What is a special transformer and what types are there?

Special transformers refer to a type of transformers designed and manufactured to meet the needs of special purposes and special environments. These transformers often have customized designs to suit specific power systems and equipment. There are many types of special transformers, which can be divided into several categories according to their applications and characteristics:

Welding transformer:

Transformers specially used for electric welding can provide appropriate current and voltage to meet the requirements of the electric welding process.
Electric arc furnace transformer:

Special transformers for electric arc furnaces, capable of providing high current and low voltage to meet the operating needs of the electric arc furnace.
Induction heating transformer:

Transformers used in induction heating equipment can provide high-frequency current to cause induction heating of conductors.
Power electronic transformers:

Transformers used in power electronic equipment, such as inverters, rectifiers, etc., are designed to take factors such as high frequency, high temperature, and high voltage into consideration.
Induction cooker transformer:

Transformers specially used for induction cookers can provide appropriate current and frequency to generate electromagnetic fields for heating.
Oil-immersed transformer:

It has special designs such as explosion-proof, moisture-proof, and anti-corrosion, and is suitable for some special environments, such as chemical plants, mines, etc.
Explosionproof transformer:

It is suitable for use in flammable and explosive places. It has a flameproof structure and a special oil immersion method to ensure the safety of the equipment.
UHF transformer:

Transformers used in UHF circuits are usually used in communication equipment, radar systems and other fields.
Marine transformer:

Transformers suitable for ship power systems, with special designs such as anti-corrosion, shock-proof, and moisture-resistant.
Special power transformer:

For some special power supply needs, such as high-precision voltage stabilizing transformers, AC-DC hybrid power transformers, etc.
