AI Overview
), extending the life of high-voltage equipment.
Key Features and Components
- High Vacuum Technology: Uses double-stage or single-stage vacuum pumps to achieve vacuums often below , efficiently removing water toand gases to.
- Multi-Stage Filtration: Incorporates pre-filters for large particles and fine filters (down to or lower) for removing solid contaminants.
- Heating System: Heats the oil to enhance water and gas removal, usually under vacuum, using optimized heating elements to prevent oil degradation.
- Degassing Chamber: Features special sprayers or packed columns to increase the oil surface area for maximum degassing efficiency.
Types and Applications
- Portable/Mobile: Trailer-mounted units with weatherproof enclosures are designed for on-site, on-load, or off-load maintenance at substations.
- Stationary: Fixed-configuration plants (e.g., Ekofluid's ECOIL 5000) are suited for workshop environments.
- Applications: These plants are used on transformers, reactors, and circuit breakers, ensuring dielectric oil complies with standards like IEC 60422.
Key Benefits
- Improved Oil Quality: Significantly raises dielectric strength (breakdown voltage) to after treatment.
- Cost-Efficient: Extends the life of insulating oil, reducing the need for expensive oil replacement.
- Versatility: Capable of transformer oil purification, vacuum drying of transformers, and oil filling.
