Definitions

  • the present disclosure relates to a cable having a plurality of conductors, for example strands.
  • cable is generally referred to an insulating coated single or multi-core composite of wires (individual lines), which serves for the transmission of energy or information.
  • insulating materials usually different plastics are used, which surround the conductors used as conductors and isolate from each other.
  • Electrical conductors are usually made of copper, more rarely of aluminum or suitable metal alloys.
  • the cable follows a mostly cylindrical or similar geometry and, in its overall construction, can contain further sheath layers of insulating material or metallic foils, or braids for the purpose of electromagnetic shielding or as mechanical protection.
  • a stranded wire in electrical engineering is an electrical conductor consisting of thin individual wires. Strands are often easy to bend. In electrical cables this often copper is used as a conductor.
  • the individual wires of the stranded wire (for example, several hundred individual wires) are usually enclosed by a common insulating sleeve.
  • a conductor formed in this way is commonly referred to as a stranded conductor or stranded conductor. If several such lines are combined in one cable, they are often referred to as wires of the cable.
  • high-frequency strands (including high-frequency strands) whose individual conductor surfaces are insulated from the other stranded wires have one higher quality in the high frequency range. This is due to the increase in the effective cross-section of the current flow, which is limited in the solid wire by the aforementioned skin effect and also by the so-called proximity effect.
  • the proximity effect is based on the current displacement between two closely spaced conductors. In normal strands, ie no high-frequency strands with insulated strands, the conductors have contact with each other and the skin effect acts as with solid conductors / solid conductors. In addition, an additional contact resistance can be found by the longitudinal propagation of the current and the strand running away underneath. Therefore, normal high frequency (HF) strands tend to be worse than solid conductors.
  • HF normal high frequency
  • high-frequency strands (usually abbreviated as RF strands) provide insulation between the strands.
  • RF strands usually abbreviated as RF strands
  • paint is used for the insulation, i. the individual wires of a strand are insulated from each other by a lacquer layer. This insulation is therefore also provided if the strands lead the same potential.
  • a cable which comprises a plurality of conductors.
  • the conductors of the plurality of conductors form several conductor groups.
  • two or more of the plurality of conductors are stranded with each other.
  • the several ladder groups are completely stranded around a common stranding center.
  • the conductors of at least two of the plurality of conductor groups are stranded together with a different lay length.
  • the conductors can also be referred to as electrical conductors.
  • the plurality of conductors may be formed as a plurality of strands or as a plurality of solid conductors.
  • the plurality of conductors may include multiple strands and / or multiple solid conductors (multiple solid conductors). So a combination of strands and solid conductors is conceivable.
  • conductor groups each having two or more conductors, e.g. Litz groups each formed with two or more strands and / or solid conductor groups each formed with two or more solid conductors.
  • the conductors e.g. Strands and / or solid conductors, a conductor group, e.g. Strand group and / or solid conductor group, are stranded with each other.
  • the lay length of the stranding is different.
  • the conductor groups, e.g. Strand groups and / or solid conductor groups are stranded overall around the common stranding center.
  • Stranding (also often referred to as twisting) is understood to mean the mutual disappearance and the helical winding of fibers or wires.
  • twisting is understood to mean the mutual disappearance and the helical winding of fibers or wires.
  • the individual conductors of a circuit exchange their place in their course.
  • individual wires or wire bundles are twisted against each other. They are helically wrapped around a stranding axis / around a stranding center.
  • the stranding / twisting is an effective measure for reducing inductive coupled differential mode noise.
  • the stranding is used to reduce cross talk coupling.
  • the essential measure in the stranding is the lay length, which is often referred to as the twist length or twist step.
  • the lay length is the pitch of the helix wound around the stranding axis wire or wire bundle.
  • the stranding factor indicates the ratio of the single core length to the cable length. With reference to the described cable, this means that the stranding factor is the ratio of the actual or mechanical length of a conductor group, e.g. Strand group and / or solid conductor group to which cable length indicates.
  • the conductors of a conductor group e.g.
  • the stranding factor also gives the ratio of the length of the conductors of a conductor group, e.g. the strands of a strand group and / or the solid conductors of a solid conductor group, to the cable length.
  • the conductors for example the two or more strand groups and / or solid conductor groups, the conductors, eg Strands and / or solid conductors, the two or more in the lay length differing conductor groups, eg strand groups and / or solid conductor groups, a different length in terms of their mechanical length.
  • the mechanical length is understood here to be the actual length of the corresponding elements in their own longitudinal direction. The mechanical length can therefore be understood to mean the length of the corresponding elements in a untwisted / unwound state.
  • the electrical resistance of a wire is proportional to its mechanical / actual length.
  • the length of the conductors, eg strands and / or solid conductors, as well as the conductor groups, eg strand groups and / or solid conductor groups, can be changed and adjusted by changing the lay length.
  • the at least two of the plurality of conductor groups, eg strand groups and / or solid conductor groups, can be formed by using a certain lay length such that they have the same stranding factor, ie the same length in relation to the cable length.
  • all of the plurality of conductor groups, eg, stranded groups and / or solid conductor groups may be formed in such a way, for example by selecting suitable lay lengths, that they have the same stranding factor.
  • the two or more conductor groups e.g. Stranded groups and / or solid conductor groups, designed to have the same stranding factor, have the effect of having the conductors in their associated conductors, e.g. Strands and / or solid conductors, guided currents at least almost simultaneously with each other reach the end of the cable. That is, in the corresponding conductors, e.g. Strands and / or solid conductors, guided currents can reach the end of the cable after an equally long running time. As a result, potential differences between the elements of the conductor are minimized, ideally even eliminated. As a result, the occurrence of short circuits that lead to increased energy consumption or increased self-heating is at least reduced or ideally prevented. Such short circuits are, for example, short current pulses with partly high harmonics. Thus, by reducing or avoiding the short circuits, the electromagnetic compatibility (emV) of the cable is increased, i. emV radiation minimized or avoided.
  • emV electromagnetic compatibility
  • the at least two of the plurality of conductor groups can be arranged in the radial direction of the cable at different positions in the cable.
  • conductor groups, eg strand groups and / or solid conductor groups, which are arranged further outward in the radial direction of the cable are, a greater length than ladder groups, eg strand groups and / or solid conductor groups, which are arranged further in the radial direction of the cable inside.
  • the different mechanical length of the conductor groups for example stranded groups and / or solid conductor groups, and consequently (for the same material) the different electrical resistance of the conductor groups, eg strand groups and / or solid conductor groups, result in the same propagation velocity in the conductor groups, eg strand groups and / or solid conductor groups , guided signals, for example, currents at different maturities and thus a time-delayed reception at the end of the line. This can, as described, lead to short circuits and thus to increased energy consumption, increased warming and / or increased emV radiation.
  • the at least two of the plurality of conductor groups eg, strand groups and / or solid conductor groups, which are arranged at a different position in the cable in the radial direction of the cable, are designed such that they have a different lay length, the difference in length occurring through the overall stranding and thus (For the same material) the different electrical resistance by the different, used in the corresponding conductor groups, eg strand groups and / or solid conductor groups, stroke length can be compensated.
  • the lay length of the at least two of the plurality of conductor groups may be adjusted in the radial direction according to their position in the cable.
  • the lay length of all of the plurality of conductor groups may be adjusted in the radial direction according to their position in the cable. It is conceivable, for example, for a first of the several conductor groups, eg, stranded groups and / or solid conductor groups, to be arranged further outward in the radial direction of the cable than a second of the several conductor groups, eg, strand groups and / or solid conductor groups.
  • the further outward in the radial direction of the cable lying conductor group, eg strand group and / or solid conductor group (the first conductor group) has due to the total stranding a greater length than the further inside lying in the radial direction of the cable conductor group, eg strand group and / or solid conductor group (the second Head of group). Accordingly, the lay length of the first of the plurality of conductor groups, eg, strand groups and / or solid conductor groups, can be made larger than the lay length of the second of the plurality of conductor groups, eg, strand groups and / or solid conductor groups.
  • the lay lengths of the first and second of the plurality of conductor groups, eg, stranded groups and / or solid conductor groups may be selected so that the conductor groups, eg, stranded groups and / or solid conductor groups, are at least nearly the same length in the cable.
  • both conductor groups eg stranded groups and / or solid conductor groups
  • the lay lengths of all conductor groups may be selected so that the conductor groups, eg, stranded groups and / or solid conductor groups, have at least nearly the same length in the cable. All conductor groups, eg stranded groups and / or solid conductor groups, then achieve at least almost the same stranding factor.
  • One or more of the conductor groups are, for example, as pairs of conductors, e.g. Strand pairs and / or solid conductor pairs, formed.
  • pairs of conductors e.g. Litz pairs and / or solid conductor pairs are each two of the plurality of conductors, e.g. two of the plurality of strands and / or two of the plurality of solid conductors, stranded together.
  • the conductor groups e.g. the strand groups and / or solid conductor groups may alternatively be triple or quad strands in which three or four of the plurality of conductors, e.g.
  • the plurality of strands and / or the plurality of solid conductors are stranded together.
  • Conductor pairs e.g., stranded and / or solid conductor pairs
  • tri-and quad-strands can be combined with one another in the cable.
  • the at least two of the plurality of conductor groups may each comprise a conductor, e.g. one strand and / or one solid conductor each, as a lead and a conductor, e.g. a stranded wire and / or a solid conductor, as a return conductor.
  • a conductor e.g. one strand and / or one solid conductor each
  • a conductor e.g. a stranded wire and / or a solid conductor

  • the pitch is usually referred to as the pitch or pitch of the helix that results in the stranding of the conductors, eg, the strands or wires or solid conductors, in general.
  • the twist is also called the impact angle.
  • the impact angle ⁇ is, so to speak, the angle at which the Wire axis, the conductor axis, eg the stranded axis or solid conductor axis, cuts in elevation.
  • a larger / smaller impact angle does not necessarily result in a larger / smaller lay length. For example, despite greater impact angle, the lay length remains unchanged as the thickness of the cable is increased.
  • the cable can be designed as a power cable.
  • the cable may be used to conduct currents of at least 10A, for example between 40A and 100A, e.g. 70A, be formed at an AC frequency between 8kHz and 200kHz, for example, 85kHz.
  • the cable described below can be designed as a power cable.
  • the cable for conducting currents from 10A for example, between 40A and 100A, eg 70A, at an alternating current frequency between 8 kHz and 200 kHz, for example 85 kHz.
  • the cable can be used for various applications. That is, there are various applications of the cable conceivable. These applications may be any application in which high currents and / or high frequencies (e.g., high frequency range) are used. It is conceivable, but not limited to, that the cable is used in connection with a device for inductively charging vehicles, e.g. pure electric vehicles.
  • a device for inductively charging vehicles e.g. pure electric vehicles.
  • One way of inductively charging vehicles is to have a charging station, e.g. a wall charging station is connected to a charging device such as a charging plate via a cable / charging cable.
  • the charging arrangement e.g. the pallet, may be located at the bottom and comprise one or more coils.
  • the wall charging station is thus not connected directly to the vehicle for charging but with the charging arrangement.

  • outer elements 6a to 6f (outer elements 6a to 6f) describe a helix / helical shape, they lay in Longitudinal direction of the cable 2 a greater way back, ie, their mechanical length is greater than that of the inner element 4 (inner element 4). Therefore, an alternating signal, such as an AC / AC signal, reaches the end of the cable 2 more quickly via the inner member 4 than via the outer members 6a through 6f.
  • a part of the cable 2 already has another potential, namely the inner element 4, than other parts of the cable 2, namely the outer elements 6a to 6f. In this period, a short circuit can occur within the cable 2, which consumes energy and also leads to increased self-heating of the cable 2.

  • the mechanical length of the inner element 4 should correspond at least almost, ideally exactly, to the mechanical length of the outer elements 6a to 6h by the artificial adaptation. Due to the at least nearly identical mechanical length, an alternating signal at the same time reaches the end of the cable. Run-time differences are compensated / prevented.
