Definitions

  • the present invention relates to a whip that can be used for a high-voltage disconnector, in particular with a vertical opening, comprising a flexible metal rod.
  • An object of the present invention is to define a whip having a larger section in the electrical contact zone, while retaining good flexibility.
  • Another object of the invention is to produce a whip having a greater lateral rigidity than the whips of the known art.
  • Another object of the invention is to produce a more economical construction whip than that of the whips of the prior art.
  • the whip of the invention which can be used for a high-voltage disconnector, in particular with a vertical opening, comprising a flexible metal rod, characterized in that the section of the whip is a truncated circle whose surface gradually decreases from the base. at the tip of the whip.
  • the section of the whip varies from 80% to 50% of the section at the base of the whip.
  • a high voltage disconnector comprising an insulating column 1 placed on a metal frame 2; a female contact 3, in the shape of a tulip, is fixed to the end of a metal support 4, placed at the end of the column 1, and carrying a socket 5.
  • a male contact 6 is fixed to the end of an operating arm 7 associated with an operating mechanism 8 actuated by a motor contained in a box 9 and which drives a transmission arm 10.
  • the mechanism is arranged to communicate to the operating arm 7, during an operation opening the disconnector, first a translational movement along its axis to allow the separation of the contacts 3 and 6, then a rotational movement in a vertical plane, allowing the arm to come occupy a position 90 ° from the initial position, as shown in dotted lines in FIG. 1.
  • a metal braid 11 connects the arm 7 to the frame 2 grounded.
  • the disconnector is provided with a whip 16, fixed at a fixed point 18 of the arm 7, and subject to remain, during an opening operation, in electrical contact with a part mechanically integral with the female contact 3 and electrically connected to the latter; this is obtained by means of a guide piece 17 fixed to the support 4 by bolting 15.
  • a piece 19 limits the angle between the whip 7 and the arm 15 during the disconnector opening phase.
  • Figure 3 illustrates a whip of the prior art, of circular section gradually decreasing from the base to the end; seven equally spaced sections were shown and their S values in mm 2 were indicated.
  • the segment AB represents the electrical contact area of the whip.
  • FIG. 4 illustrates a whisk according to the invention, and the same sections are shown with their values in mm 2 .
  • the sections are truncated circles, that is to say amputated from a part delimited by a rectilinear secant; the whip therefore has a flat surface.
  • the section of the whip of the prior art is between 67% and 40% of the section of the base of the whip, while in the same contact area , the section of the whip of the invention ranges between 80% and 55% of the section of the base.
  • the section of the whip, in the electrical contact area is of the order of 16% to 36% greater than the section of the conical whip in the same area. This results in a better capacity for transferring electric current.
  • Measurements in electrostatic induction test have shown that the breaking capacity of the whip of the invention is greatly increased compared to the breaking capacity of the whip of the prior art, so that at equal current, the whip of the invention has reduced wear and , consequently, a longer longevity.
  • FIGS. 3 and 4 have also shown, for the whip of the prior art and for the whip of the invention, the moments of inertia lx and ly expressed in mm4, x and y designating two perpendicular directions in a section, x being parallel to the above secant. It can be seen from reading the figures that the whip of the invention has a lateral rigidity greater than the conventional conical whip, which results in limited lateral movements.
  • the whisk of the invention can be machined on conventional machine tools more economically than the conical whisk of the prior art, for example by means of a conventional milling machine instead of a complicated machine. This results in a cost price which can be divided by a factor of up to 4.
  • the invention finds application in the equipment of high voltage disconnectors, in particular disconnectors with vertical opening, that is to say in which the operating arm moves in a vertical plane.
