden. Auf diese Weise kann man auch, wenn man durchweg mit höheren Periodenzahlen arbeiten will, als man sie mittels normaler Wechselstromgeneratoren erzeugen kann, ,statt mit ,der Grundfrequenz erst bei verschiedenen höheren Harmonischen beginnen und alle diese Bänder mit einem normalen Niederfrequenzgenerator erzeugen.According to the invention, the desired widening of the frequency band is achieved in that the alternating current source, for. B. operates a motor generator, although only within the normal frequency range, for example between 25o to 500 periods and the higher number of periods generated by an additional frequency multiplication, z. B. the frequency band from 50o to 100o periods by doubling, that from 100o to 2ooo periods by quadrupling the base frequency band; the frequency multiplication can in this case by one of the methods known in high-frequency machine technology, e.g. B. by DC-saturated transformers, by latching resonance, according to the Goldschmitt reflection method, etc. can be achieved. In this way, if you want to work consistently with a higher number of periods than can be generated with normal alternating current generators, instead of starting with the fundamental frequency at different higher harmonics and generating all these bands with a normal low frequency generator.

Will man jedoch, wie es beispielsweise für Gleichstromnetze in Betracht kommt, mit tieferen Periodenzahlen arbeiten, etwa innerhalb des Bereiches von 25 bis ioo Perioden, so kann man gleichfalls normale Wechselstromgeneratoren benutzen, mit denselben das Band 25 bis 5o Perioden direkt und das erste Oktavband 5o bis ioo Perioden durch Frequenzverdopplung erzeugen.However, if one wants to be considered, for example, for direct current networks come, work with lower period numbers, e.g. within the range of 25 up to 100 periods, normal alternating current generators can also be used, with the same the band 25 to 50 periods directly and the first octave band 50 to Generate 100 periods by doubling the frequency.

Für den beispielsweisen Fall eines Grundfrequenzbandes von 25o bis 50o Perioden und einer wahlweisen Verdopplung oder Vervierfachung, z. B. durch gleichstromgesättigte anschaltbare Transformatoren, ergibt sich die Möglichkeit, zugleich mit der Grundfrequenz die erste und zweite Oktave zu erzeugen. Bei mechanischen Resonanzsystemen vermeidet man zweckmäßig das reine Periodenverhältnis 1 :2:4:8, indem man die in Frage kommenden Resonanzsysteme gegen die reinen Oktaven etwas verstimmt, so daß auch, wenn Grundfrequenz, erste und zweite Oktave gleichzeitig überlagert werden, immer jeweils nur ein Resonanzsystem anspricht, z. B. in der Reihenfolge: 250 503 1009 256 516 1037 262usw. reine Okt. 50o iooo 512 1024 Es ist hierbei vorteilhaft, die Spulen der ferngesteuerten Resonanzrelais und -getriebe durch eine geeignet bemessene Kapazität auf die ihnen eigenen Frequenzen abzustimmen, um den Einfluß der unteren Harmonischen elektrisch zu dämpfen.For the example case of a fundamental frequency band of 25o to 50o periods and an optional doubling or quadrupling, e.g. B. by DC-saturated switchable transformers, there is the possibility of generating the first and second octave at the same time with the fundamental frequency. In the case of mechanical resonance systems, it is advisable to avoid the pure period ratio 1: 2: 4: 8 by detuning the resonance systems in question somewhat against the pure octaves, so that even if the fundamental frequency, the first and second octave are superimposed at the same time, only one is always at a time Resonance system responds, e.g. B. in the order: 25 0 5 0 3 100 9 256 5 1 6 1 0 37 262 etc. pure Oct. 50o iooo 512 1024 It is advantageous here to tune the coils of the remote-controlled resonance relays and gears to their own frequencies by means of a suitably dimensioned capacitance, in order to electrically dampen the influence of the lower harmonics.

In der schematischen Abbildung, elektrische Abs.timmittel sind nicht eingezeichnet, ist G der Wechselstromgenerator, A der Verdopplungstransformatorsatz, B der Vervierfachungstransformatorsatz; die Mittelwicklungen führen Gleichstrom im Sinne des Epstein-Jolly-Arco-Verfahrens, welches bekanntlich die Verdopplung der Frequenz durch Gleichstromsättigung der Verdopplungstransformatoren erzielt; 'durch die derartig bewirkte Auslöschung immer je einer Wellenhälfte und durch entsprechende Schaltung der beiden zu einem Satze gehörigen Transformatoren wird in den (in der Zeichnung rechts liegenden) Sekundärspulen ein Wechselstrom doppelter Frequenz erzeugt. Durch die Anordnung der beiden Verdopplungssätze A und B erhält man also an dem mittleren Klemmenpaare die erste, an dein rechten Klemmenpaare die zweite Harmonische der am linken Klemmenpaare abzapfbaren von der Maschine direkt erzeugten Grundfrequenz.In the schematic figure, electrical partitions are not shown, G is the alternating current generator, A is the doubling transformer set, B is the quadrupling transformer set; the center windings carry direct current in the sense of the Epstein-Jolly-Arco method, which, as is well known, achieves the doubling of the frequency by direct current saturation of the doubling transformers; 'Through the cancellation of one half of the wave each time and through appropriate switching of the two transformers belonging to a set, an alternating current of double frequency is generated in the secondary coils (on the right in the drawing). The arrangement of the two doubling sets A and B gives the first harmonic on the middle pair of clamps and the second harmonic of the fundamental frequency directly generated by the machine on the left pair of clamps.
