Description
Gegenstand der Erfindung ist ein Freistrahldruckgasschalter, bei dem die beiden Schaltkontakte in Löschköpfen angeordnet sind und beim Abschaltvo-rgang hinter Verengungen der die Kontakte ringförmig umgebenden Ausblasekanäle der Löschköpfe zurückgezogen werden. Bei diesen Schaltern treffen die aus den zylindrischen, verengten Austrittsenden der Blaskanäle austretenden Druckgasstrahlen aufeinander und behindern sich gegenseitig.The invention relates to a free jet pressure gas switch in which the two switching contacts are arranged in extinguishing heads and during the shutdown process behind constrictions of the blow-out channels of the erase heads surrounding the contacts in a ring shape be withdrawn. With these switches, the cylindrical, narrowed ones meet Exit ends of the blow channels exiting compressed gas jets on each other and hinder each other.
Erfindungsgemäß wird nun dadurch eine Verbesserung erzielt, daß die Verengungen der Ausblasekanäle zurückgesetzt im Innern der Löschköpfe angeordnet und die Ausblasekanäle vorn den Verengungen an bis zu den Austrittsenden trichterartig erweitert sind. Dadurch wird erreicht, daß die aus den beiden Löschköpfen austretenden, gegeneinandergerichteten Druckgasstrahlen divergent ausströmen. Sie behindern sich dadurch weniger. Die Blasung wird intensiver, und die Lichtbogengase werden schneller abgeführt.According to the invention, an improvement is achieved in that the Constrictions of the blow-out channels are set back and arranged inside the extinguishing heads and the blow-out channels in front of the constrictions up to the outlet ends in a funnel-like manner are expanded. This ensures that the exiting from the two extinguishing heads, opposing compressed gas jets flow out divergently. You hinder yourself therefore less. The blow becomes more intense and the arc gases become faster discharged.
Es sind zwar an sich Schalter mit trichterartig sich erweiternden Ausblasekanälen bekannt. Dabei handelt es sich aber nicht um Schalter mit zwei sich gegenüberstehenden Ausb:laselzanälen.There are actually switches with funnel-like widening Known blow-out channels. But these are not switches with two themselves opposite design: laselzanälen.
Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgegenstands.The drawing shows an embodiment of the subject matter of the invention.
In dem Löschkopf i eines Freistrahldruckgasschalters ist der Schaltstift :2 verschiebbar angeordnet. Sein Antrieb befindet sich in dem Gehäuse 3. Die mit strichpunktierten Linien angedeutete Stellung ist die Einschaltstellung. 4 ist die verengte Stelle des Gasausströmkanals 5, der sich von hier aus zu einem Trichter 6 in der gezeichneten oder einer ähnlichen, für die Ausströmung günstigen Form erweitert. Der zweite Löschkopf des Schalters, der dem Dargestellten mit seiner Ausblaseöffnung gegenübersteht, ist nicht gezeichnet. Man erkennt jedoch, daß die durch die trichterartigen Kanäle austretenden Druckgasstrahlen divergent ausströmen und sich daher weniger behindern als bei der bekannten zylindrischen Ausführung des Blaskanalendes.The switch pin is located in the erase head i of a free-jet compressed gas switch : 2 slidably arranged. Its drive is located in the housing 3. The with The position indicated by dash-dotted lines is the switch-on position. 4 is the narrowed point of the gas discharge channel 5, which from here becomes a funnel 6 expanded in the drawn or a similar form favorable for the outflow. The second erase head of the switch, which the depicted with its blow-out opening facing is not drawn. It can be seen, however, that the funnel-like Channels exiting compressed gas jets flow out divergently and therefore less hinder than in the known cylindrical design of the blow channel end.
