Abstract
Изобретение относится к способу и устройству для электропитания электродугового плавильного агрегата для плавки и нагрева металла, в частности стали. Устройство содержит источник трехфазного тока, который через средства создания постоянного или переменного тока подает ток, по меньшей мере, на один электрод, выступающий в сосуд плавильного агрегата. За источником (91) трехфазного тока расположены, по меньшей мере, два включенных параллельно модуля (41, 4n) электропитания, каждый из которых содержит соединенные последовательно неуправляемый мост (51, 5n) трехфазного тока, промежуточную схему (61, 6n) постоянного тока и транзисторный блок (71, 7n). За модулями (41, 4n) по направлению тока расположен общий токоподвод (31), по меньшей мере, к одному электроду (21) плавильного агрегата (11) и, по меньшей мере, от одного другого электрода (22 или 24).Отчет о международном поиске был опубликован 2001.04.26.
