徴とする三相交流アーク炉。 Three electrodes inserted into the furnace body and a furnace transformer are connected through three power supply lines, and three-phase alternating current is supplied from the furnace transformer to the electrodes to connect the electrodes and the raw material. In a three-phase AC arc furnace configured to heat, melt and smelt raw materials by generating an arc between the three-phase AC arc furnace, each of the power supply paths is configured by a group of conductors each consisting of two conductors. hand,
These three conductor groups are arranged side by side horizontally, and the two conductors making up each conductor group are spaced apart in the vertical direction, so that the distance between the conductors in the centrally arranged conductor group is The spacing between the conductors of the conductor groups arranged on both sides is narrower than that of the conductor groups arranged on both sides, and the three conductors placed on the upper and lower sides of each conductor group are arranged so that the mutual spacing between them is approximately equal. A three-phase AC arc furnace characterized by a triangular arrangement.
