Abstract

Fehlstromerregte elektromagnetisch steuerbare Schaltorgane haben den Vorteil, daß sie aufgrund des Fehlstroms im Anzugs­ vorgang begünstigt sind. Wenn die den Fehlstrom erzeugende Spannungsquelle in ihrer Amplitude betriebsmäßig schwankt, wirkt sich dies in unerwünschter Weise auch auf die Fehlstromer­ regung aus. Residual current-excited electromagnetically controllable switching devices have the advantage that they are due to the fault current in the suit are favored. If the generating the fault current Voltage source fluctuates in operational amplitude, this also undesirably affects the fault current excitement.

Das Besondere an der erfindungsgemäßen Schaltungsanordnung ist, daß die Fehlstromerregung des elektromagnetisch steuerbaren Schaltorgans durch eine mit Hilfe einer Zener-Diode stabilisierte Spannung herbeigeführt wird. What is special about the circuit arrangement according to the invention is that the fault current excitation of the electromagnetic controllable switching device by means of a Zener diode stabilized tension is brought about.

Die auf die o.g. Weise im Anzugsvorgang begünstigten Schaltorgane werden zum Steuern von Energieversorgungsanlagen in Eisenbahnsicherungsanlagen eingesetzt. The on the above Favored way in the tightening process Switching devices are used to control energy supply systems used in railway safety systems.
