Definitions
- the invention relates to a material for insulation system, an insulation system, a predominantlyglimmtik and an electric machine.
- the external potential control has the task to establish an electrical contact between the
- External corona protection as used for potential control by means of G-VPI processed machines, is shown.
- an insulating base winding 70 is applied from fine mica tape, which smooths the edge radii of the thin copper section conductor 40 and increases.
- a first graphite-containing Leitvliesband 100 is wound over this, which is connected via a contact strip 130 at only one point with the high voltage potential of the copper part conductor 40.
- An outer corona shield 110 made from a prior art material (conductive, flexible tape, especially from Krempel), an outermost divider 190 ', and an outer corona shield 200.
- An outer corona shield 140 interwoven in the outermost divider 190' connects inner 110 and outer 200 outer corona shields. The resulting when starting and stopping the generator
- Copper conductor bond and the insulation can after some operating time to local detachment of the insulating sleeve of Conduct ladder without igniting the dreaded partial discharges in the resulting columns.
- FIG. 1 shows an external potential control of a
- FIG. 1 Generator winding rod according to the prior art
- Figure 2 shows an inventive external potential control
- Figure 3 shows a generator.
- the invention consists in using hydrophobic material, in particular PTFE (Teflon) as insulation, in particular for such a high-voltage insulation system, wherein the insulation system is electrically conductive in layers
- the high voltage isolation system may be a simple system or a more complex system as in FIG.
- the invention will be explained only with reference to PTFE as an example of a hydrophobic material.
- the hydrophobic material or PTFE is designed to be electrically conductive.
- the PTFE is then a composite material.
- the fabric is preferably formed from fibers which comprise the electrically conductive insulation material, in particular PTFE.
- This fabric is preferably in tape form and is wound onto the surface to be insulated for application (see Figure 2).
- a perforated band in tissue form or the like
- a perforated membrane or a perforated scrim scrim as known from textile technology
- the high-voltage insulation system in the outer corona protection fibers or a fabric of PTFE, wherein to achieve the electrical conductivity and between the fabric-forming structures preferably a electrically conductive material, preferably graphite
- the AGS in the high-voltage insulation system in Figure 2 preferably comprises a fabric of PTFE, this being so
- tissue has pores that can be infiltrated as described above by the described method.
- Tissue acts and thus can be applied before curing.
- Plastic matrix has a different resistance value
- the objectives for the AGS-G according to the invention are:
- Separating layer which has a defined mechanical Decoupling realized without that it comes to changing the electrical resistance.
- This is to be realized by replacing the double layer gap mica by hydrophobic tissue types. This may be in particular a Teflon tissue.
- the structure is done in the following way:
- FIG. 3 shows by way of example a generator as
- Rotary machine arrangement in particular a
- the generator arrangement 2 has a housing 10.
- a housing 10 In the turbine-side end portion 6 is a
- Cooling device 12 is arranged. And that is in one
- Cooler head 14 which is a part of the housing 11, two coolers 16 and a compressor in the form of a blower 18 with a fan hub 20 arranged.
- the fan hub 20 is seated on a rotor 22 which extends along the longitudinal axis 3 through the
- Generator assembly 2 extends. Following the
- the stand 24 has a
- Stator winding with a turbine-side stator winding head 28A and with a pathogen-side stator winding head 28B on. Between the two stator winding heads 28A, 28B, a so-called laminated core 30 is arranged. Analogous to the stator 24, the rotor 22 has a turbine-side rotor winding head 32A and an exciter-side rotor winding head 32B.
- Power density is a cooling of the generator assembly 2 in the generator region 23 is necessary. A particularly high
- Cooling requirements here have the St Swickelkexcellent 28A, 28B, and the Läuferwickelkexcellent 32A, 32B.
- the Generator region 23 has this a cooling system 34 which is supplied by the cooling device 12 with cooling gas.
- the cooling system 34 has a number of cooling gas channels 36A, D, 48, via which the cooling gas is circulated.
- a first cooling gas channel 36A extends in the axial direction and is arranged between the stator 24 and the housing 10.
- a second cooling gas channel 36 B is formed by the air gap 26. Further extending in the axial direction
- Coolant gas channels 36C lead through the laminated core 30.
- a cooling gas channel 36D leads through it. The cooling gas flow in the generator region 23 and in the
- Cooling device 12 is indicated in each case by arrows, wherein the dashed arrows indicate the flow path of the cold
- Cooling gas and the solid arrows indicate the flow path of the heated cooling gas (hot gas).
- One partial flow serves for cooling the turbine-side stator winding head 28A and the other partial flow is forwarded via the cooling gas channel 36A to the exciter-side stator winding head 28B and split again. The one part is used to cool the
- St Sterwickelkopfs 28B and flows from there as hot gas on the air gap 26 back again.
- the other part is passed through the cooling gas channels 36 C of the laminated core 30 and exits in the turbine-side end portion 6 as hot gas and is the coolers 16, respectively.
- cooling gas is introduced into the cooling gas passage 36D of the rotor 22 from both the turbine-side end portion 6 and from the turbine-side end portion 6
- Partial flow is further passed through the rotor 22 in the cooling gas channel 36D, in such a way that the cooling gas from the two Läuferwickelköpfen 32A, 32B flows towards each other and is passed approximately in the central region 38 of the generator portion 23 in the air gap 26.
