Definitions

  • the invention is in the field of basic electrical components and is to be used in the structural design of an insulator which is combined with a surge arrester to form an assembly.
  • the insulator consists of a hollow housing with a shield and has a metal base and a metal head.
  • the resistance elements of the arrester arranged within the housing here form individual sections of the wall of a hollow cylinder or a blunt cone. This cylinder or cone is placed on one end on contact parts which are guided radially outwards through the wall of the insulator; at its other end the cylinder or cone is connected to the high-voltage conductor (JP 59- 207513A, JP 59-207514A).
  • the invention is based on the object of giving the assembly a simple structure and thereby a more compact design.
  • the insulator as a composite body with a solid body and a covering cast or sprayed onto the body consists of an elastomer and that the surge arrester is embedded in the elastomer covering.
  • “isolator” is understood to mean both solid and hollow insulators and synthetic resin insulating bodies (bushings) arranged around a conductor, in particular those which are used for voltage levels from 6KV.
  • the surge arrester is not within the fixed body of the insulation. tors arranged, but it is assigned to the insulator outside the fixed body.
  • the intended "back-up" assignment means that the structure of the solid body and its dimensions do not have to be changed, while the embedding in the cast or injection-molded elastomer coating of the composite body can be implemented relatively easily. This applies in particular if standard elements in the form of solid cylindrical or cuboid bodies are used as resistance elements of the conductor, which may have a central bore for assembly purposes.
  • - Composite body with a solid body made of a glass-fiber reinforced plastic tube or rod and with A cast or sprayed-on elastomer sheathing is common for high-voltage insulators.
  • the elastomer coating is usually designed as a shield.
  • the surge arrester integrated in a composite body can consist of one or more, for example two or four, arrester columns made up of resistance elements.
  • two arrester columns it is advisable to arrange the columns closely adjacent to one another or diagonally to the axis of the bushing insulator; If there are three or more arrester columns, it is advisable to divide the columns into two groups and to arrange the two column groups opposite each other diagonally to the axis of the isolator.
  • the arrester columns are preferably arranged in mirror image to a plane that receives the axis of the insulator. In all of these cases, the additional consumption of elastomer material associated with the thickening of the insulator casing can be kept as low as possible.
  • the outer contour of the elastomer covering is matched to the outer contour of the solid body and the arrester column / s.
  • the mechanical mounting of the arrester columns provided by embedding the arrester columns in the cast or sprayed-on elastomer sheath can be improved in that the for the electrical connection of the arrester columns the foot part and the head part of the insulator provided connecting elements are designed as mechanical support members.
  • the connection elements can have the shape of elongated profile bodies or slender bolts.
  • the insulator in whose elastomer sheath the surge arrester is integrated, can be used differently with its fixed body.
  • the interior can accommodate an electrical component such as a bushing - with or without capacitor control -, a cable end provided with a field control or an end closure, or a voltage divider; but it can also be penetrated by a mechanical component such as a shift rod and perform a purely support function.
  • FIGS. 1 to 5 shows an assembly with an overvoltage arrester and integrated into a cast silicone shield of a hollow composite body
  • Figure 2 is a cross-sectional view of Figure 1.
  • Figures 3 to 5 show two variants of Figure 2 with respect to the arrangement of several arrester columns.
  • FIG. 1 shows an assembly which essentially consists of a tubular high-voltage insulator 1 and an overvoltage arrester 2 exists and is arranged on a circuit board 3.
  • High-voltage insulator 1 contains an electrical component 4 in its interior, which is a high-voltage bushing in the form of an electrical conductor provided with a capacitor control.
  • the high-voltage insulator 1 of the assembly has a housing 11, which consists of a glass fiber reinforced plastic tube 12 and a shield 13 made of an elastomer applied to this tube.
  • the shielding 13 is dimensioned such that the high-voltage insulator 1 is designed for a voltage level of 145 kV.
  • the housing 11 is further provided with a metal base 14 and a metal head 15.
  • the surge arrester 2 consists of a column 21 comprising a plurality of resistance elements 22 and is electrically connected to the metal base part 14 via a lower electrical connection 23 and to the metal head part 15 via an upper electrical connection element 24.
  • the connection elements 23 and 24, which are only shown schematically, are mechanically so stable that the arrester column 21 is securely supported. Otherwise, the arrester column 21 is completely embedded in the encapsulation of the elastomer shield 13.
  • the conductor column 21 is embedded in such a way that, with an oval contour of the shields 17, the actual wall 18 of the elastomer shield 13 has a contour 16 which is adapted to the outer contour of the glass-fiber reinforced plastic tube 12 and the associated conductor column 21 and which thus has a substantially uniform wall thickness over the circumference of the glass fiber reinforced plastic tube.
  • two arrester columns 21 are arranged mirror-symmetrically to a plane E1, which receives the axis A of the high-voltage insulator 1.
  • Umbrellas 17 but also provide the wall 18 with an outer oval contour.
  • the contour 19 of the wall of the elastomer shield is matched to the outer contour of the glass fiber reinforced plastic tube 12 and the two arrester columns 21.
  • a total of four arrester columns 21 are arranged, which are combined to form two assemblies in such a way that the two assemblies are located diagonally to the axis A of the high-voltage insulator and are arranged mirror-symmetrically to both a plane E1 and a plane E2 which accommodate axis A of the high voltage insulator.
  • arrester columns are expediently arranged in such a way that an arrester column according to FIG. 2 is assigned a further arrester column on both sides. In this case too, there is a mirror-symmetrical arrangement with respect to the plane El.

Abstract

L'invention concerne un nouveau module comprenant un isolant (1), relié à un limiteur de surtension (2) constitué d'éléments de résistance. En tant que corps composite, ledit isolant (1) présente un corps rigide (12), par exemple un tube plastique renforcé de fibres de verre, et une gaine élastomère (13) coulée sur ce dernier, par exemple un blindage. Selon ladite invention, le limiteur de surtension (2) est noyé dans le scellement de la gaine élastomère (13).
