Definitions
- the invention relates to a method for producing an insulated electrical conductor with at least one location to be kept clear of the insulation, wherein the conductor including the areas to be kept open is initially surrounded by a liquid, electrically non-conductive connection means, in particular an epoxy resin, and the liquid, electrically non-conductive connecting means after its solidification forms the insulation. Furthermore, the invention relates to a liquid release agent for serving for electrical insulation of conductors and / or connecting individual conductors to a conductor connecting means, in particular epoxy resin, for selective and spatially defined prevention of the bonding effect of the bonding agent on the head.
- 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 multiple individual conductors existing twisted conductors for the winding arrangement of an electric machine is therefore advantageous because the construction of the drill wire substantially reduces the stray field losses during operation of the transformer.
- Exemplary describes the DE 102 24 587 A1 a potting compound which consists of a base component and at least two additives, wherein the additives are fused silica as the first additive.
- a second additive short-fiber glass fiber materials and / or mineral fibers or quartz powder are used.
- DE 299 15 252 describes an electrical cable wherein the electrical shield and the cable sheath are separated by a thin, separate separation layer.
- DE 31 44 337 describes a method for producing a power line, with a release agent which is arranged in the form of a release film between insulation and an outer conductive layer.
- the release agent can be supplied with liquid pressure and is evenly distributed.
- the separating layer allows complete stripping of the outer layer.
- a disadvantage of all previous methods in the prior art is that after curing of the epoxy resin - and thus the stiffening of the form of the conductor certain parts of the winding arrangements can not be bent. A change in shape of the winding arrangement or of certain points of the conductor of the winding arrangement necessary after the curing of the casting resin is no longer possible according to the prior art. Furthermore, 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 curing of the epoxy resin by a complex removal of the cured, insulating bonding agent from the conductor can be produced. In particular, 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 toxic gases and toxic vapors produced by the evaporation of the epoxy resin must be collected and then disposed of at a high cost.
- the epoxy resin layer burns off not only in the area of the desired terminal contact point, but also in the surrounding areas, which then subsequently have to be costly coated by hand and thus reinsulated.
- the high temperatures may 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 to produce an insulated electrical conductor with at least one to be kept free of insulation, the conductor being initially surrounded by a liquid, electrically-nonconductive connecting means, which does not have the above-mentioned disadvantages of the prior art.
- a liquid release agent is applied to the vacant position of the conductor.
- the already applied on the ladder, uncured bonding agent in particular an epoxy resin, is still in a non-cured state - so-called B-state- and is still in a highly viscous form.
- the viscosity would decrease and the bonding agent flow or flow in a conductor in the interstices of the individual conductors of the conductor, whereby the individual conductors stick together and isolated from each other.
- the bonding agent would then stick together without the release agent and harden to a solid shape structure.
- the liquid connection means serves to insulate and / or connect individual conductors.
- Liquid release agent in the context of the present invention comprises a wide viscosity range from very low viscosities to viscosities which define a nearly pasty mass.
- the location to be kept free of the insulation does not encompass all points of a conductor on which a connection and / or electrical insulation of the conductor or of individual conductors after the application of the bonding agent is desired, for example because the vacant places still need to be bent or machined.
- the entire conductor is subsequently heated to solidify the bonding agent and the mixture of bonding agent and release agent.
- no bonding effect has occurred between the individual conductors, since the resulting mixture has prevented this.
- the liquid release agent diffuses through the uncured bonding agent and forms a mixture with altered chemical-physical properties compared to the exclusive uncured bonding agent.
- an exclusive coating of the mixture has formed around the conductor after the curing of the bonding agent.
- the individual conductors are not glued together and / or isolated from each other according to this inventive method.
- the B-state connection means can not penetrate into the interstices of the individual conductors in this procedure during the heating process and connect them together and / or isolate from each other.
- the liquid release agent prevented by the formation of the mixture, a transition of the liquid bonding agent as the highly viscous B-state until hardening and thus fix this state of matter of the bonding agent.
- the liquid release agent it is preferable for the liquid release agent to be sprayed onto the conductor in the area of the location to be kept free of the insulation and / or the location of the conductor to be kept clear of the insulation is immersed in the liquid release agent.
- the liquid release agent For areas of the conductor which are to be kept free over a large area, it is advisable to immerse the corresponding points of the conductor in the liquid release agent.
- spraying or brushing onto the liquid release agent is to be preferred over the point of the conductor to be kept free of the insulation.
- the pressing of the liquid release agent under high pressure between the individual conductors is suitable as a type of application, wherein 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 risk of segregation of the resulting mixture is thus prevented and in the subsequent actual heating and curing it does not lead to a flow of no longer mixed Vietnamesesstoffan negligence. Especially in the case of twisted ladders, there is a risk that, without predrying of the resulting mixture, the mixture could flow into the intermediate spaces between the individual conductors and cause them to stick together.
- the liquid release agent contains polyvinyl alcohol.
- the release agent contains as a base compound long-chain hydrocarbon mixtures.
- all oils and oil mixtures used in transformer construction are used as long-chain hydrocarbon mixtures, since these are already used have been used for decades in their chemical-physical compatibility in transformer construction and therefore can be safely used in the context of the method according to the invention.
- liquid release agent contains alcohol portions in the form of a primary, secondary or tertiary alcohol or an alcohol mixture.
- the liquid release agent contains a filler based on a polysaccharide, which is present in a particle size of 1 .mu.m to 500 .mu.m, preferably from 30 .mu.m to 90 .mu.m.
- a preferred mixing ratio of polyvinyl alcohol or lanbgkettigen hydrocarbon mixtures and water of 1: 5 to 1:20 Alcohol is added to the release agent as a solvent, and according to the desired solvent properties, the alcohol content of the mixing ratio polyvinyl alcohol / water can vary greatly.
- alcohol in proportions of 1: 1 to 5: 1 relative to the base compound of polyvinyl alcohol or long-chain hydrocarbon mixtures is added to the polyvinyl alcohol / water mixture or the long-chain hydrocarbon mixture / water mixture.
- a ratio of the liquid mixture to the solid filler is from 10% by volume to 70% by volume.
- a liquid release agent for a connecting means for electrical insulation of conductors Particularly in the case of twisted ladders, the individual conductors are connected to one another by the connecting means and are electrically insulated from one another.
- the release agent contains the following components: polyvinyl alcohol, water, alcohol and a filler based on a polysaccharide.
- a mixing ratio of the polyvinyl alcohol and the water of 1: 1 to 1:20 is preferred.
- Alcohol is added in proportions of 1: 1 to 5: 1 relative to the polyvinyl alcohol to the polyvinyl alcohol / water mixture.
- the filler is present in a preferred grain size of from 1 ⁇ m to 500 ⁇ m, preferably from 30 ⁇ m to 90 ⁇ m.
- the ratio of the liquid mixture to the solid filler is preferably 10% -70%.
- the liquid release agent consists of long-chain hydrocarbon mixtures having a boiling point between 80 ° C and 300 ° C, water, alcohol and a filler based on a polysaccharide.
- long-chain hydrocarbon mixtures all oils and oil mixtures used in transformer construction are preferably used, since these can be safely used as a basis for the release agent according to the invention.
- a mixing ratio of the hydrocarbon mixture and the water of 1: 1 to 1:20 is preferred.
- Alcohol is added in proportions of 1: 1 to 5: 1 relative to the hydrocarbon mixture to the hydrocarbon / water mixture.
