How to Conduct Effective Transformer Oil Degassing and Treatment?

Transformer oil degassing and treatment are essential processes for ensuring the proper functioning and longevity of transformers. Over time, the oil inside transformers can become contaminated with gases, moisture, and solid particles, all of which can reduce the oil’s insulating and cooling properties. This contamination can lead to overheating, reduced efficiency, and even transformer failure if left unaddressed.

In this article, we’ll dive into the importance of transformer oil degassing and treatment, the machines used for the process, and why these steps are crucial for your business’s operations.

What is Transformer Oil Degassing?

Transformer oil degassing is the process of removing unwanted gases, like air and moisture, that become trapped in transformer oil during operation. As transformers heat up and cool down, gases can dissolve into the oil, which reduces its ability to insulate and cool the system properly. These dissolved gases, including oxygen and nitrogen, can also cause internal pressure to build up, potentially leading to transformer malfunction or failure.

Degassing typically involves using a vacuum treatment system to lower the pressure inside the oil, which causes the gases to separate from the oil and escape. The process may also include heating the oil to help speed up the release of these gases, ensuring the oil is restored to its optimal condition for insulating and cooling.

The Importance of Transformer Oil Treatment

Proper transformer oil treatment is essential for several reasons, all of which contribute to the longevity and efficient performance of your transformers:

Enhanced Insulation: Over time, moisture and gases in the oil can reduce its ability to insulate. This can lead to transformer faults or breakdowns. By treating the oil, you remove these contaminants, ensuring the oil retains its insulating properties and helps prevent electrical failures.
Extended Transformer Life: Contaminants like water and sludge in the oil can cause premature wear on the transformer components. Regular oil treatment helps protect the internal parts of the transformer, slowing down the aging process and extending its operational life.
Improved Cooling Efficiency: Transformer oil helps regulate temperature by dissipating heat. If the oil is contaminated, it loses its ability to cool the transformer efficiently. Oil treatment restores the oil’s cooling capabilities, helping prevent overheating and improving overall performance.

By maintaining high-quality oil, you ensure that transformers run at their best, minimizing risk, preventing costly repairs, and improving the overall reliability of your electrical system.

Use Transformer Oil Treatment Machines for the Process

To effectively treat transformer oil, specialized machines are essential. These machines are designed to remove contaminants like moisture, gases, and particulate matter, ensuring the oil remains in top condition for optimal transformer performance.

Vacuum Oil Purifiers

Vacuum oil purifiers are among the most commonly used machines for transformer oil treatment. These units utilize a vacuum to lower the pressure inside the transformer oil, which causes dissolved gases and moisture to separate from the oil. The oil is typically heated to further enhance the degassing and dehydration process. The machine operates by creating a low-pressure environment, which allows dissolved gases and moisture to rise to the surface of the oil. The oil is then passed through a vacuum chamber where the contaminants are removed.

Effective Removal of Gases: It efficiently removes gases like oxygen, nitrogen, and carbon dioxide, which can degrade the insulating properties of the oil.
Dehydration: The vacuum also helps in removing moisture, which can cause the oil to lose its dielectric strength and cooling ability.
Energy Efficiency: This method is energy-efficient since it requires less heat than traditional methods to separate gases and water.

Ideal for treating oil in transformers, especially when the oil has absorbed moisture from the surrounding environment or has accumulated dissolved gases during transformer operation.

Oil Filtration Units

Oil filtration units are specifically designed to remove solid contaminants such as sludge, carbon, dirt, and other particulates from transformer oil. By improving the cleanliness of the oil, these units directly enhance the performance and longevity of the transformer.

The oil flows through a series of filters that capture solid particles, with some units pre-heating the oil to reduce viscosity and improve filtration efficiency. Additionally, certain machines utilize centrifugal or mechanical filtration methods to remove particulate matter effectively.

Removal of Solid Contaminants: The primary function is to eliminate any solid impurities that could damage the transformer’s internal components.
Enhanced Oil Quality: By cleaning the oil, these units restore its dielectric strength and improve overall efficiency, helping the transformer operate at peak performance.
Prevention of Sludge Build-up: Regular filtration helps prevent sludge accumulation, which can otherwise compromise the oil’s cooling and insulating capabilities.

These units are ideal for oils that have been in service for extended periods and accumulated contaminants, especially in transformers operating in dusty or challenging environments.

Dehydration and Degassing Units

Dehydration and degassing units combine both moisture removal and gas separation processes to ensure transformer oil is as pure as possible. These machines are typically used when the oil has been exposed to large amounts of moisture or has absorbed significant levels of dissolved gases. These units use a combination of heating and vacuum systems to remove both water and gases from the oil simultaneously.

Moisture Removal: These units are highly effective at extracting water that has been absorbed by the oil, preventing it from causing corrosion or reducing the oil’s insulating properties.
Gas Separation: In addition to moisture, the vacuum system helps to separate dissolved gases, such as oxygen and nitrogen, from the oil.
Efficient Process: The combined effect of heat and vacuum accelerates the dehydration and degassing process, improving the oil’s overall quality.
Restoration of Oil Properties: By removing both moisture and gases, these units help restore the oil’s dielectric strength and cooling ability, ensuring that the transformer operates at peak performance.

Dehydration and degassing units are ideal for transformers that have been exposed to severe contamination, ensuring the oil is both dry and gas-free for optimal functioning.

Need to Invest in a Transformer Oil Treatment Machine?

If your business operates transformers, investing in a transformer oil treatment machine can significantly improve the efficiency and longevity of your equipment. Here are a few factors to consider when deciding whether it’s time to invest in one:

Frequency of Transformer Maintenance: If your transformers require regular oil treatment due to frequent operation or harsh conditions, having your own treatment machine can streamline the maintenance process and reduce downtime. By owning a machine, you can perform oil treatment on demand and avoid delays caused by relying on external services.
Improved Operational Efficiency: With a treatment machine, you can ensure that your transformer oil remains free from contaminants, moisture, and gases. This improves the overall performance of your transformers, helping them run more efficiently and reducing the risk of overheating or electrical malfunctions.
Long-Term Cost Savings: While the initial cost of purchasing an oil treatment machine may seem high, it can be a wise investment in the long run. Transformer oil treatment machines help prevent costly repairs and transformer failures, reducing the need for expensive replacements or emergency maintenance. By keeping your transformers in optimal condition, you can avoid unexpected costs and extend the lifespan of your equipment.
