Transformer oil filter, in fact, is a kind of filter solid impurities in oil, water, improve oil performance, improve the insulation strength of transformer oil mechanical equipment. Transformer oil filter is mainly used in power plants, power stations, power companies, metallurgy, petrochemical, railway and other industrial and mining enterprises to purify unqualified electrical insulation oil special equipment, but also for insulation power equipment vacuum injection, vacuum drying electrical equipment moisture. The following billion electric with you to understand the transformer oil filter a brief overview.
Working principle of transformer oil filterAbout oil machine is working, the oil under the action of pressure difference inside and outside the entrance into the prefilter, larger particles impurities by filter, the oil after multiple infrared heating into special personalized vacuum separator, first to form fog in the vacuum separator, to form the membrane, the contact area to expand in a vacuum for hundreds of times, the moisture in oil in high fever, high vacuum, large surface, high pumping speed under the condition of rapid evaporation and discharge by vacuum system.
The steam discharged from the upper part of the vacuum separator is firstly cooled and dehumidified by the condenser, and then cooled again in the cooler. The condensed water is discharged into the water storage device, and the air is finally discharged into the air by the vacuum pump after two condensations and dehumidification. The dry oil in the vacuum separator after vacuum vaporization and dehydration is raised from negative pressure to positive pressure through the oil pump. After filtration, the net oil is discharged from the oil outlet to complete the whole process of net oil.
Classification of transformer oil filter
Transformer oil filter can be divided into two types: ordinary single set vacuum oil filter and double stage high efficiency vacuum oil filter. The transformer oil filter can remove the moisture, gas and impurities in the transformer oil quickly, improve the lubrication performance of the transformer oil, reduce the rust or corrosion of the oil equipment due to the excessive moisture or impurity content, and extend the service life of the oil equipment.
Characteristics of transformer oil filter
1. Characteristics of ordinary vacuum oil filter for transformer oil:
Three-dimensional flash evaporation, efficient dehydration, degassing; Net filtration combined with polymer adsorption; Automatic infrared liquid level control; Interlocks and protective devices of the trinity; The machine can be used independently or in combination with oil regeneration system. This machine can vacuum oiling and vacuum drying for insulated power equipment such as transformer. It can randomly check the withstand voltage value and automatically print the inspection results (generally for purchase); This machine can be used together with the transformer oil regeneration decolorization device, adding functions such as acid removal, decolorization, carbon removal and dielectric loss reduction. The machine has the function of vacuum oiling and on-line running.
2. Characteristics of transformer oil dual-stage efficient vacuum oil filter:
Double-stage high vacuum transformer oil filter oil machine is mainly used for large pressure power transmission and transformation equipment and the national more than 110 kv main substation online, large transformer substation site maintenance and new oil, imports of oil, insulating oil rapid deep processing, new oil, capacitor oil import oil, transformer oil, and substation system and refrigeration oil more expensive oil vacuum filtration and purification treatment. The product of the indicators were significantly higher than the national standard, compared with the single stage vacuum filter oil machine, dehydration, degassing, removing impurity (mechanical impurity and free carbon) effect more quickly and thoroughly, oil extreme pressure value and higher flash point, a filter can improve the breakdown voltage 35 kv, reduce the average filter oil machine oil aging damage caused by the repeated heating.
The two-stage vacuum with large pumping rate can greatly improve the vacuum environment inside the tank and make it reach a high vacuum, the limit vacuum ≤5Pa, the working vacuum ≤35Pa, so that the oil temperature remains unchanged in the process of treatment, meeting the needs of the installation or maintenance site for the vacuum extraction of the transformer body and greatly shortening the oil treatment period. Unique degaming and dewatering system, compound three-dimensional flash evaporation, can quickly remove liquid water, using UK microgram technology, can effectively remove dissolved water and other trace moisture, efficient completion of degaming, dewatering, treatment of transformer oil, improve the insulation strength and oil content.
