Definitions

  • the invention relates to a surge arrester with a column arranged in a grounded housing and formed from a multiplicity of conductor elements, a plurality of shielding bodies surrounding the column and voltage-controlling elements arranged between adjacent shielding bodies.
  • Such a surge arrester is known from DE-A-29 38 073.
  • the disk-shaped arrester elements are stacked one above the other in the form of a column, the lowermost being connected to earth and the uppermost disk being connected to high voltage.
  • This column is surrounded by ring-shaped, electrically conductive shielding bodies, between which ohmic resistors are arranged as voltage-controlling elements, which form a chain lying parallel to the series connection of the arrester elements.
  • This is intended to achieve an equalization of the voltage distribution of the known surge arrester arranged in a metal, earthed housing, the housing being filled with an insulating agent, such as sulfur hexafluoride.
  • the invention has for its object to improve the voltage distribution over the length of the surge arrester using voltage-controlling elements.
  • the invention provides that in a surge arrester of the type mentioned, the shielding bodies are connected to one another by supporting bodies and have a device for fastening arrester elements, and that the voltage-controlling elements are attached between shielding bodies connected by insulating supporting bodies and are of the same size and type the attachment as the insulating support body.
  • the voltage-controlling elements thus arrive in a mechanically parallel arrangement with the insulating support bodies present between the same shielding bodies. Their support effect is strengthened by the voltage-controlling elements, which enables favorable dimensioning.
  • FIG. 1 has a grounded metal housing 2, which is provided with a bushing 3 for connection to a conductor 4 carrying high voltage.
  • a column of arrester elements formed from shielding bodies 5, 6 and 7.
  • the middle six shielding bodies 5 have a slightly smaller diameter than the upper shielding body 6 and the lower shielding body 7.
  • Each of these shielding bodies 5, 6 and 7 encloses a number of arrester elements, e.g. B. of voltage-dependent resistors based on zinc oxide or a combination of voltage-dependent resistors and spark gaps.
  • 2 shows as an example that four arrester elements 11 are arranged in a star shape between the central connecting body 10 and one of the shielding bodies 5.
  • These can be zinc oxide resistors, which are housed in their own housing.
  • voltage control elements 13 e.g. B. capacitors that have the same size and type of attachment as the insulating support body. The same distances are present between these components 12 and 13. If necessary, a larger or smaller number of voltage-controlling elements 13 is also included. bring. For this purpose, only the pitch angle needs to be changed accordingly in order to, for. B. between two successive insulating support bodies 12 instead of a voltage-controlling element 13 to accommodate two of them.
  • FIG. 3 Another possibility for varying the number of voltage-controlling elements is shown in FIG. 3.
  • a voltage-controlling element 14 is used, which has essentially the same mechanical properties as the insulating support body 12, i. H. just as it has a supporting function. Due to this property, the voltage-controlling element 14 can replace the insulating support body in whole or in part. Maintaining a symmetrical arrangement of the insulating support bodies as in FIG. 2 is therefore unnecessary. Accordingly, it is shown in FIG. 3 that three insulating support bodies 12 and a voltage-controlling element 14 are arranged in the corner points of a square.
