Chongqing Assen Power Equipment Co.,LTD

Application: Moisture is one of the most important contaminants that affect the performance of the dielectric fluid and ultimately affect the life of the transformer. ASSEN ZYD high efficiency transformer insulating oil purification unit combines unique advanced vacuum dehydration, degassing components and three-stage filtration system to quickly and efficiently separate water, gas, particles and oil to restore the performance of insulating oil. 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 the 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. Functions: 1. Dehydration, degassing and impurity removal of 110-1100KV main transformer insulation oil . 2. Acetylene removal of 110-1100KV main transformer insulation oil . 3. Vacuum drying of 110-1100KV main transformer insulation oil . 4. It can remove not only 100% free water and 99.9% dissolve water, but also 100% free gas and 98% dissolve gas. 5. Customized parts: PLC, frequency conversion technology, trailer and so on. 6. Advantages and characteristics The oil’s performance after treatment: Moisture PPM ≤3 Gas content % ≤0.01 Impurity size μ ≤1 (no free carbon) Breakdown voltage kV ≥75 IFT dynes/cm ≥40 Acid value mgKOH/g ≤0.03 Dielectric loss factors tgδ(90°C) ≤0.001 Please contact us for more details.
