The key points of maintenance for epoxy resin cast dry type transformers
1. Maintain cleanliness: Regularly remove dust.
2. Control temperature: Ensure the cooling system is functioning properly and monitor the temperature rise to avoid
exceeding the limit.
3. Ensure tightness: Prevent electrical connection points from loosening and overheating.
4. Keep the environment dry: Prevent insulation from getting damp.
5. Conduct regular tests: Discover potential problems in advance through preventive tests.
Common Faults and Their Solutions
| Fault phenomenon | Possible reasons | Solution method |
| Excessive temperature rise |
1. Long-term overloading 2. Fan failure or air duct blockage 3. Inter-turn short circuit inside the winding 4. Poor contact at connection points |
1. Load reduction operation 2. Repair the fan and clean the air duct 3. Power off for winding repair 4. Re-tighten the connection points |
| Abnormal noise |
1. The iron core clamps or fasteners are loose. 2. Winding loosening 3. Excessive voltage |
1. Tighten loose components 2. Send to the factory for maintenance 3. Adjust the grid voltage |
| Insulation resistance decreases |
1. Moisture absorption 2. Severe contamination on the insulation surface 3. Insulation aging |
1. Conduct dehumidification treatment 2. Thorough cleaning 3. Consult the manufacturer |
| The fan is not rotating. |
1. Power failure 2. Motor damage 3. Thermal relay activation |
1. Check the control loop 2. Replace the fan 3. Reset and investigate the cause |
