Abstract

Изобретение относится к устройству управления для восстановительных печей (15) переменного тока с электродами (14), которое содержит трансформатор (11) и систему (1) регулирования для регулировки подачи энергии в восстановительных печах (15) переменного тока, которая руководит механизмом (17) перемещения электродов (14), при этом устройство управления дополнительно содержит управляемые силовые электронные переключатели (13) переменного тока, которые включены во вторичной цепи в линии сети низкого напряжения электродуговой печи и при помощи линии (16) зажигания связаны с системой (1) регуляции для подачи управляющих импульсов поджигания, причем устройство управления выполнено таким образом, что кратковременные колебания электрических параметров компенсируются только с помощью переключателей переменного тока.
