Due to the flammability of the transformer oil used in oil-immersed transformers, non-flammable and difficult-to-burn insulating liquid transformers have not been widely used due to environmental or cost concerns. Dry-type transformers, which are easy to operate and maintain and pose no fire hazard, have rapidly developed in recent years. 

Dry-type transformers are widely used in various fields due to their safety, efficiency and versatility. (Yawei Transformer can provide you with professional transformer customization services) Because of its main function: voltage conversion, we can see that the high voltage on the transmission line in daily life is reduced to a lower usable voltage through the transformer, so as to facilitate the distribution of power in commercial and industrial environments.

Due to the flammability of the transformer oil used in oil-immersed transformers, non-flammable and difficult-to-burn insulating liquid transformers have not been widely used due to environmental or cost concerns. Dry-type transformers, which are easy to operate and maintain and pose no fire hazard, have rapidly developed in recent years. The standard for dry-type transformers is GB1094.11-2007"The Electric Power Transformer Part 11: Dry-Type Transformers", GB/T10228-2008 "Technical Parameters and Requirements for Dry-Type Power Transformers", and GB/T17211-1998 "Guidelines for Load of Dry-Type Power Transformers."

 

Dry-type eletric transformers can be divided into two main categories: one is the encapsulated type, where the windings are wrapped in solid insulation and do not come into contact with gas. The heat generated by the windings is conducted through the solid insulation and dissipated to the air via the surface of the solid insulation. The other type is the open type, where the windings are in direct contact with the gas for heat dissipation.

1. Industrial equipment application
Mechanical equipment: Powering heavy machinery, motors and other industrial equipment that requires specific voltage levels. Common heavy machinery generally has special requirements for power and voltage levels, so transformers are needed to adjust the voltage. The role of transformers in industrial scenarios cannot be ignored.


2. Application in commercial buildings
Lighting and HVAC systems: Generally speaking, in commercial buildings, the place where power is needed is the lighting and air-conditioning system, so the existence of transformers is to provide voltage conversion for lighting systems, heating, ventilation and air conditioning (HVAC) systems.


3. Power conversion for renewable energy
Power conversion for wind and solar energy: Dry-type transformers can be applied to wind turbines and solar inverters to convert the generated electricity into usable voltage levels, either for transmission or direct use.

4. Power support for data centers
Critical load support for electronic equipment: The voltage reduction effect of dry-type transformers can provide reliable power for servers and network equipment while ensuring the shortest downtime.


5. Power supply support for transportation
Power support for rail transit systems: Dry-type transformers can be used in train stations and transportation systems to power electrical systems in signals and other transportation.


6. Power supply for healthcare facilities
Power support for medical equipment: The application of dry-type transformers in medical systems can ensure stable power supply for sensitive medical equipment and imaging equipment.

 

Dry-type transformers, like various other transformers, are an indispensable part of modern power infrastructure systems. Of course, the various application environments are different. Yawei transformers can provide safe and reliable power solutions for various industries.
