Vacuum Transformer Oil Purification Plant
Vacuum Transformer Oil Purification Plant – Acore Filtration Co.Ltd October 11,2017.


To meet the needs of the power maintenance department on-site maintenance of various types of high and low voltage oil equipment, we developed a small size Transformer Oil Purification Plant with proportion of light weight, easy to move, low noise, continuous working time, stable performance, easy operation. It is the ideal Oil Purification Plant for removing water, gas and impurities from insulating oils.


1. All kinds of oil-immersed transformers, oil-immersed current, voltage transformer and less oil relay, the scene of oil and fuel.

2. The above-mentioned equipment on-site hot oil circulation drying, especially for oil-immersed current, voltage transformer and less oil circuit breaker hot oil circulation is more effective.

3. Sealed oil immersion equipment for on-site vacuum filling and transformer vacuum pumping.

4. Mild deterioration of the transformer oil to purify, to achieve the performance of qualified oil standards.


1. Small size, light weight and easy to move

2. Improving the performance of oil and gas separation..

3. Filter elements of transformer oil purification plant: non-toxic and tasteless felt made of tubular filter, filter bag large amount of pollution and high precision.

4, can be used in the field, and the use of the original oil equipment to do storage tanks, so that the hot oil circulation between the machine and equipment, so that the oil filter, hot oil drying at the same time.

Working Principle

The Vacuum Transformer Oil Purification Plant is designed according to the different boiling points of water and oil. It consists of vacuum heating tank, fine filter, condenser, primary filter, vacuum pump, oil pump and electric cabinet. Vacuum pump will be vacuum out of the vacuum tank to form a vacuum, the external oil under the action of atmospheric pressure, the oil through the inlet pipe into the filter to eliminate the larger particles, and then into the heating tank, after heating to 40-75 ℃ oil through Automatic oil level valve, the valve is automatically controlled into the vacuum tank into the oil balance. After the heating of the oil through the rapid rotation of the wing of the oil will be separated into a half mist, the oil quickly evaporate into water vapor and vacuum pump into the condenser, into the condenser water vapor after cooling and then back The original water release. In the vacuum heating tank of oil, the oil pump discharged into the fine filter through the filter element will filter out the impurities. So as to complete the vacuum oil filter quickly remove the oil impurities, water, gas the whole process, so that clean oil from the exit at the machine outside the machine.


Connected to the tubing, according to the size of the total power of the Transformer Oil Purification Plant connected to the three-phase four-wire power supply, and the vacuum pump, pump steering and arrow pointing to the same, connected to a safe ground, check whether the circuit is connected to the oil valve is open , Jog vacuum pump, oil pump should be no jamming and eccentric vibration phenomenon. Condenser models can be through the drain valve to the storage room into the tap water, ready to proceed after the operation procedures. First, close the circuit breaker, turn on the power off button, press the vacuum pump button, when the vacuum surface reaches 0.08MPa negative pressure, you can open the oil into the oil valve, when the vacuum tank oil reaches the midline of the oil position (avoid The oil is sucked into the vacuum pump, otherwise the equipment can’t run normally. If the oil is inadvertently sucked into the vacuum pump, the oil should be released from the vacuum pump and then the appropriate vacuum oil should be added. So that the normal operation of the oil circuit, the normal operation, observe the oil pipe to adjust the inlet valve to keep the oil balance, press the heater open button, according to the vacuum and water saturation curve set the heating oil temperature to oil heating (upper The oil temperature is lower, the upper limit should be greater than the lower limit of the temperature 5 ~ 10 ℃) Valve control to adapt to the vacuum, to be reduced water, oil off after the release valve, so that the vacuum reaches the limit. At this point should pay attention to the reaction of the instrument, if the pressure gauge reading is greater than 0.4MPa, indicating fine filter inside the filter surface adsorption of impurities too much need to be cleaned, after work, stop the first press the heater button, wait 3 Minute, then press the vacuum pump button, close the oil inlet valve, wait for the oil tank after the tank row after pressing the oil pump button, open the vent valve to the vacuum to normal atmospheric pressure, the remaining oil from the oil discharge valve to prevent The next time mixed with different types of oil, and finally pull down the circuit breaker.
