What is the current status of the application of dry-type transformers?

Dry-type transformers, as a type of oil-free transformer, have unique advantages and are widely used in modern power systems. Sincedry-type transformers do not use oil as an insulation and cooling medium, they avoid potential risks such as fire, explosion, and pollution. This makes dry-type transformers safer and more environmentally friendly in both installation and usage, allowing for more flexible and widespread applications in various environments.

1. Application Areas

(1) Power Systems:

Dry-type transformers are extensively used in almost all electrical systems, including power plants, factories, hospitals, schools, commercial buildings, and residential complexes. In these settings, dry-type transformers are the preferred equipment for power supply systems due to their safety and environmental benefits. With their losses and noise levels reduced to new lows,dry-type transformers can be installed in the same distribution room as low-voltage distribution equipment. This not only saves space but also simplifies installation and maintenance work.

(2) Marine Oil Platforms:

Dry-type transformers are also widely used onmarine oil platforms. The presence of moisture and salt mist in marine environments makes traditional oil-immersed transformers prone to insulation degradation and oil leakage. In contrast, dry-type transformers, with their oil-free design, avoid these risks.In marine oil platform power systems, the safe and reliable operation of dry-type transformers is crucial. For the unique challenges of marine environments, such as partial discharge and localized overheating issues in insulation, online monitoring systems can provide real-time status monitoring to ensure the stable operation of both the transformer and the entire power system.

2. Technical Advantages

(1) Safety and Environmental Protection:

Dry-type transformers, lacking oil, do not pose risks of fire or explosion. Their environmental performance also makes them more suitable for areas with stringent environmental requirements. The absence of separate fire protection andexplosion-proof designs simplifies installation and reduces costs.

(2) Low Loss and Low Noise:

With technological advancements, the loss and noise levels of dry-type transformers have continually decreased, resulting in higher energy efficiency and quieter operation. Their low noise characteristics are particularly suitable for environments with strict noise requirements, such as hospitals, schools, and high-end residential areas.

(3) Simple Maintenance:

Dry-type transformers do not require regular oil replacement or treatment, reducing maintenance workload and costs. Their simple structure and low fault rates also make maintenance more convenient.

3. Challenges and Prospects

Although dry-type transformers show significant advantages in many aspects, their challenges in specific environments and applications should not be overlooked. For instance, in high-humidity and high-pollution environments, the insulation materials ofdry-type transformers may be affected, impacting their performance and lifespan. Therefore, ongoing improvements and optimizations in insulation materials and technologies are essential for future development.

Additionally, with the advancement of smart grids, the trend towardssmart and digital dry-type transformers is also emerging. Integrating online monitoring and diagnostic systems can provide real-time monitoring of the transformer’s operating status, prevent potential failures, and enhance the reliability and lifespan of the transformers.

En résumé

Overall, dry-type transformers occupy an important position in modern power systems due to theirsafety,environmental friendliness,low noise,and low loss. With continuous technological advancements and expanding applications, dry-type transformers will demonstrate their advantages in more fields, becoming an indispensable component of power systems.
