Poles coupling regulation lies in such a setting of the length of the tie rod and coupling lever location adjust-
ment so that the current paths at each pole reach the limit positions according to the following requirements.
Regulation process should be performed in following way:
a) initially coupling tie rods should be installed in such a way that one pole would not be connected (tie rod
ending hang on a line, below coupling lever),
b) coupling tie rod should be extended or shortened in such a way that current path in driving pole would
achieve require limit positions. If tie rod length change forecloses achievement of the limit positions driving
lever position should be changed on driving pole. The next figure presents the behavior of the disconnector’s
poles when changing the position of the drive lever while maintening the same length of tie rod. After changing
the position of the lever it is necessary to correct the length of the tie rod and check the limit positions of the
current path.
c) after finishing one pole’s coupling regulation it is permitted to tighten up tie rod to the last pole and repeat
steps from subpoint b.
