Chongqing Rexon Oil Purification Co., Ltd

Transformer oil filter Transformer oil filter is a mechanical device that filters solid impurities and moisture in oil, improves oil quality and improves the insulation strength of transformer oil. It is applied to power plant, power station, electric power company, metallurgy, petrochemical, railway and other industrial and mining enterprises to purify and dispose of unqualified electrical insulating oil. It can also vacuum inject insulated power equipment and vacuum dry electrical equipment. working principle When the oil filter is working, the oil enters the primary filter through the inlet under the action of the pressure difference between the inside and the outside, and the large particle impurities are filtered out. After the oil is heated by the multi-stage infrared, it enters the special personalized vacuum separator and is separated in the vacuum. The mist is formed in the first shape, and then formed into a film shape, so that the contact area in the vacuum is expanded by hundreds of times. The moisture in the oil is rapidly obtained under the conditions of high heat, high vacuum, large surface and high pumping speed. It is vaporized and discharged by a vacuum system. The water vapor discharged from the upper part of the vacuum separator is first cooled and dehumidified by the condenser, then cooled into the cooler, and the condensed water is discharged into the water storage device, and the gas after being condensed and dehumidified twice is finally discharged into the air by the vacuum pump. The dry oil after vacuum dehydration in the vacuum separator is raised from the negative pressure to the positive pressure by the oil pump, and after filtering, the clean oil is discharged from the oil outlet to complete the entire oil purification process. classification Transformer oil filter is mainly divided into two types: ordinary vacuum oil filter and two-stage high efficiency vacuum oil filter. The transformer oil filter can quickly remove harmful components such as moisture, gas and impurities in the transformer oil, improve the lubricating performance of the transformer oil, and reduce the corrosion or corrosion of the transformer oil due to excessive moisture or impurities. To extend the service life of oil equipment. Characteristics Ordinary transformer oil vacuum oil filter features: It is used in power plants, power stations, power companies, metallurgy, petrochemical, railway and other industrial and mining enterprises to clean and dispose of unqualified electrical insulating oil. It can also vacuum inject insulated power equipment and vacuum dry electrical equipment. 1. Three-dimensional flashing, efficient dehydration and degassing. 2. The impurity removal technology combined with mesh filtration and polymer adsorption. 3. Infrared level automatic control. 4. Trinity interlocking and protection device. 5. This unit can be used independently or in combination with an oil regeneration system. 6. This machine can vacuum-insert the insulated power equipment such as transformers and vacuum dry. 7. Randomly detect the withstand voltage value and automatically print the test result (generally the purchase option). 8. This machine can be used together with the transformer oil regeneration decoloring device to increase the functions of acid removal, decolorization, free carbon removal and dielectric loss reduction (commonly known as multi-function insulating oil filter). 9. This machine has both vacuum oiling and live online operation. This machine has a three-in-one interlocking electrical automatic protection device (phase sequence protection, overload protection, over-voltage protection), using the company's special precision oil pump, low noise, in line with the world's high environmental standards. Transformer oil two-stage high efficiency vacuum oil filter features: Mainly used for large-scale transmission and transformation voltage equipment above 110KV and national main transformer grid, on-site overhaul of large substation transformers and rapid deep processing of insulating oils such as new oil and imported oil, new oil, imported oil, transformer oil and substation system Vacuum filtration and purification treatment of relatively valuable oils such as capacitor oil and refrigeration oil. The indexes of the products are much higher than the national standards. Compared with the single-stage vacuum oil filter, the dehydration, degassing and impurity removal (mechanical impurities and free carbon) are faster and more thorough, and the oil limit withstand voltage and flash The higher the point, the lower the breakdown voltage of the filter can be increased by 35KV, which reduces the damage of the oil filter due to repeated heating of the general oil filter. The double-stage vacuum with large pumping rate can greatly improve the vacuum environment in the tank to achieve high vacuum, the ultimate vacuum ≤ 5Pa, and the working vacuum ≤ 35Pa, so that the oil temperature remains unchanged during the processing, and the installation is satisfied. Or the need to evacuate the transformer body at the site, greatly shortening the oil treatment period. Unique degassing, dehydration system, complex three-dimensional flashing, can quickly remove liquid water, using UK micro-gram technology, can effectively remove trace water such as dissolved water, efficiently complete degassing, dehydration, treatment of transformer oil, improve oil The insulation strength and the amount of oil.
