3.1 Assembly of the pole (Ref. Fig 4, page no.53)
1. Clean all the components used in the pole.
2. Interrupter Assembly: -Insert the plug for lamellar contact 10203 on the stem of the
interrupter. Maintain the distances B and C as shown in fig.4, page no. 53 and
tighten the assembly by applying proper torque. Fix the lamellar contact 10003
and guide ring 10202 in proper grooves provided on the plug 10203. Lubricate plug
and lamellar contact with contact grease.
3. Now, insert the interrupter assembly in current collector hub 10018, which is fixed
on lower terminal plate.
4. Fix the operating stud 10100 from the other side of the lower terminal plate.
5. Hold the vacuum interrupter 10204 in a firm position and tighten the operating stud
10100 firmly with proper torque. Negligence in holding the moving contact of the
vacuum interrupter may damage the bellow of the vacuum interrupters.
6. Now, insert the O-ring (big) 10005 and O-ring (small) 10004 on the respective
sides of the lower terminal plate 10009 and apply sealing grease.
7. Lift the support insulator and place it over duct, attach it temporarily to duct with
nuts and bolts.
8. Insert the operating stud with rubber bellow inside the suppor t insulator and place
lower terminal plate and interrupter over support insulator.
9. Lift the top insulator and put it over the lower terminal plate, Engage lower terminal
plate and insulator flanges by using nut bolts.
10. Cover the top insulator by top terminal plate, before that fix O-ring 10005 on the
top terminal plate and apply sealing grease. Engage it with flange of top insulator
by appropriate hardware; eyebolts 10020 must be placed at their original position.
11. Fix the bolt 10015 on the top terminal plate 10009, which firmly holds the
interrupter. Initially keep this bolt loose till the relaxation of the contacts takes
place.
12. Perform 5-10 manual operations on the poles by pulling the operating stud down
for relaxation and alignment of the whole assembly. This will ensure the setting of
lamellar contact assembly in the current collector hub.
13. Tighten the bolt 10015 on the top terminal plate with a torque of 90 Nm. Tighten
all nut bolts except used for duct and support insulator fixing with torque of 67 Nm.
14. Now remove the hardware used for fixing support insulator and duct, lift the pole
upwards and take the rubber below between bottom flange and duct and tighten
it with proper hardware.
