Description

  

  Spannungsabhängiges Zeitrelais für     den    selektiven     Uberstromschutz    von Leitungen.    Es hat sich gezeigt, dass das bei einem  spannungsabhängigen Relais nach dem Patent  anspruch des     Hauptpatentesvorhandene,    augen  blicklich wirkende     Höch        ststr        omrelais    vorteilhaft  mechanisch mit dem spannungsabhängigen  Relais in Verbindung gebracht wird.  



  Die beiliegende schematische Zeichnung  zeigt hierfür drei Ausführungsbeispiele, in  denen der Trieb- und der Bremsmagnet mit  <I>T,</I>     bezw.    mit<I>B,</I> der     Auslösekontakt    mit     K,     das augenblicklich wirkende     Höchststromrelais     mit<B>31</B> und die     Zahnstange    mit Z bezeich  net sind.  



  Gemäss der     Ausführungsform    der     Fig.    1  wird die Zahnstange Z des spannungsab  hängigen Relais durch den Druck einer Feder       I'    hochgehalten. Bei Höchststrom wird der  Anker des Relais     Dl    plötzlich angezogen und  die Stange Z wird freigegeben. Die Magnete  <I>T</I> und<I>B</I> sind dauernd erregt.    Bei der Ausführungsform nach     Fig.    2 wird  der Spannungskreis erst beim Ansprechen des  Relais     M    durch Kontakte     Ki    geschlossen.  Die Magnete<I>T</I> und<I>B</I> können     intermittierend     stark belastet werden.  



  Wie die Ausführungsform der     Fig.    3 zeigt,  kann der Magnet     1'61    auch mit einer Fremd  stromquelle     G    verbunden werden, deren Strom  kreis bei Kurzschluss durch ein Höchststrom  relais N geschlossen wird.



  Voltage-dependent timing relay for selective overcurrent protection of lines. It has been shown that the instantaneous maximum current relay, which is present in a voltage-dependent relay according to the patent claim of the main patent, is advantageously mechanically connected to the voltage-dependent relay.



  The accompanying schematic drawing shows three exemplary embodiments for this, in which the drive magnet and the brake magnet with <I> T, </I> respectively. with <I> B, </I> the tripping contact with K, the instantaneously operating high-current relay with <B> 31 </B> and the rack with Z.



  According to the embodiment of FIG. 1, the rack Z of the span dependent relay is held up by the pressure of a spring I '. At maximum current, the armature of relay Dl is suddenly attracted and rod Z is released. The magnets <I> T </I> and <I> B </I> are constantly excited. In the embodiment according to FIG. 2, the voltage circuit is closed only when the relay M responds through contacts Ki. The magnets <I> T </I> and <I> B </I> can be heavily loaded intermittently.



  As the embodiment of FIG. 3 shows, the magnet 1'61 can also be connected to an external power source G, whose circuit is closed by a maximum current relay N in the event of a short circuit.
