Description

Anordnung an Schaltern elektrisch gesteuerter Maschinen und Apparate. Zum Steuern elektrisch betriebener Fahrzeuge, Aufzüge u. dgl. werden Apparate, wie z. B. Relais, Luftdruckventile usw., benutzt, die nur sehr geringe Steuerenergien benötige und bei denen man daher zweckmäßig mit niedrigen Spannungen von etwa 5o bis ioo Volt arbeitet. Bei hoher Netzspannung braucht man hierfür eine besondere Steuerstromquelle und verwendet als solche Spannungswiderstände. Diese haben aber den Nachteil, daß sich die Spannung; am Anzapfungspunkt ändert je nach der entnommenen Stromstärke. Die letztere schwankt aber, weil auf den einzelnen Schaltstufen die Zahl; der zu erregenden Magnetspulen für die Betätigung der verschiedenen Relais wechselt.Arrangement at switches of electrically controlled machines and devices. For controlling electrically operated vehicles, elevators and the like. Apparatus such as z. B. relays, air pressure valves, etc., are used that only have very low control energies need and in which one therefore expediently with low voltages of about 5o until ioo volts works. If the mains voltage is high, you need a special one Control current source and uses voltage resistors as such. But these have the disadvantage that the tension; at the tapping point changes depending on the withdrawn Amperage. The latter fluctuates, however, because the Number; of the solenoid coils to be excited for the actuation of the various relays changes.

Der Erfindung gemäß wird nun der Spannungsabfall in allen den einzelnen Schaltstufen entsprechenden Steuerstromkreisen durch Einschalten von Ausgleichswiderständen gleich groß gehalten. Infolge des gleichen Widerstandes bleibt die Stromstärke im Steuerstromkreis bei allen mög, lichen Schaltungen immer die gleiche, und die Spannung -an der Anzapfstelle bleibt unverändert.According to the invention, the voltage drop in all of the individual Switching steps corresponding control circuits by switching on balancing resistors kept the same size. Due to the same resistance, the current strength remains in The control circuit and the voltage are always the same for all possible circuits -at the tap remains unchanged.

Eine Ausführungsform der Anordnung nach der Erfindung ist in der Abbildung wiedergegeben.An embodiment of the arrangement according to the invention is shown in the figure reproduced.

An dem Netz a liegt der Spannungswiderstand b, von dessen Anzapfungspunkt c die für die Speisung der Steuerstromkreise erforderliche reduzierte Spannung abgenommen wird. Mit den Kontaktfingern f 1, f 2 usw. sind die für die verschiedenen Schaltungen notw :en,' digen Relais r verbunden, die durch die Schaltwalze s gesteuert werden. In die durch Vermittlung der Schaltwalzenbeläge gebildeten Steuerstromkreise sind Widerstände W eingeschaltet, deren Größe so bemessen ist, daß bei jeder möglichen Schaltung stets der gleiche Steuerstrom zustande kommt.The voltage resistor b is applied to the network a, from whose tapping point c the reduced voltage required to feed the control circuits is taken. The relays r required for the various circuits are connected to the contact fingers f 1, f 2 etc. and are controlled by the shift drum s. In the control circuits formed by the switching drum linings, resistors W are connected, the size of which is dimensioned so that the same control current always comes about with every possible switching.
