Definitions
- the present invention relates to techniques for improving the electrical connection between two metallic conductors, and relates in particular to a powder and a paste for improving the conductance of the electrical connection between two metallic conductors.
- a contact device comprising an intermediate conductive element consisting of a metal foam skeleton selected from the group consisting of iron, cobalt, nickel and their alloys coated with at least one coating of tin, indium or a of their alloys.
- the two conductors 12 and 14 are separated by an intermediate conductive element 10 of metal foam so that their surfaces come into contact with the foam.
- the electrical connection between the conductors 12 and 14 is made by close contact thanks to a clamping means such as a clamping bolt 16 passing through the two conductors as well as the intermediate conductive element.
- the spacer element preferably comprises a peripheral seal 20 to reduce the penetration of degrading external agents by creating a sealed barrier at the periphery of the contact.
- the main object of the present invention is therefore to provide electrical connection means making it possible to improve the electrical conductance of an electrical connection and to slow the degradation of the surfaces in contact, in particular when the connection is made by means of a cable having a plurality of strands.
- a first object of the invention is an electrical connection powder consisting of open-cell foam particles having a size of between one and two millimeters, for example 1.6 mm, said foam consisting of a foam skeleton.
- metal selected from the group consisting of iron, cobalt, nickel and their alloys coated with at least one coating of tin, indium or an alloy thereof.
- a second object of the invention is an electrical connection paste comprising the above powder and a binder in which the powder is dispersed.
- connection according to the principles of the invention can be realized as illustrated in FIG. figure 1 .
- the connection may comprise a conductive intermediate element 10 between two conductors 12 and 14, but this intermediate element consists of the powder or paste which are the objects of the invention.
- the electrical connection between the conductors 12 and 14 is made by close contact thanks to a clamping means such as a clamping bolt 16 passing through the two conductors as well as the intermediate conductive layer 10.
- the intermediate element when the two conductors are clamped together, the intermediate element is compressed and its thickness decreases in part because grains of powder or the binder of the paste in which the powder is dispersed are ejected at the periphery of the the intermediate element. Therefore, contrary to the embodiment described in the patent published under number 2.962.856, it is unnecessary to provide a seal surrounding the intermediate element.
- At least one of the conductors is aluminum.
- the present invention is not limited to this case and applies to all conductors, for example copper.
- the metal foam is a foam-type open-cell foam composed of a metal foam skeleton selected from the group consisting of iron, cobalt, nickel and their alloys coated, for example directly, with at least one metal coating such as a coating of tin, indium or one of their alloys.
- the structure of the foam is cellular and its physical property is mainly a high porosity and deformability, which has the effect of reducing the electrical resistance of the connection, and a low density of the order of 400 g / m.
- a feature of the invention is that the metal foam skeleton is coated, for example directly, with a coating of another metal, by electrolysis or any other another method (projection, immersion in a bath ...) so that the entire alveolar surface is coated with this other metal.
- the coating metal is preferably a ductile metal such as tin, indium or one of their alloys, in order to increase the contact area of each point of the metal constituting the skeleton, of penetrate the streaks of the conductor surface and improve the electrochemical compatibility between the skeleton of foam and the metal of the driver.
- first coating may also be covered with another coating of a metal different from that of the first coating, and so on.
- first coating is tin
- second coating may be indium.
- the metal foam is then reduced to powder by any suitable means.
- the grains thus obtained preferably have a diameter of approximately between 0.5 mm and 5 mm, and preferably between one and two millimeters, for example 1.6 mm.
- the metal foam is then reduced to powder, the particles of which have a size of between 1 and 2 mm by any appropriate means making it possible to preserve the honeycomb structure.
- the powder is obtained by laser cutting, which does not alter the foam structure of the foam and keeps all the electrical and mechanical characteristics of the foam.
- laser cutting makes it possible to create sharp edges on the small pieces of foam which will thus penetrate more easily into the conductors in contact.
- the powder obtained consists mainly of vacuum because of its honeycomb structure.
- the surface of the particles of the powder comprises a multitude of micron contact points whose number reaches 30 points per mm 2 . Thanks to these points, the element interlayer 10 having many contacts, has a high conductivity and therefore a low resistance.
- the powder is dispersed in a binder so as to form a paste which, like the powder, makes it possible to improve the electrical conductance of an electrical connection.
- This binder which may be grease or petroleum jelly, completely fills the cells with the foam particles, which prevents the penetration of pollutants or agents that can oxidize or degrade the surfaces.
- this fat can incorporate anti-oxidation products and metal particles of a few microns increasing its life.
- Particles can be particles of silver, gold or any other metal that is a good conductor of electricity.
- the foam powder may also be impregnated or charged with a component to reduce the formation of a high resistivity layer on the surface of the conductors, such as alumina on a conductor. aluminum, and / or etching the surface of the conductors.
- the powder and the dough which are the subject of the invention can be used for an old electrical connection or for a new electrical connection.
- the contact is even more important that it is located near the clamping means or bolt 16. Therefore, the resistance, and therefore the electrical losses of the electrical connection consisting of the conductors 12 and 14 in contact, is minimal near the clamping means 16 and increases more away from it.
- This inhomogeneous distribution of the current favors a zone of higher current concentration and therefore an area more stressed and therefore degraded more quickly.
- the addition of the conductive powder particles or the paste of the layer 10 increases the contact points between the two conductors 12 and 14 and thus allows a homogeneous distribution of the current over the entire surface of the contact. Thanks to this homogeneous distribution, there are no areas of concentration of current and therefore no zone more solicited and conducive to a more rapid degradation.
- the powder and the dough which are the subject of the invention can also be advantageously used for a contact of a degraded or deformed electrical connection.
- This degradation is due to the oxygen in the air which causes the formation of an oxide layer.
- this oxide which is alumina, increases the resistance of the connection.
- the tips located on the surface of the particles of the powder also pierce the oxide layer such as alumina which is formed permanently on the surface of the conductors 12 and 14, which makes it possible to improve the electrical conductance of a used connection, even without cleaning it first.
- Another advantage of the paste according to the invention is to provide a coating of the strands which prevents their oxidation.
- the figure 3 represents an electrical connection using a cable.
- the end is formed of a lug 20 which is generally flat and has a hole 22 used for clamping the lug on another flat conductor. Improved contact between the pod and the other Conductor is made in the manner described above by an intermediate layer of powder or pulp objects of the invention.
- the lug 20 is connected to the cable 24 by a crimping ring 26 on which is exerted a high pressure during assembly to achieve good electrical contact between the lug 20 and the cable 24.
- the cable Before crimping the cable 24 by the ring 26, the cable is immersed in the powder which is the subject of the present invention or the strands of the cable are coated with the dough which is the subject of the present invention, for example by spraying, so that the dough enters the interstices between the strands of the cable, for example the gap 36.
- the powder or paste penetrates deeper into the interstices thanks to the pressure exerted
- the powder and the dough which are the subject of the present invention are all the more advantageous as their effectiveness increases with temperature.
- the potential drop of a 1 dm 2 connection using the powder or the paste according to the invention originating from a nickel foam covered with tin is of the order of a few mV for a current of one intensity of 5000 A and at a temperature of 80 ° C. This feature is due to the fact that the points of the foam are welded under the effect of temperature to the conductors with which they are in contact.
- the powder and the paste according to the invention are particularly advantageous for improving the conductance of the electrical connections in which the two conductors are made of aluminum, but also when one of the two conductors is made of copper and the other of aluminum or when both conductors are copper.
- the powder and the paste which is the subject of the present invention are particularly suitable for currents high intensity, for example an intensity greater than 1000 A.
- the powder and the paste which are the subject of the invention find application in all fields of electrical engineering which use currents of high intensity.
- the wear of the electrical connections which are subjected to currents of high intensity and at high temperatures is concretized mainly by a deformation of the contact surfaces of the connections. electric. This results in significant electrical losses of up to several KW per connection and variations in the intensity of the current passing through these contacting surfaces.
- powder or paste object of the invention can also be used to improve sliding contacts in heavy industries such as anode contacts used in the electrolysis of aluminum.
- the powder or the paste object of the present invention follow the contours of the degraded surfaces of the conductors in contact and thus increase the contact surface.
