Description
Spannungsabhängig schaltendes Relais Die Erfindung betrifft ein spannungsabhängig schaltendes Relais.Voltage-dependent switching relay The invention relates to a voltage-dependent relay switching relay.
Sie bezieht sich insbesondere auf solche Relais der vorgenannten Art, dje als Einschaltsperre eines Hochspannungs-Leistungsschalters eine Schalterbetätigung bei unzureichender Steuerspannung verhindern solle. Für diesen Fall sollen der Ansprechwert der Spannung, wie auch der Abfallwert fein und möglichst unabhängig voneinander einstellbar sein.It relates in particular to such relays of the aforementioned type, dje a switch actuation as a switch-on lock of 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 decay value, fine and as independent of each other as possible be adjustable.
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.The one usually provided for voltage-dependent switching relays The setting for correcting the response value changes that for moving the armature necessary strength. So you can e.g.
die Kraft einer den Anker in Abfallrichtung bewegenden Feder stetig oder in Stufen einstellen. Dies beeinflußt jedoch nicht mir 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 force of a spring moving the armature in the falling direction is constant or set in steps. However, this does not affect me the response, but also the waste value. The work required for recruitment is therefore awkward 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 Ansprectlwertes 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 of a voltage-dependent switching relay unnecessary close. According to the invention this is achieved in that in series with the relay coil the parallel connection of two independently adjustable resistors lies and that with one resistor the parallel connection of a capacitor and an NC contact of the relay contact set is connected in series.
Nähere B'inzelheiten der Erfindung ergeben sich aus der folgenden Beschreibung eines in der beiliegenden Figur dargestellten AusfUhrungbeispiels.Further details of the invention emerge from the following Description of an exemplary embodiment shown in the accompanying figure.
Das als Sinschaltsperre verwendete spannungsabhängig schlltende Relais 1 ist mit seiner Nagnetspule 2 an die Spannung U zwischen den Klemmen 5 und 4 gelegt. Viit der Spule 2 ist die Parallelschaltung von zwei Stellwiderständen 6 und 7 in Reihe geschaltet.The voltage-dependent switching relay used as a switch lock 1 with its magnet coil 2 is connected to the voltage U between terminals 5 and 4. Viit of the coil 2 is the parallel connection of two variable resistors 6 and 7 in Connected in series.
Nit dem Widerstand 6 liegt ferner die Parallelschaltung aus einem Kondensator 8 und einem Öffner 9 in Reihe, der zuni Kontaktsatz des Relais 1 gehört.With the resistor 6 there is also the parallel connection of one Capacitor 8 and an 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 Hocbspannungs-Leistungsschalters z.B. für einen Motorantrieb verlzende-t wird, für eine sichere Schalterbetätigung ausreicht. Deshalb soll es bei einem bestimmten IwIindestwert 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 a high-voltage circuit breaker, e.g. for a motor drive, is is sufficient for safe switch operation. Therefore it should be with a certain Actuate the minimum value of the voltage on its contact set, which is not shown in detail.
Beim Anlegen der Spannung U an die Klemmen 3 und 4 fließt durch die Relaisspule 2 die Summe der Ströme ii und i2, die durch die Widerstände 6 und 7 beeinflußt werden können. 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 voltage U is applied to terminals 3 and 4, it flows through the Relay coil 2 is the sum of currents ii and i2 flowing through resistors 6 and 7 can be influenced. If the total current is sufficient, the armature of the magnet to attract, the contact 9 opens. However, the capacitor 8 still holds the current flow upright for a period of time so that the anchor is sure to fully tighten can.
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 il unterbrochen hat, weil der Abfallstrom 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 an appropriate one The ratio of the resistor 7 to the resistor 6 is fixed even when the opener 9 has interrupted the current il because the waste current of a relay is less than the Response current is. For this reason, response and dropout voltage can be used in the invention can be set independently of one another within wide limits.
Beim Einstellen wird erst der Widerstand 7 soweit variiert, daß das Abfallen bei der gewünschten Spannung erfolgt. Dann stellt man mit dem Widerstand 6 den gewünschten Ansprechwert der Spannung ein. Im vorliegenden Falle soll der Ansprech;ert 82 % der Nennspannung und der Abfallwert 65 O/o der Nennspannung betragen.When setting the resistor 7 is varied so far that the Drop at the desired voltage occurs. Then you face the resistance 6 enter the desired response value for the voltage. In the present case, the The response is 82% of the nominal voltage and the dropout value is 65% of the nominal voltage.
Bei einem bei Versuchen bewährten spannungsabhängig schaltenden Relais als Spannungsmeßglied einer Einschaltsperre für einen Hochspannungs-Leistungsschalter für 10 kV, dessen Steuerspannung 220 Volt Gleichspannung betragen hat, konnte für die Relaisspule eine genaue Einstellung mit einem Kapazitätsafert C = 10Xul? für den Kondensator 8 bei Widerstandswerten von 15 Kileohin für den Widerstand 6 und 40 Kiloohm für den Widerstand 7 erhalten werden. With a voltage-dependent switching relay that has proven itself in tests as a voltage measuring element of a switch-on lock for a high-voltage circuit breaker for 10 kV, the control voltage of which was 220 volts direct voltage, could for does the relay coil have an exact setting with a capacitance safe C = 10Xul? for the capacitor 8 at resistance values of 15 Kileohin for the resistor 6 and 40 kiloohms can be obtained for resistor 7.
