Description

  

      Elektriselies        Zeitrelais.     



  <B>I</B>    Die     bekannten    Zeitwerke, welche bei  elektrischen Relais die Ablaufzeit bestimmen,  arbeiten infolge ihrer verhältnismässig grossen  Reibungen auch entsprechend ungenau. Sollen  diese     Ungenauigkeiten    beseitigt werden, so  muss das elektrische Drehmoment, mittelst  welchem das Zeitwerk überwunden wird,  derart gesteigert werden,     dass    das Reibungs  drehmoment gegenüber dem elektrischen Dreh  moment sehr gering wird. Dies wirkt sich  aber wiederum in einem grösseren elektrischen  Energieverbrauch aus und verteuert die Kon  struktion.  



  Ein sehr genaues Zeitrelais mit geringem  Energieverbrauch lässt sich erfindungsgemäss  bauen, wenn als Zeitwerk eine     Uhrenhemmung     benützt wird.  



  In der Zeichnung ist eine beispielsweise  Ausführungsmöglichkeit des Erfindungsgegen  standes dargestellt. Das elektrische Dreh  moment wird in diesem Falle durch einen  Elektromagneten 1 erzeugt. Wird dieser  Magnet derart elektrisch erregt, bis das durch  eine Feder 2 und einen Hebel 3 einstellbare  Drehmoment des Ankers 4 überwunden ist,    so wird der Anker 4 angezogen unter Span  nung der     Zeitwerkfeder        ä    und gleichzeitiger  Bewegung des Federhebels 6. Dadurch wird  die Feder 7 in der durch Pfeil 13 angedeuteten  Richtung über das unter Federkraft 8  schwingende Rad 9 hinweggeschnellt, und so  das unter dem Drehmoment der. Feder 5  stehende Zeitwerk angetrieben.

   Bei angezo  genem Anker 4 läuft das Zeitwerk je nach  der mittelst des Kontakthebels 10 eingestellten  Zeit ab, bis die     Auslösekontakte    11 ange  schlossen sind.  



  Bei entsprechender Wahl der Feder 5 und  des Elektromagneten 1 lässt sich beispiels  weise eine direkte mechanische Auslösung  eines Schalters erreichen, wenn dasjenige  Element des Zeitwerkes, welches das grösste  Drehmoment überträgt, zum Beispiel die  Welle 12, auf eine     Auslöseklinke    eines  Schalters einwirkt. Das elektrische     Drehrno-          ment    kann statt elektromagnetisch auch nach  elektrodynamischem, oder nach     Ferrarisprin-          zip    und dergleichen erzeugt werden, wobei  Strom, oder Spannung, oder     .Leistung    usw.  wirksam sein können.



      Elektriselies time relay.



  <B> I </B> The known timers, which determine the expiry time in electrical relays, also work correspondingly inaccurately due to their relatively large friction. If these inaccuracies are to be eliminated, the electrical torque, by means of which the timer is overcome, must be increased in such a way that the friction torque is very low compared to the electrical torque. However, this in turn results in greater electrical energy consumption and makes the construction more expensive.



  According to the invention, a very precise time relay with low energy consumption can be built if a clock escapement is used as the time mechanism.



  In the drawing, an example embodiment of the subject invention is shown. The electrical torque is generated by an electromagnet 1 in this case. If this magnet is electrically excited until the torque of the armature 4, which can be set by a spring 2 and a lever 3, is overcome, the armature 4 is attracted under tension of the timer spring and simultaneous movement of the spring lever 6 the direction indicated by arrow 13 over the swinging under spring force 8 wheel 9, and so under the torque of the. Spring 5 driven standing time mechanism.

   When the armature 4 attracted, the timer runs depending on the time set by means of the contact lever 10 until the release contacts 11 are connected.



  With an appropriate choice of the spring 5 and the electromagnet 1, for example, a direct mechanical triggering of a switch can be achieved if that element of the timer which transmits the greatest torque, for example the shaft 12, acts on a release pawl of a switch. Instead of being generated electromagnetically, the electrical rotation clock can also be generated according to the electrodynamic principle, or according to the Ferrari principle and the like, whereby current, or voltage, or power, etc., can be effective.
