Description
большой амплитуды, совпадающей по направлению с основным током. При спадении импульсного тока в индуктивности образуетс э.д.с. самоиндукции, котора , складыва сь с напр жением вторичной обмотки, создает на дуговом промежутка в случае холостого хода импульс напр жени , а в случае горени дуги - импульс тока, как это видно на фиг. 2. Импульсы удравлени подаютс на управл ющИе электроды вентилей 7 и 5 в моменты перехода тока через нуль или с некоторой задержкой после этого момента.large amplitude, coinciding in direction with the main current. When a pulse current falls into an inductance, an emf is generated. self-induction, which, when added to the secondary voltage, creates a voltage pulse on the arc gap in the case of idling, and a current pulse in the case of arc burning, as can be seen in FIG. 2. Pulse reduction pulses are applied to the control electrodes of the valves 7 and 5 at the moments when the current passes through zero or with some delay after this moment.
Технико -экономические преимущества предполагаемого изобретени по сравнению с прототипом заключаютс в повышении стабильности процесса сварки на переменном токе и павыщении производительности процесса , а по сравнению с известными процессами газоэлектрической дуговой сварки плав щимс электродом на посто нном токе - в повыщении про.изводительности и улучщении качества сварных соединений за счет снижени разбрызгивани металла.The technical and economic advantages of the proposed invention in comparison with the prototype consist in increasing the stability of the welding process with alternating current and the swelling of the productivity of the process, as compared with the known processes of gas-electric arc welding with a consumable electrode at a direct current, in increasing the productivity and improving the quality of welding compounds by reducing metal spatter.
Предлагаемый источник питани расшир ет область применени автоматической ,и полуавтоматической газоэлектрической сварки плав щимс электродом (в частности, вThe proposed power source expands the field of application of automatic, and semi-automatic gas-electric welding with a melting electrode (in particular, in
углгкислом газе); пО|Вышает качество сварных конструкций и снижает удельный расход электродных материалов (за счет улучшени формы сварных ШВ01В и снижени разбрызгизани ).carbon dioxide gas); o | Enhances the quality of welded structures and reduces the specific consumption of electrode materials (by improving the shape of welded ShV01B and reducing spattering).
