What is the future development trend of dry-type power transformers?

Dry type power transformer is a type of transformer that does not use liquid insulation medium, but uses solid insulation material. Due to its small size and weight, which do not require maintenance or oil filling, it is suitable for places with harsh atmospheric environments and limited space. Therefore, it has been widely used in power systems. In the future, with the advancement of technology and changes in market demand, the development trend of dry-type power transformers will present the following changes.

The technical performance of dry-type power transformers will continue to improve. With the continuous introduction of new materials, processes, and technologies, the power density of dry-type power transformers will gradually increase and their capacity will continue to expand. At present, the standard capacity of dry-type power transformers is generally several thousand kilovolt amperes, and in the future, it may reach tens of thousands of kilovolt amperes or even larger. In addition, with the development of digital technology, dry-type power transformers will have a higher level of intelligence and can achieve functions such as remote monitoring, fault diagnosis, and automatic control.

The environmental friendliness of dry-type power transformers will receive higher attention. Due to the absence of liquid insulation media and oil cooling systems, dry-type power transformers have no hidden dangers of oil pollution and leakage, and do not require the replacement and disposal of waste oil, resulting in less environmental impact. In the future, with the improvement of environmental awareness and the strengthening of environmental protection regulations, dry-type power transformers will become equipment in the power system, gradually replacing the application of liquid insulated transformers.

The safety of dry-type power transformers will be further improved. Due to the fact that dry-type power transformers do not use liquid insulation media, there is no risk of oil pollution and explosion, making them safer and more reliable. In the future, with the maturity of key technologies such as relay protection, fault diagnosis, and isolation switches, the safety of dry-type power transformers will be further guaranteed, reducing the occurrence of system short circuits and fire accidents.

The manufacturing cost of dry-type power transformers will gradually decrease. The manufacturing process of dry-type power transformers is relatively complex, resulting in higher costs. In the future, with the improvement of manufacturing processes and the promotion of large-scale production, the manufacturing cost of dry-type power transformers will gradually decrease, more in line with market demand. In addition, due to the fact that dry-type power transformers do not require maintenance and oil filling, their operating costs are also lower, which can save users some costs.

The application fields of dry-type power transformers will be further expanded. At present, dry-type power transformers have been applied in urban distribution systems, industrial power systems, and grid access to solar and wind power generation. In the future, with the rapid development of new energy and the upgrading of power systems, dry-type power transformers will be widely used in microgrids, electric vehicle charging stations, data centers, high-rise buildings, tunnels and other places, providing more reliable guarantees for the stable operation of the power system.

In summary, the future development trend of dry-type power transformers will present characteristics such as high performance, environmental protection, safety, low cost, and wide application. With the advancement of technology and changes in market demand, dry-type power transformers will continue to innovate and improve, providing better technical support for reliable power supply and energy transformation of the power system.
