What is a transformer oil treatment machine?

A transformer oil treatment machine is specialized equipment used to purify and condition the insulating oil in transformers. This oil plays a crucial role in cooling and insulating transformer components, and over time, it can accumulate contaminants like water, gases, particulates, and acidic compounds that can degrade the transformer's performance. Transformer oil treatment machines remove these impurities, extending the life of both the oil and the transformer.

Here’s how a typical transformer oil treatment machine works:

1. Degassing: The machine removes dissolved gases, like oxygen and nitrogen, which can affect the insulating properties of the oil. This is done using a vacuum chamber that draws gases out of the oil under low pressure.

2. Dehydration: Water in the oil is a common issue, as moisture reduces insulation strength and accelerates aging. Treatment machines use heat and vacuum to evaporate and remove water content.

3. Filtration: Solid particles, such as dust, metal particles, or sludge, are filtered out. Machines often have multi-stage filtration systems capable of removing contaminants as small as 1 micron.

4. De-acidification: Some advanced machines can also neutralize acids formed in aging oil. Acid formation leads to corrosion and degradation of insulation.

Transformer oil treatment machines are commonly used in the maintenance and conditioning of oil-filled transformers, and they help maintain dielectric strength, reduce breakdown risk, and extend equipment life. Common brands include GlobeCore, Enervac, and Acore Filtration Co., offering models suitable for various transformer sizes and types.
