Comprehensive Testing and Quality Assurance for 5000 kVA Transformers
During the production of the 5000 kVA transformer, strict testing procedures are a critical step to ensure product quality and safety. Each transformer undergoes a series of electrical, mechanical, and temperature-rise tests to verify that its performance meets the design specifications. These tests include load loss testing, no-load loss testing, and short-circuit impedance measurements, all aimed at ensuring the transformer delivers efficient energy transmission and low loss during actual operation. The results of these tests directly impact the transformer’s stability, lifespan, and operational efficiency, making them an indispensable part of the production process.
In addition, all tests strictly adhere to current electrical testing regulations and industry standards, ensuring the transformers comply with international certifications such as ANSI/IEEE, CSA, and UL standards. After the tests are completed, detailed records are kept, and comprehensive test reports are provided based on customer requirements. This not only guarantees the safety and reliability of the transformers but also offers customers peace of mind in their use. Through these rigorous quality control measures, Yongxing Transformer ensures that every 5000 kVA transformer is fully validated before leaving the factory, meeting the demands for high-load operation.
お問い合わせMaintenance of 33kV 5000 KVA Power Line Transformer
Proper maintenance is crucial for maximizing the lifespan and operational efficiency of your 34.5kV 5000 KVA power line transformer. Here’s an extended guide to comprehensive transformer maintenance, designed to minimize unplanned downtime and enhance long-term performance:
1. Visual Inspection
- Objective: Ensure that the external transformer components are intact.
- Action:
- Regularly inspect the tank, bushings, tap changer, and bushings for cracks, rust, or corrosion. Any visual defects or leakage spots should be addressed immediately.
- Clean the transformer housing regularly to remove accumulated dust and debris, especially in areas with high pollution or industrial dust.
2. Insulation Integrity
- Objective: Maintain the insulation’s performance to prevent electrical faults.
- Action:
- Check for insulation degradation. This includes inspecting insulating oil for discoloration, signs of contamination, or reduced insulating capacity.
- For liquid-immersed transformers, check the oil level and look for signs of air bubbles or foam, indicating potential issues with seals.

3. Oil Quality Monitoring
- Objective: Ensure optimal performance of the insulation and cooling system.
- Action:
- Periodically sample the transformer oil to check for moisture, contaminants, and its dielectric strength.
- If oil quality is compromised, conduct an oil filtration process or replace the oil as necessary.
- Regularly inspect the oil temperature using a Qualitrol monitoring system to ensure it remains within safe operating ranges.
4. Thermal Management
- Objective: Prevent overheating and ensure effective cooling.
- Action:
- Monitor the oil temperature and ensure it stays within the recommended limits for ONAN and ONAF operation.
- Check the cooling fans (in ONAF configurations) to ensure they’re functioning properly. Malfunctioning fans can significantly reduce cooling efficiency and overload the transformer.
5. Load Testing and Voltage Regulation
- Objective: Ensure the transformer operates under optimal load conditions and maintains accurate voltage regulation.
- Action:
- Verify that the transformer maintains proper voltage levels at varying loads, especially under extreme conditions.
- Test the voltage regulator (if applicable) for correct adjustment and proper operation. In the case of five-level voltage regulation, verify that the output voltage is within the desired range (33.53kV to 36.62kV for ±2.5% regulation or 32.78kV to 36.23kV for ±5% regulation).
6. Overcurrent and Short-Circuit Protection
- Objective: Protect the transformer from damage caused by overcurrent or faults.
- Action:
- Ensure that overcurrent protection devices, such as circuit breakers, are properly calibrated and functional.
- Inspect pressure relief devices to make sure they’re not blocked and can vent excess pressure in case of faults.

7. Safety Checks
- Objective: Ensure the transformer is safe to operate.
- Action:
- Examine the grounding system and safety barriers around the transformer to ensure they meet safety standards.
- Regularly inspect lightning arresters and ensure proper grounding to protect the transformer from voltage surges caused by lightning strikes.
8. Documentation and Preventive Maintenance
- Objective: Track performance and maintenance history for proactive care.
- Action:
- Keep a maintenance log documenting every inspection, test, and repair. Include specifics such as dates, the personnel involved, and actions taken.
- Regularly review maintenance records to identify trends that might indicate underlying issues.
