Abstract

FIELD: power supply devices of digital hardware components with a high sensitivity to interference. SUBSTANCE: transformer has a magnetic circuit with the primary and secondary windings. Both windings are encapsulated in sheath 8 of resin with a high-frequency ferromagnetic filler. Installed between the primary and secondary windings is a screen of a sheet of current-conducting material with a slit shunted by a resistive component. The secondary winding is divided into sections, with magnetic shunts installed on the ends of each section, a magnetic shunt is installed between the sections. A screen of a sheet of current-conducting material is installed over the secondary winding with a sheath. It is a three-phase transformer with a three-core magnetic circuit, a coil with the primary and secondary windings is installed on the form on each core. EFFECT: enhanced reliability.

Помехоустойчивый трансформатор предназначен для применения в устройствах электропитания цифровых технических средств с повышенной чувствительностью к помехам. Помехоустойчивый трансформатор содержит магнитопровод с первичной и вторичной обмотками. Обе обмотки залиты в оболочку из смолы с высокочастотным ферромагнитным наполнителем. Между первичной и вторичной обмотками установлен экран из листа электропроводного материала с разрезом, зашунтированным резистивным элементом. Вторичная обмотка разделена на секции, на торцах каждой из которой установлены магнитные шунты, между секциями также установлен шунт. Поверх вторичной обмотки с оболочкой установлен экран из листа электропроводного материала. Трансформатор выполнен трехфазным с трехстержневым магнитопроводом, на каждом из стержней которого установлена на каркасе катушка с первичной и вторичной обмотками.The noise-resistant transformer is designed for use in power devices of digital technical equipment with increased sensitivity to interference. The noise-resistant transformer contains a magnetic circuit with primary and secondary windings. Both windings are embedded in a resin sheath with a high-frequency ferromagnetic filler. Between the primary and secondary windings there is a screen made of a sheet of electrically conductive material with a cut, shunted by a resistive element. The secondary winding is divided into sections, at the ends of each of which magnetic shunts are installed, a shunt is also installed between the sections. A screen made of a sheet of electrically conductive material is mounted on top of the secondary winding with a sheath. The transformer is made three-phase with a three-core magnetic circuit, on each of the rods of which a coil with primary and secondary windings is mounted on the frame.
