Definitions
- the subject invention relates to a continuous drill ladder consisting of a plurality of individual, electrically insulated conductor part, and a method for producing such a drill guide.
- Known manner occur in transformers especially at the outer coils of the winding electromagnetic fields (transverse fields), which induce eddy currents in the winding conductors, which lead to eddy current losses. Eddy current losses reduce the efficiency of the transformer, but also lead to locally undesirable high temperatures, which in turn can lead to damage to the winding insulation. Through the use of known continuous twisted conductors such eddy current losses can be reduced.
- Drill ladders consist of a bundle of individual, insulated individual conductors, which are individually twisted against each other, e.g. according to the Roebel principle.
- Such continuous drill conductors are e.g. known from EP 746 861 B1 and are thereby machined and automated produced with lengths up to 2000m and wound up for shipping on drums.
- Automated twisting tools for making such twisted ladders are e.g. from DE 100 26 455 A1 or DE 100 27 564 A1.
- Drill ladder are characterized in particular by the fact that they are sufficiently bend soft to be wound for the production of windings can. Furthermore, through the use of a drill guide, an increased copper cross-section can be crossed out.
- Roebel rods it is already known from AT 309 590 B to provide the twist in such a way that always two adjacent individual conductors are twisted together.
- Roebel rods which are still mainly manufac- tured manually by manually twisting single-length individual wires on special workbenches, can be easily made in this way, even if two adjacent parts are twisted together.
- Roebel bars are not wound, but it is "built" of several Roebel bars a winding by the ends of the Roebel bars are connected accordingly.
- This object is achieved according to the invention in that in each case two or more sub-conductors arranged next to one another and / or one above the other are combined to form a sub-conductor group and are twisted together. Because now not a single conductor is twisted, but always a subconductor consisting of several individual sub-conductors, the vortex power losses are further reduced, since the required copper cross-section of the individual conductor is electrically divided. Thus, the cross section of a single subconductor is reduced, whereby less eddy currents are induced by the electro-magnetic fields occurring and thus the eddy current losses can be reduced in a transformer using the drill guide according to the invention.
- Fig. 5 shows a cross section through such a drill wire
- Fig. 6 shows a further embodiment of a drill according to the invention.
- a known drill conductor 1 consisting of a number of electrically insulated partial conductors 2, which are arranged in two partial conductor stacks 3.
- the sub-conductors 2 are known to be twisted so that they change from the top to the bottom layer.
- a wrap 4 may be provided by a woven tape, a paper strip or the like.
- FIG. 2 An inventive drill 10 is shown in Fig. 2, which consists of a plurality of individual electrically isolated part conductors 1 1.
- this drill wire 10 in each case two adjacent sub-conductors 1 1 are combined to form a sub-conductor group 12.
- “Side by side” means that the sub-conductors 11 are arranged adjacent to each other on their narrow side surface twisted and not a single conductor like bis- forth in the art. such conductor group 12, more than two individual conductor 1 1 may include it.
- a cross section through such a drill head 10 having seven conductor groups 12 ⁇ to 12 7, consisting of two individual juxtaposed subconductors 11 are shown in Fig. 3.
- the subconductor bundle can be surrounded again with a winding 13, eg for the protection of the subconductors 11 during transport or for stabilizing the subconductor bundle.
- two individual sub-conductors 11 are arranged one above the other and combined to form a sub-conductor group 12, which in turn is twisted.
- "Superimposed” here means that the sub-conductors 1 1 are arranged adjacent to one another on their broad side surface.
- Such a sub-conductor group 12 may also comprise more than two individual sub-conductors 1 1 arranged one above the other, a cross-section through such a twisted conductor 10 having five sub-conductor groups 12T to 12 5 consisting of two individual sub-conductors 1 1 arranged one above the other.
- the subconductor bundle can again be surrounded by a winding 13, for example for protecting the subconductor 11 during transport or for stabilizing the subconductor bundle.
- subconductor group 12 from a plurality of subconductors 11 arranged next to one another and above one another, as indicated in FIG. 6, in which case again the entire subconductor group 12 is twisted.
- four individual sub-conductors 1 1 to a sub-conductor group 12- ⁇ to 12 5 are arranged side by side and one above the other.
