Description
Die Erfindung betrifft eine Anordnung zum Steuern von zwei Relais durch zwei Steuerkontakte eines Kontakt-Drehspulelementes mittels eines an den Steuerkontakten dieses Drehspulinstrumentes überspringenden Hochspannungsfunkens.The invention relates to an arrangement for controlling two relays by two control contacts of one Contact moving coil element by means of a jump to the control contacts of this moving coil instrument High voltage spark.
Es sind bereits Meßinstumente, vermittels welchen Schailtvorgänge ausgelöst werden können, bekanntgeworden, jedoch haben dieselben den Nachteil, daß sie zu kompliziert sowie unsicher und zu teuer sind, abgesehen davon, daß das Meßsystem im Moment der Kontaktgabe blockiert wird und somit das Meßwerk in seiner Anzeige nur bis zu dem Bereich der Kontaktgabe verwendet werden kann. Die Erfindung zeigt eine Schalteinrichtung in Verbindung mit einem Drehspulinstrument, bei welchem gemäß der Erfindung zwei vom Relaisanker des ersten Relais gesteuerte Kontakte, und zwar ein Ruhekontakt und ein Arbeitskontakt, mit je einem der Steuerkontakte des Drehspulelementes so verbunden sind, daß der mit dem Überschlag des Funkens am ersten Steuerkontakt verbundene Stromstoß den durch Remanenz gehaltenen Anker des ersten Relais zum Abfallen bringt, daß durch den hierdurch geschlossenen Arbeitskontakt der zweite Steuerkontakt über die Erregerwicklung des zweiten Relais mit der Steuerspannungsquelle verbunden ist und daß durch den Ruhekontakt des zweiten Relais die beiden Relaiswicklungen über einen Gleichrichter an einen Teil der Steuerspannung gelegt werden.Measuring instruments, by means of which switching processes can be triggered, have already become known, however, they have the disadvantage that they are too complicated as well as unsafe and too expensive apart from the fact that the measuring system is blocked at the moment of contact and thus the measuring mechanism in its display can only be used up to the area of contact. The invention shows a Switching device in connection with a moving coil instrument, in which two according to the invention contacts controlled by the relay armature of the first relay, namely a normally closed contact and a normally open contact, are each connected to one of the control contacts of the moving coil element that the one with the rollover of the spark connected to the first control contact, the armature of the held by remanence brings the first relay to drop out that the second closed by the normally open contact Control contact is connected to the control voltage source via the field winding of the second relay and that through the normally closed contact of the second relay, the two relay windings via a rectifier can be applied to part of the control voltage.
In der Zeichnung ist der Erfindungsgegenstand in der Abbildung schematisch dargestellt. A-B sind zwei
elektromagnetische Relais, deren Anker 1, 2 in der angezogenen Stellung (Bereitschaftsstellung) in an
sich bekannter Weise infolge Remanenz an den Polschuhen 3, 4 klebenbleiben. 5, 6 sind Magnetkerne mit
Wicklungen 7, 8, die über die Unterbrechungskontakte 9, 10 und den Gleichrichter 11 an der Sekundärwicklung
des Transformators 14 (Arbeitsspannung) liegen, sobald der Anker 2 abfällt. 13 ist z.B. ein
Drehspulinstrument mit Zeiger und einer an diesem vorgesehenen Elektrode 15, der zwei verstellbar an der
Skala 16 vorgesehene Elektroden 17, 18 in einem geringen Abstand gegenüberstehen. Die Elektroden 17,
18 stehen mit den am Relais A vorgesehenen Kontaktstücken 19, 20 in elektrischer Verbindung, deren
Gegenstücke 21, 22 mit den Wicklungen 7, 8 Verbindung haben. An dem Transformator 14 ist eine
weitere Wicklung 23 vorgesehen, die eine höhere Spannung abgibt. Die Wicklung 23 steht einerseits
über die Leitung 24, die Spirale 25 mit der am Zeiger befestigten Elektrode 15 in Verbindung. Die Elektrode
15 steht den Elektroden 17, 18 mit geringem Abstand (etwa 0,5 mm) gegenüber, sobald der Zeiger mit Elektrode
15 an den Gegenelektroden 17, 18 vorbeibewegt wird. Die beiden hintereinandergeschalteten Wicklun-Anordnung
zum Steuern
von zwei Relais durch zwei Steuerkontakte eines Kontakt-Drehspulinstrumentes mittels eines an den Steuerkontakten
dieses Drehspulinstrumentes
überspringenden HochspannungsfunkensIn the drawing, the subject of the invention is shown schematically in the figure. AB are two electromagnetic relays, the armatures 1, 2 of which stick in the attracted position (standby position) in a manner known per se due to remanence on the pole pieces 3, 4. 5, 6 are magnetic cores with windings 7, 8, which are connected to the secondary winding of the transformer 14 (working voltage) via the interruption contacts 9, 10 and the rectifier 11 as soon as the armature 2 drops out. 13 is, for example, a moving-coil instrument with a pointer and an electrode 15 provided thereon, which is opposed to two adjustable electrodes 17, 18 provided on the scale 16 at a small distance. The electrodes 17, 18 are in electrical connection with the contact pieces 19, 20 provided on the relay A , the counterparts 21, 22 of which are connected to the windings 7, 8 . A further winding 23 is provided on the transformer 14 which emits a higher voltage. The winding 23 is on the one hand connected to the electrode 15 attached to the pointer via the line 24, the spiral 25 . The electrode 15 faces the electrodes 17, 18 at a small distance (approximately 0.5 mm) as soon as the pointer with electrode 15 is moved past the counter-electrodes 17, 18 . The two winding arrangements connected in series for controlling
from two relays through two control contacts of a contact moving-coil instrument by means of one of the control contacts of this moving-coil instrument

gen 13, 23 des Transformators 14 geben eine hohe Spannung ab, die so gewählt ist, daß ein Funke überspringt, sobald die Elektrode 15 einer der Elektroden 17, 18 gegenübersteht.Gen 13, 23 of the transformer 14 emit a high voltage which is selected so that a spark jumps over as soon as the electrode 15 is opposite one of the electrodes 17, 18.
Die Funktion der Schalteinrichtung ist folgende: Wird z. B. die Meßwerkspule 13 über die Klemmen 26 von einem Steuerstrom durchflossen und die Elektrode 15 in die Nähe oder an der Elektrode 18 vorbeibewegt, so verursacht in demselben Moment die an den Elektroden liegende Spannung einen Funkenüberschlag, was zur Folge hat, daß durch die über den Kontakt 20, 22 und die Wicklung 7 fließende Spannung die Remanenz am Relais A aufgehoben wird und der Relaisanker 1 infolge der Federspannung 19, 20, 22 abfällt. Nach dem Abfallen des Ankers 1 wird durch das Öffnen des Kontaktes 20, 22 die an den Elektroden 15, 18 liegende Spannung unterbrochen, wogegen durch die Schließung des Kontaktes 19, 21 die Elektrode 17 an das eine Ende der Wicklung 8 gelegt und somit die Bereitschaftsstellung für die Rückschaltung des Relais A vorbereitet wird. Kehrt z. B. der Zeiger mit der Elektrode 15 infolge der Meßwertänderung in seine Ausgangsstellung 17 zurück, so springt in diesem Moment der Funke zwischen den Elektroden 15, 17 über, wodurch der über den KontaktThe function of the switching device is as follows: If z. B. the measuring mechanism coil 13 flows through the terminals 26 of a control current and the electrode 15 moves near or past the electrode 18 , so at the same moment causes the voltage applied to the electrodes a sparkover, which has the result that through the over the contact 20, 22 and the winding 7 flowing voltage, the remanence at relay A is canceled and the relay armature 1 falls due to the spring tension 19, 20, 22. After the armature 1 has dropped, the opening of the contact 20, 22 interrupts the voltage on the electrodes 15, 18 , whereas the closing of the contact 19, 21 places the electrode 17 at one end of the winding 8 and thus the standby position for the switching back of the relay A is prepared. Returns z. If, for example, the pointer with the electrode 15 returns to its starting position 17 as a result of the change in the measured value, at this moment the spark between the electrodes 15, 17 jumps over, whereby the over the contact
