Wird nun bei Parallelschaltung mehrerer Gleichrichter oder von Gleichrichtern mit ändern Gleichstromquellen der Erregerstrom für die Rückstromrelais dem zu schützenden Gleichrichter selbst entnommen, so kann der Fall eintreten, dass der Erregerstrom bei Eintreten einer Rückzündung erlischt. 



  In diesem Fall würde also das   Rückstromrelais   der   rüekzündenden   Anode ohne Erregung sein und nicht richtig ansprechen.

   PATENT-ANSPRÜCHE :
1. Einrichtung zur   Unterdrückung   von Rückzündungen in Quecksilberdampfgleichrichtern durch in die einzelnen Anodenkreise eingefügte Ohmsche Widerstände, nach Patent Nr. 112299, dadurch gekennzeichnet, dass bei Parallelschaltung mehrerer Gleichrichter oder von Gleichrichtern mit andern Gleichstromquellen der Erregerstrom für die Vormagnetisierung der Rückstromrelais des zu schützenden Gleichrichters der mit ihm parallel arbeitenden fremden Gleichstromquelle entnommen wird.

 will. If, when several rectifiers are connected in parallel, or rectifiers with different direct current sources, the excitation current for the reverse current relay is drawn from the rectifier to be protected, then the case may arise that the excitation current is extinguished when a backfire occurs.



  In this case the reverse current relay of the re-igniting anode would be without excitation and would not respond correctly.
 EMI1.2
 



   In the drawing is an embodiment. of the invention, in which the excitation of the reverse current relay is carried out by the excitation current or the excitation voltage of the rectifier working in parallel with the rectifier to be protected. a and b are rectifiers working in parallel with the anodes, the cathodes and the excitation anodes e, f is a reverse current relay provided with a floating armature for the contactor of the rectifier a
