Abstract

FIELD: electric engineering. SUBSTANCE: device has coaxial high-voltage and low-voltage windings which are located on magnetic circuit. High-voltage winding has greater diameter and at least one screen is located between windings and is insulated from them. In addition second screen is located on outer side of high-voltage winding. Screen which is located between windings is connected to magnetic circuit and is grounded; second screen is connected to high-voltage winding. This results in possibility to exclude appearance of high voltage in low voltage circuit of transformer. EFFECT: increased reliability, increased safety.

Изобретение относится к области электротехники, в частности, трансформаторостроению. Изобретением решается задача создания трансформатора, обладающего высокой надежностью и безопасностью, исключающего попадание высокого напряжения в низковольтную цепь трансформатора. Для этого в трансформаторе, содержащем концентрически размещенные на магнитопроводе обмотки, низковольтную и высоковольтную, имеющую большой диаметр, и по крайней мере один экран, установленный между обмотками и изолированный от них, предложено, введен второй экран, размещенный снаружи высоковольтной обмотки и электрически с ней соединенный, при этом экран, расположенный между обмотками, соединен с магнитопроводом и заземлен.The invention relates to the field of electrical engineering, in particular, transformer construction. The invention solves the problem of creating a transformer with high reliability and safety, eliminating the ingress of high voltage into the low-voltage circuit of the transformer. For this, in a transformer containing windings concentrically placed on the magnetic circuit, low-voltage and high-voltage, having a large diameter, and at least one screen installed between the windings and isolated from them, it is proposed that a second screen is inserted, placed outside the high-voltage winding and electrically connected to it while the screen located between the windings is connected to the magnetic circuit and is grounded.
