Application
ASSEN ZYD High Vacuum Transformer Oil Filtration machine was designed according to decompression separation, precise filtration, Spiral spray atomization separation technology, molecular adsorption, vacuum drying principle. The treated oil can meet the standard of the national standard.
Advantages:
1 Enhance the value of breakdown voltage of oil greatly.
2 Easy handling and maintenance. It is available that online work. The plant can provide the ability to inject oil into the transformers without an extra accessory.
3 Lower maintenance and replacement expenses.
4 High efficiency and effectiveness while small size, lightweight, and low noise.
Flow Chart:
The oil to be treated passes through a strainer and enters the heater for heating, the heated oil will go through the semi-precision filtration and arrived at the Spiral spray atomization separation system, The insulating oil turns into a coarse mist and falls onto the reaction tower to enter the vacuum separation chamber. The moisture begins to evaporate and the oil mist forms a three-dimensional, multi-layer evaporation structure in the tank, which can be purified through a short-term cycle. After dewater, degas, and impurity, acid removal, the treated oil will go through precision filtration to achieved the purifier circulation purpose. The Water vapor molecules and the hot air are separate from the vacuum separation chamber enters the condenser , most of the water vapor is condensed into water and stored in a water tank. The hot air in the oil is cooled and discharged by a vacuum pump.
Transformer Oil Dehydration Machine's Technical Features:
1.Advanced dehydrating and degassing system that uses large-area three-dimensional flash distillation technique to remove harmful composition in the oil such as water, air, and gas.
2. It can be widely used for oil filling for transformers and circuit breakers under vacuum conditions.
3. Precise filtration system, high-quality filter element, multi-stage filtration with gradual precision can help to remove mechanical impurities in the oil.
4. An advanced fully automatic temperature controlling system,liquid-level controlling system, defoaming controlling system, pressure protecting system, and excellent configuration can ensure operation of the equipment with high performance.
5. Online work, allowing separated operation of manual operators from the machine with lamps indicating the condition for operation.
6. It is a humanization design with low noise, deep purification, and long-time free maintenance to save cost from the running process.
7. Purifiers are equipped with a chain safety protective system, an interlocking oil drainage system, a vacuum system, and a heating system, which avoids any possible negative impacts caused by mal-operation.
After treatment, oil quality guarantees the following specifications.
| Moisture | PPM | ≤3 |
