Transformer Oil Filtration Machine

After the transformer oil is highly refined through the transformer oil filtration machine, it can run stably at a high temperature and has excellent electrical insulation properties. Transformer oil acts as a coolant, insulating oil and safety protection device in the transformer. Clean transformer oil is essential for the safe and efficient operation of many types of electrical equipment such as power transformers, instrument transformers, circuit breakers and high-voltage bushings. However, transformer oil contains many impurities (such as dust, sludge, and free water), which seriously affect the purity of the oil. This may lead to poor transformer performance and shortened machine life. To prevent this, maintenance must be performed on the transformer oil.

 

Chongqing YUNENG Oil Purifier Manufacturing Co., Ltd. provides a variety of transformer oil filtration machines that can remove oxidizing substances in the oil, thereby extending the life of antioxidants and additives. Remove particles, water, gases, acids and other substances from transformer oil without damaging the original additives of the oil and maintaining its original properties. In addition, the machine uses a fully enclosed model, which is safe and environmentally friendly. The machine can withstand high temperatures below 300℃, and completely remove free water from oil.

Why Transformer Oil Filtration is Important?

  • Transformer oil is the main insulation and cooling medium of oil-immersed transformers. Its dielectric strength and chemical composition directly affect the performance of the transformer. If the oil contains a small amount of moisture and impurities, it will reduce the insulation strength; and the oil is in contact with oxygen, it is easy to oxidize and deteriorate at high temperatures. Therefore, the transformer oil filtration machine should be carried out when the transformer is installed.

 

  • To prevent the deterioration of the oil quality and the impact on the safe operation, the regular oil distribution samples for normal operation should be tested and analyzed, and the oil should be processed according to the analysis results. The inspection cycle of oil chemical supervision for distribution operation is specified to be at least once every three years.

 

 

Transformer Oil Filtration Process

The transformer oil filtration process involves filters the transformer oil at a temperature of about 40 degrees Celsius. There are three types of oil treatment processes:

 

Physical settlement: This process filters fine polluted particles by filtration unit. Remove solid impurities visible in transformers by physical settlement;

 

Dry and purification: Heat the oil to 90 degrees with the highest Celsius and remove acidity and polar part from the transformer oil. The water or other liquid impurities in the transformer oil are removed by desiccant or other additives;


Reclamation with Degassing or Regeneration: Reclamation with Degassing or Regeneration is similar to dry purification, but an additional oxidant is used.

 

The transformer oil processed by these three processes can reach the properties of base oil. Transformer oil filtration can complete the above oil treatment process by transformer oil filtration plant. Filtering is safer and efficient using an oil filtration plant and can achieve relevant cleaning standards.

An Overview of Transformer Oil

The function of transformer oil:

As cooler: When the voltage rises or falls, the temperature of the transformer windings rises, and the oil is used in the cooling state.

As insulator: It acts as an insulator between the windings, increases the resistance between them and avoids short circuits.

For Safe: The oil temperature display describes the internal condition of the transformer and displays any short-circuit state. In this way, the transformer can be prevented from suffering from severe loss and damage.

 

 

Treat with transformer oil filtration:

The transformer requires filtered and dried oil. Insulating oil will absorb moisture during use and is contaminated by some particulate impurity. Besides, the dissolved gas will cause arc, corona discharge and overheating, thereby reducing the electrical efficiency and life of the transformer. Granular pollution will also affect the function of insulating oil. In order to treat and purify the insulating oil, the transformer oil needs to be filtered. Transformer oil filtration is a process of degreasing, dehydrating, and polluting from transformer oil.
