Definitions
- the present invention relates to a laminated core assembly of an electric generator, in particular of a generator of a gearless wind turbine.
- the present invention relates to an electric generator, in particular a gearless wind turbine and a wind turbine.
- the present invention relates to a method for producing a laminated core assembly.
- a pole piece generally serves to guide a magnetic field and to let out and distribute the magnetic field lines in a defined shape.
- Such a pole piece consists of a material with a high permeability.
- Pole shoes are arranged, for example, in an electric generator of a gearless wind power plant in the stator and / or in the rotor of the generator.
- a pole shoe sheet package which is constructed to avoid or at least reduce eddy currents from many individual sheet metal laminations insulated from one another is understood below. The same applies to laminated cores of a stator, namely in particular the webs in the stator between the grooves which receive a winding.
- the excitation coils are distributed separately on individual coil cores over the circumference. It is therefore an object of the present invention to remedy, at least reduce, at least one of the problems described above.
- At least an alternative solution should be proposed.
- Such a laminated core assembly of an electric generator, in particular a generator of a gearless wind turbine, has at least one laminated core, in particular a Polschuhblechb, at least one arranged around the laminated core winding and arranged between the laminated core and the Wcklung electrical insulation means.
- the insulating means for conducting the heat generated in the winding on a composite material is understood below a material of two or more interconnected materials.
- the composite material may comprise a fiber composite material or fiber composite plastic, which consists of a bedding matrix and reinforcing fibers.
- fibers for example, glass fibers, aramid fibers or natural fibers such as cellulose fibers can be used.
- the fibers are preferably in the form of a textile surface fabric, ie in the form of a nonwoven. Alternatively, the fibers may also be in the form of a woven or laid fabric.
- the matrix may comprise, for example, thermosets such as synthetic resins, elastomers or thermoplastics. Preferably, epoxy resins or silicone resins are used.
- a laminated core assembly includes a laminated core and other elements.
- the laminated core may be a Polschuhblechb a rotor or stator lamination stack of a stator. All explanations given in connection with pole shoe lamination packages apply analogously to stator lamination packages and vice versa.
- the resin is preferably in a so-called B-state, ie in a state in which the material has already been treated with heat, for example, but has not undergone the final treatment. The resin is therefore still reactive and can be treated accordingly.
- the composite material may comprise a particle composite material.
- a particle composite material is understood below to mean a composite material in whose matrix particles of other elements are incorporated. Such elements may include, for example, ceramic particles, particles of refractory or other metals or particles of hard materials.
- the insulating means comprises a paper, in particular an aramid paper, and a further material layer, in particular a glass fiber fleece, which has been impregnated on the paper and which has been impregnated on the paper.
- the paper and the resin-impregnated material layer together form a composite material.
- Such insulation means are electrically non-conductive and thus serve for electrical insulation.
- they are thermally highly conductive and can thus at least partially dissipate the heat generated in the winding in, for example, the laminated core.
- the additional application of, for example, a glass fiber fleece impregnated with resin avoids, at least reduces, air pockets. The good suction effect of the fleece produces an optimal capillary action, ie a filling of the cavities.
- the strength of the composite material is increased and a firm (more intimate) adhesive bond between the insulation paper and the adjacent laminated core produced.
- a part of the matrix can settle into small pores and joints, in particular in pores and joints on the surface of the laminated core. As a result, air pockets can be avoided and thereby the heat transfer from the winding to the laminated core can be improved.
- the composite it is possible to provide a sufficient amount of the matrix that insulation paper could not provide.
- Such a nonwoven may comprise various fibers. Preferably, glass fibers are used. Alternatively, fibers of cellulose, polyamide, polyester, aramid and the like can be used. By using such a nonwoven fabric, the total thickness of the composite material can be kept very low. Such a nonwoven is in a thickness range of a few ⁇ up to 50 ⁇ to 100 ⁇ . Such a thin material leads to an increase in the thermal conductivity compared to thicker materials. Alternatively, a lacquer can be used as the insulating agent, on which only a nonwoven soaked in resin is arranged. The paper is omitted. The advantage here is that thereby the material thickness is reduced and thus the thermal conductivity is increased.
- the insulating means comprises ceramic particles.
- ceramic particles are added to the matrix material as nanoparticles.
- the ceramic particles support the electrical insulation as well as the heat conduction from the winding to, for example, the laminated core.
- the ceramic particles support the flow process.
- a ceramic-particle-provided matrix material in particular a resin, for example, applied to a paper to increase the thermal conductivity.
- the ceramic particles can be formed, for example, from aluminum oxide, silicon carbide, zirconium oxide, silicon dioxide and the like.
- mica such as, for example, real mica, sparks or mica, may be added to the resin.
- the at least one laminated core has a cooling body that completely or partially surrounds the laminated core, wherein the cooling body is arranged between the laminated core and the core.
- the cooling body is arranged between the laminated core and the core.
- Such a heat sink is preferably designed with a smooth surface. Thereby, a material layer, such as the paper, may be omitted from the insulating means and, for example, a resin-soaked non-woven fabric may be used.
- the heat sink has connections, wherein the connections are completely or partially integrated in a laminated core. Such an integration takes place, for example, so that corners of the laminated core are recessed and the connections are provided in this area and the recessed or saved space is thus used efficiently.
- the terminals can thus take the place of corners or edges of a Polschuhblechpers and thereby be integrated into the shape of the laminated core assembly.
- the invention comprises an electric generator, in particular a gearless wind turbine, with a rotor and a stator.
- the rotor and / or stator has at least one laminated core arrangement.
- the rotor has a rotor belt and / or the stator a stator belt, each having a cooling channel for transporting a cooling medium, in particular a cooling liquid having.
- the term rotor belt denotes a circumferential support ring of the rotor with a defined radius, which carries the laminated cores, namely here the Polschuhblechpakte.
- stator belt accordingly designates a circumferential supporting ring of the rotor with a defined radius, which may also be referred to as a stator ring.
- the heat generated mainly by the winding is at least partially passed through the insulating means in the laminated core and from there into the cooling channel.
- a cooling channel is preferably flowed through by a cooling liquid, in particular water with a proportion of glycol.
- the cooling channel is part of a closed cooling circuit in which the heated by the heat dissipation on the laminated core cooling liquid is cooled again.
- the rotor and / or stator of the electric generator each comprise at least two laminated cores.
- each laminated core on one or one of the heat sink and all heat sinks are functionally connected to each other via at least one cooling channel.
- the heat sink is located between the laminated core and Wcklung and thus cools the laminated core directly.
- the rotor of the electric generator has an emergency air cooling.
- air is forced into the generator by means of a blower in a stator bell and can there be guided, inter alia, for cooling by the generator air gap between rotor and stator.
- the fan is operated as slowly as possible in the normal operating state. In case of failure of the regular cooling system, the fan is switched up to supply more cooling air.
- the invention proposes a wind turbine with an electric generator according to the invention.
- the wind turbine comprises a pump operatively connected to the at least one cooling channel and a cooler, in particular an external cooler for cooling the cooling medium.
- the pump pumps the coolant through the cooling circuit.
- the cooling medium is thereby preferably passed to a recooler, in which the cooling medium is cooled and is pumped via the connection points back into the cooling channel.
- the outdoor cooler is arranged so that it is cooled by a natural air flow.
- Such an external cooler is located in or on the nacelle of the wind energy plant, preferably on at least one outer side of the nacelle or on or in the spinner.
- the outer cooler preferably has finned tubes or rib-like cooling elements which have a sufficiently large surface to ensure a required heat dissipation.
- an artificial air inflow for example via a fan for cooling can be used.
- the method comprises the following steps:
- the composite material is wound in a preheated state on the laminated cores and then, preferably the entire generator, for example soaked in resin. As a result, air pockets are avoided, at least reduced.
- the generator and / or the bath in which it is soaked preferably has a temperature of about 120 ° C - 160 ° C, in particular about 150 ° C.
- the composite material preferably has a paper impregnated with a resin and / or a resin-soaked nonwoven. This improves the flow properties of the resin.
- ceramic particles are supplied to the composite material. These are preferably introduced into the resin after or before the arrangement of the composite material on the laminated core, preferably lubricated similarly to a paste. As a result, air pockets are avoided, at least reduced. Or the ceramic particles are added to the composite material in advance, in particular together with the matrix.
- the composite material is cured by heat treatment, preferably by annealing.
- the composite could be cured by photohardening.
- Fig. 1 shows a simplified representation of a wind turbine.
- Fig. 2 shows an embodiment of two laminated core assemblies.
- FIG. 3 shows a detail from FIG. 2.
- FIG. 4 shows a sectional view from FIG. 2.
- FIG. 1 shows a highly simplified representation of a wind energy plant, which is denoted by the reference numeral 100 in its entirety.
- the tower 12 carries the gondola 16 (alternatively, the term nacelle can also be used for the gondola).
- the nacelle 16 is mounted on the head of the tower 12 using an azimuth bearing (not shown) so that a wind direction tracking can be realized via azimuth drives (also not shown).
- the transition between gondola 16 and tower 12 is covered by a gondola apron 14 and protected against the weather.
- the nacelle 16 also includes the hub (also not shown) to which the rotor blades 24 are attached.
- the rotor blades 24 set the hub (with the spinner, the front part of the nacelle 16) in rotation. This rotational movement is transmitted to the rotor of the generator, so that the wind turbine 10 generates electrical energy at a sufficient Wnd nie.
- Fig. 2 shows two laminated core assemblies, namely two Polschuhan everen 1, each with a laminated core, namely Polschuhblechpers 1 1 and each of a winding 4, which are arranged on a rotor 2, schematically. It is shown by the rotor 2 only a section.
- the rotor 2 has a support ring, which is referred to as a rotor belt 3 and carries the Polschuhblechwovene 1 1.
- the rotor belt comprises a, not shown, radially encircling cooling channel. To illustrate the direction of the heat conduction 5 is illustrated with arrows. Accordingly, the heat generated in the winding 4 is passed through the Polschuhblechvolu 1 1 in the rotor belt 3.
- the cooling channel arranged in the rotor belt 3 is used.
- the cooling channel is traversed by a cooling medium, which is part of a closed cooling circuit. From there, the heated cooling medium is pumped into a recooler and pumped again after heat transfer into the cooling channel.
- Fig. 3 shows a detail of Fig. 2 with the reference B, which illustrates an enlarged portion of the pole piece assembly 1, in which the area between the Polschuhblechvers 1 1 and the winding 4 is enlarged and shown partially illustrative.
- a composite material 10 is shown as an example of an insulating means comprising a paper 7, a nonwoven 9 and a resin 8.
- the individual components are connected to form a component that can be applied as a film in the construction of laminated core assemblies, such as the pole piece 1. It can be seen that the resin 8 is in the interstices of the winding 4 and thus avoids air pockets, at least reduced. Even unevenness of the surface of the Polschuhblechpers 1 1, which is composed of various Polschuhblechen (not shown here) are compensated.
- FIG. 4 shows a section of a sectional view of a pole piece arrangement 1.
- the individual Polschuhbleche 6 and laminations 6 of the Polschuhblechpers 1 1 to recognize.
- the winding 4 and the paper 7, the web 9 and the resin 8 can be seen.
- the circumference of the Polschuhblechwoven 1 1 - and thus the surfaces according to the sectional view of Figure 4 - has by the individual laminations 6 no smooth surface. It can joints or pores by unevenness of the edges 20 or by small offset between the Polschuhblechen 6 occur, through which the risk of air bubbles and thus the risk of poor thermal conductivity results. Therefore, the paper 7 and the nonwoven 9 are used.
- the nonwoven can absorb and provide a large amount of resin.
- FIGS. 3 and 4 each show sections of FIG. 2 schematically. There may be variations in details between Figures 2, 3 and 4.
