Description
Löschrohr für elektrische Schalter mit Lichtbogenlöschung durch Gase und Dämpfe Das Hauptpatent 66i 56t betrifft ein Löschrohr für Gasschalter mit Lichtbogenlöschung durch Gase oder Dämpfe, die durch den Unterbrechungslichtbogen selbst aus den gasabgebenden Schaltraumwandungen erzeugt werden, wobei die Wandungen aus polymerisierten Derivaten der Akrylsäure und deren Homologen bestehen.Extinguishing tube for electrical switches with arc extinguishing by gases and vapors. The main patent 66i 56t relates to an extinguishing tube for gas switches with arc extinguishing by gases or vapors emitted by the interrupting arc itself from the gas emitting Switch room walls are generated, the walls made of polymerized derivatives of acrylic acid and its homologues.
Es ist andererseits bekannt, als Aufbaustoff von Löschrohren und Füllstiften Fiber zu verwenden, das an sich für eine Gaserzeugung sehr geeignet ist, aber wesentliche Nachteile aufweist. Der eine Nachteil besteht darin, daß Fiber unter dem Ein$uß einer feuchten Atmosphäre starken, durch Quellungen bedingten Formänderungen unterworfen ist, und der andere darin, daß die Löschfähigkeit des Fibers, die an das Vorhandensein von Wasser gebunden ist, bei längerer Erwärmung durch Verdunstung stark vermindert wird. .On the other hand, it is known as a building material for extinguishing pipes and filler pens To use fiber, which in itself is very suitable for gas generation, but essential Has disadvantages. The one disadvantage is that fiber under the influence subject to strong changes in shape caused by swelling in a moist atmosphere is, and the other in that the erasability of the fiber, which indicates the presence is bound by water, greatly reduced by evaporation when heated for a longer period of time will. .
Diese Nachteile von Fiber als gasabgebendes 'Material werden gemäß der Erfindung dadurch vermieden. daß es zusammen mit Polyakrylat zum Aufbau der gasabgebenden Schaltkammerteile (Löschrohre und Füllstifte) verwendet wird, wobei die Löschfähigkeit des Gemisches wesentlich größer ist als die von Fiber bzw. Polyakrylat allein. Der- besondere Vorteil eines derartig zusammengesetzten Löschrohrwandungsstoffes besteht darin, daß durch die allseitige Umschließung des Fibers mit Polyakrylat die an das Vorhandensein von Wasser gebundene I.iischfiiliigkeit des Fibers auch bei längerer Erwärmung erhalten bleibt und andererseits Quellunget@ durch den feuchtigkeitsbeständigen Polyakrylatübergang vermieden-werden.These disadvantages of fiber as a gas emitting material are according to the invention thereby avoided. that it is used together with polyacrylate to build up the gas-emitting switching chamber parts (extinguishing tubes and filler pins) is used, whereby the extinguishing capacity of the mixture is much greater than that of fiber or polyacrylate alone. The particular advantage of such a composite extinguishing tube wall material consists in that by enclosing the fiber on all sides with polyacrylate the liquidity associated with the presence of water of Fibers are retained even after prolonged heating and, on the other hand, Swellet @ can be avoided by the moisture-resistant polyacrylate transition.
Der Löschrohrwandungsstoff wird v orteilhafterweise als Preßstoff verwendet, wobei das Fiber in gemahlenem Zustande zur Anwendung, gelangt, wodurch besonders gleichmäßige Löscheigenschaften erzielt werden. Zur Erzielung .einer besonders guten :mechanischen Festigkeit kann das Fiber auch als Schichtstoff verwendet werden.The extinguishing pipe wall material is advantageously used as a pressed material used, whereby the fiber is used in a ground state, whereby particularly uniform extinguishing properties can be achieved. To achieve .one special good: mechanical strength, the fiber can also be used as a laminate.
Der erfindungsgemäsie gasabgebende Isolierstoff ist natürlich nicht nur auf Löschrohre für Gasschalter beschränkt, sondern kann mit Vorteil bei allen solchen :elektrischen Apparaten, bei denen die Wandungen in Berührung mit dem Lichtbogen kommen und durch Gasabgabe löschend auf den Lichtbogen einwirken sollen, z: B. bei Hochspannungsausblasesicherungen, zur Verwendung belangen.The inventive gas-emitting insulating material is of course not limited only to extinguishing pipes for gas switches, but can be used with advantage for all such: electrical apparatus in which the walls are in contact with the arc and should have an extinguishing effect on the arc by emitting gas, e.g. at High voltage blowout fuses, for use.
