Definitions
- the invention relates to a glow protection for electrical machines.
- a glow protection usually has a fabric or a fleece.
- the smoldering protection can also be produced, for example, by a chemical reduction process, in the US. -PS 3,639,113.
- a further disadvantage of the glow protection according to the prior art is that the glow protection which is to be applied to the insulated electrical conductor of an electrical machine has hardened, but has not hardened. During the impregnation process of the electrical machine, also called VPI (Vacuum Pressure Impregnation) process, the hardened glow protection is influenced. The electrical conductivity of the glow protection according to the prior art can thus disadvantageously change.
- VPI Vauum Pressure Impregnation
- the glasses for the external glow protection as for the glasses for the final glow protection. Therefore the glass systems have to be chosen very carefully and the ratio of oxidized species / reduced species has to be adjusted.
- the thermal stability, the thermal thermal conductivity and the electrical properties are the thermal stability, the thermal thermal conductivity and the electrical properties.
- the ozone generated by partial discharge destroys both the soot or graphite, which is present in the organic resin, so that the conductivity of the glow protection is reduced, as well as the organic resin itself, so that it dissolves more and more and leads to a destruction of the Glow protection comes, whereby the glow protection consists of the gas fabric, the organic resin and the substances contained in it to adjust the electrical conductivity.
- the glow protection can, for example, be produced entirely from electrically conductive fibers and or threads, but also as a combination between electrically conductive fibers or threads and electrically non-conductive fibers or threads. In addition to changing the concentration of the materials used for the electrical conductivity, this creates a further possibility of adjusting the electrical conductivity of the glow protection. These options for setting the electrical conductivity are much simpler and cheaper than with doping.
- FIG. 2 shows the exit of a conductor from a stator laminated core
- FIG. 3 shows the dependence of the conductivity on the concentration of electrically conductive substances
- FIG. 4 shows two examples of a fabric.
- the illustration according to FIG. 2 shows in detail the transition of the copper conductor 3 from the stator core 1 into the air 16.
- the copper conductor 3 has a conductive insulation 7 as well also an external glow protection 5 and an end glow protection 4.
- the two glow protectors meet at connection 6.
- the step connection between the external glow protection 5 and the end glow protection 4 results from the fact that the glow protection is advantageously wound as a tape overlapping the conductor insulation of the copper conductor, so that the glow protection is located on the conductor insulation 7 in two layers, for example.
- other winding options are also possible, which lead to a single-layer or multi-layer winding by a tape.
- the illustration according to FIG. 4 shows two fabrics 40, 41.
- the fabric 40 is a plain weave.
- the fabric 41 is a body bond. Both types of fabric are examples of both a fabric that serves as a carrier material for a coating serves to understand, as well as an example of a fabric whose threads are coated.
