Application scenarios
This transformer is widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Due to its high level of resistance to short circuit and lightning strike, it also has the characteristics of flame retardancy, moisture resistance, dust resistance, and low noise, and is particularly suitable for installation and use in places with high fire protection requirements such as flammable and explosive places.
Transformer loading and unloading and transportation
During the loading and unloading and transportation of transformers, it must be ensured that there is no severe shock and vibration. For transformers with a voltage of 220kV and above and a capacity of 150MV·A and above, a three-dimensional shock recorder should be installed, and the shock value should be ensured to comply with the provisions of the manufacturer and equipment technical documents. In addition, transformers filled with dry gas for transportation must also maintain the gas pressure in the oil tank between 0.01-0.03MPa, the dry gas dew point is lower than -40℃, and the positive pressure is always maintained, and a pressure gauge is set for monitoring.
