Abstract

The equipment is for operating a relay from a high resistance energy source, for example in the mining industry where minimum battery is necessary. The energy source (1) charges a first RC circuit (5,6) through a current limiting resistor (2) which has a time constant tau 1. A second RC circuit (3,4) with a time constant tau 2, is also charged by the same high resistance source (1,2). Time constant tau 2 is 10 x tau 1. The relay (7) and switching transistor (8) together with base resistor (10) are in parallel with the capacitor (6) of the first RC circuit (5,6). When the operate switch (9) is closed, the first RC circuit charges but does not operate the relay (7) until the second RC circuit has charged to switch on the transistor (8). The fully charged capacitors (6) discharges to operate relay (7) through transistor (8). The energy source holds the relay operated.

Description

Einrichtung zur Betätigung eines RelaisDevice for actuating a relay

Die Erfindung bezieht sich auf eine Einrichtung zur Betätigung eines Relais aus einer hochohmigen Versorgungsspannungsquelle.The invention relates to a device for actuating a Relay from a high-resistance supply voltage source.

Bei Notstromversorgungen für den Bergbau besteht aus energietechnischen Gründen die Forderung, nur hochohmige Verbraucher zu verwenden. Das bedeutet, daß die Forderung besteht, bei der Ansteuerung eines Relais mit einem möglichst geringen Batteriestrom auszukommen.Emergency power supplies for the mining industry consist of energy-related Reasons the requirement to only use high-resistance loads. It means that there is a requirement for the control of a relay with as low a value as possible Battery power get along.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zur Betätigung eines Relais aus einer hoehohmigen Versorgungsspannungsquelle anzugeben, die dieser Forderung genügt.The invention is based on the object of a device for actuation of a relay from a high-resistance supply voltage source that this Requirement is sufficient.

Gemä2 der Erfindung wird diese Aufgabe dadurch gelost, daß zwischen den Ausgängen der Versorgungsquelle ein erster Widerstand und ein erster Kondensator, der in einer Zeit t 1 geladen wird, geschaltet ist, daß parallel zu dem Kondensator das Relais in Reihe mit einem Transistor geschaltet ist, daß parallel zu der Reihenschaltung des Widerstandes und des Kondensators ein zweiter Widerstand in Reihe mit einem zweiten Kondensator, dessen Ladezeit t 2 ein Vielfaches der Ladezeit Z 1 des ersten Kondensators beträgt, geschaltet ist, wobei der zweite Kondensator parallel zum Basisvorwiderstand des Transistors liegt.According to the invention, this object is achieved in that between the outputs of the supply source a first resistor and a first capacitor, which is charged at a time t 1, is connected that in parallel with the capacitor the relay is connected in series with a transistor that is parallel to the series circuit of the resistor and the capacitor a second resistor in series with one second capacitor, the charging time t 2 of which is a multiple of the charging time Z 1 of the first Capacitor is connected, with the second capacitor in parallel to Base resistor of the transistor is.

Die Einrichtung gemäß der Erfindung wird im nachstehend beschriebenen Ausführungsbeispiel an Hand der Zeichnung näher erläutert.The device according to the invention is described below Embodiment explained in more detail with reference to the drawing.

In der Figur ist mit 1 eine Versorgungsspannungsquelle bezeichnet. Parallel zu dieser Quelle liegen ein Begrenzungswiderstand 2, ein Schalter 9, ein Widerstand 5 und ein Kondensator 6 in Reihe. Der Kondensator 6 wird in einer Zeit t1 über den Widerstand 5 geladen. Parallel zu dem Kondensator 6 ist ein Relais 7 mit einem Transistor 8 in Reihe geschaltet.In the figure, 1 denotes a supply voltage source. A limiting resistor 2, a switch 9, is connected in parallel to this source Resistor 5 and a capacitor 6 in series. The capacitor 6 is at a time t1 charged through resistor 5. A relay 7 is parallel to the capacitor 6 connected in series with a transistor 8.

Parallel zu der Reihenschaltung des Widerstandes 5 und des Kondensators 6 ist ein weiterer Widerstand 3 in Reihe mit einem zweiten Kondensator 4 geschaltet, dessen Ladezeit k ein Vielfaches (etwa t 2 = 10 t1) der Ladezeit t1 des Kondensators 6 beträgt.In parallel with the series connection of the resistor 5 and the capacitor 6 is another resistor 3 in series with a second capacitor 4 switched, whose charging time k is a multiple (approximately t 2 = 10 t1) of the charging time t1 of the capacitor 6 is.

Parallel zu dem Kondensator 6 liegen der Basisvorwiderstand 10 des Transistors 8 und eine Zenerdiode 11 In Reihe.The base series resistor 10 of the are parallel to the capacitor 6 Transistor 8 and a Zener diode 11 in series.

Zwischen diesen beiden Elementen liegt der Basisanschluß des Transistors 8.The base connection of the transistor is located between these two elements 8th.

Die Wirkungsweise der Einrichtung ist folgende: Wird der Schalter 9 zwecks Ansteuerung des Relais 7 geschlossen, so lädt sich der Kondensator 6 in einer Zeit t 1 auf. Ein Anziehen des Relais 7 ist aber nicht möglich, da der Transistor 8 nicht leItend ist. Der Kondensator 4 lädt sich erst in einer Zeit t 2 die ein Vielfaches von t 1 beträgt, etwa t 2 = 10 t 1 auf. Nach Aufladung steuert er den Transistor 8 auf. Die Wahl von t 2 stellt sicher, daß der Kondensator 6 mit Sicherheit voll aufgeladen ist; dieser entlädt sich jetzt über das Relais 7 und den Transistor 8. Das Relais 7 zieht an. Nach der Entladung bleibt das Relais angezogen, da der zulässige Haltestrom durch geeignete Bemessung der Widerstände 5 und ? aufrechterhalten wird.The operation of the device is as follows: becomes the switch 9 closed for the purpose of controlling the relay 7, the capacitor 6 charges in a time t 1. Pulling in the relay 7 is not possible because the transistor 8 is not conductive. The capacitor 4 is only charged at a time t 2 Is a multiple of t 1, about t 2 = 10 t 1. After charging, it controls the Transistor 8 on. The choice of t 2 ensures that the capacitor 6 with certainty is fully charged; this is now discharged via the relay 7 and the transistor 8. The relay 7 picks up. After the discharge, the relay remains energized because the permissible holding current through suitable dimensioning of the resistors 5 and? maintain will.

Das Relais 7 zieht normalerweise nicht an, da auf Grund der eben genannten Bemessung nur der Haltestrom zur Verfügung steht. Die Relaisansteuerung weist, wie den bisherigen Ausführungen zu entnehmen ist, einen geringen Stromverbrauch aut.The relay 7 does not normally pick up because of the just only the holding current is available. The relay control has, as can be seen from the previous statements, a low power consumption aut.
