An outdoor dry transformer having a shield made of a high functional fiber.

A transformer includes a primary and a secondary, the primary is coupled with the converter circuit.

A transformer Includes a primary and a secondary, the primary Is coupled with the converter circuit.

The primary and secondary each Include a single winding.

The primary and secondary each include a single winding.

An compact dry transformer (1A) comprising a magnetic material core (2) and a coil assembly (3) assembled onto the core.

The resulting reduction in electricity use can reach 20% in relation to a conventional dry transformer for a building not in use (nights and weekends).

The present invention relates to a dry distribution transformer (1) comprising at least one low-voltage winding (2) and one high-voltage winding (3), concentrically mounted around a core column (1.1, 1.3).

Once the dry transformer of the invention does not explode, the underground installation chambers can be simpler and more economic once they do not need to be resistant to explosion.

The described series circuit transformer has an auxiliary winding (15) as a secondary voltage transformer, besides the secondary winding (11, 12, 13).

An output rectifier circuit Is coupled with the secondary of the transformer.

An output rectifier circuit is coupled with the secondary of the transformer.

The resulting reduction in electricity use can reach 20% in relation to a conventional dry transformer for a building not in use (nights and weekends).

An active part of the dry transformer comprising a core (1) with yokes (2) and limbs (3) having an a longitudinal axis (A) around which LV coils (4) and winding bobbin (5) is placed concentrically.
