Standard performance and purification function of two-stage vacuum oil filter

The two-stage vacuum oil filter is higher than the national standard, the breakdown voltage of one filter can be increased by 35KV, and the damage of oil aging caused by repeated heating of general oil filter can be reduced. High vacuum, high pumping speed, pumping speed power ≥333L/s, to meet the installation or maintenance site of the transformer body vacuum requirements, and at the same time to complete the transformer oil degassing dehydration treatment. Nanomolecular material filtration and complex THREE-DIMENSIONAL flashing can remove water, gas and impurities in transformer oil and improve the compressive strength and quality of oil. Advanced infrared level control system, automatic control, man-machine separation operation. VK microgram technology can effectively remove the dissolved water and other trace water. It can realize the vacuum oil filling, vacuum drying and vacuum filtration of power transmission and transformation equipment above 110KV.

The two-stage vacuum oil filter is composed of vacuum heating tank fine filter, condenser, primary filter, water tank, vacuum pump, exhaust pump and electric gas tank. The vacuum pump draws out the air in the vacuum tank to form a vacuum. Under the action of atmospheric pressure, the external oil goes through the inlet pipeline into the primary filter to remove the larger particles and then into the heating tank. After heating, the oil of 40~75℃ passes through the automatic oil bleeder valve, which automatically controls the balance of the oil quantity entering the vacuum tank. After being heated, the oil is separated into a semi-mist by the rapid rotation of the jet wing. The water in the oil is rapidly evaporated into water vapor and continuously sucked into the condenser by the vacuum pump. Entering the condenser water vapor released back to the original after cooling water, in a vacuum heating oil tank, be drainage pump into the fine filter through particles in the filter paper or filter will filter out impurities, so as to complete the vacuum filters oil machine rapidly process to remove impurities in oil, water, gas, clean the oil from the oil discharge outside.

The double stage vacuum oil filter increases the regeneration and purification function of deteriorated oil. Before the vacuum filters oil machine is only a single remove impurities and moisture, the machine increases the net silicone oil system, and the net silicone oil and impurities filtration one, for mild metamorphism of transformer oil filter out impurities, adsorption regeneration after silicone oil purifier, oil to the qualified standard. To improve the design of the original oil and gas separator. By using vacuum oil inlet, the tubular rotary injector is installed, which reduces the resistance, accelerates the rotation speed, and increases the separation effect of oil and gas. This machine can be used for all kinds of oil-immersed transformers, oil-immersed current and voltage transformers and high-voltage oil-less circuit breakers.
