Advanced Technology Multi Stage Transformer Oil Purification System/oil Purifier Machine
advanced technology multi stage transformer oil purification system/oil purifier machine
ASSEN ZYD transformer oil purification system can remove water and gas in the insulating oil under high temperature and vacuity. it use more precise filter system to filter out impurities(filtering precision: 1-3um). It ia mainly used for purification of oil for transformer with voltage higher than 220kv. It can increase oil breakdown voltage by at least 40kv.They are suitable for oil treatment, vacuum oil injection, and cylic hot-oil drying in the installation and maintenance of big transformers.
1.To remove free, soluble water, carbon, free and dissolved gases and particulate matters from insulating oil effectively and rapidly.
2.Enhance the value of breakdown voltage greatly.
3.Easy handling and maintenance.
4.Inject oil into the transformers
5.Online work
6.Lower maintenance and replacement expenses
7.High efficiency and effectiveness
8.Available in mobile or stationary options.
9.Small size, light weight, low noise
10. Various sizes and configurations (alloy shield) available.
Series ZYD transformer oil purification system 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.

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 Purification System'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.
