Embodiment Construction

[0025] Such as figure 1 Schematically depicted, feedthrough insulators 2 serve to separate switching chambers 1 from one another in a gas-tight and pressure-resistant manner. Also in figure 1 The electric conductor 3 which can be constituted as a solid conductor or a movable separate electrode is schematically described in , and the electrical energy usually flows via the electric conductor of one switch chamber segment through the electrodes of the through insulator to the adjacent switch chamber segment Conductor. For certain operating situations the pressure of the insulating gas is only generated from one side, as this is schematically shown by the figure 1 The symbol p in represents. This requires a high mechanical strength of the feedthrough insulator 2 .

[0026] figure 2 The schematic structure of the feedthrough insulator 2 is shown. The feedthrough insulator comprises an insulator 4 , for example made of epoxy resin, which is usually cast into a metal flange 5...

Abstract

The invention relates to a partition insulator consisting of an essentially disc-shaped insulation body, comprising a fastening flange, preferably metallic, and at least one electrode that is preferably rotationally symmetrical and that passes through said insulating body in an axial manner. The cross-section thereof, is greater in the central plane of the insulation body than in the region of the surfaces of the insulating body that are opposite each other. In order to enable said partition insulator to be used with high electric powers, and to also have high safety reserves that are adequate for load switching, and a high mechanical compressive strength with the highest possible rupture pressure, said insulator body has a thickness that reduces in all directions from the centre thereof to the outside. In order to ensure high mechanical strength, said partition insulator is fitted with electrodes and the largest cross-section in the central section thereof rests in the region of the central plane of the insulating body, and said cross-section has no point that is smaller than on the ends of the electrodes.

Description

technical field [0001] The invention relates to a feed-through insulator (Schottisolator) comprising a substantially disc-shaped insulator, possibly with a preferably metallic fastening flange, and with at least one, preferably rotationally symmetrical, electrode extending axially through the insulator, the transverse direction of which is The cross-section is larger in the center plane of the insulator than in the region of the mutually opposite surfaces of the insulator. Background technique [0002] In particular, the electrical switchgear in the high-voltage range is preferably designed as a gas-tight switchgear in order to improve the electrical properties. The spatial separation between the individual switching chambers is achieved by feed-through insulators, as described in DE 10142856 or JP 62-166719. The gas-tight feedthrough insulator allows a gas-tight separation of the gas-filled region of the switchgear from adjacent regions of the switchgear. On the one hand,...
