Performance characteristics of oil-immersed fully sealed distribution transformer
Compared with S9 transformer, the no-load loss of S11 transformer is reduced by about 30% on average.
The capacity of 630~2500kVA low-voltage winding in the range of cylindrical or spiral structure, high mechanical strength, ampere-turns distribution balance, the product short circuit resistance is good.
(3) The body added a positioning structure, so that it does not produce displacement in the process of transportation, at the same time all fastening fastening nut, to ensure that the product in the long-term operation of the fastening place is not loose, to meet the requirements of no hanging core.
The transformer adopts corrugated tank, cancels the oil storage tank, the cover and the box along the completely welded or bolted, prolonging the service life of the transformer oil.
The product surface by degreasing, rust, phosphating treatment after spraying primer, finish paint, can meet the special requirements of metallurgy, petrochemical system and wet dirty area.
Selected components, the use of fully sealed transformer tank, according to the standard requirements installed pressure release valve, signal thermometer, gas relay, etc., to ensure the safe operation of the transformer. The series of products beautiful appearance, small volume, can reduce the installation area, is the ideal maintenance free quality products.
Low noise: compact design, the application of new materials and new process, reduce noise, noise is lower than the traditional product 5-10dB, no oil storage tank, lower than similar products. During the normal life, there is no need to change oil, which improves the safety and reliability of power grid operation
Dust transformer packaging, the use of vacuum oiling process, completely remove the moisture in the transformer tank. Sealed transformer does not contact with air, effectively prevent oxygen and moisture into the transformer and lead to insulation performance decline (insulation materials and oil aging), so there is no need to regularly carry out oil sample test
Reliable long-term service life: fully sealed transformer box cover and box along the bolt connection or welding structure, isolated oil and air contact, insulation will not be damp, greatly reduce the aging speed of insulation, improve the service life.
We will small volume, beautiful appearance: S11-M series transformer tank using corrugated plate radiator, when the oil temperature changes, the change of oil volume by the elastic expansion of corrugated sheet to adjust compensation. Corrugated oil tank beautiful appearance small volume, small footprint.
(11) Free hanging center: fully sealed transformer operation before the user does not need to check the hanging center, the user can save the cost of hanging center inspection. Maintenance-free: Fully sealed transformer does not need maintenance.
