Description
Kühleinrichtung für elektrische Schalter Die Erfindung bezieht sich auf eine Kühleinrichtung für elektrische Schalter. Cooling Device for Electrical Switches The invention relates to to a cooling device for electrical switches.
Solche Kühleinrichtungen dienen zur Kühlung von Schalter-Strombahnen, die sich aufgrund ihres Eigenwiderstandes und ihrer Übergangswiderstände erwärmen. Gekühlte Schalter können mit Strombahnen geringeren Querschnittes und kleinerer Schalterpoloberfläche gebaut werden als Schalter ohne Kühlung.Such cooling devices are used to cool switch current paths, which heat up due to their inherent resistance and their contact resistance. Cooled switches can have smaller cross-section and smaller conducting paths Switch pole surfaces are built as switches without cooling.
Bei einer bekannten Kühleinrichtung wird die in einem Flüssigkeitsschalter enthaltene FlUssigkeit durch eine Pumpe umgewälzt und somit die Kühlung der zugeordneten Strombahn erreicht.In a known cooling device that is in a liquid switch contained liquid is circulated by a pump and thus the cooling of the associated Reached the current path.
(Deutsche Patentschrift 914 404).(German patent specification 914 404).
Pumpen benötigen zu ihrem Antrieb Energie, die sich bei Anordnung der Pumpe im Schalterpol in zusätzliche Wärme umsetzt, wodurch der Wirkungsgrad der Kühlung herabgesetzt wird.Pumps require energy to drive them, and this changes when they are arranged the pump in the switch pole converts it into additional heat, which increases the efficiency the cooling is reduced.
Der Erfindung liegt die Aufgabe zugrunde, eine Kühleinrichtung ohne bewegliche Teile zu schaffen.The invention is based on the object of a cooling device without to create moving parts.
Ferner soll die Kühleinrichtung ohne zusätzliche, den Wirkungsgrad herabsetzende Verlustenergie auskommen.Furthermore, the cooling device should without additional, the efficiency get by reducing energy loss.
Das gesteckte Ziel wird bei einer Kühleinrichtung für elektrische Schalter dadurch erreicht, daß der Schalter einen von den Strombahn-Erwärmungsverlusten beaufschlagten Schwerkraft-ZwangskUhlkreislauf für ein in einem im/oder am Schalter angeordneten Raum und einem diesem nachgeordneten Kühler eingeschlossenes Verdampfungsmittel aufweist.The goal set is with a cooling device for electrical Switch achieved in that the switch one of the current path heating losses acted upon gravity forced cooling circuit for one in one in / or on the switch arranged space and this downstream cooler enclosed evaporation means having.
Das Verdampfungsmittel besteht vorzugsweise aus Trichlorfluoräthylen, Äaeisensäuremethyläther oder Dimethylsulfid.The evaporation agent preferably consists of trichlorofluoroethylene, Äaeisensäuremethyläther or dimethyl sulfide.
In zweckmäßiger Ausgestaltung des Erfindungsgegenstandes ist der im/oder am Schalter angeordnete Raum ein die Strombahn umgebender Ringraum.In an expedient embodiment of the subject matter of the invention, the im / or The space arranged at the switch is an annular space surrounding the current path.
Zwischen dem Schalter und dem Kühler ist eine Stütze angeordnet, welche zwei Ubereinanderliegende, den Ringraum mit dem Kühler verbindende Durchflußleitungen aufweist.A support is arranged between the switch and the cooler, which two overlying flow lines connecting the annulus to the cooler having.
Eine weitere zweckmäßige Ausgestaltung des Erfindungsgegenstandes besteht darin, daß der Kühler eine zur Trennung des abgekühlten Teiles vom erwärmten Teil des Verdampfungsmittels dienende Wand aufweist.Another useful embodiment of the subject matter of the invention is that the cooler is one to separate the cooled part from the heated Has part of the evaporation means serving wall.
Die Erfindung ist in der Zeichnung, welche einen Längsschnitt durch einen an einer Wand angeordneten Schalterpol zeigt, beispielsweise und rein schematisch dargestellt.The invention is in the drawing, which is a longitudinal section through shows a switch pole arranged on a wall, for example and purely schematically shown.
In einem Schalterpol 1 ist in üblicher Weise eine Strombahn 2 angeordnet. Durch ihren Eigenwiderstand und ihre Übergangswiderstände erfährt die Strombahn 2 eine Erwärmung, die sich der sie umgebenden Schaltflüssigkeit, deren Spiegel in der Zeichnung angedeutet ist, mitteilt.In a switch pole 1, a current path 2 is arranged in the usual manner. The current path experiences through its inherent resistance and its contact resistance 2 a warming, which is the surrounding switching fluid, whose mirror in the drawing is indicated, communicates.
Die Strombahn 2 ist von einem Ringraum 3 umgeben, von dem übereinander angeordnete Durchflußleitungen 4, 5 zu einem Kühler 6 führen, welcher an einer Wand 7 befestigt ist. Da der Schalter ohnehin in der Regel mit einer Stütze 8 mit der Wand verbunden wird, sind die Durchflußleitungen 4, 5 zweckmäßig in der Stütze 8 angeordnet.The current path 2 is surrounded by an annular space 3, one above the other arranged flow lines 4, 5 lead to a cooler 6, which on a wall 7 is attached. Since the switch anyway usually with a support 8 with the Wall is connected, the flow lines 4, 5 are expediently in the support 8 arranged.
Der Ringraum 3 und der Kühler 6 sind mit einem Verdampfungsmittel gefüllt. Als rerdampfungsmittel können Trichlorfluoräthylen, Ameisensäuremethyläther bzw. Dimethylsulfid verwendet werden.The annular space 3 and the cooler 6 are with an evaporation agent filled. Trichlorofluoroethylene, formic acid methyl ether can be used as evaporation agents or dimethyl sulfide can be used.
Es ist aber auch möglich, andere Verdampfungsmittel einzusetzen.But it is also possible to use other evaporation agents.
Wirkungsweise: Die Strombahn 2 erwärmt sich bei Stromführung durch ihren natürlichen Widerstand. Die Erwärmung teilt sich dem Schaltmedium mit. Dessen Wärme beaufschlagt den Ringraum 3, in welchem das darin enthaltene Mittel verdampft und auf dem Wege des geringsten Widerstandes durch die obere DurchfluB-leitung 4 in den Kühler 6 entweicht. Dort wird die aus dem Ringraum 3 entwichene Menge des verdampften Mittels kondensiert. Das spezifisch schwerere Kondensat sinkt im Kühler 6 ab und drückt das dort befindliche Verdampfungsmittel durch die untere Durchflußleitung 5 in den Ringraum 3, worauf sich der Vorgang kontinuierlich wiederholt.How it works: The current path 2 heats up when the current is carried through their natural resistance. The heating is communicated to the switching medium. Whose Heat acts on the annular space 3, in which the agent contained therein evaporates and on the path of least resistance through the upper flow line 4 escapes into the cooler 6. There, the amount of the that has escaped from the annular space 3 is evaporated agent condensed. The specifically heavier condensate sinks in the cooler 6 and presses the evaporation agent located there through the lower flow line 5 into the annular space 3, whereupon the process is repeated continuously.
Zur besseren Steuerung des Kühlkreislaufes ist im Kühler 6 eine Trennwand 9 angeordnet, die zweckmäßig zwischen den in den Kühler 6 mündenden Durchflußleitungen 4, 5 mit einem waagerechten Steg beginnt, der sich in einem senkrechten Steg fortsetzt, welcher zwischen der Kühlerfront und der Kühlerrückwand verläuft und kurz vor dem Kühlerboden endet.For better control of the cooling circuit there is a partition in the cooler 6 9 arranged, which expediently between the flow lines opening into the cooler 6 4, 5 begins with a horizontal bar, which continues in a vertical bar, which runs between the radiator front and the radiator rear wall and just before the Radiator bottom ends.
