Definitions
- the "pipe” mentioned above is to be understood as a physical model. In fact, solid profiles and wires are used in practice, their inner core hardly contributes to power transmission. The core of the leader Basically only brings dead weight and is physically / technically Power transmission is not efficient.
- DE 25 29 519 discloses an air-cooled slip ring, which consists of individual assembles annular disks spaced from each other, in which passages aligned with one another are contained, the axial form extending cooling channels starting from at least one end face.
- the circular washers consist of two or more ring sectors, that partially overlap at their edges. By these overlaps are stiffened by the slip ring. It also results by overlapping the edge parts of the ring sectors a shift of the Contact points between the brush and slip ring in the axial direction and thus an equalization of brush wear.
- a slip ring is also disclosed in the scope of US 3,871,727 which in a larger number of holes a variety of steel wires are embedded, which with their free ends to the outer surface of the Slip rings are guided.
- the holes are in disks, in particular made of an aluminum alloy. These disks are in a plastic, especially polyurethane, and are embedded by screwing with the two-part shaft of the slip ring connected.
- the invention is based on the knowledge that printed circuit board technology for the development of slideways and pantographs also at Slip ring transformers appear suitable. Hence the innovative core the invention in mechanically sandwiching several thin metal foils stable fixation and electrical connection.
- a "pipe” can be described in the physical model in the longitudinal direction cut into several segment strips, so to speak, and these are then stacked on top of each other. Located between the segment strips each have an insulating layer.
- the uniform and safe electrical through-plating of the metal foils with each other and to a connection contact is realized that a hole is drilled vertically through the foil package and the Wall of the hole is copper-plated.
- the holes used must be used because of the homogeneous power distribution with very small diameters become.
- the length of the hole, depending on the number of Metal foils, is relatively large.
- the ratio diameter / length is approx. 1: 8 to 1:10.
- a slip ring transmitter consists of a rotating and a standing In order to guarantee the principle of operation, both parts are the same designed. The comes with the rotating counter-rotating partner of the grinding track Attachment of the contact elements. Care must be taken here that the current flowing in the metal foils in these contact elements must be concentrated in order to achieve an acceptable level of efficiency To ensure power transmission.
- a known slip ring transformer for 150 A at 600 VAC 50 Hz currently fits in a hat box.
- the same slip ring transformer for one current of 150 A and 16 kHz is about the size of a truck wheel.
- the invention is now the 16 kHz slip ring transmitter of truck wheel size to bring to hat box size. To achieve this goal, the new technological measures described above.
- a becomes a physical model shown tube 1 cut in the longitudinal direction into several segment strips 2, in the exemplary embodiment six segment strips 2. These are then stacked one on top of the other ( Figure 2).
- Diameters are introduced.
- the length of the hole, depending on the number of metal foils 4 is relatively large.
- the relationship Diameter / length is approx. 1: 8 to 1:10.
- the insulating layers 5 are formed by a hard glass fabric, which at the same time the stability of both the rotating parts 9 and the standing part 10 guaranteed.
- the axis of rotation of the slip ring transmitter 8 is designated by 12.
- the standing part 10 is on the radially outer circumference with a guide ring 13 provided.
- the guide ring 13 is only schematically through center lines 14 illustrated screws connected to the standing part 10.
- a guide groove 15 is formed in the guide ring 13, into which the radially outer circumferential region 16 of the rotating part 9 slidably intervenes.
