Transformer oil filtration machine to increase and maintain the oil's dielectric strength, Vacuum Dehydration Machine

I. Application of Transformer Oil Filtration Machine

Transformers require filtered and dried oil. The efficiency of the oil as an insulating material is highly reduced as the moisture level increases. Hence, transformer oil filtering is an important process.

Transformer oil filtration is carried out with Ultra High Vacuum oil filter machine of adequate capacity. Our mobile oil filtration plant is designed to remove dissolved moisture, dirt, air and other gases from the transformer oil.

This Double two-stage Vacuum Mobile filtration plant operates on the principle of Low Temperature and High Vacuum. Especially suits for above 350KV power transformers. With a higher extreme vacuum to achieve a better dehydration and degassification.

II. Working Process of Transformer Oil Filtration Machine

1. Unfiltered oil is taken in to the system through the inlet valve.

2. Then the oil is sucked to the system by means of pressure difference.

3. Preliminary Coarse filters can remove solid and magnetic particles up to 50 μm size.

4. The oil is heated up to 60-65°C. After heating the oil flows into a specially designed vacuum chamber, where the moisture, air and other gases are extracted from the oil. The vacuum chamber is designed in such a way that the oil is spread out and is allowed to fall by gravity over the media inside, forming a thin film of oil providing a large surface area exposed to vacuum. With this exposure, the dissolved moisture and gases are evacuated to improve the insulating properties of transformer oil.

5. Then the oil is pumped by an outlet pump and passes through the fine filters where the particles up to 1 microns are filtered.
