High Vacuum Dewatering Transformer Oil Purifier Stationary Type

Application of Sino-NSH VFD-50

It is mainly used for large-scale transmission and transformation equipment above 110KV and the national main transformer grid, on-site maintenance of transformers in large-scale substations, rapid and advanced treatment of new oil, imported oil, and other insulating oils, new oil, imported oil, transformer oil and substation systems Vacuum filtration and purification treatment of relatively expensive oils such as capacitor oil and refrigerating machine oil.

Double-stage Transformer Oil Vacuum Purifier Features

1. The various indicators of the product are much higher than the international standard. Compared with the single-stage vacuum oil filter, its dehydration, degassing, and impurity removal (mechanical impurities and free carbon) are faster and more thorough. The point is higher, and the breakdown voltage after treatment can be increased to better than 75kV.
2. The double-stage vacuum with a high pumping rate can greatly improve the vacuum environment in the tank to achieve a high vacuum, the ultimate vacuum is ≤5 Pa and the working vacuum is ≤35 Pa so that the oil temperature remains unchanged during the treatment process and meets the requirements of the installation. Or the need for vacuuming the transformer body at the maintenance site greatly shortens the oil treatment period.
3. Unique degassing and dehydration system, compound three-dimensional flash evaporation, can quickly remove liquid water, can effectively remove trace moisture such as dissolved water, and efficiently complete degassing, dehydration, and treatment of transformer oil to improve oil quality, and dielectric strength.

Why should the oil filtration machine be adopted?

After the transformer has been used for a long time, there are gas, moisture, and other impurities will be in the dielectric insulating oil due to the pressure. These factors affect the insulation function and heat dissipation properties of the transformer oil. Therefore, transformer oil filtering must be adopted.

Advantages

1. Double-stage vacuum with large pumping speed and advanced dehydration and degassing system adopts large-area three-dimensional flash evaporation technology, which can quickly and efficiently remove moisture, impurities, hydrocarbons, and other harmful components in the oil, and improve the flash point and Dielectric strength.
2. It can meet the needs of vacuuming and vacuum oiling the transformer body at the installation or maintenance site.
3. A sophisticated filtration system, high-quality filter element, and multi-stage filtration step-by-step encryption can effectively remove mechanical impurities in the oil.
4. Advanced automatic constant temperature control system, automatic liquid level control system, automatic defoaming control system, automatic pressure protection system, and sophisticated configuration ensure high-performance operation of the equipment.
5. Highly automatic, can be unattended, and the operating status is displayed by the indicator light.
6. The machine has humanized design, low noise, simple operation, long maintenance interval, low energy consumption, and low operating cost.
7. The whole machine is equipped with interlocking safety protection, and the oil discharge system, vacuum system, and heating system are interlocked to avoid adverse effects caused by misoperation.
8. Equipped with leakage and overload shutdown devices to protect the motor.
