Description

Einrichtung zur-Überwachung des Ölstandes Die Erfindung betrifft eine Einrichtung zur L`berwachung des Ölstandes in einem auf einem Durchführungsisolator angeordneten. auf Hochspannungspotential liegenden oder unter Hochspannung stehende Teile enthalten- den Las tschaltergefäf mit Hilfe ein ,--s Schwimmers, der filier eine durch ein Füh- rungsrohr hindurchgehende Stange einen Signalstromkreis schließt. Es sind ülerwachungseinrichtungen des ölstan des von el-ektr;Schell Gefüßen bekannt. hei denen der Signalstromkreis durch eine durch ein Führungsrohr hindurchgehende Stange, die mit einem Schwimmer verbunden ist. betätigt wird. jedoch ist die Anwendung solcher Schwirnineranordnungen für auf Po- tential stehende Lastschalter nicht ohne wei- teres mügl:ch. Fs ist ferner bekannt, bei auf Durchführungsisolatoren angeordneten Last- schältern .eine Schwininieranordnung so aus- zubilden, däli durch den Schwimmer ein Kün- takt beiätigt wird, der einen von einem Wandler gespeisten Signalstroinlcreis schließt. Das Ganze befriciet :ich hierbei auf Hoch- spannungspotential. \ach der Erfindung erhält man eine be- sonders zweckmäßige Anordnung in der Weise, daß die Isolierstange ain oberen Ende mit dein Schwiininer versehen ist und inner- halb eines Isoli:°rrohres sich durch das Last- .chaltergefä ß tinti den Durchführungsisolator erstreckt, wobei ihr untere: Ende an einem Kontaktstück des auf Erdpotential liegenden Signalstromes angreift. I3;-#i der erfindungs- reMäßen Ausbildung kann somit ein Nieder- spannungssignalstromkreis verwendet werden, der ciline weiteres zugänglich ist. Anderer- se:ts ist tlas 13etätigungsgestän ge einfach in] Aufbau und verläuft witterungsgeschützt im Inneren des 1,a.stsclialter"efäßes und des Durchführun-sisolators. sf) daß StA>run-en vermieden werden. Das Vbertreten des ver- unreinigt:n Lastschalteröles. in den "frans- forniatorkessel wird lief einer solchen Aus- 'Ifil#hin- de,eaün;@:@ auch sicher vermieden. Die Erfindung sei an einem .@ustüh@ungs- hc#ispiel erläutert. Die Zeichnung stellt eine Transformatordurchführtin- i dar. auf <leg eiri Lastschalter z angeordnet ist. 77r CLüer- u-achung des t "ilstandes innerhalb des T ast- schalters ist nun ani oberen Ende !leg Isolier- stange 3 ein Schwimmer d. befestigt. so claß sich mit dein Schwimmer die Isolierstange 'licl),t und senkt. Zur Führung der Isolier- stange im Isolatorinneren ist ein Isolierrohr 7 Torgesehen. Das untere Ende der Isolier- stange wirkt auf einen z«-eekniälii; au: Iso- lierstoff bestehenden Isontakthehel ; ein. der den @i@;nalstronikreis 6 betätigt. Device for monitoring the oil level The invention relates to a device for L`monitoring the oil level in one a bushing insulator arranged. lying on high voltage potential or Contains high voltage parts - the switch box with the help, - s Swimmer, who filier one through a guide support tube through a rod Signal circuit closes. There are monitoring devices of the oil level of el-ectr; known as Schell feet. called which the signal circuit through a passing through a guide tube Rod connected to a float is. is operated. however, the application is such Schwirniner arrangements for on Po- potential load switches are not easily teres mügl: ch. Fs is also known at on Bushing insulators arranged load peel off a Schwininierordnung in such a way so that the float creates an artificial clock is actuated, the one by one Converter-fed signal flow circuit closes. The whole thing is fricet: I here at high voltage potential. After the invention, one obtains a particularly expedient arrangement in the Way that the insulating rod is in the upper end is provided with your Schwiininer and half of an insulating pipe through the load .chaltergefäß tinti the bushing insulator extends, with its lower: end at one Ko ntakts Tück of at ground potential, Signal current attacks. I3; - # i of the invention Correct training can therefore result in a low voltage signal circuit can be used, the ciline is further accessible. Another- se: ts is tlas 13actuating linkage simply in] Construction and runs protected from the weather in the Inside of the 1, a.stsclialter "vessel and the Bushing isolators. sf) that StA> run-en be avoided.
