Abstract

The electronic control circuit has a high/low stage provided by resistors and a transistor. When a positive voltage is applied to the transistor base one coupled transistor is blocked, while another conducts. A capacitor discharges and the coil operates the relay. When the control voltage is removed only one transistor conducts and the capacitor discharges in the inverse direction and the relay is driven to the off state. ADVANTAGE - Provides bistable operation of relay.

Description

Die Erfindung betrifft eine elektronische Ansteuerschaltung insbesondere für Relais, Schütze und ähnliche Vorrichtungen, die einen remanenten Antrieb aufweisen.The invention relates to an electronic control circuit especially for relays, contactors and similar devices, which have a retentive drive.

Bistabile Schaltvorrichtungen in gepolter oder remanenter Ausführung weisen gegenüber solchen mit neutralem Antrieb gewisse technische und ökonomische Vorteile auf. Um jedoch diese Vorteile noch besser zur Wirkung bringen zu können, wird eine optimale elektronische Ansteuerung gebraucht. Speziell für gepolte Relais wurden die sogenannten C-Schal­ tungen entwickelt (Relaislexikon, Hans Sauer, 2. Auflage 1985 S. 215 ff). Zum Ansteuern von Remanenzrelais sind diese Schaltungen aber ungeeignet, weil sie positive und negative Ausgangsimpulse gleicher Amplitude und Breite er­ zeugen. Die remanenten Antriebe benötigen aber abgestufte Impulsleistungen beim Anziehen und Abwerfen im Verhältnis von ca. 10 : 1.Bistable switching devices in polarized or remanent Execution show compared to those with neutral drive certain technical and economic advantages. However, to to be able to bring these advantages even better, optimal electronic control is needed. The so-called C-Schal were specially developed for polarized relays developed (relay encyclopedia, Hans Sauer, 2nd edition 1985 pp. 215 ff). For controlling remanence relays these circuits are unsuitable because they are positive and negative output pulses of the same amplitude and width testify. However, the retentive drives require graded ones Pulse powers when tightening and throwing off in relation from approx. 10: 1.

Der Erfindung liegt die Aufgabe zugrunde, eine elektronische Ansteuer-Schaltung für Remanenzrelais zu schaffen, die nur während des wenige Millisekunden dauernden Einschaltvorganges Energie verbraucht. The invention has for its object an electronic Control circuit for remanence relays to create that only during the switch-on process that lasts a few milliseconds Consumes energy.  

Diese Aufgabe wird mit den im Kennzeichen des Anspruchs näher aufgezeigten Merkmalen bzw. Schritten gelöst, wobei der Auslösimpuls bzw. das Auslössignal für die Gegentakt­ stufe in ansich bekannter Weise z. B. durch ein High-Low- Ansteuerung nutzbar gemacht wird.This task is carried out in the characterizing part of the claim Features or steps detailed, solved the trigger pulse or the trigger signal for the push-pull stage in a known manner z. B. by a high-low Control is made usable.

Ein Ausführungsbeispiel der Erfindung ist im Schaltbild dar­ gestellt und im folgenden näher erläutert.An embodiment of the invention is shown in the circuit diagram provided and explained in more detail below.

Die High/Low-Ansteuerstufe besteht aus den Widerständen 9, 10 und dem Transistor 11. Wird eine positive Steuer­ spannung an die Basis des Transistors 11 gelegt, so werden die Transistoren 11 und 2 leitend, während Transistor 1 gesperrt bleibt. Der Kondensator 4 lädt sich über die Spule 5 auf und das Relais schaltet ein (High-Phase).The high / low control stage consists of resistors 9 , 10 and transistor 11 . If a positive control voltage is applied to the base of transistor 11 , transistors 11 and 2 become conductive, while transistor 1 remains blocked. The capacitor 4 charges via the coil 5 and the relay switches on (high phase).

Liegt aber an der Basis von Transistor 11 keine Steuer­ spannung mehr an, so sperren die Transistoren 11 und 2, nur Transistor 1 wird leitend. Als Folge entlädt sich der Kondensator 4 in umgekehrter Stromrichtung, wobei die Spannung an der Spule 5 entsprechend der an der Diode 6 und dem Abwerfwiderstand 7 abfallenden Spannung auf ca. 1/10 Ladespannung gehalten wird. Das Relais fällt sicher ab (Low-Phase).However, if there is no more control voltage at the base of transistor 11 , then transistors 11 and 2 are blocked, only transistor 1 becomes conductive. As a result, the capacitor 4 discharges in the opposite direction of the current, the voltage across the coil 5 being kept at approximately 1/10 charging voltage in accordance with the voltage drop across the diode 6 and the drop resistor 7 . The relay drops out safely (low phase).

Natürlich kann entsprechend den gegebenen Möglichkeiten, z. B. bei Steuer- und Regelschaltungen, die Gegentakt­ stufe auch über integrierte Schaltkreise angesteuert werden. Of course, depending on the possibilities, e.g. B. in control and regulating circuits, the push-pull stage also controlled via integrated circuits will.  

So bietet z. B. ein Timer-IC eine einfache Möglichkeit, um über seinen Rücksetzeingang, den Triggereingang oder den Schwellwerteingang die Gegentaktstufe zu steuern, wobei also Tastschalter, Startimpulse oder eine Spannungs­ steuerung verwendet werden können.So z. B. a timer IC an easy way to via its reset input, the trigger input or to control the threshold value input the push-pull stage, so where are pushbuttons, start pulses or a voltage control can be used.

Bis zu einer Stromversorgungsspannung von 5,5 V wird der Abwurfwiderstand 7 nicht benötigt, da der Spannungsabfall an der Diode 6 für den Abschaltvorgang des Remanenz-Relais ausreicht.The drop resistor 7 is not required up to a power supply voltage of 5.5 V, since the voltage drop at the diode 6 is sufficient for the switching off process of the remanence relay.
