Definitions

  • the invention is based on a high-voltage bushing with at least one conical part, which consists of a wound insulating material web.
  • Such a high-voltage bushing gives rise to improvements in terms of its mechanical strength, which is usually not very large.
  • the invention is therefore based on the object of proposing a high-voltage bushing which is distinguished by a high mechanical strength, the high mechanical strength should be achievable with comparatively little production effort.
  • a major advantage of the high-voltage bushing according to the invention is that by applying the rings or short hoses made of shrink material to their conical part, they obtain a relatively high mechanical strength, which advantageously also leads to an increase in the electrical strength.
  • the high mechanical strength is only achieved in a production-technically advantageous manner by applying rings or hoses made of shrink material, which shrink due to local heat treatment and thereby exert a relatively high mechanical strength on the windings from the insulating material web.
  • the high-voltage bushing according to the invention is particularly advantageous if it is provided with embedded conductive inserts; If in this case the rings or hoses are advantageously located at the locations of the conductive inserts on these or on the cone-shaped part, then the shrink pressure of the rings or hoses on the winding from the insulating material web, which is generated as a result of the heat treatment, becomes precisely at the locations a high pressure is exerted on the inserted inserts, which fixes the inserts in the predetermined position, so that the inserts cannot move within the high-voltage bushing even during transport, and thus perfect capacitive control is maintained.
  • the high-voltage bushing - as known per se has step-shaped shoulders on its conical part and if the rings or hoses are applied to the step-like steps.
  • the rings or hoses shrink as a result of the heat treatment, the shrink pressure is then fully transferred to the winding from the insulating material web, and the rings or hoses cannot slide sideways on the conical part of the high-voltage bushing and the windings cannot be displaced from the insulating material web.
  • the figure shows in section a conical part of an embodiment of the high-voltage bushing according to the invention.
  • the high-voltage bushing 1 contains a tube 2, which is expediently a metal tube.
  • the insulating material web 3 which is preferably a plastic film, is wound onto this metal tube.
  • the width of the insulating material sheet 3 decreases correspondingly with the high-voltage bushing 1 growing radially. Appropriate dimensioning of the insulating material web 3 ensures that the conical part 4 has step-shaped shoulders 5, 6 and 8.
  • conductive inserts 9, 10, 11 and 12 are also wrapped in order to achieve a capacitive control.
  • the inserts 9 to 12 can consist of metal foils.
  • Hoses 13, 14, 15 and 16 made of shrink material are applied to the step-shaped heels 5 to 8.
  • the hoses 13 to 16 are subjected to a heat treatment after their application and thereby shrink. In doing so, they exert a pressure in the radial direction, as a result of which the high-voltage bushing 1 or its conical part 4 is strongly compressed precisely at the locations of the wrapped metal foils (inserts 9 to 12); Due to the high surface pressure, the inserts 9 to 12 are held firmly in their position. At the same time, the mechanical strength of the entire high-voltage bushing 1 is increased and, in addition, protection is provided for the edges 17 of the inserts 9 to 12.
  • the rings or hoses made of shrink material can rest directly on the conductive inserts and can be completely or partially covered by the insulating material.
  • the invention proposes a high-voltage bushing which is distinguished by a relatively high strength and which, in the case of embedded conductive inserts, ensures that these inserts are fixed in their predetermined position.
