Definitions
- the invention relates to an implementation for a high electrical voltage with a housing that has a flange for Attachment to an opening, wherein by the Housing a central conductor is electrically insulated, being concentric around the central conductor in the housing spaced apart conductive inserts are arranged, a dielectric is provided between the inserts.
- a central conductor is electrically insulated, being concentric around the central conductor in the housing spaced apart conductive inserts are arranged, a dielectric is provided between the inserts.
- Such an implementation is usually used to manage the Tension through a wall of an enclosure.
- An electrical capacitor is known from US-A-2,935,668, which is a dielectric formed from a polymer film, which is supported by a so-called fibrous matrix, having. Through targeted exposure to heat on the dielectric can fuse the fibrous matrix and the polymer film be that the molten polymer of the polymer film is the fibrous matrix slightly impregnated on the common contact surface.
- DE-A-44 47 571 A1 describes a dielectric of a capacitor known in which a between the capacitor surfaces oil-soaked combination of paper and plastic insert provided is. Such a dielectric is also called a mixed dielectric designated. Such dielectrics are also made JP-A-52/64654 A, JP-A-55/151322 A and from "Research Disclosure", September 1983, No. 23325.
- the invention has for its object to carry out to indicate a high electrical voltage that is simple and is time-saving to manufacture.
- the combination advantageously has only a small proportion of water because it is made of plastics contain only very small amounts of water. This low water content in the combination can be special can be removed easily and quickly since water is added Plastic materials are essentially surface-bound is. With cellulose fibers, however, the water is in the material tied itself so that it only dehumidifies very slowly can be.
- the in the manufacture of the invention The necessary dehumidification time can be carried out if necessary be reduced to one tenth of the original time.
- the Combination can also be used because of its electrical effect Dielectric are referred to.
- the plastic is polypropylene or polyester, Polycarbonate, polyimide, polyvinylidene fluoride (PVDF) or polystyrene is used. So the combination points very good electrical properties, while at the same time also good processability due to the respective material properties of the plastic.
- Gas or oil is preferably used as the insulating medium. This insulation are available as standard, tried and tested in practice and therefore allow easy manufacture of the Execution.
- the combination of film and nonwoven advantageously has one Thickness between 20 and 150 ⁇ m. These thicknesses have become Try proved to be particularly cheap, being good electrical Properties with good processability were achieved.
- the film and the flow can be a common structural unit in the Form the meaning of a sandwich structure. So that's the manufacture performing very high for a high voltage.
- the unit is also for a folding arrangement, e.g. a folding capacitor, can be used.
- the two layers the assembly can also be glued or welded together his.
- the inserts are preferably made of aluminum. In order to is a lightweight structure, with a very good workability is given. It also serves as an insulating agent with advantage gas or oil.
- the conductive inserts and the combination are advantageously wrapped around the central conductor.
- a so-called winding arrangement is formed, which can be produced particularly easily using known winding techniques.
- This winding arrangement has a first and a second conductive insert in winding technology in a housing, one or more foils and a nonwoven made of plastic being provided as a dielectric between the inserts, and the housing being filled with an insulating agent.
- the winding arrangement is characterized by short throughput and drying times in production as well as good electrical properties.
- FIG. 1 shows an implementation 1 in a highly simplified form in a sectional view along its longitudinal axis.
- the Bushing 1 is a high-voltage bushing in capacitor design executed and has a housing 3, which means a flange 4 in an opening of a not shown Wall can be attached.
- the central manager should 7, on which a high voltage, e.g. of tens of thousands to hundreds of thousands of volts, is carried through the wall without rollover.
- the Housing 3 is according to the prior art, e.g. with a Porcelain body or a body made of a composite material, if necessary provided with silicone shades.
- bushing 1 has a capacitor arrangement in its housing 3 5, which is used for potential control.
- the Capacitor arrangement 5 is principally made of conductive deposits 9 formed concentrically around the central conductor 7 in Winding technology are arranged. This makes implementation 1 regarding the electrical that is developing in it Field distribution almost rotationally symmetrical. Between the inserts 9 there is not one here for spacing shown in more detail, especially as a dielectric trained, combination 11 wrapped in Figure 2 is shown and explained in more detail.
- the housing 3 can be a gas, e.g. SF6, an oil or other insulating material suitable for high voltage, have in its interior, with which the capacitor arrangement 5 is enforced.
- a gas e.g. SF6, an oil or other insulating material suitable for high voltage
- this is Construction of the capacitor arrangement 5 also for a high-voltage capacitor usable, with the corresponding electrical connections to the inserts 9 are provided would.
- FIG. 2 shows the basic structure of the special capacitor arrangement 5 with the combination serving as dielectric 11, which serve between two electrodes 9a, 9b Deposits 9a, 9b is arranged.
- the as capacitor areas acting inserts 9a, 9b are made of a capacitor film conductive material, especially a metal, e.g. an aluminum foil.
- a conductive coated plastic e.g. a graphite-coated or aluminum-coated Polypropylene plastic, conceivable.
- the combination 11 comprises at least two layers.
- the first layer is a film or sheet 13 made of plastic educated.
- the plastic is preferably used Polypropylene plastic or a polyester plastic for use.
- the thickness is about 5 to 20 microns. In attempts thicknesses of 6, 12 and 18 ⁇ m were tested, for example.
- 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 penetration medium (for example in the sense of a wick) for the insulating agent, for example gas, in particular SF 6 , or oil. 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 Be 300 microns, the fleece 15 dimensioned in this way in its thickness is that it is the balance between the total thickness and the thickness of the film 13 forms.
- a fleece with a thickness of 80 ⁇ m was successfully used for use.
- the total thickness of the combination 11 is dimensioned such that that in terms of insulation ability at least in one comparable oil-soaked paper layer according to the state of the Technology corresponds.
- the total thickness can be compared to that State of the art can of course also be lower.
- the capacitor arrangement 5 shown is preferably a winding arrangement executed. But there are also other processing methods e.g. Folding, or pressing a winding arrangement conceivable.
- the capacitor arrangement 5 can also be used for formation serve a high voltage capacitor.
- Preferred application of the details according to the invention are gas or oil-filled Capacitors or bushings in high voltage technology given.
