- a second example can be given for a withstand voltage of 375 kV; in this case, the distance D between the Y axis and the face 18 would be 117 mm, the distance d between a free end 90 of the phase contact 14 facing the inside of the mounting plate 18 and the face 18 is 65 mm.
- the distance D therefore corresponds to the thickness of the grounding mechanism in the chamber. This appears to be relatively weak compared to the mechanism described in the document
- the present invention makes it possible to reduce the number of seals to be produced, and thus to reduce the risk of leakage of dielectric gas.
- the present invention also allows great freedom for the mounting and positioning of the earthing switch, and the configuration of the complete electrical equipment. We will now explain the operation of this disconnector according to the present invention.
- the shaft 64 is rotated by the drive means 62 disposed outside the housing 2 about its axis, causing the connection means 16 to slide towards the contact phase 14.
- the end of the rod 16 then enters the contact element 52.
- the rod 16 then provides the electrical connection between the earth contact 12 and the phase contact 14 ( Figure 2, dotted), and the grounding of the conductive bar 8 connected to the phase contact 14.
- the manufacturing method comprises the steps of: a) fixing on a mounting plate 6 at least one assembly comprising a ground contact 12, a phase contact 14 and a movable electrical connection means 16 between the phase contacts 14 and earth 12, b) fixing the mounting plate 6 on a housing 2 having at least one conductive bar 8.
- the connection of the phase contact 14 with the conductive bar 8 takes place automatically when mounting the mounting plate 6 on the housing 2.
