After the used transformer oil is regenerated, it can usually continue to be used, but it must meet the relevant quality standards. The specific analysis is as follows:
Resource recycling: Transformer oil contains a large amount of hydrocarbon components. Regeneration can effectively recycle and reduce resource waste.
Environmental protection: If the waste transformer oil is discharged directly, it will pollute the soil and water sources. Regeneration can reduce the emission of harmful substances and reduce environmental risks.
Economic benefits: The cost of regenerated oil is much lower than that of new oil, which can significantly reduce the operating costs of enterprises.
Physical regeneration: Remove impurities and moisture through filtration, adsorption and other processes to restore the insulation properties of the oil. For example, the use of adsorbents such as silica gel and activated clay can effectively remove acidic substances and resin aging products in the oil.
Chemical regeneration: Through chemical methods such as acid-base treatment and hydrogenation refining, the aging products in the oil are decomposed to restore the physical and chemical properties of the oil.
Vacuum distillation: In a high-temperature vacuum environment, the light components and pollutants in the oil are separated to achieve oil purification.
Quality standards: Regenerated transformer oil must meet national or industry standards, such as breakdown voltage, acid value, moisture content and other indicators that must meet the requirements. For example, the breakdown voltage should be greater than 35kV/2.5mm, and the acid value should be less than 0.1mgKOH/g.
Equipment adaptability: Regenerated oil is suitable for equipment with relatively low oil quality requirements, such as old transformers or non-critical equipment. For new equipment or high-voltage equipment, it is recommended to use new oil.
Additive supplement: During the regeneration process, antioxidants and other additives in the oil will be partially lost, and appropriate additives need to be supplemented according to the test results to extend the service life of the oil.
Pollution control: Pollutant emissions must be strictly controlled during the regeneration process to avoid secondary pollution.
Equipment maintenance: Regeneration equipment needs to be maintained regularly to ensure stable treatment effects.
Safety management: The storage and use of recycled oil must comply with relevant safety regulations to prevent fire and leakage accidents.
Power industry: Some power companies have applied recycled transformer oil to non-critical equipment, such as low-voltage transformers, with good operating results.
Industrial field: Some factories use recycled oil for hydraulic systems, lubrication systems, etc., reducing production costs.
Used transformer oil can usually continue to be used after scientific regeneration, but the regeneration process and quality control standards must be strictly followed. It is recommended to use recycled oil in non-critical equipment or places with low oil quality requirements, and regularly monitor its performance changes. For new equipment or critical equipment, it is still recommended to use new oil that meets the standards.
