Definitions

  • the present invention relates to the field of electrical windings, in particularly rotor or stator windings of electric motors.
  • PCT patent application WO96 / 42089 discloses for example a conductor coated with an insulating layer whose resistance varies with voltage of excitement.
  • the examples of insulation layer described in this art document previous, are matrices comprising metallic oxides. This solution does not allow the evacuation of electrical charges formed during transients of voltage.
  • composite coatings such as describe in DE4438187 comprising a polymer matrix including mineral fillers with non-linear resistance such as zinc oxide or silicon carbide
  • Non-linear resistance material means a material of low conductivity in the absence of an electric field, the resistance of which is a non-function linear of the electric field to which said material is subjected or of the difference of potential, applied to said material. The resistance of such materials decreases when the tension applied to it increases.
  • the object of the present invention is to provide an electric winding having a coating of non-linear resistance composite material overcoming the above defects.
  • the invention relates to an electrical winding constituted by winding of an electrical conductor having a coating to form a a plurality of turns, said coating comprising a polymer matrix and at least one material having a nonlinear resistance characterized in that the material to nonlinear resistance is a doped or undoped conductive polymer.
  • the matrix and the conductive polymer use a common solvent.
  • the coating consists of a alternating layers of non-linear resistance materials, and layers insulating.
  • the coating consists of a inner and outer insulating layer and an intermediate layer of materials to nonlinear resistance.
  • the coating has a gradient of concentration of non-linear resistance materials.
  • the coating consists of a single layer chosen from materials with non-linear resistance.
  • the non-linear resistance material can be PANi and its derivatives.
  • the concentration of conductive polymer can be between 1 and 30% in volume.
  • the concentration of conductive polymer is between 15 and 18% by volume.
  • the non-linear resistance material may further comprise doped zinc oxide particles.
  • the conductive polymer is a polymer chosen from a polyaniline, the N-phenyl P-phenylene diamine, a polythiophene, a polyarylthiopene, a polypyrolle, a polyarylvinylene, a poly (P-phenylene sulfide), a poly (P-phenylene), a para-phenylene vinylene (PPV), their copolymers and their mixtures.
  • the first polymer is a self-doped copolymer chosen from a copolymer N-phenyl P-phenylene diamine with an amino-naphthalene sulphonic acid, a copolymer of aniline with an amino) naphthalene sulphonic acid, a copolymer of aniline with 3- (3-aminobenzyloxy) -1-propane sulfonic acid, a copolymer of laniline with 3- (2-aminophenoxy) -1-propane sulfonic acid, a copolymer of aniline with 4- (2) aminophenoxy) -1-butane sulfonic acid, a copolymer of aniline with 1-amino 2, 6-bis (4-sulfobutoxy) benzene, and their mixtures.
  • the synthesis of these copolymers is described in European patent EP-0 512 926 published November 11, 1992.
  • the dopant can be for example acid hydrochloric (HC1), Sulfuric acid (H2SO4), camphrosulphonic acid, or still a substituted sulfonic acid.
  • a patent published under the number FR2719595 describes crystalline compounds with ferromagnetic properties of inclusion of metal salts in copolymers the elementary motif of which includes a link of a first group of aminoaromatic compounds derived from 1-naphthylamine and oxidized forms and a link in a second group of amino aromatic compounds substituted, chosen from substituted lead compounds comprising at least two fused benzene rings, substituted polycyclic compounds comprising at least one aniline unit in their structure, compounds derived from aniline bearing a substituent linked to the nucleus by an ethynylidene or paraphenylene link and the corresponding oxidized compounds.
  • the winding according to the invention consists of a plurality of turns formed by winding a wire having a structure whose single figure represents a section view.
  • the wire consists of an unglazed conductive core (1) surrounded by a three-layer coating.
  • the first layer (2) is an insulation layer, for example a varnish insulation usually used for insulation of conductive wires.
  • the second layer (3) is a layer of non-resistant material linear.
  • the third outer layer (4) is like the inner layer (2) formed by an insulating varnish usually used for the insulation of conductive wires.
  • the intermediate layer (3) constitutes an equipotential screen ensuring the flow of charges forming during rapid transients, especially when the winding is supplied with high periodic voltages, whose signals have stiff fronts.
  • This intermediate layer has a high resistance when the field electric current resulting from the current flowing through the conductive wire (1) is low. On the other hand, when the electric field increases, this intermediate layer becomes conductive and contributes to limiting the risks of breakdown of the insulating layer.
  • the non-linear material is produced by a matrix containing a polymer conductor doped or not, in particular polyaniline at concentrations of the order from 1 to 30% by volume, and preferably of the order of 15 to 18%.
  • the non-linear material can be chosen from crystalline compounds, ferromagnetic properties of inclusion of metal salts in copolymers the elementary motif of which includes contiguous, a link in a first group of aminoaromatic compounds derived from 1-naphthylamine and oxidized forms and a link in a second group of amino aromatic compounds substituted chosen from substituted amine compounds comprising at least two fused benzene rings, substituted polycyclic compounds comprising at least one aniline unit in their structure, compounds derived from aniline bearing a substituent linked to the nucleus by an ethynylidene or para-phenylene link, and the corresponding oxide compounds.
  • the nonlinear material may further include oxide particles metals embedded in the matrix, in particular doped zinc oxide.
