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 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. The high-voltage switching device has a housing (1) in which a vacuum switching chamber (2) is arranged. The vacuum switching chamber (2) has a fixed switching contact element (4) and a movable switching contact element (5) movable in axial direction, wherein the movable switching contact element (5) extends from the vacuum switching chamber (2) and It is connected to an actuating mechanism (8) movable in the axial direction via an insulator (7). Conductor portions (12, 13, 14) forming current paths are connected to the fixed switching contact element (4) and the movable switching contact element (5). In the high-voltage switchgear according to the invention, a hollow space (22) filled with an insulating liquid is designed in the housing (1), wherein the movable switching contact element (5) extends from the vacuum switching chamber (2) into the hollow space (22), and the actuating mechanism (8) extends from the hollow space (22) filled with insulating liquid. The high-voltage switchgear is characterized in that a sealing device (10) is arranged in a hollow space (22) filled with an insulating liquid, sealing the actuating mechanism (8) relative to the housing (1). Reliable interruption of load currents and short-circuit currents is thereby achieved with relatively short insulation distances. Therefore, the high-voltage switchgear 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...
