Definitions

  • the invention relates to a surge arrester according to patent application P 30 12 741.4, which has a column arranged in a housing and formed from a multiplicity of arrester elements and a plurality of shielding bodies enclosing the column, which are connected to one another by supporting bodies, and a device for fastening Has arrester elements.
  • the shielding bodies are the load-bearing parts of the arrester elements and also have an influence on the stress distribution over the length of the entire column of arrester elements.
  • nearby adjacent earthed components e.g. B. a grounded metal enclosure as the housing of the column of arrester elements, however, an uneven voltage distribution can still be caused, which interferes with the function of the surge arrester.
  • the invention is also based on the object, the chip using voltage-controlling elements To improve voltage distribution over the length of the surge arrester.
  • the invention provides that in a surge arrester of the type mentioned, voltage-controlling elements are arranged between adjacent shielding bodies.
  • this measure appears to agree with the known arrangement of capacitors between adjacent shielding rings, but is by no means obvious and can therefore not be taken for granted. Rather, there was the view that the arrangement with load-bearing shielding bodies according to the main patent had such a good shielding and capacitive influence on the arrester elements that all further voltage control measures were unnecessary.
  • An essential property of the invention is that the voltage-controlling elements come in a mechanically parallel arrangement to the insulating support bodies present between the shielding bodies. Their support effect is strengthened by the voltage-controlling elements, which enables more favorable dimensioning. In this context, it is advantageous to design the voltage-controlling elements in accordance with the size and type of fastening in accordance with the insulating support bodies.
  • a voltage control that acts locally to different degrees. This can be achieved in the context of the invention in that, with the same electrical dimensioning of the voltage-controlling elements, a different number of elements is arranged from shielding body to shielding body in order to compensate for the influence of earth capacity in the sense of a uniform voltage distribution over the length of the surge arrester.
  • 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 somewhat 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, for example 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.
  • the shielding body 5 On the circumference of the shielding body 5 there are three insulating support bodies 12 and also three voltage-controlling elements 13, for example capacitors. The same distances are present between these components 12 and 13. If necessary, a larger or smaller number of voltage-controlling elements 13 must also be accommodated. 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.
