Transformer Oil Purification



Transformers are the backbone of the power grid, and their reliability depends on rigorous maintenance. At Chongqing Weineng Oil Purification Solutions, we don’t just build equipment; we provide solutions for transformer longevity. This FAQ covers essential operational knowledge and highlights the critical role of transformer oil purification and vacuum dehydration systems in ensuring reliability.
1. What is the function of transformer oil?
A: It provides both cooling and insulation. To perform these functions effectively, the oil must be kept perfectly clean and dry. This is where a ZYD series transformer oil purification machine is essential, as it removes moisture, gases, and solid contaminants to maintain the oil’s dielectric strength.
7. What is the efficiency of a transformer?
A: Generally 95%–99%. However, this high efficiency can be severely compromised by contaminated oil, which leads to overheating and increased losses. Regular processing with an industrial vacuum transformer oil purification machine helps maintain optimal efficiency.
11. What is iron loss?
A: Losses in the core due to hysteresis and eddy currents. While these are inherent, moisture in the oil reduces the overall insulation resistance, which can exacerbate energy loss and heating.
17. What is the function of transformer oil?
A: Cooling and insulation. The key to preserving these functions is proactive oil maintenance. Our double-stage high-vacuum transformer oil purification machine are specifically designed to dehydrate and degas oil, ensuring its dielectric strength and cooling properties meet the highest standards.
23. What is the DGA (Dissolved Gas Analysis) test?
A: A diagnostic test that analyzes gases dissolved in the transformer oil to detect internal faults like arcing or overheating.
Key Insight: If the DGA test indicates moisture (H₂) or other fault gases, it is a clear sign that the oil needs immediate treatment. A mobile vacuum transformer oil purification machine can be deployed on-site to restore the oil quality, often preventing costly internal repairs and transformer downtime.
29. What is the effect of overloading?
A: It damages insulation and increases fire risk. Overloading also accelerates the aging of the insulating oil, causing it to sludge and lose its effectiveness. Using an online oil filter machine can help continuously clean the oil during periods of high stress, extending the life of both the oil and the transformer.
The Unsung Hero of Transformer Longevity: Oil Purification
As these FAQs demonstrate, the health of the insulating oil is directly linked to the health of the transformer itself. Waiting for test results to show failure is a reactive strategy. A proactive maintenance strategy with a reliable ZYD transformer oil purification machine machine is the most cost-effective way to:
- Prevent unexpected outages.
- Extend the operational life of your assets.
- Protect your investment in critical power infrastructure.
Don’t let contaminated oil be the weakest link in your power system.
