Definitions

  • Switch arrangement for a ground transport system supplied with electrical energy by induction
  • the invention relates to a switch arrangement for a ground transport system which is supplied with electrical energy by inductive means according to the preamble of claim 1.
  • Ground transport systems which are supplied with electrical energy by induction are known.
  • a primary conductor arrangement is provided for contactless energy transmission by induction, which is supplied with alternating current of higher frequency (a few kilohertz).
  • the current conductors of the primary conductor arrangement are laid in the floor, as described for example in DE 100 37 362 Cl.
  • a ground transport vehicle can be moved along the primary conductor arrangement.
  • the ground transport vehicle is equipped with a current collector which has at least one coil as a secondary conductor and control electronics.
  • the primary conductor arrangement comprises a forward and a return line, which are laid at a constant distance from one another along a distance in the ground.
  • the route of the primary conductor arrangement can have straight areas and curves as well as branches in the form of switches. Such a primary conductor arrangement comprising straight areas, curves and switches is described for example in DE 199 55 042 AI.
  • the inhomogeneous field distribution results from the divergence of the forward and return lines of the primary conductor arrangement in the switch area.
  • the two line strands formed by the outgoing and return lines diverge from their otherwise parallel position starting at the turnout joint.
  • In the centerpiece of the switch there is an angled cable harness, the legs of which run at an acute angle to one another at a constant distance from the respective outer, continuous cable harnesses to form the continuous or the branching path are arranged.
  • the primary conductor sections before the branch and after the branch are fed by separate circuits, ie the conductor arrangements before and after the branch are supplied by separate current sources.
  • Such a design of a switch arrangement is known from DE 199 55 042 AI. With this known switch arrangement, a lower density of the magnetic field generated by the primary conductor arrangement results in a spatial area around the switch center, compared to the average density along the straight sections of the primary conductor arrangement.

  • Figure 2 Diagram of the local dependence of the power consumption of a
  • Figure 3 Diagram of the local dependence of the power consumption
  • Ground transport vehicle which travels along the continuous or branching path through a switch arrangement according to the invention.
  • FIG. 1 shows a top view of a primary conductor arrangement for a system for inductive energy transmission in the region of a branch.
  • the junction Switching arrangement forming a continuous and a branching path is defined in the primary conductor arrangement.
  • the continuous path starts from the switch joint 11 and over the switch center 5 along the arrow 14 and the branching path runs from the switch joint 11 along the arrow 15.
  • the extensions of the center lines of the continuous path and the branching path (arrow lines 14 and 15) intersect Switch center 5.
  • the switch arrangement has two outer, continuous cable strands 1 and 2. In the area (not shown in FIG. 1) in front of the switch (ie to the right of the switch joint 11 in FIG. 1), these two line strands 1 and 2 merge into the forward and return lines of the primary conductor arrangement, which are laid at a constant distance from one another.
  • the one cable run 2 runs both before and after the switch as well as in the switch area.
  • the other continuous strand of wire 2 runs in the (in Figure 1 not shown) areas before and after the stretched Soft and nikabismesfb in the turnout area itself 'RMIG curved, for example, with a typical radius of curvature of 2m.
  • Another, angled cable harness 4 is arranged in the centerpiece 3 of the switch arrangement.
  • This wiring harness 4 comprises two legs 4a and 4b which are arranged at an acute angle to one another and which merge into one another at the tip 10.
  • the wiring harness 4 is laid in this area in an approximately semicircular curve.
  • One leg 4b of the wiring harness 4 is laid in such a way that it runs in the turnout area and after the turnout at a constant distance W1 from the one continuous wiring harness 1.
  • the other leg 4a of the wiring harness 4 is laid in such a way that it runs at a constant distance W1 from the other continuous wiring harness 2.
  • the cable strands 1, 2 and 4 are each designed as stranded conductors and laid in the floor.
  • the power supply of the wiring harnesses 1, 2 and 4 takes place as described for example in DE 199 55 042 AI.
  • the two outer, continuous line strands 1 and 2 are each laid in the form of a line loop 6, 7. As shown in Figure 1, extend the two line loops 6 and 7 along the continuous line strands 1 and 2 in a partial area of the switch arrangement, which is approximately on one side through the switch joint 11 and on the other side through the points 12 and 13 on the respective continuous line 1 and 2 is defined, which is opposite the tip 10 of the angled wiring harness 4.
  • the laying of the two outer, continuous line strands 1, 2 in the form of a line loop 6, 7 has the effect that in the area along these two line strands 1, 2 in which the two line loops 6 and 7 extend, two or more line sections of consecutive turns of the line loops 6, 7 are close together.
  • line 1 as shown in FIG. 1, the two line sections 6a and 6b of two successive turns of the line loop 6 lie closely next to one another.
  • the two line sections 7a and 7b of two successive turns of the line loop 7 lie closely next to one another in the line strand 2.
  • the line loops 6 and 7 can each - as shown in FIG. 1 - be designed as loops with about 1 V 2 -turn, but they can also have more turns.
  • the number of turns of the line loops 6 and 7 and their expansion along their longitudinal axes 8 and 9 essentially depends on the geometry of the soft arrangement.
  • the number of turns and the size of the line loops 6 and 7 are preferably chosen so that the most homogeneous magnetic field possible is achieved both along the continuous and along the branching path of the switch. This can preferably be achieved in that the line loops 6 and 7 extend along the continuous line strands 1 and 2 approximately in the area in which the respective line strand 1 or 2 has a corresponding line strand 2 or 1 or 4 at a distance W2 opposite, which is greater than the distance Wl between the two outer, continuous wiring harnesses 1 and 2 at the switch joint 11.
  • the distance Wl corresponds to the distance of the forward and return line in the area of a straight section or a curve of the primary conductor arrangement.
  • the section of the switch arrangement in which corresponding sections of the line ranks 1, 2 and 4 are at a distance of W2> Wl is designated by L.
  • the length of this distance L corresponds approximately to the distance between the switch joint 11 and the tip 10 of the angled wiring harness 4.
  • the line loops 6 and 7 can - as shown in Figure 1 - with respect to the outer, continuous line strands 1 and 2 viewed from the switch center 5 respectively be directed outside. However, both line loops 6 and 7 can also be directed inwards towards the switch center 5. In an alternative embodiment, one of the two line loops 6 or 7 can also be directed inwards and the other line loop 7 or 6 can be directed outwards. Which of these variants is preferred depends on the geometry of the switch arrangement and on the space available for forming the switch arrangement.
  • the shape of the line loops is preferably approximately oval, as shown in FIG. 1, or elliptical. It has been shown that the best results with regard to a homogeneous magnetic path along the switch arrangement are achieved if the ratio of the extension of the conductor loops along their longitudinal axis 8, 9 to the extension along their transverse axis is approximately between 3 and 6 and if the ratio of the extension the cable loops along their longitudinal axis 8, 9 to the distance L between the tip 10 of the angled cable harness 4 and the switch joint 11 is between 0.4 and 1.
  • the laying of the two outer, continuous line strands 1 and 2 in the form of line loops 6 and 7 causes an increase in the magnetic field density in the area of the switch arrangement in which the line loops 6 and 7 extend along the continuous line strands 1 and 2 spatial area around the switch center 5 can be achieved.
  • the amplification of the magnetic field density in this central area of the switch arrangement depends on the geometry and the number of turns of the line loops 6 and 7.
  • FIGS. 2 and 3 the magnetic field profile in the switch area is compared on the one hand with a switch according to the prior art and on the other hand with a switch arrangement according to the invention.
  • the diagrams in FIGS. 2 and 3 each show the electrical power consumed by a current collector arrangement of a ground transport vehicle when passing through the switch arrangement along the continuous or along the branching path.
  • the electrical power consumed by the current collector arrangement is plotted in FIGS. 2 and 3 each along the route through the switch arrangement, the zero point of the route lying at the switch joint 11. It can be seen from FIG. 2 that the power consumed decreases continuously from the normalized value 1 to approximately 0.5 (branching path) or 0.7 (continuous path) when passing through the switch arrangement.
  • the width of the conduction loops 6 and 7 i.e. their extension perpendicular to the longitudinal axes 8 and 9, respectively
  • the width of the conduction loops 6 and 7 is not chosen too small, since otherwise an extinction of the magnetic flux of two is close the result would be sections of the line loops 6 and 7 lying next to one another and through which current flows in opposite directions.
