[0002] As a large-scale smelting equipment for corundum products and magnesium ore smelting, the electric melting furnace's main function is the electrolysis process to promote the fusion and crystallization of raw materials. This process is a high-voltage, high-current excitation process. Its power supply device mainly relies on a special electric furnace with variable gears for power supply. During the power supply process, it is connected to the anode tap of the electric melting furnace through a water-cooled cable. This part of the cable is made of special materials, with high cost, high maintenance difficulty, and harsh operating environment. During operation, as the anode continues to rise and fall, and the cable is in a suspended state, the cable is prone to mechanical fatigue, cracks, breaks, insulation damage and other problems. Because the cable runs in a high-temperature environment for a long time, if it is not inspected and maintained for a long time, it will inevitably accelerate the aging of the cable and cause abnormal conditions, thereby reducing the service life of the cable and increasing maintenance costs.
