Characteristics, Applications, and Cost Analysis of Dry-Type Transformers

Transformers play a crucial role in power equipment as they can increase or decrease voltage to meet various power demands. Dry type transformer is a special type of transformer whose iron core and winding are not immersed in insulating liquids but are completely exposed to dry gases such as air or nitrogen.

Characteristics of dry-type transformers

1. High safety: Due to the absence of insulation liquid inside, there is no risk of fire or explosion, making dry-type transformers have significant advantages in safety performance.
2. Easy maintenance: Due to the simple structure of dry-type transformers, their maintenance work is relatively simple, without the need for regular oil replacement or inspection of oil quality.
3. High efficiency: Due to advanced copper foil and silicon steel sheets, dry-type transformers have higher efficiency and lower operating costs.
4. Strong adaptability: Dry-type transformers suit rough environmental conditions, such as elevated temperature, high humidity, corrosion, etc.

Application fields of dry-type transformers

1. Power system: In the power system, dry-type transformers are commonly used in substations, switching stations, and distribution rooms to provide efficient and safe voltage conversion services for the transmission and distribution system.
2. Industrial automation: In factories and enterprises, dry-type transformers provide a stable power supply for various equipment, such as production lines, motors, lighting, etc.
3. Construction field: In buildings, dry-type transformers provide electricity to air conditioning systems, elevators, lighting, and firefighting equipment.
4. Data centers and communication facilities: With the advent of the information age, the reliability and stability requirements for power supply in data centers and communication facilities are increasing. Dry-type transformers are widely used in such places.
5. New energy field: Solar and wind power generation facilities usually need to work in remote areas, and dry-type transformers have become ideal choices in these fields due to their high environmental adaptability.

The cost difference between dry-type transformers and oil-immersed transformers

1. Material cost: Dry-type transformers have higher costs because they require more copper and silicon steel sheets to manufacture coils and iron cores. In addition, to protect the coil from external environmental influences, additional insulation materials and protective coatings are required.
2. Manufacturing process: The manufacturing process of dry-type transformers is more complex than that of oil-immersed transformers, requiring higher technology and stricter manufacturing conditions. This leads to higher manufacturing costs and longer production cycles.
3. Maintenance cost: Although the maintenance of dry-type transformers is relatively simple, their service life is usually shorter than that of oil-immersed transformers. Therefore, in the long run, the maintenance cost of dry-type transformers may be higher than oil-immersed transformers.

Maintenance and repair costs of dry-type transformers and strategies to reduce costs

1. Regular inspection: Conduct regular inspections and maintenance according to the manufacturer’s recommendations to ensure the transformer’s normal operation and service life. By promptly identifying and fixing potential issues, greater maintenance costs can be avoided.
2. Preventive maintenance: Implementing preventive maintenance plans, such as cleaning, coating protection, and fastening, can prevent premature equipment damage and reduce maintenance costs.
3. Reasonable planning and layout: Reasonably plan and layout the power system to avoid damage to transformers caused by overloading or overload operation. By optimizing the operation of the power system, the risk of transformer failures and maintenance costs can be reduced.
4. Training and Education: Train and educate operators and maintenance personnel to guarantee they understand the correct usage methods and daily maintenance points for dry-type transformers. This can improve personnel’s work efficiency and maintenance quality, thereby reducing maintenance costs.
