Definitions
- the "pipe” mentioned above is a physical model to understand. Indeed, in practice Solid profiles and wires are used, the inner core of which Power transmission hardly contributes. The core of the leader Basically only brings dead weight and is not physically / technically for power transmission efficient.
- the invention is based on the knowledge that the PCB technology for the development of Slideways and pantographs appear suitable. Consequently, the innovative essence of the invention is several thin metal foils in sandwich arrangement mechanically stable to fix and electrically connect.
- the uniform and safe electrical Through-contacting the metal foils with each other and to a connection contact can e.g. thereby realized be that a hole perpendicular through the foil package drilled and the wall of the resulting hole is copper-plated.
- the holes used must be used because of the homogeneous power distribution with very small Diameters are introduced.
- the length of the hole depends on the number of metal foils relatively large. The ratio diameter / length is approximately 1: 8 to 1:10.
- a slip ring transmitter consists of a rotating and a standing part consists of the principle of action to guarantee both parts are designed the same.
- the counterpart to the grinding track comes the attachment of the contact elements.
- care to wear that of the flowing in the metal foils Current can be concentrated in these contact elements must, with an acceptable level of efficiency To ensure power transmission.
- a well-known slip ring transformer for 150 A at 600 VAC 50 Hz currently fits in a hat box.
- the same Slip ring transformer with a current of 150 A and 16 kHz is about the size of a truck wheel.
- the invention is now the 16 kHz slip ring transformer from truck wheel size to hat box size. Around To achieve this goal, the above described new technological measures carried out.
- FIG. 1 a physical model shown tube 1 in Longitudinal direction in several segment strips 2 cut open, in the embodiment six Segment strips 2. These are then one above the other stacked ( Figure 2).
- the illustrated connection contact can e.g. thereby be realized that a hole is perpendicular through the Foil package 6 drilled and the wall of the resulting Lochs is copper-plated.
- the holes used must here because of the homogeneous current distribution in very small diameters can be introduced.
- the length of the Bore, depending on the number of metal foils 4, is relatively large.
- the ratio diameter / length is about 1: 8 to 1:10.
- the whole system can be electromagnetic outside be made compatible.
- the insulating layers 5 are by a Glass hard tissue formed, which at the same time the stability both the rotating parts 9 and the standing Part 10 guaranteed.
- the axis of rotation of the slip ring transmitter 8 is with Designated 12.
- the standing part 10 is on the radially outer circumference provided a guide ring 13.
- the guide ring 13 is via only schematically through center lines 14 illustrated screws with the standing part 10th connected.
- a guide groove 15 formed, in which the radially outer peripheral region 16 of the rotating part 9 engages in a sliding manner.
