FIELD: electricity.
SUBSTANCE: high-frequency and high-power transformer has a core (1) on which the primary winding (2) is located, on which the secondary winding (4) is insulated. The entire assembly is placed and mounted in an insulator (3), which is made of two parts or halves (6) and (7), symmetrical with respect to the transverse vertical plane. Each part has a hollow tubular element (3.1) located inside the outer body (3.2) of each half of the insulator, forming in each part an annular space (3.3) contained between the outer wall of the tubular element (3.1) and the inner wall of the outer body (3.2), where the secondary or high-voltage winding is located. The insulator (3) has in its outer casing (3.2) a slot (5) made at zero voltage level and through which oil penetrates to the secondary winding.
EFFECT: sizes reduction.
