Definitions
- the invention relates to an electrical switchgear comprising a movable rod and a flexible electrical connection between the movable rod and a fixed connection range.
- EP 0 058 519 discloses a switchgear including the contact member mobile comprises a cylindrical rod movable in translation along its axis.
- This stem is connected to an external connection area via a flexible conductor constituted by a stack of metal strips.
- Each metal strip has a circular opening with legs protruding out of the plane of the metal band, towards the center of the opening.
- the rod is inserted in the openings of the strips, then we take the sandwich drivers between two clamping plates.
- the plates are connected to each other by bolts. When one tighten the bolts, the plates tend to compress the metal strips of the driver flexible in the region with openings, causing deformation and creep legs in contact with the rod.
- Such a connection requires a fairly long assembly time.
- it implements massive mechanical parts that must move with the stem during openings and Closures of the apparatus. It follows that the energies of opening and closing are high, and that the shocks caused at the end of the race also have a high energy.
- the entire opening and closing mechanism of the switchgear shall then be dimensioned so as to be able to provide such energies of opening and closing, and to be able to withstand the corresponding shock energies.
- the stem temperature increases when the bulb is traversed by a nominal current, until, at the level of the flexible conductor attachment, the order of 100 ° C and more. At such temperatures, the screwing does not appear as a reliable solution over time.
- the mobile equipment of a vacuum interrupter is fragile, and should not be used outside its axis of translation. Care must be taken to avoid damage the bulb when fixing the connection.
- the area adjustment in force which ensures the passage of current between the rod and the driver mobile, has a high resistivity and that it is subjected, during the passage of the current nominal temperature, to a temperature rise which tends to cause differential different elements, because of differences in the coefficients of expansion of the materials components of the stem on the one hand, and the stack of metal plates on the other. AT this dilation effect is added to the tendency of materials to flow under the influence of temperature, particularly in the force adjustment zone.
- any primer local deterioration of the junction tends to increase over time as it locally causes an increase in resistivity that causes a rise in temperature. The reliability of the binding is reduced.
- the invention therefore aims to remedy the drawbacks of the state of the art and to propose a junction zone between the movable rod of a switchgear and a link flexible electrical system, which has excellent current conduction properties, which is light, reliable in time, and simple to manufacture.
- the one-piece assembly constituted by the welded assembly of the metal blades at the level of of the first rigid end portion, ensures a good mechanical strength of all. Brazing provides a metallurgical connection between the rod and the driver flexible.
- the metal feed compound has a determined melting point, depending on the chemical elements constituting it, lower than the melting points of metal parts that it allows to bind. Indeed, the parts to join, in this case the rod and the connector flexible, must not participate by fusion in the constitution of the joint during the assembly pieces.
- the melting point of the solder is substantially less than 900 ° C, and preferably less than 700 ° C.
- the choice of a solder at a temperature of low melting must not be done to the detriment of the electrical conductivity of the brazing, nor to the detriment of its mechanical strength.
- the metal compound is a silver-based compound in proportions greater than 30%, with a tin content in proportions of less than 10%. In particular, we will prefer proportions greater than 50% in silver, with a contribution of tin in proportions less than 6%. Silver gives the solder excellent electrical conductivity.
- Tin for its part, makes it possible to lower the brazing temperature, but has the defect of rendering ductile soldering (solder), which is not desired. This is why the proportion tin must remain low.
- a quaternary compound Ag-Cu-Zn-Sn can be used.
- the compound is quaternary and contains 56% silver, 22% copper, 17% zinc and 5% tin, with a melting point of about 650 ° C.
- the solder does not contain cadmium, despite the known property of this component of lowering brazing temperatures, because of its potential harmfulness to the environment.
- the metallurgical bond obtained ensures excellent electrical conduction. She does not increase the mass of the moving equipment, so that the kinetic energy to dissipate at the end of the opening or closing run remains relatively low. Brazing once the junction is not sensitive to temperatures of the order of 100 ° C at which it is subjected during the passage of the current, so that it does not deteriorate in the time under the influence of temperature.
- the projecting portion of the rod comprises an axis, limited on the side of the ampoule by a shoulder, a part of the filler compound constituting a seal interface interposing axially between the shoulder and an axial rim of the bore, and another part of the feed compound constituting a radial interface seal between the bore and the axis.
- a junction having an excellent mechanical strength is thus obtained.
- the axis constitutes a free end of the rod, so that the assembly operation is particularly simple. It suffices to insert successively on the axis a washer of solder, then the bore of the connection, before carrying out the soldering operation.
- the axis is circular in section, and the bore, so that the seal
- the radial interface between the bore and the axis conforms to a cylindrical shape, which makes it possible to to overcome the constraints of radial positioning of the connection relative to the axis.
