Definitions

  • the present invention relates to an inductive load connected to an electrical energy store in a motor vehicle.
  • the invention relates to an electrical energy store in the form of a (rechargeable) vehicle battery which is connected to an inverter or another electronic power module which switches at high frequency, the inverter in turn feeding an AC motor which forms the inductive load.
  • cables are known in which the individual conductors (plus, minus) are formed by conductor elements arranged in a cross-section in a checkerboard pattern.
  • this arrangement is complex to manufacture and to connect.
  • the insulation of the individual conductor elements from the adjacent conductor elements is complex and causes a considerable increase in the overall cross section.
  • this arrangement is not based on the problem of the high inductance of the feed line, but rather on the lowest possible total magnetic radiation.
  • the three-phase coaxial cables described there are used to transmit high powers in the range between 100 and 1850 MVA instead of conventional cables, since the three-phase coaxial cables can transmit higher currents at the voltages in question here between 110 kV and 400 kV. Statements about the reduction in the inductance of such three-phase coaxial cables cannot be found in this article. This is due to the fact that the three-phase coaxial cables are used here only for the unidirectional transmission of energy between an energy store and a load. The use of high-frequency switching electronic power modules, in whose operation the inductance of the energy supply and discharge cables play a major role, is not described.
  • the invention is based on the problem of providing a connecting line between an electrical energy store and an inductive load in the motor vehicle connected to it via a fast-switching circuit breaker.
  • a feed line is provided between an electrical energy store and an inductive load connected to it via an electronic power module that switches at high frequency in a motor vehicle, which feed line connects a first terminating pole of the electrical energy storage connected core conductor and a surrounding this, connected to a second connection pole of the electrical energy storage sheathed conductor.
  • This arrangement has the advantage that the feed line is extremely low-inductance. Comparative measurements have shown that the inductance of a feed line according to the invention is approximately 15 times less than the inductance of a two-wire strand with a corresponding cross-sectional area. Furthermore, this arrangement allows small bending radii for the feed line in any direction, as are required for installation in motor vehicles.
  • the electrical energy store is a rechargeable battery, preferably a lead / acid accumulator, and the high-frequency switching electronic power module is an inverter.
  • the inductive load is preferably an AC motor, preferably an asynchronous motor, which is arranged in the drive train of the motor vehicle as a starter, generator (alternator) and vibration absorber.
  • the core conductor has a cylindrical cross-sectional shape and the sheathed conductor surrounding it has a corresponding cross-sectional shape with essentially the same cross-sectional area.
  • the cross-sectional shape of the core conductor and the sheathed conductor are circular.
  • the core conductor is separated from the sheathed conductor by a first insulation layer and the sheathed conductor is surrounded by a second insulation layer.
  • the sheathed conductor separated by a further insulation layer, can be surrounded by at least one further sheathed conductor.
  • the outermost sheathed conductor can be surrounded by an additional shielding sheath, preferably made of wire mesh.
  • the core conductor and / or the or each sheathed conductor are preferably formed from stranded wire strands. This ensures particularly good flexibility, even with larger cross sections.
  • the invention also relates to the feed line itself with a core conductor and the concentrically surrounding one another
  • FIG. 1 shows a schematic block diagram of a functional group according to the invention with an energy store, a feed line, an inverter and an inductive load.
  • Fig. 2 shows a partially sectioned side view of a feed line according to the invention in a first embodiment.
  • FIG. 3 shows an end view of the feed line according to the invention from FIG. 2.
  • Fig. 4 shows a partially sectioned side view of a feed line according to the invention in a second embodiment.
  • FIG. 1 shows the functional group according to the invention, which has an electronic power module 14 and an electronic power module 14 connected to the battery 10 by means of a feed line 12 with two conductors 12 inductive load 16.
  • the electronic power module 14 is only indicated schematically by two power switches 14a, 14b and two free-wheeling diodes 14c, 14d, with the control circuit for the two high-frequency switching (semiconductor) switches 14a, 14b in particular no longer being indicated Details of such an electronic power module 14 are described, for example, in the applicant's German patent specification 42 30 510 C1
  • the inductive load 16 is preferably a phase (n winding) of an asynchronous motor (not illustrated further) of the asynchronous motor sin d equally connected to the feed line 12 via corresponding electronic power modules 14.
  • the one (drawn with greater line width) conductor 12 'of the feed line 12 with a first Connection pole 10a of the electrical energy store 10 is connected and configured as a core conductor, while the second conductor 12 ′′ of the feed line 12 (drawn with a larger line width) is a sheathed conductor 12 ′′ surrounding the core conductor 12 ′ and connected to a second connection pole 10b of the electrical energy store 10.
  • the sheathed conductor 12 ′′ is preferably connected to the ground connection and the core conductor 12 * to the positive pole of the battery 10.
  • the core conductor 12 * has a cylindrical cross-sectional shape and the sheathed conductor 12 ′′ surrounding it has a corresponding cross-sectional shape with essentially the same cross-sectional area.
  • a first insulation layer 18 * made of plastic is arranged between the core conductor 12 'and the sheathed conductor 12 ".
  • the sheathed conductor 12" is also surrounded by a second insulation layer 18 "made of plastic.
  • the core conductor 12 ′ and the sheathed conductor 12 ′′ each have a circular-cylindrical or circular-cylindrical cross-sectional shape.
  • the feed line can 12 in the manner shown in Fig. 2 gradually stripped so that (not shown) connection clamps can be put on.
  • a feed line for a three-phase connection is shown.
  • the principle of concentrically surrounding conductors can also be continued with an even larger number of conductors.
  • a common ground conductor can be provided for several phase conductors, in which
  • cross-sectional area of the ground conductor should be the sum of all cross-sectional areas of the individual phase conductors.
  • a ground line can also be provided for an adjacent, internal phase conductor.
  • Both the core conductor and each of the sheathed conductors are formed from bare copper wires by stranding.
  • the outermost sheathed conductor is surrounded by an additional shielding sleeve 20 (see FIG. 3) made of wire mesh, which may be electrically insulated from the outside.
