Definitions

  • the invention relates to a mechanically stressed plastic insulating part according to the preamble of claim 1.
  • Such insulating parts such as shift rods, must be able to transmit high, often jerky, forces over longer periods of time without breaking or damage occurring.
  • the known glass fiber reinforced plastic insulating bodies also lose so much strength due to the decomposition products mentioned that they are no longer able to perform the reinforcement function intended for them.
  • the invention has for its object to provide mechanically stressed plastic insulating parts for high-voltage switchgear containing sulfur hexafluoride gas, in which electrical discharges and / or arcs occur at least temporarily, these insulating parts having a high mechanical strength against the decomposition products of SF6 should be sufficiently stable and should be economically advantageous.
  • Such glass fibers are commercially available inexpensively.
  • plastics known per se can be used, for example epoxy resins, polyester resins, silicone resins, polyurethane resins, phenolic resins and melamine resins.
  • Resin compositions are naturally preferred in the production of the insulating parts according to the invention, which have a pot life sufficient for mixing and the best possible shaping at a relatively low viscosity.
  • Known cycloaliphatic epoxy resins are advantageous in this regard when using suitable hardeners.
  • size-free glass fibers are contained in the insulating part according to the invention.
  • Such fibers can e.g. obtained from sized fibers by heat treatment.
  • the initial strength of the insulating parts can be lower than for those with the same but sized glass fibers. This could be due to fiber breakage and thus shorter fiber length.
  • a fragmentary, longitudinally sectioned section of an encapsulation tube 1 is shown, the cavity 2 of which is filled with SF 6 gas, and in which a tubular, hollow shift rod 3 is arranged lengthwise. Detects at the partially cut point of the shift rod 3 one that their wall 4 is a laminate of a glass fiber reinforcement 5 and a plastic 6.
  • two shift rods are provided with a glass fiber reinforcement made of commercially available glass free of boron and boron compounds and low in alkali according to FR-A-1 435073.
  • the fibers of the first shift rod are sized, those of the second shift rod are unsized.
  • a third shift rod is made as a comparison test with a glass fiber reinforcement made of commercially available E-glass, which contains boron and has a normal alkali content.
  • a plastic mixture was prepared for the casting, which contained 100 parts by weight of cycloaliphatic epoxy resin and 80 parts by weight of hexahydrophthalic anhydride.
  • Laminating was carried out by first venting at 100 ° C. under vacuum, then gelling at excess pressure and finally curing at normal pressure and 140 ° C.
