ZJB Single Stage Vacuum Transformer Oil Filtration Plant
For small transformers, ZJB single-stage vacuum oil purifier plant is specially designed to remove pollutants, such as particles, water, gas, etc.
Dissolved gases in transformer oil can cause arcing, corona discharge, and overheating, reducing the electrical efficiency and life of the transformer. Similarly, water pollution down to 30 ppm (parts per million) can adversely affect the insulation strength of oil. With the continuous improvement of energy efficiency standards for distribution transformers, the need for effective degassing will become increasingly important in the future. Particle contamination can also affect the function of the insulating oil.
ZJB Single Stage Vacuum Transformer Oil Filtration Plant (Oil Purifier) is specially designed for oil filtration, drying, and degassing of insulating oil. This type of vacuum purification treatment is widely used and it gives out more economical benefits to increase and maintain insulating properties. Transformer oil filtering is not just suited for sullied or polluted oil, even new insulating oil is in need of filtration, because it is not enough clean to be used in high-voltage electric equipment, as it can also be polluted during transportation tanks and might get ‘invaded’ by moisture or dust, so this new oil also needs purification before filling into transformers.

Features of The Single Stage Vacuum Transformer Oil Filtration Plant
1. Improves the dielectric strength of the oil by effectively removing solid particles, gas, and water, thus eliminating the need for expensive oil replacement, thereby extending the life of electrical equipment.
2. The system is operated and monitored through the control panel
3. The specially designed degassing tank system makes the treated oil evenly distributed in the low-pressure environment to achieve the best treatment effect.
4. Digital electric heating system and safety thermostat, designed to allow temperature range of 20-80°C.
Working Principle of Transformer Oil Filtration Plant
To purify oil under the action of negative pressure from the oil inlet valve into the primary filter to filter out the larger particles of impurities, heating the oil by the heater to the set temperature(controlled by the automatic constant temperature digital display temperature controller).
The heated oil into the vacuum chamber and be atomized by the atomized spray, step by step in the efficient separation tower from the developed area a great deal of oil film.
Under the vacuum rapid evaporation realizes the separation of oil, water, and gas.
The isolated oil by a special oil transfer pump pumping out and go to the fine filter to remove the mechanical particles for completing a purification cycle.
Depending on the crude oil condition, one to three times oil purification circulation can achieve the requirement.
Working Flow of the Vacuum Transformer Oil Filtration Plant
To be treated oil storage equipment → Oil inlet → Oil inlet valve → Primary filter → Solenoid valve → Heater → Vacuum separation chamber → (two ways):
- → Vapor → Condenser → Vacuum pump PV4.1 → Air
- → Clean Oil → 1st stage Atomizer → 1st stage separation tower → Oil outlet pump → Fine filter → Oil outlet valve → Oil outlet → To be treated oil storage equipment
