ELECTROLYSIS RECTIFIER ■ INDUSTRY ■ METALLURGY

FUNCTIONS • power supply of electrolysis units for nonferrous metals electrowinning from melts (aluminum, magnesium) and solutions (zinc, copper, nickel, sodium, cadmium, lead, manganese, water, etc.); • power supply of electrolysis units for gas production (chloro, fluoro); • power supply of electro-graphitation furnaces; • similar loads with necessity of high operating currents. APPLICATION • nonferrous metallurgy; • industry. RECTIFYING CIRCUIT • Bridge (B). • «Y-reverse Y with smoothing reactor» (N). Regulation of output current under load - OLTC, angle of thyristors control. BENEFITS: •...

Each arm consists of a series-connected diode (thyristor) and fuse (one or more in parallel) protecting power circuit against short-circuit current. Parallel connection of several circuits «Y-reverse Y with smoothing reactor» with thyristor control of line current value are applied in low-voltage multiampere rectifiers. Power semiconductor devices can be cooled with forced circulation of distilled water, liquid (with antifreeze) or forced air. Heat exchanger for cooling of power converter sections (thyristor or diode) and valveside windings of power transformer, type «water-water», «water-air»,...
