Transformer Oil Filtration Unit Manufacturer in China

• Why do we need to filter transformer oil regularly？

The purpose of transformer oil filtration is to remove moisture and impurities in the oil and improve the breakdown voltage of the oil.

It protects the paper insulation in the oil, and can also improve the physical and chemical properties of the oil to a certain extent.

Most of the transformers for distributing power are installed in the open air, and the insulating oil (transformer oil) is affected by

The influence of external impurities, contact with air, and higher operating temperature of the equipment itself causes the quality of the oil to gradually deteriorate.

Insulating oil (transformer oil) after deterioration will not play the role of insulation and cooling as it should. In order to prevent unsafe operation due to deterioration of oil quality, regular oil samples of distribution transformers in normal operation should be tested and analyzed, and the oil should be treated accordingly based on the analysis results.

The inspection period of the oil chemical supervision of distribution transformers in operation is stipulated to be at least once every 3 years. Routine inspection items include acid value, water-soluble acid, flash point, breakdown voltage, appearance, and dissolved gas.

• What's ZJA Series Transformer Oil Filtration Unit?

Our ZJA Series Transformer Oil Filtration Unit is mainly used for purifying and filtering ,filling, processing the product with hot oil circulation and directly unloading the oil from the oil drum for ≤500KV power transformers .
