The whole sealing oil-immersed power transformer has the advantages of low loss, low noise, high efficiency, can obtain good energy saving effect and reduce pollution. Totally enclosed comparing with ordinary oil-immersed transformer, cancel the oil storage tank, the oil volume changed by corrugated tank elastic corrugated chips to automatically adjusting, transformer is isolated from the rest of the air, to prevent and slow the deterioration of oil and insulation aging, enhance the operation reliability.

DL/T 572 transformer operation procedures
1. Transformer core uses the import high quality cold rolled silicon steel sheet pile, and greatly reduce no-load loss and no-load current, and the core are binding, guarantee the iron core of compactness, and reduce noise.
2. High and low voltage winding with oxygen frees copper winding, low voltage winding double cylinder structure is used to 500 kva and below. More than 630 kva and adopts double helix or four helical structure, high voltage winding adopts multilayer cylindrical structure.
3. Transformer connection group uses the Dyn11, reduce the influence of the harmonic of power grid, and improve the quality of power supply.
4. Transformer is fully sealed structure, prolong service life, avoid hanging core, maintenance free.
5. The measured noise value is lower than the standard.
This series transformer after normal transportation, do not need to lift core check, can install the relevant parts and components, project acceptance test, after qualified can be put into operation.
Conditions of Use:
1. The highest temperature: + 40 ℃
2. The lowest temperature: 25 ℃
3. Altitude: < 1000 m
4. The highest monthly average relative humidity: 90% (20 ℃)
5. Installation location: installed in no fire and explosion danger, serious foul, chemical corrosion and the site of violent vibration, indoor or outdoor.
