МЕТОДЫ АНАЛИЗА И УПРАВЛЕНИЯ ЛАМПОВЫХ ГЕНЕРАТОРОВ ДЛЯ ЭЛЕКТРОТЕРМИИ

Abstract

The article presents high-frequency tube autogenerators that are capable of providing energy for various technological loads. The scope of use, the control method, as well as the system of automated study of lamp generator circuits are presented. The modes of operation of lamp generators were considered to create reliable sources with high energy performance. The generator lamp appears to be an equivalent circuit consisting of two dependent current sources, one of which is determined by anode characteristics, the other by grid characteristics. Automation of research is provided by the elements of the model control unit, which allow determining the switching moment of key elements, measuring voltages and currents of various sections of the circuit, and modeling piecewise linear characteristics of nonlinear resistors, inductors, and capacitances. An analysis of the operating modes of various generator lamps used in industry has shown that their load characteristics qualitatively retain their appearance in the power range of 4-500 kW. LG control is carried out by regulating rectifiers, however, grid control is a promising direction, which, in addition, makes it possible to carry out pulsed heating and processing of parts according to optimal algorithms.
