Definitions

  • the invention relates to an insulating element according to the preamble of claim 1.
  • Insulating elements of the type required in the preamble of claim 1 are used, for example, to isolate transformer or choke coil ends of high voltage.
  • 1 shows a partial section through an oil-filled transformer, the undervoltage winding is designated by 1 and the high-voltage winding is designated by 2.
  • insulating elements 3 to 9 are arranged in the oil-filled space between the windings 1 and 2.
  • the similarly designed insulating elements 4 to 7 each consist of an insulating cylinder 10 and an angle ring 11 attached thereto.
  • Such an angle ring 11 is illustrated in detail in FIG. It consists of a cylindrical part 11a and an outwardly facing flange 11b.
  • Figure 1 shows a section through the right part of the angle ring 11 (in reverse ter position, ie with the cylindrical part 11a) pointing downwards.
  • the insulating elements 5, 6 and 7 are constructed in the same way as the insulating element 4; the only difference is the dimensioning of the angle rings 11, in particular the radius of curvature between the cylindrical part 11a and the flange 11b.
  • the insulating element 3 consists of an insulating cylinder 10 and an insulating ring designed as a cap ring 12, which is illustrated schematically in FIG.
  • the cap ring 12 includes a cylindrical portion 12a and an inward flange 12b.
  • the insulating cylinders 10 of the insulating elements 3 to 7 are sharpened at their end facing the angle rings 11 or the cap ring 12 by reducing their wall thickness.
  • the cylindrical parts 11a of the angle rings 11 and 12a of the cap ring 12 are sharpened in the overlap region by reducing the wall thickness.
  • a disadvantage of this known embodiment is that the sharp edge of the two sharpening points (on the insulating cylinder 10 and on the angle ring 11 or cap ring 12) is at high risk of tearing is. This results in difficulties especially during transport and assembly. The manufacture of the sharpened parts is also relatively expensive.
  • the invention is therefore based on the object, while avoiding the disadvantages described, to form an insulating element of the type required in the preamble of claim 1 in such a way that, with the same electrical strength, there is a higher mechanical strength and the manufacture, transport and assembly are simplified.
  • FIG. 1 An embodiment of the invention is illustrated in Fig.4.
  • the same reference numerals as in FIG. 1 are used for the same parts.
  • the insulating cylinders 10 of the insulating elements 3 to 7 are designed in the same way as in the known embodiment according to FIG. sharpened in the overlap area by reducing their wall thickness.
  • the angle rings 11 'and the cap ring 12' are designed differently from the known embodiment according to FIG. They are conical in the overlap area 11'a or 12'a, but with a constant wall thickness, the cone angle corresponding to the sharpening angle of the insulating cylinder 10. This results in a thickening of material 13 at the end of the angle ring 11 'or the cap ring 12' facing the insulating cylinder 10, which, however, lies in an approximately homogeneous part of the field (to illustrate the field formation, two equipotential surfaces 14, 15 are shown in FIG. 4 Field shown schematically).
  • the overlap area 11'a or 12'a is dimensioned accordingly.
  • the angle rings 11 'and cap rings 12' do not need to be provided with the sharpenings previously required. This results in a much better mechanical strength with the same electrical strength. At the same time, this simplifies transportation and assembly.
  • the angle rings 11 'and cap rings 12' can be attached in the most favorable position in terms of field, the oil channel between the windings 1 and 2 which is necessary for cooling being maintained. Material thickenings 13 are only present in the relatively uncritical area of the homogeneous field.
