Definitions
- the invention relates to a high power pivoting current supply.
- the invention relates more precisely to a current supply making it possible to transmit electrical power between two electrical machines having a relative rotational movement limited one with respect to
- This kind of current feed can for example be used between a transformer or a fixed converter and an electric motor arranged in a nacelle having a rotational movement relative to the transformer or the fixed converter.
- the nacelle is pivotally mounted under the hull. It is therefore necessary to provide a pivoting current supply between the power electronics elements on board the hull and the motor pivoting with the nacelle. It is known to produce this type of supply by connections with rotating contact rings / brushes.
- the invention relates to a current supply for conveying high current under high voltage between a first electrical appliance and a second electrical appliance mobile in rotation limited relative to each other about an axis of rotation defining a perpendicular displacement plane.
- the current supply comprises at least one flexible electrical connection having two electrical connection ends, electrically connected respectively to a first electrical connection area, and to a second electrical connection area, and stiffening elements. and holding, insulating, integral with electrical devices, to stiffen and maintain the first and second electrical connection pads in planes passing through the axis of rotation and perpendicular to the plane of movement.
- the supply comprises at least one flexible connection in the form of a conductive multi-strand braid, each connection end comprising a conductive metal plate, electrically and mechanically secured to the electrical connection pad associated therewith.
- the supply comprises at least one flexible connection in the form of a conductive foil comprising a plurality of strips stacked in a direction belonging to the displacement plane, each strip having a length such that in the extreme position of relative rotation of electrical devices, the slats are substantially parallel to each other.
- the supply comprises at least one flexible connection in the form of a conductive foil comprising a plurality of stacked strips in a direction belonging to the plane of movement, the plurality of lamellae having, in the zero position of relative rotation of electrical appliances, a sinusoidal shape in the plane of movement.
- the connection ends are formed by the associated ends of the strips, welded together.
- connection ends are formed by the associated ends of the strips, riveted together.
- the invention also relates to an arrangement of electrical machines comprising a first electrical device and a second electrical device mobile in limited rotation with respect to each other about an axis of rotation and at least one current supply between the two apparatus according to the invention, the arrangement comprises a current supply as described above.
- FIG. 1 is a general schematic representation of a device according to the invention.
- FIGS. 2A and 2B are diagrammatic representations respectively in the position without rotation and in the position with rotation of a foil according to an embodiment of the invention known as "at low angle of rotation".
- Figure 3 is a schematic representation in position without rotation of a foil according to another embodiment of the invention called "large angle of rotation”.
- the invention relates to a current supply 1 for conveying high current under high voltage between a first electrical appliance 2 and a second electrical appliance 3 mobile in rotation limited one relative to the other around an axis of rotation 4 defining a plane of perpendicular movement D.
- the current supply 1 comprises at least one flexible electrical connection 6 having two electrical connection ends 7, electrically connected respectively to a first electrical connection pad 8, and to a second electrical connection pad 9. These pads electrical connection 8, 9 are themselves electrically connected to the terminals or power bars 15 of the machine with which they are associated.
- the invention proposes stiffening and holding elements 10, insulating and integral with electrical devices 2, 3.
- stiffening and holding elements 10 isolate the different feeds from one another and relative to the metal parts of electrical devices 2, 3, they also have the purpose of stiffening and maintaining the first and second tracks electrical connection 8, 9 in planes E, F passing through the axis of rotation 4 and perpendicular to the displacement plane D.
- the invention proposes various, non-limiting, possibilities for the connections flexible electrics 6.
- At least one flexible connection comprises a conductive multi-strand braid, each connection end comprising an electrically conductive metal plate and mechanically secured to the associated electrical connection range.
- the flexible connection 6 comprises a conductive foil 11 comprising a plurality of strips stacked 12 in a direction belonging to the displacement plane D.
- Each strip 12 has a length such that in extreme position of relative rotation of the electrical devices 2, 3 ( Figure 2B), the slats 12 are substantially parallel to each other.
- This type of foil can be advantageously used for so-called "weak" rotations, that is to say between 0 and 180 °.
- the flexible connection comprises a conductive foil 13 comprising a plurality of lamellae stacked in a direction belonging to the plane of movement, the plurality of lamella having in the zero position of relative rotation of the electrical devices 2, 3 a sinusoidal shape in the plane of movement D.
- connection ends are formed by the associated ends of the strips welded together and / or riveted together.
- the connection ends 7 can also constitute the electrical connection pads 8, 9.
- the invention also relates to an arrangement of electrical machines comprising a first electrical appliance and a second electrical appliance mobile in limited rotation one with respect to the other about an axis of rotation and at least one current supply described above.
- the invention is not limited to the embodiments described, but it is susceptible of numerous variants accessible to those skilled in the art without departing from the invention.
- the number of flexible connections per feed, the different types of flexible connections of the same feed, etc. may vary without departing from the scope of the invention.
- the general shape, the preforming, and the materials of the foils and the braids can be varied without departing from the scope of the invention.
