Filtering impurities from transformer oil is an important step to ensure the normal operation of the transformer and extend its service life. The following are several common filtering methods and their operating steps:
- Principle: Use filter paper, filter screen and other filter media to remove solid particle impurities in the oil by physical interception.
- Equipment: Plate and frame oil filter, pressure oil filter.
- Advantages: Simple operation, low cost, suitable for removing larger particle impurities.
- Principle: In a vacuum environment, use filter paper or filter cloth to filter impurities in the oil, and remove moisture and gas at the same time.
- Equipment: Vacuum oil filter.
- Advantages: Efficient and thorough, suitable for removing tiny particles and moisture.
- Principle: Use the centrifugal force generated by the high-speed rotation of the centrifuge to separate the solid particles and moisture in the oil.
- Equipment: Centrifugal oil filter.
- Advantages: Fast processing speed, suitable for oil with high impurity content.
- Principle: Use adsorbents (such as activated clay, and silica gel) to absorb tiny particles and colloidal substances in the oil.
- Equipment: Adsorption oil filter
- Advantages: It can effectively remove tiny particles and colloidal substances and improve the purity of the oil.
- Principle: Small particles are gathered into large particles through a coalescer, and then separated by gravity or centrifugal force.
- Equipment: Coagulation oil filter.
- Advantages: Suitable for oil treatment with micro-particle content.
1. Detect oil quality: Use an oil quality tester to determine the type and content of impurities in the oil.
2. ｓｅｌｅｃｔ the appropriate method: ｓｅｌｅｃｔ the appropriate method and equipment according to the type and content of impurities.
3. Pretreatment: Remove large particle impurities through the primary filter to protect subsequent filtration equipment.
4. Filtration treatment: Perform filtration treatment according to the equipment operation manual.
5. Detect treatment effect: Detect the oil quality after treatment to ensure that it meets the requirements.
- Safe operation: Pay attention to fire prevention and explosion prevention during the processing, and avoid high temperatures and open flames.
- Regular maintenance: Regularly check and maintain the oil filter equipment to ensure its normal operation.
- Environmental protection treatment: The treated waste oil and waste filter materials should be properly handled by environmental protection requirements.
Through the above methods, impurities in transformer oil can be effectively filtered, maintaining the normal operation of the transformer and extending its service life.
