Vacuum oil filter is a product for on-site oil filtering and oil replenishment for various oil-immersed transformers, oil-immersed current and voltage transformers, and high-voltage oil-less circuit breakers
.

The main purpose of vacuum oil filter and transformer oil filter

1. It can be used for on-site oil filtering and oil replenishment for various oil-immersed transformers, oil-immersed current and voltage transformers and high-voltage oil-less circuit breakers.

2. It can be used for on-site thermal oil circulation drying of the above-mentioned equipment, especially for the on-site thermal oil circulation drying of oil-immersed current, voltage transformer and high-voltage oil-less circuit breaker.

3. It can be used for on-site vacuum oil filling and replenishment of sealed oil-immersed equipment and equipment vacuuming.

4. It can also be used to regenerate and purify mildly deteriorated transformer oil, so that its performance can reach the standard of qualified oil.

5. It can also be used in power plants, power stations, power companies, power transformation industry, metallurgy, petrochemical, machinery, transportation, railway and other industries.

The quality level achieved by the full flow one-pass oil purifier:

1. Dielectric strength: The dielectric strength can be improved to 70KV, which meets the new oil standard.

2. Dewatering: After the first filtration, the water content drops from 50ppm to below 5ppm; after the second filtration, it drops to 3ppm. (measured according to ASTM standard D-1533 method)

3. Degassing: from the full saturation content of air (10-12% of the volume) to below 0.1% of the volume (measured according to ASTM standard D-2945 method)

4. Removal of particles: 98% of particles above 0.5 microns, or particles above 1 or 5 microns according to user requirements can be removed

5. Flow rate: 300-liter/hour product series are available.

2. Process and technology

1. Oil spray:

The transformer oil filter is a key link in the rapid removal of moisture and gas pollution. It uses a porous media filter cartridge called a coalescer. In this process, heated or unheated oil passes through a bonded glass fiber layer, and the glass fiber Thousands of sharp edges cut the oil and expose it to the vacuum. The oil is sprayed as soon as it passes through the coalescer, which improves the filtration efficiency and allows oil treatment even when the oil temperature is only 20°C.

2. Oil filtration:

The filter element is made of non-migrating fiber material, which is characterized by a large surface area and high dirt interception capacity. The outstanding features of the filter element type filter are low filtration cost, easy and quick replacement of the filter element, no loss of oil, and no need for backwashing time.
