Transformer Oil Filtration and Dehydration Plant for High Voltage Power Transformer,
Used Transformer Oil Filter Machine
I. Application of Transformer Oil Filtration Machine
NSH VFD Vacuum Transformer Oil Dehydration Machine is designed to remove contaminants (particulate, water, gasses, etc.).Transformer oil maintenance is the key to transformer reliability, performance and longevity. Your transformer’s insulating oil should be free from moisture, dissolved gases and particles that accumulate as the oil ages. Even some new oils may require treatment to limit these contents to acceptable levels.
We Sino-NSH are a designing, engineering and manufacturing company capable of application customization for best solutions.
II. Working Principle of Transformer Oil Filtration Machine
Under the filtration of the multi-stage filter element, both large and small particle impurities are removed by filtration. The free water, micro-water and soluble water in the transformer oil will be removed by the high vacuum system at a constant temperature of 55-65 °C. At the same time, the gas in the transformer oil will also be removed.
III. Features of Transformer Oil Filtration Machine
1. Compact in structure, simple in operation
2. Convenient in maintenance, low cost
