What are the structural characteristics of dry-type transformers?

The structural characteristics ofdry-type transformersconfer unique advantages across various applications, particularly in environments where high safety, reliability, and environmental friendliness are essential. The main structural features of dry-type transformers are as follows:

Content

●Safety, Fire Resistance, and Pollution-Free:

Dry-type transformers, which do not use oil as a cooling and insulating medium, significantly reducefire risks and pollution issues. This characteristic allows them to operate directly in load centers, such as commercial buildings, industrial facilities, and public infrastructure, where fire safety requirements are stringent.

●Advanced Technology and High Mechanical Strength:

Dry-type transformers employ advanced manufacturing technologies from both domestic and international sources. They exhibit high mechanical strength and excellent short-circuit resistance. The structural design incorporateshigh-strength insulation materials and precise manufacturing processes, enabling the transformer to withstand substantial mechanical stress during short circuits without damage. Additionally, dry-type transformers exhibit minimal partial discharge, good thermal stability, and high overall reliability, ensuring stable operation over extended periods.

●Low Losses, Low Noise, and Energy Efficiency:

Dry-type transformers are characterized by low operational losses and low noise levels, which enhance energy efficiency and minimize noise interference in the surrounding environment. Their energy-saving performance is notable, helping to reduce operational costs. Furthermore, theirmaintenance-free design further lowers maintenance expenses and operational complexity.

●Excellent Cooling Performance and Overload Capacity:

The structural design ofdry-type transformersallows for effective heat dissipation. Particularly with forced air cooling, the transformer's capacity can be significantly increased. Through well-designedcooling and air circulation systems, dry-type transformers can operate stably under high load conditions, preventing performance degradation due to overheating.

●Moisture Resistance and Environmental Adaptability:

Dry-type transformers exhibit excellent moisture resistance, making them suitable for operation inhigh humidity and other harsh environmental conditions. This feature makes them appropriate for complex environments, such as humid industrial sites or coastal areas.

●Intelligent Temperature Detection and Protection Systems:

Modern dry-type transformers can be equipped with advanced temperature detection and protection systems, including intelligent temperature control systems. These systems automatically monitor and display the operating temperatures of the three-phase windings and can automatically activate or deactivate fans as needed. Additionally, the systems feature alarms and tripping functions to ensure prompt measures are taken under abnormal conditions, safeguarding theequipment's safe operation.

●Compact Size and Lightweight:

Due to optimized structural design,dry-type transformers are smaller in size and lighter in weight, occupying less space. This not only saves installation space but also reduces installation costs, making dry-type transformers more flexible and economical for urban construction and industrial applications.

In summary

In summary, dry-type transformers, with their excellent safety, reliability, energy efficiency, andenvironmental adaptability, represent a crucial type of transformer in modern power systems, particularly suited for applications with high safety and environmental demands.
