TRANSFORMER COMPONENTS
—
3. Installation
Once the oil level in the device has been topped up,
the transformer may be started.
If there is no oil available for topping up, ABB
supplies a set of accessories with the pump which
can create a vacuum in the device, thus restoring the
oil level.
Instructions
The operations are performed as follows:
A) Remove the cap “2”, screw the valve “3” and its
nipple onto the tap “1”.
B) Remove the cap “4”, fit the pump “5” by means of
the threaded coupling provided and turn the lever
to OFF position.
C) The pump is already set to create a vacuum.
D) To restore the oil level inside the R.I.S. device,
open the lever of the tap “1” and suck with the
pump “5”. After this operation, close the lever of
the tap “1”.
E) Release air from the pump, turning the lever to
ON position.
If the oil level reached is not sufficient, repeat
operations “D” and “E”.
Once the operations are complete, remove the
components “5” and “3” and close the device with
the cap “2”.
