The invention relates to elements of electrical equipment and can be used in electronic equipment.

The purpose of the invention is to simplify the design and improve the mass and size indicators of the incandescent transformer.

The drawing shows the incandescent transformer construction, section.

The filament transformer contains a primary winding 1, a primary winding core 2, a secondary winding 3, a secondary winding core 4, a coupling 5, a central rod 6, an insulation 7. Moreover, the primary winding is wound on its core, the secondary winding is on its own, and the electromagnetic winding communication between them is carried out by means of a coil of communication.

Replacing the volumetric coil of the communication with a flat-CMM and eliminating the electrostatic screen made it possible to remove a significant part of the surface of the secondary winding from the housing (coil of communication) and from the primary winding. As a result, the task of creating a reliable insulation of the secondary winding and its conclusions relative to the housing and the primary winding has been simplified. This is significant, since in the incandescent transformers the insulation is under voltage of ten kilovolts about

In an incandescent transformer, the cross section of the primary winding core is times the cross section of the secondary winding core. This compensates for the decrease in the secondary winding voltage not by increasing the number of turns of the secondary winding.

coils, and by reducing the number of turns of the primary winding. At the same time, there is no increase in current through video | communication current. As a result, the dimensions of the transformer have significantly decreased.

The proposed sassy transformer works as follows.

When the primary winding I is connected to the network, a magnetic flux is induced in the core 2, which creates a current in the turn of the connection 5. This current creates a magnetic flux in the core 4, which outputs the voltage in the secondary winding 3. The capacitance between the windings is mainly determined by the gap 8 between them.
