Description
Es ist bekannt, in die sogenannte Löschkammer von ölschaltern ein durch den Druck, der beim Abschalten größerer Ströme in der Kammer entsteht, gesteuertes Glied einzubauen, das z. B. durch eine Feder oder eine Bruchsicherung in seiner normalen Lage gehalten wird und erst beim Auftreten eines übergroßen Druckes eine Bewegung derart ausführt, daß der Inhalt der Löschkammer ίο vergrößert wird, zu dem Zwecke, ein übermäßiges Ansteigen des Druckes zu verhindern. Um wirkungsvoll zu arbeiten, muß man diesem Glied einen sehr großen Weg freigeben, der zu einer unwirtschaftlichen Größe der Kammer und des ganzen Schalters führt. Erfindungsgemäß wird diesem Nachteil dadurch entgegengetreten, daß das bewegliche Glied nur einen kleinen Weg zurückzulegen braucht, dafür aber zusätzliche Austrittslöcher der Löschkammer 'freigibt, die den Druckausgleich zwischen dem Inhalt der Kammer und dem außerhalb befindlichen öl erlauben.It is known that the so-called extinguishing chamber of oil switches is caused by the pressure, which arises when switching off larger currents in the chamber, to install a controlled element, the Z. B. held in its normal position by a spring or a break protection device and only when an excessive pressure occurs a movement executes in such a way that the contents of the extinguishing chamber ίο is enlarged for the purpose of preventing the pressure from rising excessively. In order to work effectively, one must give this link a very large path, which leads to an uneconomical size of the chamber and the entire switch. According to the invention this disadvantage is countered in that the movable Link only needs to cover a short distance, but additional exit holes the quenching chamber 'releases the pressure equalization between the contents of the chamber and the oil located outside allow.
Dies wird nach der Zeichnung z. B. dadurch erreicht, daß ein durch die Feder F in seiner" normalen Lage gehaltener Kolben T bei dem mit der Kontakttrennung sich bildenden Druck im unteren Teil der Löschkammer nach oben bewegt wird, wobei er nach Maßgabe des von ihm zurückgelegten Weges die Ausgleichlöcher L freigibt. Aus räumlichen Gründen wird man danach streben, die Feder F so klein wie möglich zu halten. Das ist aber nur möglich, wenn sie keine KraftThis is according to the drawing z. B. achieved in that a held by the spring F in its "normal position piston T is moved upwards at the pressure that forms with the contact separation in the lower part of the arcing chamber, whereby it releases the compensation holes L according to the distance traveled by it For reasons of space, one will strive to keep the spring F as small as possible, but this is only possible if it has no force
in der Größenordnung aufzubringen hat, die 35 etwa dem Druck im unteren Teil der Kammer entspricht. Deshalb dient sie nur dazu, den Kolben T in seiner gezeichneten Normallage zu halten bzw. ihn dahin zurückzuführen. Beim Auftreten eines Druckes wird vielmehr 40 die Bewegung des Kolbens T dadurch gebremst, daß das über ihm befindliche Öl durch die entsprechend bemessenen Löcher L oder L1 ausströmen muß, so daß die Bewegung des Kolbens T nicht schlag- oder ruckartig, son- 45 dem stetig und zügig erfolgt und sich automatisch der von unten wirkenden Kraft anpaßt. has to be applied in the order of magnitude that corresponds approximately to the pressure in the lower part of the chamber. Therefore, it only serves to hold the piston T in its normal position drawn or to lead it back there. When pressure occurs, the movement of the piston T is rather braked in that the oil located above it must flow out through the appropriately sized holes L or L 1 , so that the movement of the piston T is not sudden or jerky, but rather takes place steadily and quickly and automatically adapts to the force acting from below.
