How to use the transformer vacuum oil filter?

Using a transformer vacuum oil filter involves several steps to ensure the effective purification of transformer oil. Below is a detailed guide on how to operate the equipment safely and efficiently:

 1. Preparation

 1.1. Safety Checks

- Read the Manual: Familiarize yourself with the equipment’s operating instructions and safety guidelines.

- Inspect the Equipment: Check for any visible damage, leaks, or loose connections.

- Ensure Proper Grounding: Verify that the equipment is properly grounded to prevent electrical hazards.

 1.2. Setup

- Position the Filter: Place the vacuum oil filter on a stable, level surface near the transformer.

- Connect Hoses: Attach the inlet and outlet hoses to the transformer and the filter unit. Ensure all connections are secure and leak-free.

- Power Supply: Connect the equipment to a suitable power source, ensuring the voltage matches the equipment’s requirements.

 2. Initial Setup

 2.1. Fill the Oil

- Pre-Fill the Filter: If required, fill the filter unit with clean oil to prime the system and avoid airlocks.

- Check Oil Level: Ensure the transformer has sufficient oil for the filtration process.

 2.2. Set Parameters

- Adjust Temperature: Set the heating system to the recommended temperature (typically 50-60°C) to enhance moisture and gas removal.

- Vacuum Level: Set the vacuum pump to the desired level (usually between 0.5 to 1 mbar) for optimal performance.

 3. Start the Filtration Process

 3.1. Turn On the Equipment

- Start the Vacuum Pump: Activate the vacuum pump to create a negative pressure in the system.

- Start the Oil Pump: Turn on the oil pump to begin circulating oil through the filter.

 3.2. Monitor the Process

- Check Flow Rate: Ensure the oil is flowing at the recommended rate (refer to the equipment manual).

- Monitor Temperature: Keep an eye on the oil temperature to avoid overheating.

- Observe Vacuum Levels: Ensure the vacuum level remains stable and within the desired range.

 4. Filtration and Purification

 4.1. Remove Contaminants

- Solid Particles: The filter elements will trap solid impurities as the oil passes through.

- Moisture and Gases: The vacuum system will remove moisture and dissolved gases from the oil.

 4.2. Continuous Monitoring

- Check Oil Quality: Periodically test the oil for moisture content, gas levels, and particulate matter.

- Adjust Settings: If necessary, adjust the temperature, vacuum level, or flow rate to optimize performance.

 5. Shutdown and Post-Processing

 5.1. Stop the Equipment

- Turn Off the Oil Pump: Once the filtration process is complete, stop the oil pump.

- Turn Off the Vacuum Pump: Allow the system to return to atmospheric pressure before shutting down the vacuum pump.

- Turn Off Heating: Disable the heating system and allow the oil to cool.

 5.2. Disconnect and Clean

- Disconnect Hoses: Carefully disconnect the hoses from the transformer and the filter unit.

- Drain the Filter: If necessary, drain any remaining oil from the filter unit.

- Clean the Equipment: Clean the filter elements and other components as per the manufacturer’s instructions.

 6. Final Checks

 6.1. Inspect the Oil

- Test the Oil: Perform final tests to ensure the oil meets the required standards for moisture content, gas levels, and cleanliness.

- Record Results: Document the oil quality parameters for future reference.

 6.2. Restore the Transformer

- Refill the Transformer: If oil was removed during the process, refill the transformer with the purified oil.

- Check for Leaks: Inspect the transformer and connections for any leaks or issues.

 Safety Tips

- Wear Protective Gear: Use gloves, goggles, and protective clothing to avoid contact with hot oil or chemicals.

- Avoid Overheating: Monitor the oil temperature to prevent overheating, which can degrade the oil.

- Follow Manufacturer Guidelines: Always adhere to the equipment manufacturer’s instructions for operation and maintenance.

 Conclusion

Using a transformer vacuum oil filter involves careful preparation, monitoring, and post-processing to ensure effective purification of the oil. By following these steps, you can maintain the quality of the transformer oil, extend the life of the transformer, and ensure reliable operation of the electrical system. Always prioritize safety and adhere to the equipment’s operating guidelines.
