Description

Verfahren zur Angleichung der Kontaktm@,@meier bei einer Vorrichtung zur Überwachung der Druckverhältnisse in ölgefüllte@iK"äbelri an die statischen und dynamischen Druckverhältnisse der ölkabelanlage Das Hauptpatent 637 194 betrifft eines Vorrichtung zur Überwachung der Druckverhältnisse an ölgefüllten Kabeln mittels längs des Kabels verteilter, eine Anzeigevorrichtung steuernder Kontaktmanometer. Die Kontaktmanometer bestehen aus einem mit dem Kabelöl in Verbindung stehenden abgeschlossenen Gehäuse und einer im Innern des Gehäuses angeordneten gasdichten, mit elastischen Wänden versehenen Zelle, die mit Luft oder mit einem anderen Gas gefüllt ist und die einen im Innern des Gehäuses angeordneten, den Anzeigestromkreis schaltenden Kontakt betätigt.Method for aligning the contact m @, @ meier in a device to monitor the pressure conditions in oil-filled @ iK "äbelri to the static and dynamic pressure conditions of the oil cable system. The main patent 637 194 relates to a device for monitoring the pressure conditions on oil-filled cables by means of contact pressure gauges distributed along the cable and controlling a display device. The contact pressure gauges consist of one connected to the cable oil closed housing and a gas-tight inside the housing, elastic-walled cell filled with air or another gas is filled and the one arranged inside the housing, the display circuit switching contact actuated.

Die Erfindung betrifft ein Verfahren zur Angleichung der Kontaktmanometer bei einer Vorrichtung nach ' dem Hauptpatent an die statischen und dynamischen Druckverhältnisse der Ölkabelanlage. Gemäß der Erfindung wird durch ein an der elastischen gasdichten Zelle angeordnetes Rohr, das aus dem mit dem Kabelöl in Verbindung stehenden Gehäuse des Kontaktmanometers herausragt, Gas in die Zelle eingepreßt, bis der Gasdruck den für die Anschlußstelleerforderlichen Wert erreicht hat -und danach das Röhrchen gasdicht, z. B. durch Zusammendrücken und Verlöten, verschlossen.The invention relates to a method for aligning the contact pressure gauges in a device according to the main patent to the static and dynamic pressure conditions the oil cable system. According to the invention, a gas-tight to the elastic Cell arranged tube emerging from the housing communicating with the cable oil of the contact manometer protrudes, gas is pressed into the cell until the gas pressure has reached the value required for the connection point - and then the tube gastight, e.g. B. closed by pressing and soldering.

In der Zeichnung ist sein Ausführungsbei= spiel der Erfindung dargestellt. Darin ist 5 das starre Gehäuse, dessen Inneres 4 durch die öllleitung 7 mit dem Kabelinnern in Verbindung steht. 6 ist die im Innern des Gehäuses 5 angeordnete gasdichte Zelle, die beim Absinken des Druckes mittels des Kontaktes io und der Signalleitung 8 den Signalstrom einschaltet. Gemäß der Erfindung ist die gasdichte Zelle mit einem Röhrchen i i versehen, das durch die Wandung des starren Gehäuses 5 hindurchragt und zum Auffüllen und Unterdrucksetzen der gasdichten Zelle 6 dient.In the drawing, his Ausführungsbei = game of the invention is shown. In it 5 is the rigid housing, the interior of which 4 through the oil line 7 with the Connected inside the cable. 6 is arranged in the interior of the housing 5 gastight cell, which when the pressure drops by means of the contact io and the Signal line 8 turns on the signal current. According to the invention, it is gas-tight Cell with a tube i i provided through the wall of the rigid housing 5 protrudes and serves to fill and pressurize the gas-tight cell 6.

Das Verfahren nach der Erfindung hat den Vorteil, daß bei der Montage der Kontaktmanometer an Ort und Stelle der durch die verschiedene Höhenlage der Kabelstrecke entstehende statische Druck berücksichtigt werden kann, so daß alle längs der Kabelanlage verteilten Druckmanometer auf die örtlichen Verhältnisse genau einreguliert werden können.The method according to the invention has the advantage that during assembly the contact pressure gauge in place due to the different altitudes of the Static pressure arising from the cable route can be taken into account, so that all Pressure gauges distributed along the cable system to the local conditions exactly can be adjusted.
