Abstract

The invention relates to transformers with twisted toroidal magnet baud. The purpose of the invention is to reduce the level of vibration and noise of a transformer. The device contains a twisted toroidal magnetic core 1 with insulating rings 2 mounted on the ends, fixed with a retaining band on which the winding 3 is wound. The width of the rings 2 exceeds the radial size of the cross section of the magnetic core so that the edges of the rings protrude beyond its lateral surfaces, providing a separating air gap between the winding 3 and the side surfaces 4 of the magnetic circuit 1. When the radial size of the magnetic circuit changes due to magnetostriction, the magnetic circuit vibrates freely IT in the radial direction relative to rings of insulating material in which there are no magnetostrictive phenomena, and due to the separating air gap is not transmitted directly to the winding. 2 з, п.ф-л. 4il.
