Description
Elektrische Schaltanlage. Es sind elektrische Schaltanlagen bekannt, bei welchen Explosionsgase, die in den Öl gefässen von Ölschaltern, Transformatoren, Ölwiderständen und dergl. entstehen, durch besondere, an den betreffenden Gefässen an geschlossene Metallrohre ins Freie abgeleitet werden. Ganz besonders ist dies nötig, wenn die genannten elektrischen Objekte in ge schlossenen Räumen untergebracht sind; die Gase sich also iin Raum ansammeln und da durch Überschläge oder Explosionen herbei führen können.
Nach der Erfindung erfolgt die Gasab leitung aus den Ölgehäusen ins Freie durch Rohrleitungen, die wenigstens stellenweise durch (ohnehin in der Anlage verwendete) hohle Stromleiter gebildet sind. Dadurch wird es möglich, ohne besondere Auspuffrohrleitun gen auszukommen.
Die beiliegende Zeichnung zeigt im Quer schnitt ein Schalthaus mit einer beispiels weisen Anlage gemäss der Erfindung.
Es bedeuten 1 ein Schalthaus, 2 und 3 Olschalter, 4 einen Öltransformator, 5 eine Schutzdrosselspule, 6, 7 und 8 hohle Strom- leiter, 9 eine hohle Sammelleitung und 10 Durchführungen.
Bei dem Ölschalter 2 ist von den beiden hohlen Ableitbolzen 11 und 12 der eine, 11, an die hohle Stromleitung 6 angeschlossen, welch letztere mit einem elektrisch nicht leitenden Rohr 13, das ins Freie führt, ver bunden ist. Der Ableitbolzen 12 ist an den hohlen Stromleiter 7 angeschlossen,<B>der</B> zu der hohlen Schalterleitung S des Ölschalters 3 führt. Zwischen dem Leitungsstück 8 und der hohlen Sammelleitung 9 ist als Gaslei tung ein den Strom nichtleitendes Rohrstück 14 eingesetzt, da der auf der Spule 5 aufge wickelte Draht als Volleiter gedacht ist. Durch die hohle Sammelleitung 9 treten die Gas drücke aus der Leitung 7 bei 15 ins Freie. Die Leitung 6 ist am Transformator 4 an geschlossen und nimmt dessen Öldämpfe usw.
durch einen Rohrstutzen 16, der unter dem Transformator-Kastendeckel mündet, auf.
Electrical switchgear. There are electrical switchgear known in which explosion gases that arise in the oil vessels of oil switches, transformers, oil resistors and the like. Are diverted to the outside through special metal pipes attached to the vessels in question. This is especially necessary when the electrical objects mentioned are housed in closed rooms; the gases accumulate in the room and can cause flashovers or explosions.
According to the invention, the gas discharge takes place from the oil housings into the open air through pipelines which are formed at least in places by hollow conductors (already used in the system). This makes it possible to do without special exhaust pipes.
The accompanying drawing shows in cross section a switchgear house with an example-wise system according to the invention.
1 denotes a switchgear house, 2 and 3 oil switches, 4 an oil transformer, 5 a protective choke coil, 6, 7 and 8 hollow conductors, 9 a hollow collecting line and 10 bushings.
In the oil switch 2 of the two hollow discharge pins 11 and 12 of the one, 11, connected to the hollow power line 6, which the latter is connected to an electrically non-conductive tube 13 which leads to the outside. The discharge pin 12 is connected to the hollow current conductor 7, which leads to the hollow switch line S of the oil switch 3. Between the line piece 8 and the hollow collecting line 9, a non-conductive pipe section 14 is used as a gas line device, since the wire wound on the coil 5 is intended as a full conductor. Through the hollow manifold 9, the gas pressures come out of the line 7 at 15 into the open. The line 6 is closed on the transformer 4 and takes its oil vapors, etc.
through a pipe socket 16 which opens under the transformer box cover.
