Definitions

  • the invention relates to a high-voltage insulator with arc protection ring.
  • Above-ground high-voltage power lines are routed regularly over high voltage pylons.
  • high voltage insulators are provided at the suspension points between the high voltage lines and the high voltage pylons, respectively. Long rod insulators are often used, which are suspended on trusses of the high voltage mast and at the free end of the high voltage line is attached.
  • arc protective rings are known.
  • the arc protection rings are arranged at both ends of the actual insulator and surround the insulator substantially annular. Since the arc protection rings are made of metal and thus electrically conductive, the arc either forms directly between the arc protection rings or the base of the arc migrate shortly after the formation of the arc to the arc protection rings. As a result, a direct contact or an immediate proximity between the arc and the actual insulator is only briefly existing or completely avoided. As a result, damage to the insulator can be reduced.
  • the invention is therefore based on the object to provide a high-voltage insulator with arc protection ring, in which the disadvantages known from the prior art no longer occur or only to a lesser extent.
  • the invention relates to a high-voltage insulator comprising a long-rod insulator with a shank and circular shields arranged thereon, an insulator cap at the upper end of the long-rod insulator for fastening the high-voltage insulator to a high-voltage mast and an arc protection ring surrounding the insulator cap or the part of the long-rod insulator closest to the insulator cap, wherein at least the uppermost, the insulator cap nearest shield of the long-rod insulator is designed as a shield for the other screens, wherein the maximum diameter of the other screens at least 30 mm smaller than the inner diameter of the arc protection ring, the diameter of the at least one protective shield is at least 10 mm smaller than the inner diameter of the arc protection ring and the diameter of the at least one protective shield is at least 20 mm larger than the maximum diameter of the other screens.
  • the functionality of the insulator or the arc protection ring should not be limited.
  • other umbrellas while umbrellas of a long-rod insulator are referred to, which are not designed as protective screens or a protective screen accordingly.
  • the at least one shield designed as a shield of the long-rod insulator should thereby have a radius of at least 20 mm larger than the other screens, being parked especially at alternating diameters of the other umbrellas on the largest diameter of the other umbrellas. It has been shown that a sufficient protection against contamination of the other lying screens with bird droppings can already be achieved by a correspondingly larger diameter of the protective screen.
  • the bird droppings landed on a protective screen can be washed off in the rain, which occurs due to the larger diameter especially on the shields designed as umbrellas, so that a self-cleaning effect occurs.
  • due to the at least 20 mm larger diameter of the umbrellas ensures that the detached from those designed as umbrellas screens shielded bird droppings does not land on the underlying other umbrellas.
  • the diameter of the at least one shield formed as a shield is at least 10 mm smaller than the inner diameter of the arc protection ring, it is ensured that neither the arc protection impaired nor the shields designed as umbrellas are damaged when an arc occurs.
  • a distance of 10 mm between the shield and guard ring may be sufficient because due to the resulting from the immediate vicinity between the shield and guard ring in the axial direction of the long-rod insulator geometry when an arc occurs a foot point on the arc protection ring this screen is sufficiently spaced from the arc and no damage can be expected.
  • the other screens are also due to the at least 30 mm from the inner diameter of the arc protection ring of smaller diameter also sufficiently protected from damage by an arc.
  • the diameter of the at least one protective screen is at least 17.5 mm and / or at most 42.5 mm smaller than the inner diameter of the arc protection ring.
  • the diameter of the at least one protective screen is at most 40 mm larger than the maximum diameter of the other screens.
  • a maximum of 40 mm larger diameter of the shields is sufficient to protect the other screens from the deposition of bird droppings and to prevent in the event of rain a conductive wetting of the other screens with a mixture of water and bird droppings.
  • the diameter difference can be achieved in the rule that the fittings for fixing the high voltage insulator and the arc protection ring with respect to an insulator according to the prior art with comparable insulation properties can remain unchanged.
  • the lowermost shield farthest from the insulator cap is formed according to a protective shield. Even if this lowermost shield can not exert any protective effect against bird droppings in relation to the other shields, an embodiment corresponding to a protective shield - that is to say, in particular with a comparable diameter - is advantageous for transport and storage of the high-voltage insulator or its long-rod insulator.
  • At least one screen not located at one end of the long-rod insulator is designed as a protective screen.
  • an internal shield of the long-rod insulator is designed as a protective screen - that has a comparable or the same diameter with the other protective umbrellas - the risk of breaking through the long-rod insulator during transport and storage in a horizontal position can be further reduced.
  • an internal protective screen can also protect the underlying screens against soiling from above, which has not already been prevented by the uppermost protective screen.
  • At least two adjacent other screens of the long bar insulator may have different excursions.
  • the alternation of umbrella diameters is then no longer limited to pairings of protective screens and other screens, but expressly includes at least two adjacent other screens.
  • the creepage distance can be extended over the insulator.
  • the long-rod insulator may comprise at least ten, preferably at least fifteen screens and / or be made of ceramic or glass-fiber reinforced plastic.
  • the long-rod insulator may be designed in accordance with the standards DIN EN 61466/2 (composite long-rod insulator) or DIN 48006/2 (long-rod insulator), the screens designed as protective shields representing modifications of these standards.
  • the individual screens of the long-rod insulator can have peripheral drip edges on their outer edge.
  • the high voltage insulator may also have an arc protection ring at its lower end.
  • FIG. 1 a first embodiment of a high-voltage insulator 1 according to the invention is shown.
  • the high-voltage insulator 1 comprises a long-rod insulator 10, which is connected at its upper end to an insulator cap 2. About this designed as a fork cap insulator cap 2, the high-voltage insulator 1 can, for example, attached to a traverse of a high voltage mast. At the lower end of the long-rod insulator 10 also designed as a fork cap insulator cap 2 'is provided. At this lower insulator cap 2 ', the high voltage line can be attached. To each of the insulator caps 2, 2 ', an arc protection ring 3, 3' is arranged, which surrounds the respective ends of the long-rod insulator 10.
  • the arc-protective rings 3, 3 ' are formed as metal rings, which can form in the case of an arc over the high-voltage insulator bases over which the arc current is dissipated into the earth.
  • the two arc protection rings 3, 3 'Hornableiter have to be self-extinguishing.
  • the long bar insulator 10 is made of ceramic and comprises a shaft 11 and arranged thereon circular shields 12. In the illustrated embodiment, twenty umbrellas 12 are provided.
  • the long-rod insulator 10 and thus also the screens 12 are designed essentially in accordance with the standard DIN 48006/2, wherein all the screens 12 have peripheral drip edges 13 on their outer edge.
  • the insulator caps 2, 2 'and the arc protection rings 3, 3' can also be standardized components.
  • the topmost, so the upper insulator cap 2 closest shield 12 of the long-rod insulator 10 is configured as a protective screen 12 '.
  • the other, not designed as umbrellas screens 12 “have a maximum diameter which is smaller by approximately 37.5 mm than the inner diameter of the arc protection rings 3, 3 ', the diameter of the protective screen 12' only by about 17.5 mm smaller than the inner diameter of the upper arc protection ring 3.
  • the diameter of the protective shield 12 ' is thus larger by approximately 20 mm than the maximum diameter of the other shields 12 ".
  • FIG. 2 a second embodiment of a high-voltage insulator 1 according to the invention is shown.
  • the high-voltage insulator 1 compensates for this in many parts FIG. 1 , which is why reference is made to the above statements. Only the long-rod insulator 10 is, as explained below, of the embodiment according to FIG. 1 deviating executed.
  • the long bar insulator 10 is again made of ceramic and comprises a shaft 11 and arranged thereon circular shields 12, but in principle each adjacent umbrellas 12 have different projections or diameter.
  • the screens 12 are each carried out analogously to the standard DIN 48006/2 and have - albeit in FIG. 2 not explicitly shown - in each case a drip edge 13 (see. FIG. 1 ) on.
  • the top, the upper insulator cap 2 closest shield 12 of the long bar insulator 10 and a centrally located and thus not at the end of the long bar insulator 10 screen 12 are each as a protective screen 12 ', the lowest, the lower insulator cap 2' closest screen according to a protective shield 12 'configured ,
  • the umbrellas in question 12 ' have a diameter which is smaller by approximately 17.5 mm than the inner diameter of the two arc-protection rings 3, 3'.
  • the diameter of these screens 12 is about 20 mm larger than the maximum diameter of those screens 12 "which are not designed as a protective screen 12 'or according to a protective screen 12'
  • a relation to the inner diameter of the arc protection rings results 3, 3 'by about 37.5 mm smaller diameter, while the smaller of the other screens in the illustrated Embodiment are smaller by about 47.5 mm than said inner diameter.
  • the protective screens 12 'at the upper end and in the middle of the long-rod insulator 10 provide protection against contamination, in particular by bird droppings, relative to the respective underlying umbrellas 12 "
  • the lowermost shield 12 of the long-rod insulator 10 designed according to a protective shield 12' facilitates together with the other protective shields 12 'essentially the transport and storage of the long-rod insulator 10 in a horizontal position, in particular before the insulator caps 2, 2' are attached to the long-rod insulator 10.
