Description

Schalter, bei denen der Unterbrechungslichtbogen durch ein im Schalter selbst aus dem flüssigen oder festen Aggregatzustand sich entwickelndes Gas gelöscht TVird, besitzen den Nachteil, daß das Gas entweicht und· neu ersetzt werden muß.Switches in which the interrupting arc is switched off by an in the switch itself gas evolving from the liquid or solid state of aggregation is extinguished the disadvantage that the gas escapes and has to be replaced again.

Dieser Nachteil wird gemäß der Erfindung dadurch vermieden, daß das Löschmedium den Schalter in Gasform entnommen und an ein Adsorptionsmittel gebunden wird, worauf es unter Wärmezufuhr von dem Adsorptionsmittel wieder getrennt, in leinem Kondensator verflüssigt und in flüssiger Form einem Vorratsbehälter zugeführt wird.This disadvantage is avoided according to the invention in that the extinguishing medium the switch is removed in gaseous form and bound to an adsorbent, whereupon it is separated again from the adsorbent with the addition of heat, in a condenser liquefied and fed to a storage container in liquid form.

Die Zeichnung veranschaulicht schematisch den Gegenstand der Erfindung.The drawing illustrates schematically the subject matter of the invention.

In meiner Druckkammer 1 sind die Kontakte 2 und 3 angeordnet. Eine Eintrittsöffhung 4, die als Düse ausgebildet ist, befindet sich am unteren Teil der Druckkammer. Die Ventile 5 und 6 schließen die Druckkammer kraftschlüssig ab. Das Ventil 5 ist durch eine Leitung mit dem Behälter 7 verbunden. Derselbe besitzt einen 'elektrischen Heizkörper 8. In dem Behälter 7 befindet si,ch ein Mittel 9, z. B. aktivierte Kohle, welches zur Adsorption des aus der Druckkammer strömenden Gases dient. Aln dem Behälter 7 ist ferner das Ventil 19 angeordnet, welches in Verbindung mit einer Kondensatkühlschlange in Verbindung steht. Die Kühlschlange 10 ist an die von einer Kohlensäureflasche 11 kommende Leitung 12 angeschlossen. Zur Regelung der einströmenden Kohlensäure in die Druckkammer 1 ist ein Regelventil 13 vorgesehen. An der Düse 4 bildet sich der Kohlensäureschnee 14.The contacts are in my pressure chamber 1 2 and 3 arranged. An inlet opening 4, which is designed as a nozzle, is located located at the lower part of the pressure chamber. The valves 5 and 6 close the pressure chamber in a non-positive manner. The valve 5 is connected to the container 7 by a line. It has an 'electric Radiator 8. In the container 7 is si, ch a means 9, for. B. activated carbon, which serves to adsorb the gas flowing out of the pressure chamber. In the container 7 the valve 19 is also arranged, which is in connection with a condensate cooling coil communicates. The cooling coil 10 is connected to that of a carbonic acid bottle 11 incoming line 12 connected. To regulate the incoming Carbon dioxide in the pressure chamber 1, a control valve 13 is provided. Forms at the nozzle 4 the carbon dioxide snow 14.

Die Wirkungsweise des Schalters und die Rückgewinnung des Löschmediums ist folgende :The operation of the switch and the recovery of the extinguishing medium is as follows :

Durch die von dem Behälter 11 kommende und durch die Rohrleitung 12 und die Düse 4 und die Druckkammer 1 eintretende flüssige Kohlensäure wird der Kohlensäureschnee 14 gebildet. Derselbe gibt an die in der Druckkammer befindliche Luft Kälte ab und erzeugt durch seine Verdunstung einen beständig anwachsenden Druck. Zur Löschung des Lichtbogens ist es vorteilhaft, einen konstanten Druck in der Druckkammer vorrätig zu haben, um dann durch die durch den Lichtbogen erzeugte Drucksteigerung eine wirksamere Gasströmung, die zur Löschung des Lichtbogens dient, zu 'erhalten. Um diesen Druck konstant zu halten, ist das Ventil 5 vorgesehen, welches sich bei einem bestimmten Druck öffnet und das Gas in dein Behälter 7 'einströmen läßt. Das Ventil S ist so fein eingestellt, daß es nur das Gas in den Behälter 7 eintreten läßt, welches durch die normale Ver-By coming from the container 11 and liquid entering through conduit 12 and nozzle 4 and pressure chamber 1 Carbonic acid is formed from the carbonic acid snow 14. The same gives to those in the pressure chamber existing air from cold and creates a steadily increasing through its evaporation Pressure. To extinguish the arc, it is advantageous to have a constant pressure in the pressure chamber, in order to then create a more effective gas flow through the pressure increase generated by the arc, which is used to extinguish the arc. To keep this pressure constant To hold, the valve 5 is provided, which opens at a certain pressure and the gas flows into your container 7 ' leaves. The valve S is so finely adjusted that only the gas can enter the container 7 leaves, which is caused by the normal

dunstung des Kohlensäureschnees erzeugt wird. Bei Entstehen des Lichtbogens und der damit verbundenen Drucksteigerung schließt das Ventil 5 den Durchgang des Gases in dem Behälter 7, und das Gas strömt, die Austrittsöffnung des Kontaktes 3 bestreichend,, durch das Ventil 6 aus. Durch diese Anordnung wird die zur Löschung des Lichtbogens erforderliche Gasströmung erhalten und der Eintritt von Kohlenoxyd, welches bei der Lichtbogenbildung in geringem Maße entsteht, in dem Behälter 7 vermieden.haze of the carbon dioxide snow is generated. When the arc arises and the with it associated pressure increase, the valve 5 closes the passage of gas in the Container 7, and the gas flows, brushing the outlet opening of the contact 3, through the valve 6 off. This arrangement provides that which is necessary to extinguish the arc Preserve gas flow and the entry of carbon oxide, which occurs to a small extent during the formation of the arcing, avoided in the container 7.

In dem Behälter 7 wird das gesammelte Gas aus der Druckkammer 1 mit Hülfe der aktiven Kohle 9 adsorbiert. Bei einem genügenden Vorrat von Gas in dem Behälter 7 wird derselbe beheizt. Durch diese Heizung wird das Gas auf Druck gebracht, wodurch sich das Ventil 19 öffnet. Daraufhin gelangt das Gas aus dem Behälter 7 in die Kondensatkühlschlange 10, wird hier verflüssigt und gelangt wieder in die KohlensäurefLascbe oder in die mit ihr in Verbindung stehende Leitung 12.In the container 7, the collected gas from the pressure chamber 1 with the aid of active carbon 9 adsorbed. With a sufficient supply of gas in the container 7 is heated the same. Through this heating, the gas is brought to pressure, whereby the valve 19 opens. Thereupon arrives the gas from the container 7 into the condensate cooling coil 10 is liquefied here and arrives back into the carbon dioxide bottle or into the line connected to it 12th

Ohne an der Erfindung etwas zu verändern, könnte man natürlich an Stelle einer einzigen Druckflasche, die sowohl zur Versorgung des Schalters mit frischem Löschmedium als auch zur Wiederaufnahme des zurückgewonnenen verflüssigten Löschmediums dient, zwei getrennte Druckflaschen verwenden, von denen die eine den Schalter speist und die andere lediglich das zurückgewonnene Löschmiedium aufnimmt. Die beschriebene und abgebildete Einrichtung hat den Vorzug größter Einfachheit und Betriebssicherheit.Without changing anything in the invention, one could of course replace a single one Pressure bottle, which is used to supply the switch with fresh extinguishing medium as well as serves to resume the recovered liquefied extinguishing medium, two separate Use pressure bottles, one of which feeds the switch and the other only the recovered extinguishers records. The device described and illustrated has the merit of the greatest simplicity and operational safety.

Zur Reinigung des Kohlensäuregases von Kohlenoxyd u. dgl. kann man geeignete Vorrichtungen treffen, um dasselbe auszuscheiden.Suitable devices can be used to clean the carbonic acid gas from carbon monoxide and the like hit to get rid of the same.
