Definitions
- a solution to this problem is inventively in an arrangement with at least two conductive surfaces, between which is a plastic non-woven fabric as a dielectric, which is impregnated with casting resin.
- a significant advantage of the arrangement according to the invention is that due to the use of a plastic nonwoven cast resin can be used as an impregnating agent, because this despite its thick liquid penetrates well into the plastic nonwoven fabric. Another important
- the conductive surfaces maintain their uniform surface and thus a uniform distance, so that the arrangement according to the invention is relatively strong electrical load.
- the inventive arrangement does not have to be enclosed in a housing, because the casting resin is firmly enclosed in the arrangement after its curing and the entire arrangement forms a compact block.
- Mention is also the advantage that compared to the use of paper in a plastic nonwoven water mainly binds only superficially, so that the water content is relatively low, which has a favorable effect on the drying time and the energy requirements for drying.
- the moisture absorption of the impregnated wicks body in damp storage is relatively low and takes place comparatively slowly. In addition, absorbed moisture is released quickly and almost completely. The low humidity also has a positive effect on the electrical and dielectric properties, such as conductivity and loss factor.
- plastic nonwoven fabrics can be used;
- plastic nonwoven fabrics can be used in which the filaments forming the nonwoven fabric are chemically bonded.
- the plastic nonwoven fabric is a thermally bonded plastic nonwoven.
- plastic nonwoven fabric advantageously consists of polyester.
- the polyester consists of continuous filaments.
- the arrangement according to the invention can be structurally designed very differently.
- it may form a plate capacitor or else be configured as a wound capacitor, in which case the conductive surfaces of metal foils or of conductive or semiconductive layers are made of a bendable carrier material.
- the plastic nonwoven fabric is band-shaped and wound to form a wound body, wherein conductive surfaces formed by foil-like metal bands are wrapped to form concentric Leitzylindern.
- the invention is further the object of proposing a simple to produce and highly electrically conductive implementation for high voltages.
- the invention provides a high-voltage bushing with a central conductor, around which are arranged concentrically spaced conductive inserts, between which there is a plastic nonwoven fabric as a dielectric, which is impregnated with cast resin.
- a fastening flange can be applied directly to the winding body, which is not possible when carrying out the method described in the opening paragraph.
- FIG. 1 shows an embodiment of a high-voltage feedthrough according to the invention
- Fig. 2 is a section through the embodiment of FIG. 1 and in
- Fig. 3 is a section through a known implementation with a dielectric made of paper and casting resin and ift shown.
- the exemplary embodiment according to FIG. 1 reveals a bushing 1, which has a central conductor 2 lying at a high voltage.
- a band-shaped, thermally bonded plastic fleece of polyester continuous filaments is applied to form a wound body 3.
- conductive surfaces in the form of foil-like metal bands are wound under the impression of concentric conductive inserts 4.
- the winding body 3 thus formed is impregnated with cast resin, so that after curing of the casting resin, a compact, stable bushing body 5 is formed;
- a plastic nonwoven fabric filled with casting resin is then present as a dielectric 6 between the conductive inserts 4.
- a flange 7 is fastened to the leadthrough body 5, with which the leadthrough 1 is fastened in the region of a hole to a grounded wall 8 of a high-voltage system, not shown ,
- Fig. 2 shows a part of a cross-section through the bushing 1 according to Fig. 1 and shows that the spaced, conductive inserts 4 have kept a uniform distance from each other and have also maintained their uniform surface structure almost, while a corresponding representation of FIG 3 for a bushing with paper and cast resin shows metal inserts 9, which are adversely affected in their surface structure to form many pointed elevations, because the electrical load capacity is considerably reduced by these peaks.

Abstract
La présente invention concerne un ensemble doté d'au moins deux surfaces conductrices (4), entre lesquelles se trouve un non-tissé en fibres synthétiques qui sert de diélectrique (6) et est imprégné de résine. La présente invention concerne en outre une traversée pour une haute tension comportant un conducteur central (2) autour duquel sont disposés, en guise de surfaces conductrices, des inserts (4) conducteurs écartés les uns des autres de manière concentrique, entre lesquels se trouve un non-tissé en fibres synthétiques qui sert de diélectrique (6) et est imprégné de résine.
