Description

  

      Gleichstrom-Schnellschalter.       Für automatische, elektrische Gleich  stromanlagen braucht man einen Schalter,  der bei     Kurzschluss    sehr rasch auslöst und  sich     selbsttätig    wieder einschalten kann. Be  steht der     Kurzschluss    noch bei der Wieder  einschaltung, so darf die     Auslösung    nicht von  dem     Einschaltmeahanismus    behindert sein.  



  Die vorliegende Erfindung ermöglicht  eine einfache Lösung dieser Aufgabe. Die  Zeichnung betrifft ein Ausführungsbeispiel  hierfür.  



  <B>1</B> ist ein mit dem Schalthebel<B>6</B> gelenkig  verbundener     Hagnetkern,    der einerseits     von     einem separat erregten Magnet 2 mit Spule<B>3</B>  angezogen, und festgehalten werden kann,  anderseits vom     llauptstrommagneten    4 mit  Spule<B>5</B>     beeinflussbar    ist. Die Magnetspulen<B>3</B>  und<B>5</B> sind derart gewählt,     dass    infolge der       rösseren    Anziehungskraft des Magnetes 4 bei  Überstrom der     Magnethern   <B>1</B> in die Spule<B>5</B>  gezogen, wird, wodurch der um die Achse<B>7</B>  drehbare Schalthebel<B>6</B> den Kontakt<B>8</B> öffnet.

    Um :diesen Ausschaltvorgang zu beschleu  nigen, wird der Strom in der Haltespule<B>3</B> bei  der geringsten     Abwäxtsbewegung    des Mag-         netkernes   <B>1</B> durch den Kontakt<B>9</B> unter  brochen.  



  Die Wiedereinschaltung des Kontaktes<B>8</B>  erfolgt dadurch,     dass    durch Schliessen eines  Schalters<B>10</B> der Kontakt<B>9</B> überbrückt wird.



      DC quick switch. For automatic, electrical direct current systems, you need a switch that triggers very quickly in the event of a short circuit and can switch itself on again. If the short-circuit still exists when switching on again, tripping must not be hindered by the switch-on mechanism.



  The present invention enables a simple solution to this problem. The drawing relates to an exemplary embodiment for this.



  <B> 1 </B> is a magnet core articulated to the shift lever <B> 6 </B>, which on the one hand can be attracted and held by a separately excited magnet 2 with coil <B> 3 </B>, on the other hand can be influenced by the main current magnet 4 with coil <B> 5 </B>. The magnetic coils <B> 3 </B> and <B> 5 </B> are selected in such a way that, due to the larger attraction force of the magnet 4, in the event of an overcurrent the magnetic core <B> 1 </B> enters the coil <B> 5 </B> is pulled, whereby the switch lever <B> 6 </B>, which can be rotated about the axis <B> 7 </B>, opens the contact <B> 8 </B>.

    In order to: accelerate this switch-off process, the current in the holding coil <B> 3 </B> is reduced by the contact <B> 9 </B> at the slightest shrinking movement of the magnetic core <B> 1 </B> broke.



  The reactivation of the contact <B> 8 </B> takes place in that the contact <B> 9 </B> is bridged by closing a switch <B> 10 </B>.

Claims (1)

PATENTANSPRUCH: Gleichstrom-Schnellschalter, gekennzeich net durch einen Haltemagnet, der entgegen der Wirkung eines vom Hauptstrom erregten Auslösemagnetes den Schnellschalter ge schlossen zu halten vermag. UNTERANSPRüCHE: <B>1.</B> Schalter nach Patentanspruch, dadurch ge kennzeichnet-, dass sowohl Halte- wie Aus- lösemagnet als Solenoidmagnete mit ge meinsamer Axe ausgebildet sind. 2. PATENT CLAIM: DC high-speed switch, characterized by a holding magnet which is able to keep the high-speed switch closed against the action of a trigger magnet excited by the main current. SUB-CLAIMS: <B> 1. </B> Switch according to patent claim, characterized in that both holding and release magnets are designed as solenoid magnets with a common axis. 2. Schalter nach Patentanspruch, dadurch gekennzeichnet, dass die Erregung des Haltemagnetes bei der geringsten Off- nungsbewegung des Schalters unterbro chen wird. Switch according to patent claim, characterized in that the excitation of the holding magnet is interrupted at the slightest opening movement of the switch.
