The properly mounted contact of the earthing switch is shown on the next drawing.
3.12. Assembling and adjustment of the knife of the earthing switch.
The adjustment is carried out as follows:
a) one should assembly the bearing sleeves [1] in the disconnector’s base frame, and then adapt the diameter
of the holes to the diameter of the crank (it is allowed to increase the diameter using, for example, a flap wheel
on the drill). The length of the coupling tie rod [2] should be adjusted in such a way that the crank [3] turns sym-
metrically in relation to the axis of the supporting insulator, according to the following graphics. Adjustments
should be made visually.
