Suggestion
1. Check whether the expander, an
elastic element of the pressure
relief valve, does not work
smoothly, whether thin films are
damaged since the bolts securing
them are too tight or the pressure
relief valve opens, and whether
the sealing ring of the pressure
relief port is damaged (check
whether oil leakage occurs at the
port using a piece of paper or a
strip of white cloth), and check
the secondary loop and whether
the wire post and lead wire of the
gas relay are well insulated. If yes,
replace them or contact the
manufacturer.
2. When the transformer is being
repaired or installed, the oil
charge method is improper. As a
result, the gas in the upper part of
the conservator is not exhausted
as required. Power off the
transformer and refill it until the
oil is over the conservator. Then,
release oil to an appropriate level
by referring to the oil
temperature-oil level curve.
3. A short circuit fault usually affects
the gas relay from which you can
take the gas sample first.
4. Check the dampness of the silica
gel in the dehumidifier by its color
and whether the silica gel exceeds
2/3 of the dehumidifier. Check
whether the pipes are blocked by
filling nitrogen.
5. If the fault persists, contact your
dealer or technical support.
