Cooling system used in submerged arc furnace short network multicore water cooled cable

Abstract

The invention discloses a cooling system used in a submerged arc furnace short network multicore water cooled cable. The cooling system comprises the multicore water cooled cable and a heat-dissipation system; the heat-dissipation system comprises a tower body, and the top of the tower body is provided with an air outlet; the inside of the air outlet is provided with a draught fan; the lower end of the draught fan is provided with a water collector; the lower portion of the water collector is provided with a water distribution system; the lower portion of the water distribution system is provided with filler; the lower portion of the filler is provided with a water collection basin; the portion, located at the upper end of the water collection basin, of the tower body is provided with a movable ventilation door; the bottom of the water collection basin is provided with a current-conducting plate; the current-conducting plate is connected to a ground lead; a water outlet pipe of the multicore water cooled cable is connected to an inlet of the water distribution system; a water inlet pipe of the multicore water cooled cable is connected to the water collection basin. The cooling system used in the submerged arc furnace short network multicore water cooled cable is reasonable in structure, and convenient to overhaul and maintain, and has an excellent cooling effect.

Description

technical field [0001] The invention relates to a cooling system for a water-cooled cable, in particular to a cooling system for a submerged arc furnace with a short network and a multi-core water-cooled cable. Background technique [0002] The submerged arc furnace is an industrial electric furnace that consumes a lot of power. It mainly consists of furnace shell, furnace cover, furnace lining, short net, water cooling system, smoke exhaust system, dust removal system, electrode shell, electrode pressing and lifting system, loading and unloading system, gripper, burner, hydraulic system, submerged arc furnace Transformers and various electrical equipment and other components. [0003] The submerged arc furnace is a kind of high energy consumption equipment, and the power loss is very large. During operation, the temperature of the short network cable is as high as 200-320 ℃, and the fault of burning the short network cable often occurs, resulting in frequent shutdown of th...

AI Technical Summary

Problems solved by technology

The reasons for the high temperature of the short network cable are: 1. It is difficult to maintain the cable. After a period of use, it will age and cannot be replaced in time, and the resistance will increase, resulting in high heat; 2. The current is ignored when designing the short network cable. The overload operation condition of the transformer, so the cable heats up too much when overloaded
