Abstract
Изобретение относитс к электротехнике. Цель изобретени - улучшение энергетических характеристик. Устройство подключает фазы источника питани к выводам дл подключени нагрузки 35 - 37 при срабатывании блока 27 управлени . Сигнал с блока 27 включает управл емые ключи 26, 29, 31, которые подключают вторичные обмотки трансформаторов 20, 22, 24 к управл ющим переходам тиристоров 1 - 6. Применение трансформаторов 20, 22, 24 обеспечивает включение тиристоров 1 - 6 при переходе их анодных напр жений через нуль без запаздывани тока управлени . 2 з.п.ф-лы, 2 ил.The invention relates to electrical engineering. The purpose of the invention is to improve the energy performance. The device connects the phases of the power supply to the terminals for connecting the load 35 to 37 when the control unit 27 is triggered. The signal from block 27 includes controllable keys 26, 29, 31 that connect the secondary windings of transformers 20, 22, 24 to thyristors 1 to 6 control junctions. Using transformers 20, 22, 24 ensures that thyristors 1-6 are switched on when they pass over anode ones voltage across zero without lag control current. 2 hp ff, 2 ill.
