Definitions
- the invention relates to a method for producing an electrical conductor provided with an insulation with at least one location to be kept free of the insulation, wherein the conductor, including the areas to be kept free, is initially provided with a liquid, electrically nonconductive compound, in particular a Epoxy resin, surrounded and the liquid, electrically-non-conductive bonding agent after its solidification forms the insulation. Furthermore, the invention relates to a liquid release agent for a connection means, in particular epoxy resin, used for the electrical insulation of conductors and / or for connecting individual conductors to a conductor for the selective and spatially defined prevention of the bonding effect of the bonding agent on the connector Ladder.
- epoxy resin in the case of twisted conductors opens up the possibility of forming a sufficient electrical insulating layer between the individual conductors between the individual conductors on the basis of its electrical properties after curing.
- the use of drill conductors consisting of a plurality of individual conductors for the winding arrangement of an electrical machine is therefore advantageous since the construction of the drill guide substantially reduces the stray field losses during operation of the transformer.
- DE 34 19 336 A2 discloses a method for
- the epoxy resins used in this case are usually enriched by additional chemical components or solid fillers in order to increase the bonding and / or insulating properties of the epoxy resin between the individual conductors.
- DE 102 24 587 A1 describes a potting compound which comprises a base component and at least two additives, with the additives being fused silica as the first additive.
- a second additive ⁇ the short fiber glass fiber materials and / or mineral fibers or quartz powder used.
- the epoxy resin cured as an insulator between the individual conductors also prevents the possibility of an electrical contact between the individual conductors for specific position of the winding arrangements or the conductors used, which again only after the curing of the epoxy resin by a complex removal of the cured, insulating bonding agent from the conductor can be produced.
- the production of a connection contact of the electrical machine with the external electrical supply voltage lines requires complete contacting of all individual conductors with the external supply connection. This is done so far only with a high cost according to the prior art.
- Another alternative according to the prior art is the burning of the cured epoxy resin coating from the point to be contacted of the conductor of the winding arrangement and the associated spaces between the individual conductors of the point to be contacted of the conductor.
- the epoxy resin fung resulting toxic gases and vapors toxi ⁇ rule must be collected and then disposed of at great expense.
- the high temperatures can also adversely affect the electrical and mechanical properties of the individual conductors-and thus of the conductor-due to the high temperatures during burning.
- Object of the present invention is therefore a quick and easy way of producing a-regulation with an iso ⁇ provided with at least one electrical conductor to be kept free from the insulation, wherein the conductor is initially surrounded by a liquid, electrically non-conductive Ver ⁇ binding agent to provide, which does not have the above ge ⁇ called disadvantages of the prior art.
- the viscosity would decrease and the croqusmit ⁇ tel melt glue ter each other whereby the Einzellei ⁇ or in a twisted conductor in the spaces between the individual conductors of the conductor to flow, and insulated from each other are.
- the bonding agent would without the release agent then stick together and harden to a solid form ⁇ structure.
- the liquid connection means serves to insulate and / or connect individual conductors.
- Liquid release agent in the sense of the present invention encompasses a large viscosity range from very low viscosities to viscosities which define an almost pasty mass.
- the location to be kept free of the insulation comprises all points of a conductor on which a connection and / or electrical insulation of the conductor or individual conductors does not occur after the application of the bonding agent is desired, for example, since the vacant places still gebo ⁇ gene or must be mechanically processed.
- Separating agent diffuses through the uncured Verbin ⁇ tion medium and forms a mixture with altered chemisch ⁇ physical properties in comparison to exclusively non-cured bonding agent.
- an exclusive coating of the mixture has formed around the conductor after the curing of the bonding agent.
- the Verbin ⁇ located in the B-stage dung medium can not penetrate into the spaces between the individual conductors and isolate these interconnect and / or against each other in this procedure during the Erisser ⁇ mung process.
- the liquid release agent prevents by the formation of the mixture a transition of the liquid Ver ⁇ bonding agent as the highly viscous B-state until hardening ⁇ off and thus fix this state of the substance Verbin ⁇ tion medium.
- the liquid release agent for the purposes of the present invention, preference is given to spraying the liquid release agent on the conductor in the area of the location to be freed from the insulation and / or the location of the conductor to be kept clear of the insulation is immersed in the liquid release agent.
- the immersion of the corresponding points of the conductor offers in the liquid release agent.
- spraying or painting on the liquid release agent of the kept free of the Isolie ⁇ tion point is preferable of the conductor.
- the pressing of the liquid release agent under high pressure between see the single conductor lends itself as a type of application, where ⁇ in this case the liquid release agent is present in the form of a pasty mass and is pressed under high pressure.
- a further embodiment of the method is that the liquid release agent is dried after application to the not yet cured bonding agent. This process step ensures that the liquid release agent applied to the liquid bonding agent pre-fixes the material state of the resulting mixture. The danger of a demixing of the resulting
- the liquid release agent contains polyvinyl alcohol.
- the release agent contains as a basic compound long-chain hydrocarbon mixtures.
- long-chain hydrocarbon mixtures all oils and oil mixtures used in Transforma ⁇ gate construction, as these loading have been in use for decades in terms of their chemical-physical compatibility in transformer construction and can therefore be safely used in the context of the method according to the invention.
