Q: What should be done if the transformer's cooling system fails?
A:
If fans or oil pumps stop working, immediately check the power supply and control circuit. Start standby cooling equipment if available. Reduce the transformer load to lower temperature; shut down immediately if the top oil temperature exceeds 95℃ to avoid insulation damage due to overheating.
Q: What factors can affect the service life of 11kV-33kV three-phase oil-immersed distribution transformers?
A:
Key factors include long-term overload operation (accelerates insulation aging), poor oil quality (oxidation or moisture intrusion), harsh environment (corrosion, high humidity), frequent voltage surges, and inadequate maintenance. Proper load control and regular maintenance can extend its service life to 20-30 years.
