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. Low loss characteristics
Compared with traditional oil-immersed transformers, dry-type transformers show lower levels of no-load loss and load loss. No-load loss, that is, the power loss of the transformer when the no-load operation at the rated voltage, is mainly composed of hysteresis loss and eddy current loss of the iron core. Dry-type transformers effectively reduce hysteresis loss and eddy current loss by optimizing the iron core structure and using high-quality silicon steel sheets, thereby reducing no-load loss. Load loss is the power loss of the transformer when it is running at rated load, which is mainly composed of copper loss caused by winding resistance and additional loss caused by leakage magnetic flux. Dry-type transformers use low-loss wire materials and reasonable winding design to further reduce load losses.
2. No cooling equipment required
Modern dry-type transformers use a variety of efficient cooling technologies, such as fan-assisted cooling, natural air cooling and forced air cooling. These cooling technologies can significantly improve the heat dissipation efficiency of the transformer, ensure its stable operation under high load, thereby reducing overheating losses and achieving energy saving. In contrast, oil-immersed transformers require a large amount of cooling oil, which not only increases operating costs, but may also affect the normal operation of the equipment due to excessively high oil temperatures.
3. Use of environmentally friendly materials
Dry-type transformers use high-quality materials in the production process and reduce energy loss through process optimization. The conductive materials used in modern dry-type transformers have low resistivity, which means that the loss when current passes through is greatly reduced. At the same time, advanced production technology and fine processing technology are used to ensure the stability of product quality, thereby achieving the best energy-saving effect.
4. Low maintenance cost
The structure and principle of dry-type transformers are relatively simple, and maintenance is relatively convenient. In daily use, you only need to regularly check whether the external insulation layer is damaged, whether the transformer is overheated, etc. Since there is no oil inside, there is no need for maintenance such as replacement or cleaning, which reduces maintenance costs and time, and also reduces energy waste caused by improper maintenance.
5.Reduce carbon dioxide emissions
By controlling losses, dry-type transformers can reduce carbon dioxide emissions during use, meeting the requirements of energy conservation and emission reduction.
As a highly efficient and safe power equipment, dry-type transformers have the advantages of low loss, no need for cooling equipment, and the use of environmentally friendly materials etc. In practical applications, these advantages make dry-type transformers an ideal choice in the field of power transmission. With the continuous advancement of technology and the continuous expansion of application needs, dry-type transformers will continue to play an important role in the future and contribute to the development of the power industry.
