Fig. 2.3.4.7.9 Bolt the
base plate of voltage
transformer to the
frame
Step 5
Bolt the voltage transformer on the support roof
as shown in figure 2.3.4.7.5.
Check the transformer for damage prior
to installation.
If you note any damage on the transformer,
only use the component after this has
been agreed with ABB Service
Department.
•
The surface of the cone must be free of:
- gas bubbles.
- scoring.
- damage.
- abrasions.
- foreign bodies.
Cleaning of soiled cone surfaces
Clean the cone of the transformer immediately
prior to installation as follows
:
•
Remove surplus or dirty grease from the cone
surface with a soft, clean, non-fraying cloth.
Only use intensive cleaner M.X.T. 60
forte as the cleaning agent.
•
Clean the surface of the cone with the cleaning
agent and a soft, clean, non-fraying cloth.
•
After cleaning with intensive cleaner M.X.T. 60
forte, wipe the surface of the cone with a dry
cloth.
Cleaning the busbar adapters
Only use intensive cleaner M.X.T 60 forte
as the cleaning agent.
•
Clean the silicone surface with the cleaning
agent and a soft, clean, non-fraying cloth.
•
Only moisten the cloth slightly with intensive
cleaner. Apply only moderate pressure when
cleaning the silicone surfaces.
•
After cleaning with intensive cleaner M.X.T. 60
forte, wipe the silicone surtace with a dry cloth.
Greasing the cones
•
Grease the cone of the transformer and the
cone of the adapter lightly, evenly and
completely with assembly paste (part number
1VB0000207P0101)
Installation the voltage transformers
Use the eyebolts supplied for lifting of the voltage
transformer. Screw the eyebolts into the threads
in the cast resin body of the voltage transformer
and lift it using a suitable hoist.
Position the voltage transformer above the
corresponding busbar adapter. Lower the
voltage transformer slowly and evenly, guiding
the silicone insulating part of the transformer
into the cone of the busbar adapter.
Bolt the base plate of the voltage transformer to
the frame as shown in figure 2.3.4.7.9.
