Definitions
- the invention relates to a novel formulation for an insulation system which exhibits higher erosion resistance and can be used as a casting and / or pressing resin as conductor and / or wall insulation for current-carrying conductors in generators, motors and / or rotating machines.
- the insulation system has to isolate the task of electrical conductors (wires, coils, rods) permanently against each other and against the stator core or the surrounding ⁇ bung.
- electrical conductors wires, coils, rods
- a distinction is the insulation between conductor elements (conductor insulation) between the conductors or windings (conductor and / or turn insulation) and between the conductor and ground potential in the groove and winding area (Hauptisolie ⁇ tion).
- the thickness of the main insulation is adapted to both the nominal voltage of the machine, as well as the operating andTECHsbe ⁇ conditions.
- the object of the present invention is therefore to provide a fracture-mechanically resilient high-voltage insulation system which exhibits improved erosion stability.
- a solution to the problem and object of the present invention is therefore a formulation for an insulating system, a base resin with one or more isotropic spherical filler components, wherein the filler components are nanoparticles, inorganic particles and organic particles comprise and in a total proportion of up to 25% by weight be in the Formulie ⁇ tion.
- the filler components are nanoparticles, inorganic particles and organic particles comprise and in a total proportion of up to 25% by weight be in the Formulie ⁇ tion.
- the base resin is selected from the group comprising Thermoplas ⁇ th, thermosets and / or elastomers.
- the base resin may be selected from the group consisting of UV, cold or heat curing, phthalic anhydride and / or amine curing resin, in particular, for example, an epoxy resin.
- the base resin is a diglycidyl ether, for example a bisphenol A or bisphenol F diglycidyl ether or a cycloaliphatic epoxy resin or a phenolic novolak.
- the base resin be selected from the group of polyurethanes, the
- the isotropic fillers mentioned can be selected from the group of inorganic particles, for example the metallic, the metal and / or semimetal oxide particles.
- the particles of the filler and from ke ⁇ ramischen materials may be as talloxid example, of a metal or a metal oxide such as alumina and / or silicon dioxide.
- the inorganic nano-filler particles give the Formu ⁇ -regulation the required erosion resistance.
- the particles of the filler may also be selected from the group of organic compounds, for example, it may be polymeric nanoparticles such as styrene, butadiene, etc.
- the organic nanofiller particles impart some ductility to the formulation.
- the organic fraction of the nanofiller particles is kept as low as possible.
- CS ie core-shell particles
- nanofiller particles are particles with a shell and a core of different materials.
- Core-shell particles generally show a layer structure of different materials that has a radial gradient.
- a suitable surface modification provides a geeig ⁇ designated connection of the nano-filler particles to the matrix.
- the surface modification may be in the form of a coating, for example.
- the formulation is preferably used as a low-viscosity and / or isotropic material, wherein the nanofiller particles are present in dimensions in the range from 5 to 500 nm, in particular from 7 to 350 nm and very preferably in the range from 8 to 300 nm.
- Silica-based and / or based on inorganic ⁇ organic materials such as styrene-butadiene and / or
- a nanofiller fraction of inorganic-organic material in an amount of between 1 and 10% by weight, more preferably in an amount in the range of 3 to 8% by weight and particularly preferably 4 to 6% by weight.
- organic fillers were incorporated into the formulation.
- FIG. 2 shows the test results of Erosionsresis ⁇ tence again.
- FIG. 2 shows a decrease in erosion resistance in the course of successively increased proportions by weight of organic nanofiller particles.
- Nanofiller particles act as barriers to the formation of the inorganic Fusion aggregates, whereby the mechanical stability of the passivation layer is markedly ge ⁇ ringer, especially the organic fillers are subject to partial discharge under stress of a material degradation.
- the passivation layer considered comprises silicon dioxide and siloxane-butadiene
- Nanofiller particles in a total weight fraction of 20% are understood to mean a material which, on the one hand, gives ductility and resistance to breakage due to its organic content of the formulation and, on the other hand, can form sinter bridges with the inorganic fusion aggregates of a passivation layer due to the inorganic content of the formulation.
- inorganic-organic material for a nanofiller particle is understood to mean a material which, on the one hand, gives ductility and resistance to breakage due to its organic content of the formulation and, on the other hand, can form sinter bridges with the inorganic fusion aggregates of a passivation layer due to the inorganic content of the formulation.
- different materials will be preferred, which are easily tested.
- a styrene-butadiene material and / or a siloxane-butadiene material may be used herein.
- Insbesonde re ⁇ a commercially available siloxane-butadiene copolymer has been successfully tested in an epoxy resin-based polymer.
- Anorga ⁇ cally-organic nanofiller particles such as the GE herein ⁇ showed siloxane-butadiene nanofiller particles is contained in sym-biotic manner in the Fusion aggregates Passi ⁇ multungs slaughter integrate, since they see through their inorganic content also via sintering bridges ensure sufficient Ver ⁇ compound of the entire passivation layer such as purely inorganic nanofiller particles.
- the formulation shows with the inorganic-organic Nano Shellstoff- particles have a much more compact and more homogeneous passivation layer approximately ⁇ than the formulation in which inorganic and organic nanofiller particles as separate fractions, that are present separately. It can be seen that over the inorganic portion of the
- Siloxane-butadiene nanofiller particles a symbiotic In ⁇ tegration of this filler fraction by means of sintered bridges in the inorganic fusion aggregates comprehensive Passivitations ⁇ layer takes place.
- a compact and homogeneous passivation layer is generated by erosion resistance of these filler fraction, wherein the organic particles are not subject to Materialde ⁇ gradation under partial discharge stress and somit- addition to the increased erosion resistance as well as a Break-mechanically resilient and ductile high-voltage insulator-polymer system is created.
- Hardener Methylhexahydrophthalic anhydride, ratio (resin to hardener) 1: 0.9;
- Accelerator N, -dimethylbenzylamine, accelerator content: 1% by weight,
