Transformer Oil Recycling Machine

Ⅰ. Transformer Oil Recycling Machine Usage

UHV Transformer oil filter is specially designed for 330kv-1000kv high voltage and above, UHV Transformer insulating oil purification. It is widely used in electrical equipment for transformer vacuum drying and vacuum oil injection. Compared with the two-stage vacuum oil filter, the UHV Transformer oil filter can increase the three-stage and above roots pump pressurization system, which can quickly dehydrate, degass and remove acetylene, making the acetylene value 0.

Ⅱ. Transformer Oil Recycling Machine Working Process

After impurity removal, dehydration, degassing and acid removal, the oil will pass through precision filter to complete a working cycle under the action of oil pump. The water vapor separated from the vacuum separation chamber enters the chiller, and most of the water vapor condenses into water and is stored in the water sump and discharged out of the machine. The purified oil returns to the prepared oil tank through the oil outlet.

Patent Automatic Vibration defoaming technology

infrared defoaming technology

×

most suppliers use this kind of technology for defoaming, actually the truth is they defoaming by make the air into the vacuum evaporation tank, the air with moisture and impurities, which will make the oil be polluted secondary.
If u like, i can send u this video, here i will give pics to show this, u see, when foam decrease, the vacuum decrease too, and here is a fabric, when defoam, it will be suctioned to the tank, which means here is air into the tank

Automatic Vibration defoaming technology
√

This is our patent technology in almost 10 years experience in transformer oil filtration. The design like bellow.
This is the core technology in vacuum oil purifier, at the bottom of the atomization chamber is equipped with a number of nozzles which are ejected downward. The the separation tower is connected with the elastic wire mesh and inner wall of the vacuum separation kettle tank. this can eliminated the bubble inside the vacuum tank, with the long time work, the electronic vacuum gauge measured value of -5Pa-133 Pa and no more foam rising

Ⅲ. Transformer Oil Recycling Machine Advantages

Adopts high Efficiency vacuum system , KAIQIAN own special vacuum separation technology , water, acetylene, acid value, mechanical impurities, free carbon and colloid removal efficient , to improve the pressure value of oil , increase the breakdown voltage , like :

The initial value of oil：water content：≤50mg/L、gas content：≤10 %(volume fraction)、breakdown voltage：≥25KV

After the third purification：residual moisture≤5-10ppm、residual gas：≤0.05%、acetylene content is zero、breakdown voltage ≥60KV(Spherical polar)

Note : water , gas measurement according to GB ,DL ,IEC standard .
