Scope of application:
On-site maintenance of transformers in large substations and fast and advanced treatment of new and imported insulating oils.
It can also be used for vacuum filtration and purification of valuable oil such as transformer oil and transformer system capacitor oil and refrigerator oil.
Especially suitable for large-scale transmission and transformation voltage equipment above 110KV and national main transformer network.
It is widely used in power plants, power stations, power companies, metallurgy, petrochemical, machinery, transportation, railways and other industries, especially in plateau areas above 500 meters above sea level.
On the basis of retaining all the advantages of BS vacuum oil filter, Roots vacuum booster system, secondary high vacuum pumping system and fast dehydration and degassing system are added, which overcomes the weakness of the vacuum oil filter that the exhaust volume decreases sharply when the vacuum is high. One cycle is equivalent to the effect of two ordinary high-efficiency vacuum oil filters.
The two-stage vacuum with large pumping rate can greatly improve the vacuum environment in the tank body, so that it can reach high vacuum, the limit vacuum is less than 5 Pa, and the working vacuum is less than 133 3a, which can keep the oil temperature unchanged in the process of treatment, meet the need of vacuum pumping for transformer body in the installation or maintenance site, and greatly shorten the oil treatment period.
After filtration, the oil limit withstand voltage and flash point are higher. After one filtration, the oil breakdown voltage can be increased by 35KV, which can effectively prevent the harm of oil aging caused by repeated heating.
High performance configuration: advanced infrared liquid level control system, pressure protection system and chain protection control of electric oil pump ensure long-term, safe and reliable operation of the equipment.
The whole machine can be operated live or on-line for a long time. The plateau area is equipped with automatic defoaming and defoaming device, which can realize the complete separation of man and machine.
Precise and intelligent degassing structure can quickly remove all kinds of gases in oil, effectively eliminate the generation of hydrogen and acetylene gas, and ensure that the acetylene content in oil is zero after filtration.
Dual purpose: It is a vacuum oil filter and an independent vacuum source. It can vacuum inject power insulation equipment, which can greatly shorten the oil treatment period of transformer installation and maintenance, and is in the leading position of the products in this industry.
