Definitions

  • the invention relates to a primary conductor arrangement for a system for inductive transmission of electrical energy according to the preamble of claim 1.
  • Conductor arrangements for contactless inductive energy transmission in which a primary circuit is formed by two parallel lines running at a distance from one another, is known from the prior art, for example from DE 197 46 919 AI.
  • a movable consumer for example a ground transport vehicle, can be moved along such a primary conductor arrangement and has a secondary circuit for inductively absorbing electrical energy from the magnetic field generated by the current-carrying primary circuit.
  • the known primary conductor arrangements are formed by a conductor loop laid along a route, which is connected to a power source.
  • the conductor loop thus comprises an outgoing line and a return line, which are laid parallel and at a predetermined distance from one another.
  • the primary circuit thus formed can be supplied with current by the current source, the current flow in the outgoing line and the return line running in the opposite direction.
  • a sufficient energy density of the magnetic field generated by the primary circuit along the conductor arrangement can only be achieved with conventional current sources in the case of conductor arrangements with a limited range, ie. H. limited length of the forward and return line can be achieved.
  • any length of the conductor arrangement is required in principle in order to enable a corresponding range of the ground transport vehicle.
  • a field course that is as homogeneous as possible, ie. H. the density of the magnetic field generated by the primary circuit is as homogeneous as possible.
  • the invention is based on the fact that the conductor arrangement is subdivided into a plurality of sections which adjoin one another, each section having a forward and a return line and connecting lines connecting the forward and return line, and that the sections are arranged with respect to one another in such a way that two successive sections meet overlap in an area near their connecting line.

  • Figure 5 Perspective representation of an intersection of two primary conductor arrangements according to Figure 1;
  • FIG. 6 Perspective detailed representation of a forward and return line of a section of the primary conductor arrangement from FIG. 1 with tuning capacitors interposed in the forward and return lines.
  • FIG. 1 schematically shows a primary circuit formed by a primary conductor arrangement 1 according to the invention for a system for the inductive transmission of electrical energy to a consumer which can be moved along the primary conductor arrangement 1.
  • the primary conductor arrangement 1 is divided into a plurality of adjoining sections (A-H). Each of these sections (A-H) has a forward line 2, a return line 3 and a connecting line 5 connecting the forward and return lines.
  • the forward and return lines of the respective sections (A - H) are designated in FIG. 1 with the reference numerals 2X, 3X and 5X, where X denotes the respective conductor section (A - H).
  • the forward lines 2 and return lines 3 are arranged parallel to each other in each section A - H and the connecting lines 5 form the transition between forward line 2 and return line 3.
  • parallel arrangement of the forward and return lines means that the forward line and the return line 3 run at a constant distance from each other.
  • the course can be straight, as in sections A, C, E and G, as well as bent to form a curve, as in sections, B, D, F and H.
  • the cables forming the primary conductor arrangement 1 are designed as stranded conductors ,
  • a current source 4 is provided in each section (A - H) of the primary conductor arrangement 1, through which current can be applied to the conductor loop of the respective section formed by the outgoing line 2, connecting line 5 and return line 3.
  • the outgoing line 2A is connected to a current source 4A via supply lines 8A and 9A.
  • the feed lines 8A, 9A run approximately perpendicular to the straight feed line 2A.
  • the further sections B to H are each equipped with a current source 4B, 4C, ..., 4H, which is connected either to the outgoing line 2 or to the return line 3.
  • Each section of the conductor arrangement is followed by an adjacent section as an extension of the outgoing line 2 or the return line 3 on both sides of the section, as shown in FIG.
  • section A adjoins section B to the right and section H to the left.
  • Sections adjoining one another are arranged in such a way that they overlap in an overlap area 7 near the respective connecting lines 5 in such a way that in the overlap area 7 the outgoing line 2X of one area immediately above and closely adjacent to the corresponding outgoing line 2X ⁇ 1 of the adjacent section runs.
  • FIG. 2 A detailed view of the overlap area 7 of two adjoining sections A, B is shown in FIG. 2. It can be seen from FIG. 2 that the length of the overlap region 7 in the longitudinal direction of the outgoing and return lines corresponds approximately to the length of the semicircularly curved connecting lines 5A and 5B. In the top view, the conductor arrangement therefore appears in the overlap region 7 like a circular winding.
  • the overlap area can also be made larger, for example approximately twice as long as the length of the connecting lines.
  • FIG. 3 also shows the overlap area 7 of two adjoining sections A and B, wherein in the vicinity of the overlap area 7 current feed points are provided to act on the outgoing lines 2A and 2B of the respective sections A and B.
  • current feed points are formed by supply lines 8B, 9B or 8A, 9A, which branch off from the respective feed line 2B or 2A and are connected to the current source 4.
  • the supply lines 8B, 9B and 8A, 9A run for the most part approximately perpendicular to the respective outgoing lines 2B and 2A.
  • the feed lines 8, 9 are laid close together in plastic pipes 10. As an alternative to the plastic pipe 10, the feed lines 8 and 9 can also be fastened tightly to one another by means of cable ties.
  • the vertical orientation of the feed lines 8, 9 with respect to the outgoing line 2 has the effect that there are no undesirable magnetic interference fields in the longitudinal direction of the outgoing or return line be generated.
  • the angled or curved section, which forms the transition from the feed line 8, 9 to the respective outgoing line 2 or return line 3, is as short as possible and in the smallest possible radius, as far as this is possible without kinking the cable.
  • the two feed lines 8, 9 can also be laid such that they lie one above the other in the curved region. In this way, the most homogeneous possible field distribution of the magnetic field generated by the current-carrying conductor arrangement is achieved in the vicinity of the current feed points.
  • FIG. 4 shows an embodiment in which the current feed point of a section B is arranged near the overlap region 7.
  • the feed point of the subsequent section A is further away from the overlap area 7 and is therefore no longer shown in the detailed view in FIG.
  • FIG. 5 shows an intersection of two primary conductor arrangements 1 a and 1 b.
  • the forward and return lines of two sections Bi b and B ⁇ a of the two primary conductor arrangements la and lb intersect in an intersection region 11.
  • the overlap regions 7, at which the respectively adjacent sections Ai b and Aj a of the associated primary conductor arrangements connect la or lb, are preferably at a sufficient distance from the intersection area 11.
  • a sufficient distance is understood to mean at least the electrically effective length of the secondary winding of the consumer device of the movable consumer.
  • At least one tunable capacitor 12 is provided in each section (A-H) of the primary conductor arrangement.
  • FIG. 6 shows a section of a primary conductor arrangement in a detailed view. Both in the outgoing line 2 and in the return line 3 there is a tunable capacitor 12 via branch lines 13, 14; 15, 16 interposed.
  • the branch lines 13, 14 of the outgoing line 2 are offset with respect to one another with respect to the branch lines 15, 16 of the return line 3 along the primary conductor arrangement, the distance being at least the same size or greater than the electrically effective extension of the consumer device of the movable consumer.
