Embodiment Construction

[0029] figure 1 The components of the high voltage switchgear that are critical to the invention are shown, while figure 2 Only the individual components of the switching device are shown in an exploded perspective view. Mutually corresponding parts have the same reference numerals in the figures.

[0030] The high-voltage switchgear has a housing 1 comprising several parts or components, which in the normal installed position has an upper half-housing 1A and a lower half-housing 1B. Inside the upper half-housing 1A there is a vacuum switching chamber 2 with a cylindrical housing 3 which accommodates a fixed upper switching contact element 4 and a movable lower switching contact element 5 . The two switching contact elements 4 , 5 have disc contacts 4A, 5A which are located in the housing 3 of the vacuum switching chamber 2 . The closing and opening of the contacts 4A, 5A can close or interrupt the current path, that is, switch the load current and the short-circuit curren...

Abstract

The invention relates to a high-voltage switching device with a vacuum interrupter chamber and to a switching system with a high-voltage switching device. The invention also 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 interrupter chamber (2) has a stationary switch contact element (4) and a switch contact element (5) which is movable in the axial direction, the movable switch contact element (5) extending out of thevacuum interrupter chamber (2) and being connected via an insulating body (7) to an actuating member (8) which is movable in the axial direction. The conductor parts (12, 13, 14) forming the current path are connected to the stationary switch contact element (4) and the movable switch contact element (5). In the high-voltage switching device according to the invention, a cavity (22) filled with aninsulating liquid is formed in the housing body (1), the movable switch contact element (5) extending out of the vacuum interrupter chamber (2) into the cavity (22), and the actuating member (8) in turn extending out of the cavity (22) filled with insulating liquid. The high-voltage switching device is distinguished in that a sealing assembly (10), which seals the actuating member (8) with respect to the housing body (1), is provided in the cavity (22) filled with insulating liquid. This ensures reliable interruption of the load current and of the short-circuit current with a relatively shortinsulation portion. As a result, the high-voltage switching device can have a compact structure.

Description

technical field [0001] The invention relates to a high-voltage switchgear with a vacuum switching chamber and a switchgear with a high-voltage switchgear. Furthermore, the invention relates to a method for producing a high-voltage switchgear with a vacuum switching chamber. Background technique [0002] Switching devices are used in electrical networks comprising current conductors for distributing electrical energy. The switching device has a switching device which makes or breaks an electrically conductive connection between electrical contacts. High-voltage switching devices are used in high-voltage or medium-voltage networks which meet the electrical requirements for the high voltage in the high-voltage or medium-voltage network. The voltage in the high-voltage grid is generally above 52kV, and the voltage in the medium-voltage grid is usually between 1kV and 52kV. [0003] High-voltage switching devices are known which have a vacuum switching chamber in which electri...
