Application | Fully Automatic Transformer Oil Filtration System For Power Plants

In the heart of every power transformer lies its lifeblood: transformer oil. This vital fluid serves as a robust insulator and an efficient coolant, ensuring the stability and longevity of the very equipment that powers our cities, industries, and homes. But like any lifeblood, it is vulnerable. Moisture, particulate matter, and dissolved gases are the silent adversaries that degrade its performance, threatening catastrophic failure and immense operational costs.

The High Cost of Contamination: More Than Just Dirty Oil
Before delving into the solution, it's crucial to understand the stakes. Contaminated oil isn't merely a maintenance issue; it's a significant business risk.

• Reduced Dielectric Strength: Moisture and particles compromise the oil's insulating properties, increasing the risk of internal arcing and transformer breakdown.
• Accelerated Aging: Oxidation, catalyzed by heat and moisture, breaks down the oil, forming sludge that coats windings and impairs heat dissipation. This forces the transformer to work harder, shortening its operational life by decades.
• Component Corrosion: Acidic byproducts of oil degradation corrode critical internal components, leading to costly repairs or replacements.

The PureTech Fully Automatic Transformer Oil Filtration System is designed to remove moisture and particles which compromise the oil's insulating properties, increasing the risk of internal arcing and transformer breakdown. And therefore, extend the lifespan of transformer oil, save money for the maintenance work.

Features | Fully Automatic Transformer Oil Filtration System For Power Plants

• Elimination of residual gas from the insulation by ultizing multi-stage filters of large dirt-holding capacity

• Drying of transformer insulation includes insulation paper drying (with double stage vacuum pump system)

• On-line measuring and recording of process parameters

• Easy, intelligent and safe operation

• Flexibility in application - various oil types and oil volumes (variable speed is optional if user required)

Process in short | Fully Automatic Transformer Oil Filtration System For Power Plants

1. Filtration: Adopts one built-in filters to protect the oil purification plant against coarse contamination. And  two stages of fine filters to control the pollution level by removing 99.9% of the impurities over 5 (or 1) microns, and to achieve the final cleanliness of transformer oil.

2. Oil Heating: the aged transformer oil is heated by electrical heater with thermostat, which can brought the oil to the required heating temperature but avoid of overheating or dry burning. The specially designed horizontal heating tubes and generously dimensioned heating surface lower the heating density and lower the aging of transformer oil.

3. Degassing System:  this is where oil dehydration and oil degassing happens. This degassing system has been optimised and expanded with an automatic foam control. It has greatly expands the exposure surface of moisture under the vacuum, therefore greatly improve the efficiency of Transformer Oil Dehydration and degassing.

4. Vacuum Pump system:  it adopts a Single(Model VOP)/double-stage(Model DVOP) high vacuum pump system, used for evacuation of gases and create a vacuum for the degassing system. While it is not working for oil dehydration, it can be used standalone, as a separate vacuum pump system for transformer evacuation, to dry transformers and the insulation paper.

5. Oil transfer: the whole plant equipped oil pump to convery the transformer oil to different stages by means of differential pressure. It  can be optionally added frequency inverter to allow variable flow rates.

6. Other online measuring instruments and accessories: this oil purification plant can be included in some built-in measuring instruments and accessories, for example, built-in moisture content tester to check the real-time ppm value of transformer oil,  trailer-mounted type with water-proofing cover to protect the plant from harm of extreme weather or strong sunshine outdoor, etc.
