Description

Einrichtung zum Anzeigen des Druckes von Isolierflüssigkeiten elektrischer Anlagen Bei elektrischen Anlagen ist es häufig notwendig, den Druckzustand von Isolierflüssigkeiten zu überwachen. Die Neuerung betrifft eine Einrichtung, um die Drucksteigerung oder Druckminderung (oder beides) der in Behältern befindlichen Isolierflüssigkeit von elektrischen Anlagen anzuzeigen bzw. automatisch die Druckhöhe konstant zu halten. Die Einrichtung besteht aus einem Schwimmergehäuse mit einer Gasfüllung, die unter der Einwirkung des Druckes der Flüssigkeit eine Volumänderung erfährt und deren Anfangsvolumen so bemessen ist, daß bei normalem Druckzustand der Isolierflüssigkeit der Schwimmer sich beispielsweise all der Oberfläche oder an einer beliebigen anderen stelle der Flüssigkeit hält. Bei einer Druckminderung der Isolierflüssigkeit erhält dann der Schwimmer einen Auftrieb und bei Erhöhung des Druckes der Flüssigkeit einen Abtrieb. Die vom jeweiligen Druck der Flüssigkeit bewirkte Auf- und Abwärtsbewegung führt, beispielsweise durch einen am Schwimmer befestigten zweiarmigen Hebel, die Schließung oder Öffnung von elektrischen Kontakten herbei, welche eine Signalanlage oder automatisch eine Vorrichtung zur Steigerung oder Verminderung des Druckes der Isolierflüssigkeit betätigen und den Normaldruckzustand wiederherstellen. Das Ansprechen der Einrichtung beim Oberschreiten oder Unterschreiten einer g--wünschten oberen oder unteren Druckgrepze der Isolierflüssigkeit kann durch zusätzliche, beispielsweise an dtem Hebel angebrachte Gewichte eingestellt werden. Der Schwimmer kann aus einer zum Teil mit Gas gefüllten Habe bestehen, also unten offen sein, oder es kann als Schwimmer eine geschlossene gasgefüllte Dose mit membranartigen Wänden verwendet werden. Gegenüber den bisher gebräuchlichen. Kontaktmanometern hat diese Einrichtung den Vorteil, daß sie vollständig unter der Isolierflüssigkeitsoberfläche angeordne' werden kann und daher keinen äußeren Einflüssen ausgesetzt ist.Device for displaying the pressure of insulating liquids electrical Systems With electrical systems it is often necessary to check the pressure state of insulating fluids to monitor. The innovation concerns a device to increase the pressure or Pressure reduction (or both) of the insulating liquid in containers from electrical systems or to automatically keep the pressure level constant. The device consists of a float housing with a gas filling, which under the action of the pressure of the liquid experiences a change in volume and its The initial volume is dimensioned so that the insulating liquid is under normal pressure For example, the swimmer is all over the surface or at any other place the liquid holds. When the pressure is reduced, the insulating liquid is retained then the swimmer becomes buoyant and, when the pressure increases, the fluid becomes a Downforce. The upward and downward movement caused by the pressure of the liquid leads, for example, by a two-armed lever attached to the float, which Closing or opening of electrical contacts that cause a signal system or automatically a device for increasing or decreasing the pressure of the Activate the insulating liquid and restore the normal pressure condition. The response the facility when exceeding or falling below a g - desired upper or lower pressure letters of the insulating liquid can be supplemented by, for example at Weights attached to the lever can be adjusted. The swimmer can come from a property partially filled with gas, i.e. open at the bottom, or it can be used as a Schwimmer used a closed gas-filled can with membrane-like walls will. Compared to the previously used. Contact pressure gauges have this facility the advantage that they are arranged completely under the surface of the insulating liquid and is therefore not exposed to any external influences.

Die Einrichtung kann in allen denjenigen Fällen verwendet werden, in welchen es auf die Überwachung oder die Konstanthaltung eines gewünschten Druckes einer Flüssigkeit ankommt.The device can be used in all those cases in which it is necessary to monitor or maintain a desired pressure a liquid arrives.
