In order to achieve optimal dielectric strength and insulating performance inside of transformers and circuit breakers, dielectric oils must be kept absolutely clean and dry. ZHONGNENG designs and builds the most effective, durable, and easily operation high vacuum transformer oil purification system on the market today.
Transformer oil filtration system means?
Old transformer oil is generally mixed with gas, water and contaminants, and also the new transformer oil sometimes, the content of the contaminants generally increases fast by time. So the transformer oil treatment machines can remove these associated gases, water and contaminants, and separate them from the oil and take them away. After treating the oil by our oil treatment plant, the stabilized oil is then again ready to be used in power transformers.
Series ZYD Double-stage transformer oil filtration system can quickly remove water, trace water, gas, particles as well as acetylene, hydrogen, methane and other harmful ingredients from oil effectively to improve oil’s dielectric strength, effectively making sure electric equipments working safely and normally. Series ZYD oil purifier is particularly suitable for treating high-grade transformer oil, super-voltage transformer oil and new transformer oil. It can be used for filtration of more than 110V substation live line work onsite. Meanwhile, Series ZYD oil purifier can be used as independent vacuum source with functions of vacuum drying and vacuum oiling.
The series ZYD Double-stage vacuum Transformer oil filtration system is designed for the following application:
I. Degassing, dehydration and filtering impurities of transformer oil
II. Remove acidity, sludge, free carbon, other soluble oil decay products and discoloration
III. It can vacuum filling oil to transformer, vacuum dry transformer and on-line operation transformer .
IV. It is mainly used for purifying the insulating oil, transformer oil, mutual oil, switch oil, dielectric oil and so on. The standard ZYD system is designed for processing oils in workshops, in storage tanks or directly in transformers (energized or de-energized transformers).
1.Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.
2. Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies
3. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
4. Double-infrared liquid level sensor, pressure protective system to ensure the machine operation easy and safely.
5. Adopts 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. Working with BZ insulating oil regeneration device to decolor (remove acid, oxide, free carbon) and lower dielectric loss, making the treated oil more limpidity.mining enterprises purifying the unqualified transformer oil, mutual inductor oil, switch oil and so on.
The oil technical data after treatment:
1. Gas content less than 0.1%
2. Impurity size less than 1μm without free carbon
3. Oil dielectric strength (breakdown voltage) more than 75KV
4. Acidity value less than 0.01 mgKOH/g
5. Dielectric loss factors at 90℃ less than 0.001
