HIGH VOLTAGE SWITCHING APPARATUS AND SWITCHGEAR USING A HIGH VOLTAGE SWITCHING APPARATUS AND METHOD FOR PRODUCING A HIGH VOLTAGE SWITCHING APPARATUS

摘要

The invention relates to a high-voltage switching device with a vacuum interrupter chamber and a switchgear with a high-voltage switching device. Moreover, the invention relates to a method for producing a high-voltage switching device with a vacuum interrupter chamber. The high-voltage switching device has a housing body 1, in which a vacuum interrupter chamber 2 is provided. The vacuum switching chamber 2 has an immovable switching contact element 4 and a movable in the axial direction switching contact element 5, wherein the movable switching contact element 5 extends out of the vacuum interrupter chamber 2 and is connected via an insulating body 7 with a movable in the axial direction actuator 8. To the immovable switching contact element 4 and the movable switching contact element 5, the current path forming conductor parts 12, 13, 14 are connected. In the case of the high-voltage switching device according to the invention, a cavity 22 filled with an insulating liquid is formed in the housing body 1, the movable switching contact element 5 extending from the vacuum interrupter chamber 2 into the cavity 22 and the actuating member 8 again extending from the cavity 22 filled with insulating liquid , The high-voltage switching device is characterized in that a sealing arrangement 10 sealing the actuating member 8 relative to the housing body 1 is provided in the cavity 22 filled with insulating liquid. As a result, a reliable interruption of the load current and the short-circuit current is achieved with a relatively short isolation distance. Consequently, the high-voltage switching device can have a compact structure.
