Definitions

  • the invention relates to a module for electrical switchgear, comprising a vacuum bulb and means for fixing the bulb to a support frame. It also relates to an apparatus comprising at least one such module.
  • a vacuum interrupter comprises a body forming a sealed enclosure and enclosing a pair of separable contacts, with at least one movable contact.
  • the movable contact is secured to a metal rod movable in translation parallel to its axis and projecting at a first axial end of the bulb.
  • a seal is made between the rod and a wall of the enclosure, by means of a bellows allowing the translational movement of the rod.
  • This rod is intended to be connected to a drive mechanism of the bulb.
  • the other contact is in general a fixed contact secured to a fixed rod which passes through the body of the bulb, so as to be accessible from the outside to a second axial end of the bulb, opposite to the first.
  • the movable rod is guided in its axial movement relative to the bulb through a guide sleeve integral with the body of the bulb and projecting inwardly of the bulb.
  • a guide sleeve integral with the body of the bulb and projecting inwardly of the bulb.
  • each phase comprises a vacuum bulb of the type described above, supported by a rigid frame of insulating material.
  • the body of the bulb On the side of the first axial end, the body of the bulb is fixed to the frame by means of a support plate provided with a bore with the diameter of the first axial end, and forming a seat for the body of the bulb.
  • the body of the bulb On the side of the second axial end, the body of the bulb is fixed to the frame by means of a fixed rod fixing nut to an electrical connection range secured to the frame. There is no interaction between the support plate and the rod.
  • the bonding operation of the bonding necessarily takes place after the bulb has been mounted on the support plate, since the bonded connection is too large to pass through the bore of the plate support. Furthermore, the positioning of the bulb on its frame must be performed accurately, so as not to solicit the rod of the movable contact out of its axis of translation determined by the inner guide sleeve to the bulb. These points prove disadvantageous during the industrialization of the equipment.
  • An object of the invention is to facilitate the assembly of electrical switchgear vacuum interrupter, including the break module constituted by the bulb and its support frame.
  • the collar allows both the guiding of the rod relative to the bulb and the fixing of the bulb relative to the frame.
  • the chain of dimensions is reduced, resulting in greater guiding accuracy, provided at low cost.
  • the frame is provided with guide rails and the collar is slidably shaped so as to slide in said guide rails, in a direction perpendicular to the geometric axis of the light. It is then possible to assemble the bulb and its collar, before inserting the assembly in the frame, by sliding the collar in the slides.
  • the fastening means comprise elastic clips forming a fastening by clips. This fastening mode by staples makes mounting particularly simple.
  • the staples are preferably located on the collar, and cooperate with supports located on the frame.
  • the collar is composed of two parts able to take one relative to the other an open position allowing the radial insertion of the stem of the bulb and a closed position ensuring the cooperation of the radial positioning surfaces with the body of the bulb, and light with the stem.
