Description

Verfahren zur Reinigung des von Isoliermittel von Einstelltransformatoren getrennten flüssigen Isoliermittels von Lastumschaltern Lastumschalter von Einstelltransformatoren sind gewöhnlich in einem mit flüssigem Isoliermittel, vorzugsweise Öl, gefüllten und abgeschlossenen Gefäß untergebracht. Beim Betrieb des Schalters entstehen durch die Schaltlichtbögen Rußpartikeln, und durch den unvermeidlichen Kontaktabbrand wird Kontaktstaub gebildet, so daß sowohl die elektrische Festigkeit als auch die Schmierfähigkeit des Isoliermittels mit der Zeit auf ein unerträgliches Maß herabgesetzt wird. Ein derartiges Isoliermittel muß zur Erhaltung der Betriebssicherheit ausgewechselt werden.Procedure for cleaning the insulating agent from adjustable transformers separate liquid insulating agent from diverter switches diverter switches from adjustable transformers are usually in one filled with a liquid isolating agent, preferably oil and closed vessel. When operating the switch are caused by the switching arcs soot particles, and the inevitable contact erosion contact dust is formed, so that both the electrical strength and the The lubricity of the isolating agent decreased to an intolerable level over time will. Such an isolating agent must be replaced to maintain operational safety will.

Es ist nun bekannt, zusätzliches, unverschmutztes Isoliermittel dadurch einzusparen, daß die im Schaltergehäuse eingeschlossene Flüssigkeitsmenge über ein mechanisch-chemisches Filter mit Hilfe einer Pumpe umgewälzt wird. Die bekannte Einrichtung hat jedoch den Nachteil, daß der Zustand des Isoliermittels regelmäßig von einer Bedienungsperson überwacht werden muß, die erforderlichenfalls die Umwälzpumpe in Betrieb setzt und nach erfolgter Reinigung wieder abstellt.It is now known to use additional, unpolluted insulating means to save that the amount of liquid enclosed in the switch housing over a mechanical-chemical filter is circulated with the help of a pump. The well-known However, the device has the disadvantage that the state of the insulating agent regular must be monitored by an operator, if necessary the circulation pump starts up and switches off again after cleaning.

Nach der Erfindung wird dieser Nachteil nun bei einem Verfahren zur Reinigung des vom Isoliermittel von Einstelltransformatoren getrennten flüssigen Isoliermittels von Lastumschaltern durch Filterung im Umlaufverfahren dadurch vermieden, daß der Umlauf des Isoliermittels in Abhängigkeit vom Verschmutzungsgrad selbsttätig gesteuert wird. Auf diese Weise wird auch eine Gefährdung des Betriebes durch menschliches Versagen weitgehend ausgeschaltet.According to the invention, this disadvantage is now in a method for Purification of the liquid separated from the insulating agent of adjustable transformers Isolating means of diverter switches avoided by filtering in the circulation process, that the circulation of the insulating agent is automatic depending on the degree of pollution is controlled. In this way there is also a human hazard to the company Failure largely eliminated.

Da die Anzahl der erforderlichen Lastumschaltungen ein Kriterium für den Grad der Verschmutzung des Isoliermittels darstellt, ist es vorteilhaft, den Stromkreis des Pumpenmotors beispielsweise über das ohnehin vorhandene Schaltungszählwerk einzuschalten.Since the number of load transfers required is a criterion for represents the degree of contamination of the insulating agent, it is advantageous to use the Circuit of the pump motor, for example, via the already existing circuit counter to turn on.

Der Verschmutzungsgrad kann auch mit Hilfe eines im Lastumschaltergehäuse eingebauten Ölprüfgerätes festgestellt werden, das bei einem bestimmten Mindestwert der Durchschlagsfestigkeit des Öles zum Ansprechen kommt, wodurch der Steuerstromkreis des Pumpenmotors geschlossen wird.The degree of pollution can also be determined with the help of a switch housing built-in oil testing device can be determined at a certain minimum value the dielectric strength of the oil comes into play, whereby the control circuit of the pump motor is closed.
