Definitions
- the invention relates to a barrier arrangement for a lungs fürbowung with juxtaposed barriers, which are arranged at predetermined distances from each other.
- Shielding electrode which is integrated into the barrier system, electrically shielded from each other.
- DE 10 2005 021 255 B4 describes a barrier system for a line feedthrough of an electrical system, in which the individual barriers in the form of plug-in elements are plugged into each other.
- This connection system is preferably located in a grounded dome, which is attached to the lid or on a side wall of the electrical system, in particular the transformer or throttle boiler.
- the shielding electrode has a paper insulation, which ensures a corresponding electrical shielding.
- the length of the barriers can be up to 3,000mm with a diameter of up to 1,500mm.
- the thickness of the barriers is between 3mm and 5mm.
- the object of the present invention is therefore to increase the electric strength between the Kirs Struc and the barrier arrangement.
- a barrier arrangement according to the features of claim 1. According to the invention, it is provided between the barrier arrangement and the line soubuchung at least one barrier element to form an additional radial Olumble is arranged.
- an additional radial radial oil path is understood as a radial circulation system formed by at least one almost rotationally symmetrical barrier element, wherein within the additional radial oil path the oil can circulate in the radial and axial direction as cooling and insulating medium.
- barriers are integral segments which can also be connected to one another and, if appropriate, also pushed into one another and thus form a barrier system, as disclosed, for example, in DE 10 2005 021 255 B4.
- barrier elements form additional radial oil paths.
- the barrier arrangement is provided that the additional Olumblen have a comparison with the Olumblen the barriers reduced distance.
- the barrier element comprises pressboard.
- a plurality of barrier elements are arranged at virtually constant distances from the line leadthrough and / or relative to one another.
- the distances of the additional radial oil paths may vary, in particular a smaller distance in the lower region of the barrier elements is advantageous in comparison to the distance in the upper region, since in this way the permissible field strengths can be increased in the lower region.
- the Kirs handbuchung is formed as a funnel or cone, which can be additionally formed at the lower end by a cylindrical termination.
- the shape of the barrier elements can be adapted to the respective electrical or structural conditions as a whole or as regards individual barrier elements.
- an axial extension of the barrier elements beyond the upper part of the electrode is advantageous in the case of a DC voltage applied to the electrode.
- the barrier element can advantageously be fastened to the outer barrier arrangement or to the leadthrough and is radially spaced apart from the electrode with spacers.
- the Krafts slideatung serves in particular as a discharge to a transformer and / or to a choke coil.
- the barrier arrangement is advantageously configured as a test barrier arrangement. These test barrier arrangements differ from the arrangement used in a transformer or in a choke coil only in the lower region of the electrode arrangement and can be used for the high-voltage tests of line feedthroughs. Further advantageous embodiments emerge from the subclaims. The object of the invention will be explained by means of the following figures. It shows
- Fig. 1 shows a partial section of a discharge as
- Fig. 2 shows a partial section of a discharge as
- Fig. 3 shows a partial section of a discharge as
- Fig. 1 shows a section of a discharge 1, wherein the representation of Fig. 1 is a sectional drawing through a rotationally symmetrical design discharge 1 and posted the axial axis of rotation 6 only the right part as a portion of the discharge line 1 in FIG. Relative to Kirs notebooksmithung 3 of the transformer (not shown), the barrier assembly 2 is arranged.
- the rotation-symmetrical barrier arrangement 2 comprises three barriers 7 a, 7 b, 7 c, which are arranged relative to the line lead-through 3.
- a paper-insulated electrode 5 is part of the electrical shielding of the discharge line 1. Between the barrier arrangement 2 In the example shown in FIG.
- the line bushing 3 has a barrier element 4a integrated therein, which forms an additional radial oil path 8a within the outlet 1 which is smaller than the conventional oil path, so that the permissible field strengths within the circulating oil can be increased.
- the additional radial oil path 8a is formed by the barrier element 4a and the leadthrough 3.
- FIG. 2 A partial section of an outlet 1 (not shown) as a sectional drawing with two rotationally symmetrical barrier elements 4a, 4b for the formation of two additional radial Olrown 8a, 8b between the Kirs pressbowung 3 and the electrode 5 is shown in FIG.
- the illustration of FIG. 2 is a sectional view through a rotationally symmetrical outlet 1 with respect to the axial axis of rotation 6 and shows only a portion of the discharge line 1.
- the first additional radial oil path 8a is formed by the arrangement of the first barrier element 4a relative to Kaus pressbuckung 3
- the second additional radial oil path 8b is formed by the almost constant distance A between the first and the second barrier element 4a, 4b.
- This barrier arrangement 2 allows the operation of higher electric field strengths by the formation of the additional radial Olrown 8a, 8b. Im shown
- the barrier elements 4a, 4b have a straight shape and do not project beyond the electrode 5.
- FIG. 3 shows a partial section of an outlet 1 (not shown) as a sectional drawing with three rotationally symmetrical barrier elements 4a, 4b, 4c for forming additional radial oil paths 8a, 8b, 8c between the cable feedthrough 3 and the electrode 5.
- the additional radial oil paths 8a, 8b, 8c are due to the different shapes of the barrier elements 4a, 4b, 4c and their relative arrangement to each other different shapes and diameters.
- the third additional radial oil path 8c in the lower part has a smaller diameter than in the upper part of the barrier elements 4a, 4b, 4c.
- the barrier elements 4 a, 4 b, 4 c have an angled shape, which is designed parallel to the shape of the conduit 3 in the upper area.
