Description
Anschluß von Schwachstromsignalapparaten an Starkstromnetze mit Hilfe eines nach Druck der Signaltaste ansprechenden elektromagnetischen Spannungsteilers. Die Erfindung bezieht sich auf den Anschluß von Schwachstromzeichengebern an Starkstromnetze. Sie sorgt dafür, daß die Elektromagnete der Zeichengeber durch eine sie steuernde Vorrichtung zugleich nur den Strom empfangen, der für ihren Betrieb nötig ist. Diese Vorrichtung kann beliebig vielen Zeichengebern, z. B. Weckern, gemeinsam sein. Der übliche Unterbrecher der Zeichengeber kann kurzgeschlossen oder entfernt werden.Connection of low-voltage signaling devices to high-voltage networks with the help an electromagnetic voltage divider that responds when the signal button is pressed. The invention relates to the connection of low-voltage signal generators to high-voltage networks. It ensures that the electromagnets of the signal generator are controlled by one of them Device at the same time only receive the electricity that is necessary for its operation. These Device can have any number of signal generators, e.g. B. alarm clocks, be together. Of the The usual breaker of the signal generator can be short-circuited or removed.
Die Zeichnung ist ein Schema eines Ausführungsbeispieles der Erfindung.The drawing is a schematic of an embodiment of the invention.
Als Zeichengeber sind 'Wecker i angedeutet, zu denen je eine Stromschlußtaste a gehört. Die Wecker haben die üblichen Elektromagnete 3. Der normalerweise vorhandene Unterbr,.echer ist durch ,einen Draht 4: kurzgeschlossen. An die Weckerleitung 5 ist mittels Klemmen 6 folgende Einrichtung angeschlossen, welche die Wecker mit dem Starkstromnetz verbindet und durch Klemmen 7 an dieses gelegt ist.'Alarm clocks i are indicated as signal generators, each of which has a power supply button a heard. The alarm clocks have the usual electromagnets 3. The normally present one Interrupt, .echer is through, a wire 4: short-circuited. To the alarm clock line 5 the following device is connected by means of terminals 6, which the alarm clock with connects to the power network and is connected to it by terminals 7.
D,ne an den -`--Pol der Starkstromquelle angeschlossene Leitung 8 enthält einen Widerstand 9, der aus irgendeinem geeigneten Stoff besteht, eine Glimmlampe io und die Wicklung eines Relais i i. Dessen Anker ist stromleitend und mit der Leitung 8 verbunden. Er liegt in seiner Arbeitsstellung an zwei Kontaften 17 des Stromweges eines Widerstandes 13, der zwischen die Leitungen 8, 14 geschaltet ist. Der Widerstand 13 kann gleich dem Widerstand 9 aus irgendeinem passenden Stoff bestehen.D, ne to the -` - pole of the power source connected line 8 contains a resistor 9, which consists of any suitable material, a glow lamp io and the winding of a relay i i. Its armature is conductive and connected to line 8. In its working position it lies on two contacts 1 7 of the current path of a resistor 13 which is connected between the lines 8, 14. The resistor 13, like the resistor 9, can consist of any suitable material.
Es werde der Stromkreis eines der W elkker i durch die zugehörige Taste z geschlossen. Der bei + 7 in die Leitung 8 eintretende Starkstrom wird durch den Widerstand 9, die Glimmlampe io und die Wicklung des Relais i i so geschwächt, daß er den Elektromagneten 3 des Weckers nicht bis zum Anzug des Klöppels erregen kann. Der Anker des erregten Relais wird jedoch durch diesen, geschwächten Strom angezogen und legt sich gegen die Kontakte 12. Der bei -E- 7 eintretende Starkstrom fließt nunmehr über den Widerstand 9, die Kontakte i--" den Anker des Relais i i und den Widerstand 13 nach - 7. Der jetzt am Widerstand 13 entstehende Spannungsabfall wird zum Betätigen des Elektromagneten 3 benutzt, und zwar gleicht sich der Spannungsabfall aus über i2, Anker des Relais i1, 8, 5, 3, z, 5, 14.. Der Klöppel, des eingeschalteten Weckers schnellt also gegen die Glocke. ' Außerdeiri schließt sich das Relais i i durch das Anziehen seines Ankers kurz. Dieser schwingt infolgedessen in die gezeichnete Ruhelage zurück. Der den Elektromagneten 3 durchfließende Strom wird mithin wieder so geschwächt, daß der Klöppel abfällt. Bei fortgesetztem Schluß der Taste z zieht der geschwächte Strom den Anker des Relais i i wieder an, und das beschriebene Spiel wiederholt sich mit der bei Unterbrechern bekannten Geschwindigkeit, so daß der Wecker in der bekannten Weise ertönt.Let the circuit of one of the W elkker i through the associated Z button closed. The heavy current entering line 8 at + 7 is passed through the resistor 9, the glow lamp io and the winding of the relay i i so weakened, that he does not excite the electromagnet 3 of the alarm clock until the clapper closes can. The armature of the energized relay, however, is weakened by this current attracted and rests against contacts 12. The high current entering at -E- 7 now flows through the resistor 9, the contacts i-- "the armature of the relay i i and the resistor 13 to - 7. The voltage drop now occurring at the resistor 13 is used to operate the electromagnet 3, and that is the same the Voltage drop from via i2, armature of the relay i1, 8, 5, 3, z, 5, 14 .. The clapper, the alarm clock that is switched on rang against the bell. 'Also closes the relay i i briefly by tightening its armature. As a result, this vibrates back to the drawn rest position. The current flowing through the electromagnet 3 is thus weakened again so that the clapper falls off. With continued conclusion the button z attracts the weakened current to the armature of the relay i i again, and the game described is repeated at the speed known from interrupters, so that the alarm clock sounds in the known manner.
Bei dauernder Stromentnahme, die z. B. durch dauernden Schluß einer fehlerhaft gewordenen Taste a eintreten kann, wird das lästige Klingeln meist dadurch beseitigt, daß Papier zwischen Klöppel und Glocke geklemmt wird. Der Strorh fließt aber weiter. Folglich schnarrt das Relais i i. Eine Aufsichtsperson kann hieran erkennen, daß eine Störung vorliegt. Es macht sich also auch ein unbefugtes Entnehmen von Strom bemerkbar. Der so entnommene Strom ist überdies ungleichmäßig.With continuous power consumption, the z. B. by permanent conclusion of a If a faulty key a can occur, the annoying ringing is usually caused by it eliminates paper getting stuck between clapper and bell. The stream flows but continue. As a result, the relay buzzes i i. A supervisor can do this recognize that there is a fault. So there is also an unauthorized removal noticeable by electricity. The current drawn off in this way is also uneven.
