  • the longitudinal displacement of the drive rod 4, along the axis AA ', is transformed into rotation of the axis 81.

  • the rotating cam 80 transmits a longitudinal displacement of the shafts 13, 23, kept in contact with the external profile of the cam 80 via the springs 14, 24 ( Figure 1A ).
  • the cam 80 with an external profile therefore generates a thrust force of the shafts 13, 23 and thus the closure of the pairs of contacts 11, 12 and 21, 22 respectively along the axis AA 'and BB'.
  • the springs 14,24 in turn, generate an opening thrust force of the pairs of contacts 11,12 and 21,22, which as opposed to that generated by the outer profile of the cam 80 is similar to a pulling force of the shafts 13, 23 still along the same axes AA 'and BB'.

  • the direct contact induces a resisting torque on the cam 80 due to friction, thereby causing a loss of energy dissipated in the form of heat in the two parts 13 or 23 and 80 in contact while the use of a roller 15 allows to increase the efficiency by reducing friction by substitution of sliding friction in rolling friction.
  • the inner profiles P1, P2 ( Figure 5A ) or the outside one P ( Figure 1A ) of the cam 80 determine the longitudinal translation movement and the lifting of the shafts 13, 23 as well as the opening time (see timing diagram in figure 6 ).

  • a complementary rotation of an angle ⁇ 1 ( figure 3C ), during which the shafts 13 and 23 both remain on a profile of the cam 80 in a circular arc centered on the axis of rotation 81, allows the circuit breaker 1 to remain in the open position and the disconnector 2 in the closed position.

  • the rotation of the cam 80 by an angle ⁇ 2 drives the shaft 23 in translation along the axis BB 'until the contacts 21, 22 of the disconnector 2 are completely closed. Then, the rotation of the cam 80 continues on an angle ⁇ 1 leaving the disconnector 2 in the closed position and the circuit breaker 1 in the open position.
  • the complementary rotation of the cam 80 according to the angle ⁇ ensures the complete closure of the circuit breaker 1.
  • a single cam 80 makes it possible to realize the laws of lifting of the shafts 13,23 and thus of the pairs of contacts 11,12 and 21,22.

  • Non-rectilinear guide grooves 960, 970 are arranged between them with their straight portions 960d, 970d parallel to each other. Due to this arrangement, the distance between the rollers 96 and 97 remains constant and the diamond 9 remains indeformable during this first phase ( Figure 7A ). In other words, the displacement of the lower vertex 9j is identical to that of the upper vertex 9i of the rhombus 9.

That said, in the construction of the guide grooves 960, 970, it is possible that the change of direction also causes a slight rebound at the end of the stroke of the order of a few mm (less than 10 mm) of the contacts 11, 12 of the circuit breaker 1, which, in any case, remains compatible with the breaking and dielectric performance of circuit breaker 1.
  • the coupling roller 98 is directly connected to the rod 23 of operating the disconnector, it therefore performs an identical race when opening and closing the disconnector 2.

  • the maneuvering forces that apply are translated at the rhombus 9 which transmits the movement, as shown in FIGS. Figures 7 to 7D , by a pressure force of the rollers 96 and 97 in the associated guide grooves 960, 970.

  • the bar 131 shown is integral with the shaft 13 and the bar 90 'is secured to the connecting rod 90. It is quite possible, in the of the invention, to have the bar 131 and the shaft 13 made in the same room. Similarly, it is quite possible to have the bar 90 'and the connecting rod 90 also made in the same room.
  • the invention makes it possible to have drive means common to a circuit breaker 1 and a disconnector 2 arranged at 90 ° to each other in the same switching device.
  • the arrangement of the drive means common to the intersection of the axis of translation of the contacts and within the same metal shell 3 makes it possible to maintain compact dimensions for the switching device.
