Definitions

  • the invention relates to an oil transformer insulation module having at least a first planar and a second adjacent and predominantly parallel layer of a mechanically strong, flat first insulating material.
  • high-voltage transformers or high-voltage chokes for example, with a rated voltage of 220kV or 380kV, a rated power of> 100MVA and a weight of 200t or higher, are usually located in an oil-filled transformer tank for insulation and cooling purposes the oil serves both insulation and improved cooling.
  • the distance of the high-voltage transformer from the inner wall of the oil tank is essentially due to isolation aspects, ie ultimately the distance of a potential-affected area to a grounded or other potential-charged area and the geometric shape of the components to be isolated from each other.
  • a minimum insulation distance may be required, which makes the oil boiler unnecessarily large or which is not available at all.
  • isolation barriers in insulating-technically particularly critical areas within the oil-filled transformer tank, by means of which the limitedly reliable insulating sections are subdivided in the oil or arranged that a maximum voltage gradient is not exceeded.
  • This offers the advantage that the oil-filled space between the transformer and boiler wall is not unnecessarily large.
  • Such barrier systems usually have solid plates made of presspan, which are arranged on a complex support structure according to the individual requirements within the transformer tank.
  • barrier systems are very inflexible and difficult to assemble and with respect to the geometries to be realized are ultimately limited to a plate shape, which possibly also only isolation technology not optimal arrangements are possible.
  • barrier systems must be dried before being installed in the transformer under heat in vacuum, which discard conventional barrier systems so that they often no longer meet the insulation requirements.
  • an oil transformer insulation module of the aforementioned type is characterized in that the first and the second layer insulation material with a third interposed, corrugated layer of a mechanically strong, flat, second insulating material connected and spaced, wherein the third Layer has lateral edges and is corrugated such that all cavities formed by the corrugated shape over the lateral edges are flooded completely with a liquid.
  • the basic idea of the invention is to use a barrier with cavities instead of a solid pressboard barrier, which are completely filled with oil during operation of the transformer.
  • Each path along a surface normal defining the shortest passageway through an oil transformer isolation module thus formed does not extend exclusively in solid insulation material, but rather the cavities are configured by the third layer waveform such that always a portion of the path also passes through oil. Due to the different Isolation capabilities of oil and solid insulating material such as pressboard in combination with their different dielectric constants and the resulting displacements of the electric field results in an overall higher insulation capacity at the same thickness.
  • a path running purely through solid insulating material follows in sections of the waveform of the third layer in an oil transformer insulation module according to the invention and is therefore obliquely longer and corresponding to the shortest path along a surface normal, so that an improved insulation capability also results in this respect.
  • an oil transformer insulation module is to be arranged within an oil tank such that the channels formed by the cavities extend in the vertical direction, ie from bottom to top. In this way, air pockets still in the channels can easily escape upwards when an oil transformer isolation module is submerged in oil. By drawing a vacuum, it is possible to remove possible air pockets particularly reliably from horizontally arranged channels formed by cavities.
  • a planar insulation barrier with a flat insulation module of a few square meters surface, which along the entire surface has a constant distance of a few millimeters, for example 10mm or 20mm, to a flat component to be insulated. Because of possible rejection of the barrier resulting variations in the distance would namely reduce the insulation capacity of the arrangement, even and especially if the distance is thereby locally larger than the desired distance.
  • the third layer is at least partially corrugated trapezoidal.
  • This provides an improved surface connectivity of the formed by the trapezoidal shape plateaus of the third corrugated layer with the adjacent planar first and second layers, which also also has a positive effect on the insulating ability of the ⁇ ltransformatorenisolationsmoduls.
  • the mechanical stability is advantageously increased by the now approximately straight strut shape of the trapezoidal sides between the first and third layer.
  • an oil transformer isolation module according to the invention, at least one further planar layer and an associated further corrugated layer are arranged between the first and second layer, resulting in an alternating sequence of plane and corrugated layers.
  • This multilayer structure advantageously increases both the electrical insulation capability and the mechanical stability.
  • the number of alternating layers can also be twenty or higher, so that a vertical support element with excellent insulating properties can be formed with a very small square base area of an oil transformer insulation module of, for example, 10 cm edge length and correspondingly many layers.
  • an oil transformer insulation module has three or at most five layers and a footprint of one square meter or higher to be usable in its proper function as a barrier wall.
  • the first insulating material corresponds to the second insulating material, apart from the waveform. This simplifies the manufacture of an oil transformer isolation module. Differences in the insulating material could be based, for example, in its thickness, for example 1 mm to 4 mm, or in its flexibility, wherein pressboard variants are each a preferred embodiment.
  • the height of the cavities formed by the corrugated shape corresponds to at least twice the thickness of the non-corrugated second insulation material, wherein a four- or six-fold thickness may well be suitable.
  • the insulation module forms a barrier system which, due to its dimensional stability, also bears directly on the component to be insulated, even after thermal and vacuum-technical processes.
  • the cavities or the channels formed by the cavities extend parallel to an alignment axis, wherein the insulation module is bent at least in regions about a bending axis parallel thereto.
  • the layer structure of an oil transformer isolation module makes it possible in a simple manner to realize curved Konturabiteste. Its high mechanical strength reaches a ⁇ ltransformatorenisolationsmodul only in the layer composite, so that first the individual layers are to be brought into the desired shape before, for example, under application of a pressing pressure, a composite is formed. In this case, a bending of the corrugated third layer parallel to the alignment axis is the mechanically most sensible variant.
  • a suitable bonding agent is a high voltage resistant adhesive such as casein.
  • At least one lateral edge of a corrugated layer is offset inwards relative to the adjacent layers, so that a groove is formed.
  • this groove can be advantageously used to connect to the groove of another oil transformer insulation module, thus providing a modular building block system of standard modules.
  • two oil transformer insulation modules each having at least one groove are arranged side by side on the groove side, wherein a common slot cavity is formed by adjoining grooves.
  • the two oil transformer insulation modules are connected to each other by a further in the form adapted to the common Nuthohlraum and arranged in this further ⁇ ltransformatorenisolationsmodul. If a solid insulating element were used as the connecting element, this would lead to an insulation weak point of the connected modules at their connection point, because in this case the isolation-technical advantage of the oil-filled cavities would not be realized.
  • the use of an oil transformer insulation module for connecting two further oil transformer insulation modules ensures that a sufficiently high level of insulation is also provided at the connection point.
  • a modular system can be advantageously composed of basic geometric modules various arrangements, for example, at least partially curved ⁇ ltransformatorenisolationsmodule to an annular structure, which then axially enclose, for example, isolation technology critical components of an oil transformer, for example, within a dome of an oil boiler.
  • annular structure which then axially enclose, for example, isolation technology critical components of an oil transformer, for example, within a dome of an oil boiler.
  • isolation technology critical components of an oil transformer for example, within a dome of an oil boiler.
  • both a more rectangular or even a more circular structure is conceivable, which can simply be arranged like a segment around a component, which would not be possible with a non-modular ring structure.
  • Such ring structures are in Particularly simple way also from four completely equal segments feasible, which simplifies the production. But it is also any other combination conceivable, for example, staircase-like or U-shaped. Of course, sharp edges are to be avoided and executed with a corresponding bending radius, for
  • An oil transformer with an oil boiler and at least one oil transformer insulation module according to the invention or an arrangement of oil transformer insulation modules can thus also be manufactured in a particularly advantageous manner with a somewhat smaller oil tank.
  • Fig. 1 shows a section 10 through a portion of an oil-filled oil transformer Isolationsmoduls.
  • a first planar layer 12 of a first insulating material is connected at a plurality of connection points, one of which is designated by the reference numeral 22, with a third corrugated layer 16 of a second insulating material.
  • the other side of the third corrugated layer 16 is connected to a second planar layer 14 of a first insulating material at further connection points 24, so that between the flat layers 12, 14 and the corrugated layer 16th Hollows 18, 20 are formed, which are indicated in the figure as filled with oil 26.
  • These are open at the lateral edges of the oil transformer insulation module and have a channel-like shape.
  • An oil transformer insulation module only has its full electrical insulation capability if all the cavities are completely filled with a corresponding liquid insulation medium and no air-filled areas are left.
  • Material materials of pressboard or other stable pulp material are particularly suitable as insulating materials, wherein the thickness of a respective first or second layer may be for example 2mm to 5mm and the thickness of a corrugated third layer, for example 10mm to 20mm, the latter being an actual material thickness 30 and a height 28 of a respective cavity 18, 20 composed.
  • this structure is particularly lightweight, so that such a module compared to a solid insulation barrier wall, for example, when mounting in an oil tank of an oil transformer to be manufactured is particularly easy to handle.
  • the connection points 22, 24 can be realized for example with a suitable high-voltage resistant adhesive such as casein.
  • Fig. 2 shows a section 40a through two oil transformer Isolationsmodule 42, 44, which in turn have at one of its side edges a groove through which a respective Nuthohlraum 46, 48 is formed.
  • Manufacturing technology is the respective groove realized by a displacement or shortening of the corrugated layer to the inside, so that the two outer layers protrude accordingly.
  • the two oil transformer insulation modules 42, 44 are arranged on the groove side by side, so that a common Nuthohlraum is formed by the two Nuthohlsammlung 46, 48, as shown in the section 40a.
  • the section 40b corresponds to the section 40a, but here, instead of the Nuthohl gleich in their position, a third ⁇ ltransformatorenisolationsmodul is shown, which is positively arranged in the common Nuthohlraum and connects the other two ⁇ ltransformatorenisolationsmodule together.
  • the third oil transformer insulation module 50 also has a layer structure according to the invention with channel-like cavities, whereby it has an improved insulation capability compared to a correspondingly solid module. Therefore, it is advantageously avoided that the associated ⁇ ltransformatorenisolationsmodule have a reduced insulation capacity at the junction.
  • the depth of a groove should be two to six times the thickness of the corrugated layer to ensure a mechanically stable connection.
  • Fig. 3 shows a section 60 through two further connected oil transformer Isolationsmodule 62, 64, which are arranged in oil 70. These have a respective half-shell-shaped structure and in the assembled state form a hollow cylindrical element which extends around a rotation axis 72. Both oil transformer insulation modules 62, 64 have at their respective two straight edges a groove and are arranged against each other so that the respective opposing grooves each form a common Nuthohlraum. In these Nuthohlthough a slightly thinner sixth 66 and a seventh 67 ⁇ ltransformatorenisolationsmodul are arranged, through which the two other oil transformer isolation modules 62, 64 are positively connected. It should be expressly mentioned that the layer structure according to the invention with floodable cavities is not shown in this figure, but it is assumed to be present and flooded with oil 70.
  • the two oil transformer insulation modules 62, 64 are preferably made in a corresponding semi-cylindrical shape, wherein first each individual layer brought into the desired shape, provided in sections with an adhesive and was connected to the or each adjacent layers. A curing of the adhesive is preferably carried out under elevated pressure at an elevated temperature, for example in an oven. As usual with layered composites, they have after formation of the composite an extreme strength and low weight.
  • Fig. 4 shows a section through four similar oil transformer insulation modules, which are connected by four further oil transformer isolation modules to form a rectangular ring structure, in which case the corners each have a bending radius.
