The core theory of smelting is that the furnace charge is preheated by the furnace charge current, and the furnace gas is ionized to form directional high-temperature ion flow-electric arc, so that electric energy is converted into heat energy, and a high enough temperature field is provided for reduction reaction. The safety, stability and energy consumption level of the operation of the electrode depend on the working position of the electrode in the ore-smelting electric furnace. Since the three-phase motor (A, B, C) of the ore-smelting electric furnace belongs to the asymmetric load, the asymmetry determines the imbalance of the work done by the electrode. Currently, most of the existing methods measure whether the voltages of the phases of the three electrodes are consistent to judge whether the end faces of the three electrodes are positioned on the same horizontal plane or not so as to balance the three electrodes.
However, the secondary voltage access of the traditional ore-smelting electric furnace is all at the connection position of the electric furnace transformer and the short net, and is led out by being pressed on the short net screw, and the most common secondary voltage access method is to take the secondary voltage at the uppermost layer or the lowermost layer of a1, b1, c1 or a8, b8 and c8 of the secondary appearance terminal of the electric furnace transformer, because the short net is convenient for wiring.

The voltage collector not only solves the problems, but also ensures that the conductive pulley is always pressed on the corresponding electrode under the action of the spring when the electrodes frequently move up and down, thereby ensuring the reliability of voltage collection.
However, the voltage collector also has the following disadvantages that the long groove is arranged on the fixed rod, so that the electrode frequently moves up and down to drive the measuring rod to elastically move along the fixed rod, the working environment of the ore-smelting electric furnace is full of dust and water vapor containing cement components, the dust and the water vapor enter the fixed rod through the long groove, the dust and the water vapor enable the spring and the measuring rod to be solidified, the measuring rod cannot move, the electrode can bend or even break the motor collector when moving up and down, and the stainless steel pulley can rub the surface of the electrode hard to rub, so that the surface of the electrode is pressed out of a deep pit, and the use of the whole ore-smelting electric furnace is influenced.
