Multi stage vacuum transformer oil filtering equipment,HV oil filtration plant

ZYD Multi stage vacuum transformer oil filtering equipment is mainly used to extend the lifetime of oils used in transformers, circuit breakers, mutual inductor, voltage regulators and switch gear, or to inject the insulating oil into the transformers. Equipped with regenerators, ASSEN transformer oil filtering equipments can improve the effect of de-acid, de-color and remove dielectric and acid more effectively. The value of breakdown voltage will increase from 15KV to 75KV. The performance and lifetime of insulating oil will improve and extend awfully after purification and regeneration.

1. Unique and highly efficient dewatering and degassing device, it adopted a large area three-dimensional flash evaporation and mature film evaporation technology to rapidly remove the free and dissolved water and gases from used and waste insulating oils. 
2. Precise filtration system, high quality filter element, multi-stage filtration system levels, can effectively remove the mechanical impurities from the insulating oils. 
3. Electrical heating system is the optimized pipeline design to ensure uniform heating and stable oil temperature. 
4. Automatic constant temperature control device, automatic liquid level control device, automatic defoaming device, automatic pressure protection device and excellent configuration can ensure the equipments in high performance. 
5. Work online and the indicators display running. 
6. Unattended operation with low working noise and longtime free maintenance.
7. A complete machine safety interlock protection system, discharge oil system, vacuum system and the heating system interlock, to avoid the adverse effects of misuse. 

Oil filtering equipment's Technical Data:

Structure Chart:
 

The oil technical data after treatment:

• Gas content less than 0.1%
• Impurity size less than 1μm without free carbon
• Oil dielectric strength (breakdown voltage) more than 75KV
• Acidity value less than 0.01 mgKOH/g
• Dielectric loss factors at 90°C less than 0.001

Oil filtering equipment's Advantage:

Good vacuum pressure and high flow rate. This product makes bridge with the electric equipments. Vacuum, filtration and oil injection can work independently and also they can work together. As the oil purifying nanotechnology, this machine can treat oil more quickly and more completely, and makes the oil limiting voltage-withstand value much higher than the ordinary vacuum oil purifier

Q: How can we achieve drying without elevated heating of the insulation material for transformers?
A: Drying of insulation materials can be achieved at low temperature and low pressure levels. The pressure levels and temperature levels for drying vary for distinct material. At low pressure or under vacuum the rate of water vapour evaporation is accelerated if sufficient heat is provided to the insulation material. Thus we can achieve a good drying of insulating material if the material is suitably heated and subjected to vacuum.
