Abstract

Die Erfindung betrifft eine mit Isolierflüssigkeit (8) ge­ füllte Kondensator-Durchführung in Freiluftausführung für elektrische Hochspannungsgeräte, insbesondere für Trans­ formatoren und Drosselspulen. The invention relates to a ge with insulating liquid (8) filled condenser bushing in outdoor version for electrical high-voltage devices, in particular for trans formers and inductors.

Mit der Erfindung wird eine wartungsarme, isolierflüs­ sigkeitsgefüllte Kondensator-Durchführung geschaffen, de­ ren Eisfreiheit auch bei schwierigen Witterungsbedingun­ gen, zum Beispiel bei hoher Windgeschwindigkeit und Tem­ peraturen unter 0 Grad Celsius gewährleistet ist, insbeson­ dere auch in der Nähe von Naßkühltürmen von Kraftwerken. Das wird erreicht, indem der isolierflüssigkeitsgefüllte In­ nenraum der Durchführung über Ein- und Austrittsöffnun­ gen (13; 14) in der Flanscharmatur (3) mit einem aus Rohren (24), Wärmeelementen (9; 11), Umgehungsleitung (22) mit Absperrorgan (23) und Umwälzpumpe (12) bestehendem Kreislaufsystem verbunden ist. With the invention, a low-maintenance, insulating flow liquid-filled condenser bushing created, de Clear ice even in difficult weather conditions conditions, for example at high wind speeds and temperatures temperatures below 0 degrees Celsius is guaranteed, in particular also near wet cooling towers of power plants. This is achieved by the insulation liquid filled In Interior of the passage through the inlet and outlet openings gene (13; 14) in the flange fitting (3) with one made of pipes (24), heating elements (9; 11), bypass line (22) with Shut-off device (23) and circulation pump (12) existing Circulatory system is connected.
