Description
Spannungsteilerschaltung Für verschiedene elektrische Gebrauchsgeräce ist es erforderlich, daß sie einmal an die volle Spannung ,angeschlossen werden und zum anderen an eirne bestimmte niedrigere Spannung.Voltage divider circuit For various electrical appliances it is necessary that they are connected to full voltage once and on the other hand to a certain lower tension.
Die vorliegende Schaltung soll insbesondere zur Herabsetzung der Spannung von Lampen zur Luftschutzverdunklung dienen, die sonst mit der vorhandenen Netzspannung gespeist werden. Zu diesem Zweck ist ein Spannungsteiler mit zwei getrennten Widerständen und einem besonderen zweipoligen Umschalter vorgesehen. Dieser ermöglicht einmal, die Gebrauchsgeräte (Lampen) an die volle Netzspannung anzuschließen, ohne daß der Spannungsteiler vom Strom durchflossen wird; durch Umschalten ist der Spannungsteiler eingeschaltet, und die Gebrauchsapparate (Lampen) erhalten die verlangte niedrige Spannung.The present circuit is intended in particular to reduce the voltage of lamps for air protection darkening, which otherwise with the existing mains voltage be fed. For this purpose there is a voltage divider with two separate resistors and a special two-pole changeover switch. This enables once to connect the appliances (lamps) to the full mains voltage without the Current flows through the voltage divider; by switching is the voltage divider switched on, and the utensils (lamps) receive the required low Tension.
In der beiliegenden Zeichnung ist das Schaltbild des: Spannungsteilers dargestellti ist der Spannungsteiler mit zwei getrennten Widerständen; 2 ist der Umschalter zum Einschalten des Spannungsteilers und zum Umschalten auf die Netzspannung; 3 sind Gebrauchsgeräte, beispielsweise Glühlampen. Der Stromverlauf ist folgender: Ist der Schalter 2 auf a-a eingeschaltet, so ist der Spannungsteiler eingeschaltet, und die Gebrauchsgeräte 3 (Lampen) erhalten die verlangte niedrige Spannung. Ist der Schalter 2 auf b-b umgelegt, dann ist der Spannungsteiler ausgeschaltet, und die Gebrauchsgeräte (Lampen) erhalten die volle Netzspannung.In the accompanying drawing is the circuit diagram of the: Voltage divider The voltage divider is shown with two separate resistors; 2 is the Changeover switch for switching on the voltage divider and for switching over to the mains voltage; 3 are utility devices, such as incandescent lamps. The current flow is as follows: If switch 2 is switched on to a-a, the voltage divider is switched on, and the appliances 3 (lamps) receive the required low voltage. is the switch 2 is switched to b-b, then the voltage divider is switched off, and the appliances (lamps) receive full line voltage.
