DBF2-8Q10 outdoor bottom blowing cooling axial fan with bracket

DBF2-8Q10 outdoor bottom blowing cooling axial fan with bracketIt is a low-noise energy-saving product used in the radiator cooling system of large and medium-sized transformers. It has the characteristics of low noise, stable performance, high efficiency, reliable operation, and long service life, especially CFZ4、CFZ5The series of new products not only have high indicators mentioned above, but also have the characteristics of lightweight and beautiful structure, high reliability, etc, CFZ4、CFZ5The series blowing device is currently one of the relatively low-noise transformer cooling and blowing devices.The impeller adopts low-noise blade type, with riveted impeller, adjustable die cast aluminum impeller and wing integrated impeller. It adopts multiple protection and low-noise technologies, uses imported low-noise bearings, and has a protection rating of IP55, suitable for outdoor use. The normal operation of oil immersed transformers relies on the coordination and cooperation of various components, and the cooling fan, as an important component of the transformer, plays a crucial role in the transformation processIt plays a crucial role in the process of heat dissipation.DBF2-8Q10 outdoor bottom blowing cooling axial fan with bracketdeviceBeside the radiator of the transformer oil tank. Install several fans next to the radiator of the transformer oil tank to change the natural convection of air to forced convection, greatly enhancing the heat dissipation capacity of the radiator. This system becomes an oil immersed air-cooled cooling system, also known as an oil natural circulation or forced air-cooled cooling system.

The CFZ transformer cooling fan is divided into front blowing, rear blowing, and side blowing devices according to the position of the radiator.

During the installation of the cooling fan for oil immersed transformers, the following precautions should be taken:

1.Before installing the fan, it is necessary to turn off the power of the transformer and ensure that there is no power before proceeding with the installation work.

2. InstallationBefore, it is necessary to note the position of the connecting wires of the fan to avoid installation errors. At the same time, be careful not to damage the heat sink when installing the fan.

3.During installation, ensure that the fan is in close contact with the base and there is no looseness. At the same time, the connecting wires should not be tightened excessively to avoid damaging the wire ends.

4. InstallationAfter completion, it is necessary to check again whether all connecting parts are tightened to avoid loosening during subsequent operation.

After the installation of the immersion transformer cooling fan, inspection work needs to be carried out to determine whether the replacement is successful, including:

1.Start the transformer and check if the fan rotates smoothly.

2.After observing the operation of the transformer for a period of time, check if the temperature of the transformer is normal.

3.Observe whether the oil level of the transformer is normal and make necessary additions.
