Definitions

  • the invention relates to an electrical switchgear device multipole, and in particular to a multipole breaking apparatus comprising vacuum ampoules.
  • the document EP 0 346 603 discloses a three-pole switchgear with three identical polar break modules arranged side by side on a chassis. Each module comprises a vacuum bulb provided with a movable control rod in translation.
  • a spring drive mechanism of known type having a pole shaft allows the driving of the control rods of the three vacuum bulbs.
  • Each control rod is connected to the pole shaft via an independent linkage, specific to the corresponding cut-off module.
  • This linkage consists of a transmission lever, arranged between two connecting rods, one of the connecting rods connecting the lever to a crank of the pole shaft and the other connecting the lever to the control rod of the bulb to empty.
  • the vacuum bulbs of the different poles may be subjected to different forces during opening and closing.
  • the apparatus does not allow to easily vary the spacing between the vacuum bulbs of the different poles. It is true that the construction of identical and independent clipping modules theoretically allows any arbitrary provision. However, at each distance between poles corresponds to a different pole shaft, since the cranks of the pole shaft must be spaced the same distance from each other as the bulbs. However, the pole shaft is a particularly expensive part, especially since its torsional rigidity is critical. In addition, the need to provide shafts of different poles for each center distance prohibits to design the mechanism as a functional unit pre-assembled at the factory independently of the cutoff modules. The architecture does not favor the delayed differentiation of the different models of a range of switchgear.
  • An object of the invention is to provide a multipole electrical switchgear with independent pole modules, allowing simultaneous operation of the various modules. Another objective is to increase the modularity of a multipolar switchgear with independent pole break modules, allowing low cost to change the distance between poles. Another objective is to obtain an architecture that allows storage of standardized functional subsystems, and their assembly at the last moment to meet the needs of the customer.
  • the movable rod is, in each module, connected to the connecting rod via a pivoting connection about a fifth geometric axis parallel to the first geometric axis.
  • This provides a simple and advantageous geometric arrangement, which provides a geometric return to a pole shaft located at the height of the vacuum bulbs, while allowing the connecting rod to work in tension when closing the contacts.
  • the movable rod is connected to the connecting rod via a pivoting connection about a fifth geometric axis, this in each module.
  • the leverage effect in this configuration reduces the amplitude of the transmitted motion and a reduction of the forces, which is particularly favorable when the contacts have only a small opening and closing stroke, as it This is particularly the case for vacuum bulbs.
  • the connecting rod is arranged so as to be stressed during closing. Closing is the sequence of movement where the forces transmitted by the connecting rod are the most important. By making work the linkage in traction in this sequence, one limits the deformations of the connecting rod. When opening, the rod is biased in compression but the forces are relatively less important, so that the risk of deformation of the connecting rod out of its plan by buckling are discarded.
  • the connecting rod comprises a metal plate shaped such that its quadratic moment with respect to an axis perpendicular to a plane containing the third and fourth axes, is high.
  • the rigidity of the connecting rod to bending in a plane containing the third and fourth axes avoids any risk of delay in opening or closing one of the pairs of contacts.
  • the connecting rod comprises a sheet having two arms Vee each vee arm having a converging end supporting a bearing with one of the cranks of the pole shaft, and a diverging end, the diverging ends of the two vee arms being connected to one another by a base supporting articulation bearings with the levers of the modules cut.
  • the connecting means of the transmission lever to said rod comprise an insulating arm. This arrangement ensures isolation between the contacts and the mechanism, which is accessible to operators.
  • each breaking module comprises a frame provided with support bearings for pivoting the transmission lever around the second pivot axis.
  • the cutoff modules can then be pre-assembled and tested at the factory, before assembly with the mechanism and the connecting rod. This helps to improve the delayed differentiation.
  • the rod makes with the transmission levers an angle close to a right angle, and the rod works in translation in a plane substantially parallel to the connecting rod.
  • the geometrical plane defined by the second and fourth geometrical axes on the one hand and the geometric plane defined by the third and fourth geometrical axes on the other hand make an angle close to 90 ° between them, whereas the rod is parallel to the plane containing the third and fourth axes.
  • each breaking module comprises a vacuum interrupter constituting an enclosure in which the separable contacts are located.
  • each breaking module comprises a vacuum interrupter constituting an enclosure in which the separable contacts are located.
  • it is possibly adaptable to other breaking principles, as long as the opening and closing stroke of the contacts is low.
  • a tripolar switchgear 10 is composed of a drive mechanism 12 and three identical cutoff modules 14, 16, 18, arranged side by side on the same side of a partition 20 separating them from the drive mechanism. 12.

  • the pole shaft 32 comprises two double cranks 36, 38 which pass through the wall of the chassis through slots and allow the articulation between the shaft of the poles 32 and a transmission rod 40.
  • the transmission rod 40 is constituted by a flat part forming two double vee arms 42, 44, spaced from one another, and connected on the diverging end side by a base 46.
  • Each vee arm 42, 44 supports, at its convergent end, a pair of lugs 50, 52 provided with coaxial bores, forming bearings.
  • the cranks 36, 38 also comprise coaxial bores forming bearings, so that a hinge-type pivot connection is obtained between the double cranks 36, 38 of the pole shaft 32 and the rod 40 by insertion of pins 54 into each other.
  • the base 46 supports three pairs of tabs 60, 62, 64 provided with coaxial bores, forming bearings.

  • the contact 92 is fixed and connected to the second flange 98.
  • the other contact 90 constitutes an axial end of a rod 100 movable in translation along its axis and passing through the body 88 of the bulb through a hole of the flange 96.
  • the electrical connection of the rod 100 to the busbar is ensured by means of a flexible electrical connection 104, one end of which also constitutes the connection pad 84.
  • the rod 100 is connected to the double lever 74, via an insulating arm 110.
  • the insulating arm comprises a plastic body 112 overmolding on the one hand the head of a first threaded rod 114, and secondly the head of a second threaded rod 116 located in the axial extension of the first.
  • the first threaded rod 114 is screwed into a threaded blind hole located at the end of the rod 100 of the bulb 80.
  • On the second threaded rod 116 is screwed a tubular adjusting nut 118.
  • the nut 118 supports at one end a support plate 120 for one end of a contact pressure spring 122.

  • the levers 70, 72, 74 are parallel.
  • the kinematic chain connecting the shaft of the poles 32 to the rods 100 of the three breaking modules 14, 16, 18 comprises a single connecting rod 40 connecting the pole shaft 32 and the three double levers 70, 72, 74 of the cutoff modules, and is extended in each module by an insulator 112, one end slides in a sheath 128 pivoting relative to the double lever 70, 72, 74, and the other end is integral with the rod 100 of the bulb 80.
  • This kinematic chain makes it possible to define five geometrical axes of parallel rotation: a first geometrical axis 140 of pivoting of the pole shaft, a second pivot axis 142 of the levers 70, 72, 74, a third geometric axis 144 pivoting the rod relative to the cranks of the pole shaft, a fourth geometric axis 146 of pivoting of the rod relative to the levers, and a fifth geometric axis 148 of pivoting of the bars 126 relative to the levers 70, 72, 74.

  • this clearance is absorbed by the existing gaps between the various elements of the driveline, in particular at the axes 130, 132.
  • the driveline operates in the following manner.
  • the kinematic chain is initially in the position shown in FIG. figure 2 .
  • the closing spring of the mechanism 12 drives the pole shaft 32 in the opposite direction of the clockwise, over a stroke of more than 50 °.

  • the kinematic chain is in the closed position of the figure 4 , the contacts being closed.
  • the opening spring of the mechanism 12 drives the pole shaft clockwise over a travel of more than 50 °.
  • the connecting rod 40 transmits this movement uniformly to the three double levers 70, 72, 74.

  • the single rod 40 has a high quadratic moment with respect to an axis perpendicular to the geometric plane containing the axes of pivoting of the connecting rod with respect to the pole shaft and the double levers.
  • the base 46 preserves the desired rigidity. In other words, the forces applied to the rod in its plane are not likely to induce a significant bending of the connecting rod. Therefore, the link 40 gives the kinematic chain a high rigidity, so that even if the forces to be applied to different bulbs are different, their movement will nevertheless be simultaneous.
  • the pole shaft 32 itself is very torsionally rigid, so that it is possible to space the two hinges connecting the connecting rod 40 to the pole shaft 32 which contributes to further reinforce the rigidity of the kinematic chain.
  • the connecting rod is manufactured by cutting a sheet.
  • the levers are also made of sheet metal.
  • the electrical insulation is carried out in each breaking module thanks to the insulating arms. It should be noted that the insulating portion 112 of the arm is skirted so as to provide optimum insulation.

  • the levers 70, 72, 74 may be simple.
  • the drive mechanism can be of any type: with closing springs and distinct opening, to allow a sequence closing, arming, opening, closing, opening; single spring for closing and opening.
