Definitions
- the invention relates to a bushing for a high electrical voltage.
- a bushing for a high electrical voltage.
- Such a bushing is usually used to guide the voltage through a wall of a housing.
- Dielectrics are used for capacitors, which must also have particularly good electrical insulation properties.
- An electrical capacitor is known from US Pat. No. 2,935,668, which has a dielectric formed from a polymer film which is carried by a so-called fibrous matrix.
- the fibrous matrix and the polymer film can be fused so that the molten polymer of the polymer film slightly impregnates the fibrous matrix on the common contact surface by targeted heat action on the dielectric.
- a dielectric of a capacitor in which an oil-soaked combination of paper and plastic insert is provided between the capacitor surfaces.
- Such a dielectric is also referred to as a mixed dielectric.
- Such dielectrics are also known from JP-52/64654 A, JP-55/151322 A and from "Research Disclosure", September 1983, No. 23325.
- the invention has for its object to provide a bushing for a high electrical voltage that is simple and time-saving to manufacture.
- the task is solved with a bushing for a high electrical voltage with a housing which has a flange for fastening to an opening.
- a central conductor is guided through the housing in an electrically insulated manner, wherein conductive inserts spaced apart from one another are arranged in the housing concentrically around the central conductor,
- a combination comprising at least one layer of film and one layer of nonwoven is provided between the inlays, the combination comprising a layer of film and a layer of nonwoven having a thickness of between 20 and 300 ⁇ m,
- the film and the nonwoven are each made of plastic, and - The housing is filled with an insulating agent that penetrates the combination.
- the combination advantageously has only a low water content, since it is formed from plastics, which usually only contain very small amounts of water. This small amount of water in the combination can be removed particularly simply and quickly, since water is essentially surface-bound in plastic materials. In the case of cellulose fibers, however, the water is bound in the material itself, so that it can only be dehumidified very slowly.
- the dehumidification time required in the production of the implementation according to the invention can, if appropriate, increase to 3 a tenth of the original time can be reduced.
- the combination can also be called a dielectric due to its electrical effect.
- polypropylene or polyester, polycarbonate, polyimide, polyvinylidene fluoride (PVDF) or polystyrene is used as the plastic.
- the combination thus has very good electrical properties, and at the same time also has good processability due to the respective material properties of the plastic.
- Gas or 01 is preferably used as the insulating material. These insulating materials are available as standard, have been tried and tested in practice and therefore allow the bushing to be manufactured easily.
- the combination of film and nonwoven advantageously has a thickness between 20 and 150 ⁇ m. These thicknesses have proven to be particularly favorable in experiments, with good electrical properties being achieved with good processability.
- the film and the flow can form a common structural unit in the sense of a sandwich structure. This makes it very easy to manufacture the bushing for a high electrical voltage.
- the unit is also for a folding arrangement, e.g. a folding capacitor, can be used.
- the two layers of the assembly can also be glued or welded together.
- the inserts are preferably made of aluminum. This provides a structure with a low weight, with very good workability.
- gas or 01 is used as an insulating agent.
- the conductive inserts and the combination are advantageously wrapped around the central conductor.
- a so-called 4 called winding arrangement formed, which is particularly easy to manufacture with known winding techniques.
- This winding arrangement has a first and a second conductive insert m winding technology in a housing, one or more foils and a nonwoven made of plastic being provided between the inserts as a dielectric, and the housing being filled with an insulating agent.
- the winding arrangement is characterized by short throughput and drying times during manufacture and by good electrical properties.
- the combination of materials has only a low water content and has a large storage volume for an insulating agent.
- Figure 1 shows in a greatly simplified form a bushing 1 in a sectional view along its longitudinal axis.
- Bushing 1 is designed as a high-voltage bushing m capacitor design and has a housing 3 which can be fastened by means of a flange 4 m to an opening of a wall, not shown in more detail.
- Housing 3 is according to the prior art, e.g. with a porcelain body or a body made of a composite material, possibly provided with silicone shades.
- the bushing 1 m in its housing 3 has a capacitor arrangement 5 which is used for potential control.
- the capacitor arrangement 5 is in principle formed by conductive inserts 9, which are arranged concentrically around the central conductor 7 m winding technology.
- the bushing 1 is in relation to the electrical m that it forms
- the housing 3 can be a gas, e.g. SF6, an 01 or another insulating material suitable for high voltage, have in its interior with which the capacitor arrangement 5 is also penetrated.
- this structure of the capacitor arrangement 5 can also be used for a high-voltage capacitor, the corresponding electrical connections on the inserts 9 having to be provided for this purpose.
- FIG. 2 shows the basic structure of the special capacitor arrangement 5 with the combination 11 serving as a dielectric, which is arranged between two inserts 9a, 9b serving as electrodes 9a, 9b.
- the inserts 9a, 9b which act as capacitor areas are designed as capacitor foils made of a conductive material, in particular of a metal, for example an aluminum foil.
- a conductive coated plastic 6 In special cases, the use of a conductive coated plastic 6
- Fabric e.g. a graphite-coated or aluminum-coated polypropylene plastic, conceivable.
- the combination 11 comprises at least two layers.
- the first layer is designed as a film or foil 13 made of plastic.
- a polypropylene plastic or a polyester plastic is preferably used as the plastic.
- the thickness is about 5 to 20 ⁇ m. In tests, for example, thicknesses of 6, 12 and 18 ⁇ m were tested.
- the second layer is a fleece 15 made of plastic.
- this has the task of producing a total thickness of the combination 11 and, on the other hand, of serving as a receiving space or penetrating medium (for example in the sense of a wick) for the insulating agent, for example gas, in particular SF 6 , or 01. It therefore has a certain porosity. For example, it can also be formed by fibers.
- the total thickness of the combination 11 should be less than
- the fleece 15 m is dimensioned such that it forms the balance between the total thickness and the thickness of the film 13. For example, a fleece with a thickness of 80 ⁇ m was successfully used in a special test.
- the total thickness of the combination 11 is dimensioned such that it corresponds at least to a comparable oil-impregnated paper layer in accordance with the prior art with regard to insulating ability.
- the total thickness can of course also be less than in the prior art.
- the capacitor arrangement 5 shown is preferably designed as a winding arrangement. However, other processing methods, for example folding or pressing a winding arrangement, are also conceivable.
- the capacitor arrangement 5 can also be used to form a high-voltage capacitor. Preferred arrival 7
