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 out the short network cable often occurs, resulting in frequent shutdown of the furnace. The operation of submerged arc furnace adopts high current and low voltage working mode, the secondary current reaches 15000A, and the voltage is between 72 and 96V. The current transformer is allowed to be overloaded by 10% to 30%. 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 excessively when overloaded.
