Product Description

A three-phase (single-phase) dry-type autotransformer refers to a transformer whose primary and secondary windings are on the same winding. The primary and secondary windings are directly connected in series and self-coupled. According to the structure, it can also be subdivided into adjustable pressure type and fixed type.
Autotransformers are widely used in power systems and can be used to regulate voltage, realize transmission and distribution of electric energy, etc.
Autotransformers are also widely used in the field of industrial control. For example, it can be used to adjust the starting current of the motor, control the speed and steering of the motor, etc. In addition, it can also be used for the protection and detection of power equipment, inductive heating, etc.
Autotransformers are also widely used in the communications field, for example, they can be used as modulation transformers. In addition, it can also be used for communication equipment fault protection, digital modulation, etc.

Product Features

1.The most prominent feature of an autotransformer is that it saves copper. The amount of copper used in an autotransformer is less than a two winding transformer of the same ratings.

 

2.The single winding used in the autotransformer significantly reduces its size & weight.

 

3.Having small size & weight of the autotransformer.

 

4.The voltage regulation is much better than the two-winding transformer because of the elimination of the losses in the second winding.

Due to the electrical conduction, magnetic induction & reduction in the losses due to the second winding, the efficiency of the autotransformer is higher than the two-winding transformer.

WORKING CONDITIONS:

○ Altitude no more than 1000m
○ Max.Temperature+45ºC
○ Max.Average temperature per day+35ºC
○ Max.Average temperature per year+25ºC
○ Min.Temperature-30ºC(applicable for out-door transformer)
○ Min.Temperature-5ºC(applicable for in-door transformer)
○ Relative humidity≤90%
○ Wave of power supply voltage approximately sino-wave
○ Multi-phase power supply should be approximately symmetric
 

Three Phase Dry Type Transformer Core 

The core is beveled and stepped for maximum performance and minimal bulk. After the magnetic steel is produced by the cutting machine, it is continuously cut into specific lengths by the automatic stacking machine, and then automatically stacked. The correct size is ensured during the entire stacking and assembly process to ensure the high quality of the product.

Dry Type Distribution Transformer Winding

The low voltage winding adopts the whole section of copper foil, which is wound on the special low-voltage foil winding machine with the F-grade insulation. The foil coil solves the outstanding problems such as low voltage, high current coil winding, high short-circuit stress, unbalanced ampere turns, poor heat dissipation effect, windingspiral angle, unstable manual welding quality and so on. At the same tim-e, the winding ends of our company aresealed with resin, cured and formed, moisture-proof and antifouling. The lead copper bar is automatically welded byargon arc welding.

Dry Type Power Transformer Accessories

All the accessories you need to customize our products to your needs.
The casing is made from bolts on a steel plate with removable panels for attachment and tape. Depending on the application and your requirements, the surface treatment can be galvanized, painted. The design is optimized to ensure the required cooling of the transformer at all levels of protection. The enclosure can be shipped assembled on the transformer or flat packed for on-site assembly.
