Suggestion
1. Check whether the transformer is
overloaded. If yes, the high
winding temperature–induced
tripping occurs in some scenarios.
2. Check whether the circuit breaker
trips in error based on the cable
connection of the secondary loop.
3. Check whether the temperature
on the monitoring device is the
same as that on the winding
thermometer. If no, rectify the
fault on the winding thermometer.
4. If the fault persists, contact your
dealer or technical support.
1. If gas relay protection is available,
remove the trip circuit to prevent
accidental tripping.
2. O&M personnel need to check the
oil level gauge frequently. If the
oil level is too high, drain some
oil.
3. If the conservator or the
explosion-proof pipe sprays oil
abnormally, cut off the power
supply of the transformer
immediately to prevent the
escalation of fault and accident.
4. Check whether the pipes of the
dehumidifier/dehumidification
device are blocked. If yes, repair
the pipes.
5. Drain oil.
6. If the fault persists, contact your
dealer or technical support.
