Abstract
Сварочный трансформатор для инверторного источника питания, содержащий магнитопровод, на котором коаксиально расположены первичная, первая и вторая вторичные обмотки ленточного типа, изготовленные из металлической фольги по принципу спирали Архимеда, отличающийся тем, что в него введена сервисная обмотка, обладающая высоким температурным коэффициентом сопротивления, установленная снаружи первичной обмотки в средней ее части, слева и справа от сервисной обмотки на одинаковом расстоянии размещены соответственно первая и вторая вторичные обмотки, намотанные встречно, при этом каждая из ленточных обмоток состоит из нескольких токопроводящих слоев фольги, изолированных друг от друга диэлектрическими прокладками, причем увеличение частоты источника питания выше 120…150 кГц позволяет использовать конструкцию без магнитопровода. A welding transformer for an inverter power source, containing a magnetic circuit on which the primary, first and second secondary windings of a tape type are coaxially arranged, made of metal foil according to the principle of the Archimedes spiral, characterized in that a service winding with a high temperature coefficient of resistance is installed in it, installed outside the primary winding in its middle part, to the left and to the right of the service winding at the same distance are placed the first and second second, respectively windings wound counterclockwise, each of the tape windings consists of several conductive layers of foil isolated from each other by dielectric spacers, and increasing the frequency of the power source above 120 ... 150 kHz allows you to use the design without a magnetic circuit.
