Definitions

the present invention relates to an electrical conductor comprising a metal bar lined with a sheath made of a metal different from that of the bar.
Electrodes of this type are commonly used in the construction of electrodes intended for the electrolysis cells of aqueous solutions, in particular sodium chloride solutions.
they usually include a copper rod jacketed with a sheath made of a metal inert with respect to the chemical environment in the electrolysis cell and they are engaged horizontally or vertically between a pair of vertical metal plates forming the actual electrode.
the metal of the sheath is generally chosen from iron, nickel and their alloys.
the copper bar is used for its high electrical conductivity and therefore has the main function of conveying high current densities, while the sheath is used to isolate the copper bar from the corrosive action of the electrolytes circulating in the cell. electrolysis.
the sheath also has the additional function of ensuring the circulation of electric current between the bar and the plates of the electrode. It is therefore desirable to minimize the electrical contact resistance between the bar and the sheath. To achieve this objective, consideration has been given to using electrical conductors obtained by a metallurgical operation of co-threading the bar and the sheath. The electrical conductors obtained by this technique are however expensive.
the invention aims to remedy the aforementioned drawbacks, by providing an electrical conductor formed of a rod jacketed with a sheath, which has good electrical conductivity in the contact zone between the rod and the sheath and whose manufacture is easy and economic.
the invention relates to an electrical conductor comprising a metal bar lined with a sheath made of a metal different from that of the bar; according to the invention, the bar has at least one longitudinal groove containing a cord made of the same metal as the sheath, welded to the bar, and the sheath has an opening facing the cord, said opening containing a metallic mass welded to the cord and to the sheath .
the main function of the metal bar is to conduct the electric current.
the sheath fulfills two functions: on the one hand, it serves to isolate the bar from the chemical environment in which the electrical conductor is used; on the other hand, it serves to transfer the electric current in the transverse direction to the bar between the latter and a metallic element (for example an electrode) connected to the sheath.
the profile of the bar is not critical. It may for example consist of a cylinder of circular or oval cross section, or of an elongated parallelepiped, the cross section of which is a square, a rectangle, a trapezoid or another regular or irregular polygon. For reasons of ease of construction, it is preferable to use a straight bar of square or rectangular cross section.
the bar has a longitudinal groove. This can extend over the entire length of the bar or only a fraction thereof. The groove serves as a receptacle for a metal cord made of the same metal or alloy as the sheath, this metal cord being welded to the bar.
the sheath must have a profile that fits the profile of the bar, so that it can wrap it over approximately its entire length.
the profile of the sheath and its arrangement around the bar must also be such that the sheath has an opening opposite the metal cord located in the groove of the bar.
the opening of the sheath can be a slit which extends over its entire length or over only a part of it. It serves as a receptacle for a metallic mass made of the same metal or alloy as the sheath, this metallic mass being welded to the cord and to the sheath.
the metal of the sheath depends on the destination of the electrical conductor. It must be chosen from among those likely to be welded to the metal of the bar.
the metal bar is made of copper and the sheath is made of a metal chosen from iron, nickel, iron alloys and nickel alloys.
Iron alloys include ordinary carbon steels and alloy steels such as, for example, stainless steels alloyed with chromium, nickel and molybdenum and silicon steels which have particular electrical properties.
nickel alloys are monel (alloy of nickel, copper, iron, manganese, silicon) and inconel (alloy of nickel, manganese, iron, silicon, chromium, aluminum and titanium).
the electrical conductors according to this embodiment of the invention find a particular application in the construction of cathodes intended for the cells of electrolysis of aqueous solutions of alkali metal chloride.
the sheath is a metal sheet folded around the bar so as to wrap the latter, and the aforementioned opening is a slot delimited between the two edges juxtaposed with the sheet.
the bar has two longitudinal grooves each containing a cord made of the same metal as the sheath, and the sheath is formed by two separate longitudinal shells in the form of a gutter, which longitudinally cover the bar by providing between their longitudinal edges which face each other, a gap constituting the abovementioned opening opposite each bead.
the sheath therefore has two longitudinal openings in the form of slots, which are located opposite the cords and which contain two metallic masses as defined above, welded respectively to the two cords and to the two cockles.
the bar is coupled to the sheath by a welded assembly, consisting of the or each aforementioned cord and the or each said metal mass.
This welded assembly ensures optimum electrical connection between the bar and the sheath and consequently reduces the resistance to the passage of electric current between the bar and the sheath.
the invention also relates to a method of manufacturing an electrical conductor, by assembling a metal bar and a sheath made of a metal different from that of the bar; according to the invention, at least one longitudinal groove is formed in the bar, a bead of the same metal as the sheath is welded in the groove of the bar, the bar is engaged in the sheath, leaving an opening in the latter facing the cord and the sheath is welded to the cord in the above-mentioned opening.
the bar can for example be obtained by a steel rolling operation.
the groove can be formed in the bar during rolling, or it can be formed later by a machining operation.
the sheath can be obtained by a rolling operation of the type used for the manufacture of metal tubes, the aforementioned opening in the sheath being then obtained by machining.
a sheath obtained by bending or bending a metal sheet is used, and a gap forming between the longitudinal edges of the bent sheet is maintained. 'the aforementioned opening, intended to contain the metallic mass.
two longitudinal grooves are formed in the bar and a sheath obtained is implemented by joining two longitudinal metal shells so as to maintain a spacing between their edges arranged facing each other. screw, said spacing forming the above opening.
the two shells have the shape of a gutter and are for example obtained by stamping a metal sheet.
the electrical conductor according to the invention is specially designed for the transport of electric current longitudinally in the bar and transversely through the sheath. It is suitable for both direct and alternating current. It finds an interesting application in the construction of electrodes intended for electrolysis processes, such as iron, steel or nickel cathodes commonly used in the processes of electrolysis of water or aqueous solutions of chlorides of alkali metals.
the invention therefore also relates to an electrode for an electrolysis cell, comprising at least one plate made of a metal selected from iron, nickel, iron alloys and nickel alloys, said plate being fixed to a conforming electrical conductor.
the bar is made of copper and the sheath is made of the same metal as the plate.
This electrode finds application as a cathode for the production of hydrogen and aqueous solutions of sodium hydroxide in an electrolysis cell of aqueous solutions of sodium chloride.
the plate can be full or perforated. It may for example be a sheet of expanded metal.
Figure 1 shows, in cross section, a particular embodiment of the electrical conductor according to the invention.
FIG. 2 shows a particular embodiment of the electrode according to the invention, in section along the horizontal plane II-II of FIG. 3.
FIG. 3 is a vertical cross section along the plane III-III of FIG. 2.
the electrical conductor shown in FIG. 1 comprises a copper bar 1, in a nickel sheath 2.
the copper bar is a straight bar, of rectangular section which has been obtained by rolling. It has, on two opposite faces, two grooves 3, 3 '.
the grooves 3 and 3 ' are filled with nickel cords 4 and 4'.
the nickel beads were formed in the grooves by melt deposition, using a conventional arc welding technique using a nickel or nickel alloy welding rod, so that they are welded to bar 1.
the sheath 2 consists of two shells 5 and 6, having the shape of gutters coming exactly to marry the periphery of the bar 1.
the shells 5 and 6 were obtained by stamping two sheets of nickel. Their dimensions are chosen so that a slot is delimited between their longitudinal edges 7 and 8 facing the bead 4 and that a second slot is defined between their other longitudinal edges 7 'and 8' facing the bead 4 '. These two slots are filled respectively with two nickel masses 9 and 9 '. These are obtained by deposit at the molten state, by means of a conventional arc welding technique using a nickel or nickel alloy welding rod, so that they are welded to the beads 4, 4 ′ and to the shells 5 and 6.
the cords 4 and 4 'and the metal masses 9 and 9' provide both a mechanical attachment of the sleeve 2 to the bar 1 and an electrical connection of low resistance between the bar 1 and the sleeve 2.
the electrode shown in FIGS. 2 and 3 comprises a pair of perforated vertical plates 10, 10 ′ in nickel, arranged in parallel and facing one another, on either side of a horizontal metallic conductor designated in as a whole by the reference notation 11.
Two corrugated sheets 12, 12 'in nickel are used to connect the plates 10 and 10' to the conductor 11.
the conductor 11 conforms to that shown in Figure 1 and described above.
the fixing of the sheets 12 and 12 'to the conductor 11 is also obtained by a welding operation. This is carried out along the metallic masses 9 and 9 'of the electrical conductor, so as to minimize the electrical resistance of the junction between the plates 10, 10' and the bar 1 of the electrical conductor 11.
