How Vacuum Oil Purifiers Enhance Transformer Oil Performance

Transformer oil is essential for the proper operation of electrical transformers. It helps in insulation, maintaining the integrity of windings, and suppressing arcs as well as electrical discharges. However, moisture in transformer oil compromises insulation and arc suppression, cooling transformer functions, and efficiency. Therefore, the traditional method of selling used oil without adequate dehydration is not only inefficient but also adds unnecessary costs. This problem is solved by developing a transformer oil dehydration machine with advanced techniques in dehydration and degassing. This article describes the importance of vacuum oil purifiers and their impact on the performance of transformer oil.

What Is a Transformer Oil Dehydration Machine?

The transformer oil dehydration machine is specifically designed to address the dehydration and degassing requirements of transformer oil. It employs a three-dimensional rapid evaporation system and pressure reduction separation technology to achieve efficient dehydration. By creating a high vacuum environment, this purifier enables rapid evaporation of water without compromising the integrity of oil additives through excessive heating. The use of a double-stage vacuum process enhances the withstand voltage of the treated oil, resulting in improved performance and longevity.

Functions of Vacuum Oil Purifiers

A vacuum oil purifier is used for extracting contaminants from transformer oil to maintain optimal performance. The machine has a filtration efficiency that removes both separated and dissolved water as well as separated and dissolved gases. The efficiency of the vacuum oil purifier is exceptional, removing 100% of free water and up to 99.9% of dissolved water. The purifier eliminates 100% of free gas and 98% of dissolved gas. These processes enhance the insulation properties of the transformer oil, which improves the reliability of the operation and reduces the chances of electrical breakdown.

In addition, the transformer oil dehydration machine performs functions other than dehydration and degassing. It has applications in oil filtration, which enhances the quality and purity of the treated oil further. Moreover, the purifier has vacuum drying as well as oil injection functions, and so can fill and dry transformer equipment under vacuum. This all-inclusive approach enhances the performance of the oil and equipment while extending their service life.

Advantages of Vacuum Oil Purifiers

By utilizing a vacuum oil purifier, several advantages can be achieved. Firstly, it eliminates the need to sell used oil as a waste product, thereby reducing resource waste. Instead of the traditional practice of discarding used oil and purchasing new oil, the purifier allows for the reclamation and reuse of treated oil, resulting in cost savings and environmental sustainability.

Secondly, vacuum oil purification ensures that the transformer oil maintains its optimal performance characteristics. By removing moisture and gases, the oil’s insulating and arc suppression capabilities are restored, enabling efficient cooling and preventing electrical discharges. This, in turn, safeguards the integrity of windings and enhances the overall reliability of the transformer system.

Conclusion

The proper functioning of transformer oil continues to require supervision, and thus, the usage of oil purifiers, such as the transformer oil dehydrator, has proven to be effective. These vacuums enhance the oil’s insulation properties, preventing electrical breakdowns, absorbing water, and removing gases from the oil. The maintenance of used vacuum oil enables oil to be reused rather than sold, resulting in less waste. The preservation of transformer systems greatly depends on the dedication provided when maintaining the oil; therefore, these systems must be treated with vacuum oil purifiers. With the enhancement of these oil maintenance technologies, the power sector translates to optimized reliability and sustainability in the operational demands of the transformer systems.
