According to such requirements by the metallurgical and chemical enterprise as energy reduction and loss and production increase to the submerged arc furnace

a kind of high-energy consumption smelting equipment

in this paper

the reactive compensation design in the high

medium and low voltage side of furnace transformer reactive power compensation designs is proposed with combination of the structure features of the submerged arc furnace

with purpose of improving power factor

adjusting furnace condition

enhancing utilization of the furnace transformer and reducing production cost. The im-portance of low voltage phase compensation in the compensation of submerged arc furnace and the principle in the design and type selection of components are proposed so to provide reference in the determination of energy-saving and loss reduction equipment for the metallurgical and chemical industry and

at the same time

to provide assistance to the designers in the submerged arc furnace compensation device.
