Разработка лампового генератора мощностью 1,5 МВА частотой 440 кГц

Abstract

Объект исследования работы является высокочастотный ламповый генератор для подачи питания плазматрона. Цель работы – разработка, проектирование и моделирование лампового ВЧ генератора, работающего на блоке соединения двух генераторный ламп ГУ-98А. В процессе работы была спроектирована принципиальная схема генератора и составлена спецификация ее компонентов, а также разработана модель установки в программной среде Matlab Simulink с учетом отдельной проработки блоков подачи питания, лампового блока и выносного. Удалось достичь заданной частоты 440 кГц, высокочастотных колебаний на выходе и достаточной для применяемости генератора мощности 734 кВА. При математическом расчете процесса на продолжительном промежутке времени система показала себя устойчивой, без предельных скачков напряжения и тока, справляющейся с заданной нагрузкой. Генератор, ламповый блок которого, основан на соединение двух ламп ГУ-98А с одинаковыми анодно-сеточными характеристиками оказался эффективным и конкурентноспособным среди своих аналогов с альтернативными ламповыми блоками. Благодаря проделанной работе можно точно сказать, что данная установка имеет большой потенциал и может найти применение как источник питания индукционных плазматронов большой мощности. Его разработки могут улучшить эксплуатацию установок, упростить замену ламповых блоков и быть фундаментом для дальнейшего развития и модернизации лампового генератора для потенциально новых научных разработок. При углублении исследования данного генератора можно найти способ увеличения мощности путем внедрения специального блока-согласователя.

The object of research is a high-frequency tube generator for supplying power to the plasmatron. The purpose of this work is to develop, design and model a high-frequency tube generator operating on the connection block of two GU-98A generator lamps. In the process, was designed schematic diagram of the generator and specification of its components, and developed a model fitting in the software environment Matlab Simulink, taking into account individual study blocks the power supply of the lamp unit and the remote. It was possible to achieve a set frequency of 440 kHz, high-frequency vibrations at the output and sufficient for the use of a 5 kW generator. When mathematically calculating the process over a long period of time, the system proved to be stable, without extreme voltage and current surges, coping with a given load. The generator, whose lamp block is based on the connection of two GU-98A lamps with the same anode-grid characteristics, proved to be effective and competitive among its analogues with alternative lamp blocks. Thanks to the work done, we can say for sure that this installation has a great potential and can be used as a power source for high-power induction plasmatrons. Its developments can improve the operation of installations, simplify the replacement of lamp units, and be the Foundation for further development and modernization of the lamp generator for potentially new scientific developments. When you deepen the research of this generator, you can find a way to increase the power by introducing a special block-Converter.
