Transformer Oil Filtration Machine

Over time, transformer oil may contain many impurities (such as dust, sludge, free water), which will seriously affect the purity of the oil and may cause poor transformer performance and shorten machine life. To prevent this, we must maintain the transformer oil, filter, or purify the transformer oil with a transformer oil filtration machine.

We are one of the most competitive companies in the world specializing in the research and manufacture of high-tech oil purifiers. Our company annually produces 1,000 sets of oil filtration equipment and other purification machines.

How Should We Maintain Transformer Oil? 

Purify Transformer Oil with Transformer Oil Filtration Machine

Transformer oil plays the role of coolant, insulating oil, and safety protection device in transformers. Its dielectric strength and chemical composition can directly affect the performance of the transformer. But if the oil contains a small amount of moisture and impurities, it will reduce the dielectric strength. At the same time, if the oil is in contact with oxygen, the oil will be easily oxidized and deteriorated at high temperatures.

However, after the transformer oil is highly refined by the transformer oil purifier, it can run stably at high temperatures and has excellent electrical insulation properties.

Therefore, clean transformer oil is essential for the safe and efficient operation of various electrical equipment such as power transformers, instrument transformers, circuit breakers, and high-voltage bushings. Therefore, we should learn to use the transformer oil purification machine properly.

Detection And Analysis of Transformer Oil

In order to prevent the deterioration of the oil quality and affect the safe operation, the oil distribution samples in normal operation should be regularly tested and analyzed, and the oil should be processed according to the analysis results. The oil chemical supervision and inspection cycle for distribution operations is stipulated at least once every three years.

The Process of Transformer Oil Filtration We Should Know

There Are 3 Kinds of Oil Treatment Processes:

  1. Physical Settling: This process filters fine pollution particles through a filtration unit. Removal of visible solid impurities in transformers by physical sedimentation.
  2. Dry Purification: Heat the oil to a maximum of 90 degrees Celsius to remove the acidic and polar parts of the transformer oil. Moisture or other liquid impurities in transformer oil are removed by desiccants or other additives;
  3. Reclamation or Regeneration with Degassing: Reclamation or regeneration with degassing is similar to dry purification but uses an additional oxidant.

Transformer oil treated by these three processes can achieve the performance of base oil.

The above oil treatment process can be completed by China oil purifier‘s transformer oil filtration device. It is safer and more efficient to use the oil purification machine to filter/purify and can meet the relevant cleaning standards.

Why Choose China Oil Purifier?

The Role of The Oil Purifier We Provide:

It removes oxidative substances from the oil, extending the life of antioxidants and additives.

It can remove particles, water, gas, acid, and other substances in transformer oil without destroying the original additives of the oil and maintaining its original performance.

In addition, the machine can withstand high temperatures below 300 °C and adopts a fully enclosed model, which is safe and environmentally friendly.
