Abstract

The voltage dependent switching relay is intended for making latch of a high-voltage power circuit breaker, and has an adjustment capability for correction of its response value. A parallel arrangement of two variable resistors with independent adjustment is connected in series with the relay coil. A parallel connection of a capacitor with a summation current contact for opening of the relay contact set is connected in series with one of the resistors. This arrangement makes the adjustment for correction of the response value unnecessary when the relay monitors the control voltage of the circuit breaker used e.g. in a motor drive.

Description

Die Erfindung betrifft ein spannungsabhängig schaltendes Relais. Sie bezieht sich insbesondere auf solche Relais der vorgenannten Art, die als Einschaltsperre eines Hochspannungs-Leistungsschalters eine Schalterbetätigung bei unzureichender Steuerspannung verhindern sollen. Für diesen Fall sollen der Ansprechwert der Spannung wie auch der Abfallwert fein und möglichst unabhängig voneinander einstellbar sein.The invention relates to a voltage-dependent switching relay. In particular, it relates to such Relays of the aforementioned type, which act as a switch lock for a high-voltage circuit breaker should prevent if the control voltage is insufficient. In this case, the response value should be the voltage as well as the dropout value can be finely adjusted and as independently as possible from each other.

Die für spannungsabhängig schaltende Relais üblicherweise vorgesehene Stellmöglichkeit zur Korrektur des Ansprechwertes ändert die zur Bewegung des Ankers notwendige Kraft So kann man z. B. die Kraft einer den Anker in Abfallrichtung bewegenden Feder stetig oder in Stufen einstellen. Dies beeinflußt jedoch nicht nur den Ansprech-, sondern auch den Abfallwert. Die für eine Einstellung erforderlichen Arbeiten sind deshalb umständlich und zeitraubend, wenn für beide Werte enge Grenzen einzuhalten sind.The adjustment option usually provided for voltage-dependent switching relays for correction the response value changes the force required to move the armature. B. the Adjust the force of a spring that moves the armature in the direction of fall continuously or in steps. This affects however, not only the response value, but also the dropout value. The work required for a recruitment are therefore cumbersome and time-consuming if narrow limits have to be adhered to for both values.

Die Erfindung hat das Ziel, die aufwendige mechanische Justierung zur Korrektur des Ansprechwertes eines spannungsabhängig schaltenden Relais überflüssig zu machen. Erfindungsgemäß gelingt das dadurch, daß in Reihe mit der Relaisspule die Parallelschaltung von zwei unabhängig voneinander stellbaren Widerständen liegt und daß mit dem einen Widerstand die Parallelschaltung aus einem Kondensator und einem Öffner des Relaiskontaktsatzes in Reihe geschaltet ist.The aim of the invention is the complex mechanical adjustment for correcting the response value to make a voltage-dependent switching relay superfluous. According to the invention this is achieved by that in series with the relay coil the parallel connection of two independently adjustable resistors lies and that with a resistor, the parallel connection of a capacitor and a NC contact of the relay contact set is connected in series.

Ein Ausführungsbeispiel der Erfindung wird an Hand der beiliegenden Figur beschrieben.An embodiment of the invention is described with reference to the accompanying figure.

Das als Einschaltsperre verwendete spannungsab-182 The voltage cut-off 182

hängig schaltende Relais 1 ist mit seiner Magnetspule 2 an die Spannung U zwischen den Klemmen 3 und 4 gelegt Mit der Spule 2 ist die Parallelschaltung von zwei Stellwiderständen 6 und 7 in Reihe geschaltet Mit dem Widerstand 6 liegt ferner die Parallelschaltung aus einem Kondensator 8 und einem Öffner 9 in Reihe, der zum Kontaktsatz des Relais 1 gehörtpending relay 1 is connected to the voltage U between terminals 3 and 4 with its magnet coil 2 NC contact 9 in series, which belongs to the contact set of relay 1

Das Relais 1 soll überwachen, daß die Spannung U, die als Steuerspannung eines Hochspannungs-Leistungsschalters z. B. für einen Motorantrieb verwendet wird, für eine sichere Schalterbetätigung ausreicht Deshalb soll es bei einem bestimmten Mindestwert der Spannung seinen im einzelnen nicht dargestellten Kontaktsatz betätigen.The relay 1 is to monitor that the voltage U, which is used as the control voltage of a high-voltage circuit breaker z. B. is used for a motor drive, is sufficient for a safe switch actuation.

Beim Anlegen der Spannung U an die Klemmen 3 und 4 fließt durch die Relaisspule 2 die Summe der Ströme h und h, die durch die Widerstände 6 und 7 beeinflußt werden kö:inen. Wenn der Summenstrom ausreicht, den Anker des Magneten anzuziehen, öffnet der Kontakt 9. Der Kondensator 8 hält jedoch den Stromfluß noch eine gewisse Zeit aufrecht, so daß der Anker mit Sicherheit vollständig anziehen kann.When the voltage U is applied to the terminals 3 and 4, the sum of the currents h and h, which can be influenced by the resistors 6 and 7, flows through the relay coil 2. When the total current is sufficient to attract the armature of the magnet, the contact 9 opens. The capacitor 8, however, maintains the flow of current for a certain time so that the armature can definitely attract completely.

Nach dem Anziehen hält die Spule 2 den Anker bei einem geeigneten Verhältnis des Widerstandes 7 zum Widerstand 6 auch dann fest, wenn der Öffner 9 den Strom /t unterbrochen hat, weil der Abfalls« rom eines Relais kleiner als der Ansprechstrom ist Aus diesem Grunde können bei der Erfindung Ansprech- und Abfallspannung in weiten Grenzen unabhängig voneinander eingestellt werden.After tightening, the coil 2 holds the armature at a suitable ratio of the resistance 7 to Resistance 6 is fixed even when the break contact 9 has interrupted the current / t because the drop «rom a Relay is smaller than the response current. For this reason, response and dropout voltages can be used with the invention can be set independently of one another within wide limits.

Beim Einsteilen wird erst der Widerstand 7 so weit variiert, daß das Abfallen bei der gewünschten Spannung erfolgt Dann stellt man mit dem Widerstand 6 den gewünschten Ansprechwert der Spannung ein. Im vorliegenden Fall soll der Ansprechwert 82% der Nennspannung und der Abfallwert 65% der Nennspannung betragen.When setting up, the resistance 7 only becomes that far varies so that the drop occurs at the desired voltage. Then set the resistor 6 the desired response value of the voltage. In the present case, the response value should be 82% of the Nominal voltage and the dropout value are 65% of the nominal voltage.

Bei einen beim Versuchen bewährten spannungsabhängig schaltenden Relais als Spannungsmeßglied einer Einschal'sperre für einen Hochspannungs-Leistungsschalter für 10 kV, dessen Steuerspannung 220VoIt Gleichspannung betragen hat, konnte für die Relaisspule eine genaue Einstellung mit einem Kapazitätswert C = 10 μΡ für den Kondensator 8 bei Widerstandswerten von 15 Kiloohm für den Widerstand 6 und 40 Kiloohm für den Widerstand 7 erhalten werden.In a voltage-dependent switching relay that has proven itself in tests as a voltage measuring element Switch-on lock for a high-voltage circuit breaker for 10 kV, the control voltage of which is 220VoIt DC voltage, a precise setting with a capacitance value could be made for the relay coil C = 10 μΡ for the capacitor 8 for resistance values of 15 kilohms for resistor 6 and 40 kilohms for resistor 7 can be obtained.
