Definitions

  • insulation system refers to: an insulation which basically comprises a main insulation, the AGS, EGS, and optionally the IPS.
  • the present invention relates to a novel formulation for a casting compound for casting to produce the main insulation or parts of the main insulation, which, quite surprisingly, has shown in tests that instead of the usual winding tape insulation, the main insulation can be produced by simple encapsulation, even in the high-voltage range.
  • a “resin-hardener mixture” refers to a resin mixture in which a hardener is present, for example an anhydride hardener, which accelerates but does not necessarily initiate the polymerization. This is formed when the monomer / oligomeric units are crosslinked to form the polymer, that is to say both the gelation as well as the hardening of the potting compound, built into the polymer chain or the polymer network.
  • This hardener component can then be detected in the finished insulation system using spectroscopic methods by means of which functional groups in the polymer chain, or the polymer network in question, can be identified .
  • the potting can be chemically separated by a high-performance liquid chromatography "HPLC" and examined by means of an element analysis. If necessary, the potting - for example in an electric rotating machine - can be superficially using ATR-IR spectroscopy After electrical aging, the silicon-oxygen-based resin component should basically be visualized via a glazed, silicon-rich layer in the energy-dispersive element analysis or in the ESCA analysis.
  • the catalyst merely serves to activate the monomeric or oligomeric compounds present in the storage-stable, liquid, neither gelled nor hardened, resin, or the so-called casting compound, in such a way that they are combined with molecules of the same or a different one in the casting compound existing for the polymerization, react, for example, the hardener or the second resin components te A or B to the polymer.
  • the catalyst per se generally does not become part of the repeating units that build up into the polymer network.
  • R can be the same or different and stand for the following groups:
  • R stands for all types of organic radicals which are suitable for curing and / or crosslinking to an insulation material which can be used for an insulation system.
  • R stands for all types of radicals which, in particular, can lead to saturated and / or unsaturated compounds
  • R be:
  • R aryl, alkyl, alkoxy, alkenyl, alkynyl, heterocyclic radicals which also contain nitrogen, amine, carboxyl, oxygen and / or sulfur-substituted aryls and / or alkyls, as well as any combination of several of the radicals mentioned in a radical.
  • R can be the same or different and stand for the following groups:
  • Alkyl for example methyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, pentyl, isopentyl, cyclopentyl and all other analogs up to dodecyl, ie the homologue with 12 carbon atoms;
  • Heterocycles in particular sulfur-containing heterocycles such as thiophene, tetrahydrothiophene, 1,4-thioxane and homologs and / or derivatives thereof,
  • - nitrogen-containing heterocycles such as -CN, -CNO, -CNS, - N3 (Azid) etc.
  • glycidyl-based and / or epoxy-terminated aryl and / or alkyl siloxanes and / or glycidyl-based and / or epoxy-terminated aryl and / or alkyl hydrocarbon compounds such as, for example, glycidoxy functionalized glycidoxy-terminated siloxanes and / or hydrocarbons, for example compounds containing oxirane groups such as glycidyl ethers.
  • Suitable hardeners that is to say a polymerizable resin component
  • anhydrides in particular acid anhydrides, such as phthalic anhydrides, which have already been successfully used in insulation materials in many cases.
  • acid anhydrides such as phthalic anhydrides
  • This new manufacturing process for the production of the main insulation or parts of a main insulation of an insulation system can be carried out without winding, in particular without winding by hand, of a winding tape. This is the crucial point for a) compacting the new insulation systems, b) accelerating the manufacturing process and c) the possibility of fully automating the manufacturing process. For example, a potting or coating can be produced automatically.
