ZYD type transformer oil purification,oil water removal equipment

ZYD series vacuum transformer oil purification 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 purification 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. Pre-Electromagnetic-valve before vacuum pump to prevent the vacuum oil flow backwards.

2. Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value ≤ 5Pa

3. Two vacuum separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.

4. Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.

5.Adopt interlocked protective system, which connect oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping, oil leak and electricity leak. If there is any fault, machine will be power off automatically.

6. Pre-gas-water separator before vacuum pump to prolong the vacuum pump and vacuum pump oil.

7. Double protecting system, Gas-water separator equips liquid level protector to prevent oil escape from vacuum pump

8. Optical oil foam detector and high oil level detector to prevent oil escape from vacuum pump

9. Low oil level sensor to prevent oil pump idle working, so prolong oil pump lifetime

10. Completely Intelligent pressure protector to protect oil pump and fine filter

11. Completely Intelligent vacuum controller to protect the booster pump

12. Fully intelligent temperature controller to prevent the large surge current

13. Phases protector, voltage overload protector to achieve unattended

Series ZYD oil water removal equipment is suitable for filtering new oil ,imported oil and super HV transformer oil, particularly applicable to 110KV power distribution system and the national grid, shortening the oil treating duration during installation and maintenance of transformer.

oil water removal equipment'sTechnical 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 water removal equipment's Advantage:

Comparing with the single-stage type, this machine adopts the double stages vacuum system, which can improve the machines working vacuum value highly, so it can dewater, degas and remove the impurity more deeply and effectively. The dielectric value of treated oil is higher than 75 KV. It is very suitable for the large electric & insulation equipments.

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.
