The Transformer Oil Filtration Machine is specifically designed for the purification and regeneration of insulating oil during the installation and maintenance of large-scale power transformers. It is widely used in 330kV to 1000kV high-voltage and EHV transformers, ensuring effective hot oil circulation and vacuum drying in demanding field environments.
This system is capable of deep purification for new high-grade insulating oil and imported transformer oil. Through integrated processes such as vacuum dehydration, degassing, acid value reduction, free carbon removal, and final stage polishing, the oil's dielectric strength is significantly enhanced, often reaching values close to new oil standards.
In addition to filtration, the unit also includes an independent vacuum system that supports vacuum drying and oil filling for transformer equipment. Its dual functionality makes it ideal not only as a purification tool, but also as an online oil filtration system during energized maintenance or pre-commissioning operations.
The Vacuum Oil Filtration Machine operates based on a multi-step purification process that includes vacuum separation, precision filtration, spiral spray atomization, molecular adsorption, and vacuum drying. These combined technologies enable the efficient removal of moisture, gases, acids, and particulate contaminants from insulating oil.
After treatment, the oil quality fully meets or exceeds national standards for dielectric strength and cleanliness. This system is also designed to function as an online transformer oil filtration system, allowing real-time purification during transformer operation without interrupting service, making it ideal for power utilities and substation maintenance.
