Definitions
- the invention relates to a device for electrical shielding of a bushing output of a high voltage ⁇ line in the outer wall of an electrical Hochnapssge ⁇ rätes, wherein the shield is an electrically conductive screen interior and an exterior, the screen interior comprises at ⁇ closing insulation layer.
- the edge transitions and corners between the passage of the high-voltage line and the boiler wall perpendicular thereto are shielded according to the prior art such that a so-called shielding wire is arranged around the feed-through output within the high-voltage electrical device.
- This shielding wire is conventionally provided with an electrically conductive Ableungsinneren on the surface is electrically isolated, in particular by a paper insulation.
- differently shaped shielding rings are also known in the prior art which have a rectangular electrically conductive shielding interior.
- US 4,296,274 describes a high voltage feedthrough having a weatherproof shield.
- WO 00/19453 describes a high-voltage ⁇ guide with a high voltage conductor in a onstuben with Isolati- provided insulator at one end a
- a shielding electrode is arranged around the insulator, which extends from the flange in the axial direction over part of the length of the I-solators, wherein the number of insulation screens per unit length in the individual sections is different ⁇ Lich.
- a disadvantage of all known in the art shielding solutions for high-voltage bushings is that the previous solutions either structurally complex or not ensure complete shielding of the almost rectangular bushing output.
- the electrical shielding of the nearly rectangular corners and edges of the feedthrough output relative to the boiler wall is not completely guaranteed by the solutions provided in the prior art.
- Object of the present invention is therefore to provide an electrical screen, which guarantees a complete From ⁇ shielding of the corners and edges of an execution output in a high voltage electric device.
- This object is achieved by the features according to the invention Merkma ⁇ le of claim 1.
- the object is achieved in that the shield is designed as arcuate circle ⁇ segment to the nearly rectangular design of the implementation. This ensures that the field ⁇ course of the electric field in the vicinity of the almost right ⁇ angled implementation output is changed.
- Legally conventionally ⁇ the field distribution of the electric field in the vicinity of corners and edges is highly complex and insufficiently provides ⁇ previously monge by an electrical shielding.
- the invention shown SSE configuration of the electrical shield as arcuate circular segment with two elongate legs influences the course of the electric field in the vicinity of the feedthrough output in such a way that the housing of the high-voltage electric device is electrically shielded completely in the region of the bushing output.
- the electrical shield is positioned around the nearly rectangular feed-through output so that the radius of the arcuate circular segment extends through the corner of the nearly rectangular feedthrough output.
- ⁇ by the shield is symmetrically positioned about the edges of the almost right-angled bushing output niert.
- the shape of the shield corresponds to an idealized field profile of the electric field in the vicinity of the feedthrough output.
- the radius of the arc ⁇ shaped circular segment of the shield is smaller than four times the length of the legs.
- the radius is preferably a length of 10 mm to 500 mm, preferably 100 mm.
- the shield is shielded by an additional barrier system.
- the barrier system is mechanically connected to the bar ⁇ rierensystem the implementation and / or the barrier system of the electrical high voltage device.
- the shield is formed around the lead-through output as a circumferential one-piece element. In this way, given a cost herstel ⁇ development of the shield, and a form-retaining effect of the shield.
- individual shield segments are arranged in a circle around the lead-through output. The same applies to a corresponding Barrie ⁇ rensystem, for additional shielding.
- the shield is connected to the electrical ground. It is also possible to use this electrical shield at the same time as a magnetic shield when making the shield of conductive material. Then local heating, caused by eddy currents, which can lead to considerable warming and possibly damage the electrical high-voltage device, avoided ⁇ the.
- the shield is at least partially made of conductive material, which is partially interrupted by non-conductive material.
- the shield consists of a carrier material which is at least partially encased with a conductive layer, in particular coated or encased.
- Fig. 1 is a schematic sectional view of the shield
- Fig. 2 is a schematic sectional view of the shield around a cable feedthrough with additional
- the figure Fig. 1 shows a schematic sectional view of the basic construction of the present shield 10.
- the dotted line represents the rotational axis of the Abschir ⁇ mung 10.
- In the surroundings tion of the shield 10 is an isolation medium, in particular an oil, within the electrical high voltage device available.
- the nearly perpendicular to a feed-through output (not shown) arranged shield 10 has two legs 23 which are part of the arcuate Kreissegmen ⁇ tes. The leg length is defined with respect to the transition of the arcuate circular segment to the respective straight legs 23.
- the radius 22 defines the shape of the bogenför ⁇ shaped circular segment of the shield 10 and passes through the not shown corner of the line feedthrough output 21 (not shown).
- FIG. 2 shows a shield 10 with an additional barrier system 14 around a bushing output 21 for a high-voltage electrical line.
- the dashed line represents the axis of rotation of the shield 10, the circular passage 15 and the circular outlet 16.
- a Lelei ⁇ tion 16 is arranged with a paper insulation 17, the e-lektwitz connection of the high voltage device with a ⁇ ßeren high-voltage network, in particular an HVDC network allows.
- the shield 10 is arranged such that a symmetrical about the vertex of the almost rectangular bushing outlet 21 coverage of both angles of the passage 15 and the boiler wall 20 is ensured.
- the to ⁇ additional barrier system 14 around the shield 10 ensures in conjunction with the circulating oil within the high voltage electrical appliance and performing 15 an optically timale electrical shielding of the corners of the feedthrough ⁇ output 21.
- the barrier system 14 of the shield 10 with the barrier system 14 are connected within the implementation 15 and / or the high voltage electrical equipment, so that a continuous barrier sys- is given from the execution output 21 to the implementation 15.
