Description
Gekapselte Hochspannungsschaltzelle mit Druckausgleichseinrichtungen Es sind gekapselte Hochspannungsschaltzellen mit Druckausgleichseinrichtungen bekannt. Die Druckausgleichseinrichtungen können vergitterte Öffnungen für den Austritt der Lichtbogengase bzw. Lichtbogenflammen und bewegliche Verschlußklappen haben, die sich bei überdruck in der Schaltzelle öffnen und nach dem Druckausgleich selbsttätig schließen.Encapsulated high-voltage switchgear cell with pressure compensation devices Encapsulated high-voltage switchgear cells with pressure compensation devices are known. The pressure equalization devices can have barred openings for the outlet of the Arc gases or arc flames and movable flaps that have open when there is overpressure in the switching cell and automatically after pressure equalization conclude.
Um das Erlöschen der Lichtbogengase zu beschleunigen, sind gemäß der Erfindung an der öffnung bzw. in deren Nähe an sieh bekannte Lichtbogenblasorgane magnetischer oder pneumatischer Art angeordnet. Die Blasorgane können beim Auftreten eines Lichtbogens durch den dabei entstehenden überdruck zwangläufig gesteuert, d. h. in Tätigkeit gesetzt werden, was gegebenenfalls von den sich öffnenden Klappen über Ventile bewirkt werden kann.In order to accelerate the extinction of the arc gases, according to Invention at the opening or in its vicinity see known arc blowing organs arranged magnetic or pneumatic type. The blowing organs can when occurring of an electric arc is positively controlled by the overpressure created in the process, d. H. be put into action, which may be of the opening flaps can be effected via valves.
Ein Ausführungsbeispiel der Erfindung ist in den F i g. 1 bis 3 schematisch dargestellt. Von diesen zeigt F i g. 1 den allgemeinen Aufbau einer Hochspannungsschaltzelle mit oben angeordneten Druckausgleichsöffnungen und F i g. 2 und 3 die Anordnung von Blasorganen gemäß der Erfindung.An embodiment of the invention is shown in FIGS. 1 to 3 schematically shown. Of these, FIG. 1 shows the general structure of a high-voltage switchgear cell with pressure equalization openings arranged at the top and FIG. 2 and 3 the arrangement of blowing organs according to the invention.
Gemäß F i g. 1 ist die Schalteinheit 1 mit drei Druckausgleichsöffnungen 2, 3, 4 ausgerüstet. Das Aufschlagen der Klappen 5 ist durch Anschläge 6 begrenzt. Dadurch wird -erreicht, daß die heißen Lichtbogengase in Richtung 7 strömen müssen und nicht das vor der Schalteinheit stehende Personal gefährden.According to FIG. 1 is the switching unit 1 with three pressure equalization openings 2, 3, 4 equipped. The opening of the flaps 5 is limited by stops 6. It is thereby achieved that the hot arc gases must flow in the direction 7 and do not endanger the personnel standing in front of the switching unit.
Alle drei Druckausgleichsöffnungen sind durch Gitter 8 abgedeckt. In der Nähe der Gitter sind Lichtbogenblasorgane 9 angeordnet. Als Beispiel sind pneumatische Blasorgane angenommen. Sie bestehen aus Rohren 10 mit Düsen 11 (vgl. F i g. 2 und 3), die an eine Druckluft bzw. Löschgas liefernde Einrichtung angeschlossen werden können. Die Pfeile 12 zeigen die Blasrichtung an. Die Steuerung wird von den sich öffnenden Klappen 5 über Ventile 13 bewirkt (vgl. die gestrichelte Linie 14 in F i g. 3).All three pressure equalization openings are covered by grids 8. Arc blowing organs 9 are arranged in the vicinity of the grids. As an example are pneumatic blowing organs adopted. They consist of pipes 10 with nozzles 11 (cf. F i g. 2 and 3) connected to a device that supplies compressed air or extinguishing gas can be. The arrows 12 indicate the blowing direction. Control is from causes the opening flaps 5 via valves 13 (cf. the dashed line 14 in FIG. 3).
