750KV High Voltage Power Transformer Oil Purifier System Equipment,PLC Oil Purifying Machine
Application:
ZUD Series Ultra-High Voltage Transformer Oil Purification Machine is mainly used to improve the properties of insulation oil. It can remove trace water, gas, particulate matters etc. from the insulating oil effectively and rapidly so as to boost performance of transformers, circuit breakers, mutual inductors, cable and capacitors which has insulation system. ZUD series specialize in purifying branded oil, insulating oil of high voltage and super high voltage transformer.
Performance:
Re-refining to remove acids and particulate material
Dehydrating to remove free and dissolved water, including insulation dry-out of the windings.
Degassing to remove other dissolved combustible gases such as Acetylene, Ethylene, Ethane, Methane, Hydrogen and Carbon Monoxide, and Carbon Dioxide.

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.
