Notes on Transformer Oil Filtration

Transformer oil filtration is an important step in maintaining transformer performance. The following matters need to be noted:

1. Safety measures

- Power-off operation: Ensure that the transformer is powered off and grounded to avoid electric shock.

- Fire and explosion prevention: Keep the filtration equipment away from fire sources and equip fire extinguishers on site.

- Personal protection: Operators should wear protective equipment to avoid oil contact with the skin.

2. Equipment inspection

- Filtering equipment: Ensure that the equipment is clean, impurities-free, and the filter element is intact.

- Oil quality detection: Detect the oil quality before filtration to determine the filtration requirements.

3. Filtration process

- Temperature control: Keep the oil temperature at 40-60℃. Too high or too low will affect the effect.

- Filtration speed: Control the appropriate speed. Too fast may lead to incomplete filtration.

- Multiple filtration: When the oil quality is poor, multiple filtrations are required to meet the standards.

4. Oil quality detection

- Post-filtration detection: Detect the oil quality after filtration to ensure that it meets the standards.

- Record data: Record the oil quality data before and after filtration for subsequent analysis.

5. Equipment maintenance

- Cleaning equipment: Clean the equipment after filtering to prevent oil residue.

- ｒｅｐｌａｃｅ filter element: ｒｅｐｌａｃｅ the filter element regularly to ensure the filtering effect.

6. Environmental protection

- Waste oil treatment: Waste oil is treated according to environmental protection requirements to avoid pollution.

- Site cleaning: Clean the site after the operation to prevent oil residue.

7. Operating specifications

- Operate according to the regulations: Strictly follow the operating procedures to avoid misoperation.

- Trainers: Operators must be trained and familiar with the process and safety requirements.

8. Records and reports

- Recording process: Record the filtering process, equipment status and oil quality data in detail.

- Write a report: Write a report after the operation to record problems and improvement suggestions.

9. Regular maintenance

- Regular filtration: Arrange oil filtration regularly according to the operation of the transformer.

- Preventive maintenance: Extend the life of the transformer and reduce failures through regular filtration.

Following these precautions can ensure the safety and effectiveness of transformer oil filtration and improve the reliability of equipment operation.
