With the continuous advancement of science and technology, dry-type transformers, as an efficient and safe power equipment, are increasingly used in the field of power transmission. Compared with traditional oil-immersed transformers, dry-type transformers have many obvious advantages.
1. High safety
Dry-type transformers use air insulation, which will not cause safety accidents such as fire and explosion. At the same time, since there is no oil inside, there will be no oil leakage and other problems and no pollution to the environment. During operation, dry-type transformers have high electrical performance and mechanical strength, which can ensure the stability and reliability of power transmission.
2. Easy maintenance
Dry-type transformers have a simple structure, without oil storage cabinets, safety airways, and a large number of valves, etc. The maintenance workload is greatly reduced.
3. Strong adaptability
Dry-type transformers are suitable for a variety of different environments and use conditions. Whether indoors or outdoors, in mountains, plains or deserts, dry-type transformers can operate stably. In addition, dry-type transformers also have strong corrosion resistance and moisture resistance, and can maintain their performance and life in harsh environments.
4. Energy saving and environmental protection
Dry-type transformers have a high energy efficiency ratio and can effectively reduce energy consumption and carbon emissions. Compared with oil-immersed transformers, dry-type transformers have higher cooling efficiency and can better meet the needs of energy conservation and emission reduction. In addition, dry-type transformers do not produce harmful substances during production, use and recycling, which is in line with the concept of green environmental protection.
5. Simple structure and light weight
Dry-type transformers have a simple structure and are usually composed of only an iron core, windings, arc extinguishing devices and cooling devices. At the same time, since dry-type transformers are enclosed in a metal shell using insulation materials, there is only one axial magnetic circuit in the iron core structure, and there is no eddy current loss, which effectively reduces the loss of the iron core. Therefore, the weight of dry-type transformers is lighter than that of oil-immersed transformers. Under the same capacity conditions, the lighter the weight and the smaller the size of the transformer, the better the operating safety.
6. Low loss and low noise
Dry-type transformers focus on reducing losses and noise during the design process. By adopting advanced materials and processes, dry-type transformers can significantly reduce no-load losses and load losses and improve energy efficiency. At the same time, the noise level of dry-type transformers is low and will not interfere with the surrounding environment and personnel. This feature makes dry-type transformers have significant advantages in places that require a low-noise environment, such as hospitals and schools.
7. Good insulation performance
The insulation performance of dry-type transformers is better than that of oil-immersed transformers, and they have better lightning impact resistance and moisture resistance.
8. Wide range of applications
Dry-type transformers do not require oil pools and cooling systems, have compact structures, and occupy a small area. They are suitable for cities, large industrial and mining enterprises, basements, and other occasions. At the same time, dry-type transformers can also adapt to a wide range of voltages and frequencies, providing more flexible and diverse options for power transmission and distribution systems.
