■ 概述 General
電爐變壓器是工業電爐冶煉用變壓器,它是根據各種電爐工作特性和運行特 點而設計制作的專用變壓器。它包括煉鋼電弧爐變壓器、鋼包精煉爐變壓器、電 渣爐變壓器、礦熱爐變壓器(鐵合金爐、電石爐、黃磷爐等)、工頻爐變壓器等 各種交流爐變壓器。
本廠制作的電爐變壓器分兩類:一類是按現行國家標準規定設計生產的標準 型電爐變壓器,另一類是在標準型電爐變壓器的基礎上根據各類電爐冶煉工作特 點、本著提高冶煉效率、降低綜合電力消耗、加強運行可靠性為原則而開發的新 一代電爐變壓器。
Electrical furnace is the transformer used by industrial smelting furnace, which is the special transformer designed and manufactured according to the operating characteristics and operating characteristics of various furnaces. It consists of steel-making electric arc furnace transformer, ladle refining furnace transformer, electroslag furnace transformer, submerged arc furnace transformer (ferroalloy furnace, calcium carbide furnace, phosphorus furnace, etc.), line frequency furnace transformers and other AC furnace transformers. There are two types of furnace transformers produced by the factory: one is standard furnace transformer designed according to current national standards, and the other is the new generation of electric transformer on the basis of standard electric furnace transformers and according to the smelting working characteristics of various types of electric furnaces, in line with the spirit of improving efficiency, reducing overall power consumption and strengthening the operating reliability.

■ 煉鋼電弧爐變壓器 Steelmaking EAF Transformers
煉鋼電弧爐變壓器是根據電爐煉鋼生產對電源的特殊要求而設計、制造的專用變壓器。除一般變壓器的特性外,主要滿足 煉鋼工藝對變壓器機械強度、電器強度、穩定性和電壓調整的特殊要求,解決特殊技術難題。 根據電爐冶煉煉用電制不同,變壓器也對應有普通功率(RP)電弧爐變壓器,高功率(HP)及超高功率(UHP)電弧爐變 壓器系列。
電弧爐變壓器是煉鋼電弧爐的電源變壓器,電弧爐變壓器容量根據電弧爐大小及冶煉工藝(普通功率、高功率、超高功率 配置)。它是通過調壓方式滿足冶煉工藝的要求。調壓方式分為有載調壓和無勵磁調壓兩種。有載調壓的大型電弧爐變壓器不 帶串聯電抗器,無勵磁調壓的中小型電弧爐變壓器其結構形式可分為帶串聯電抗器的和不帶串聯電抗器的兩種,這兩種結構能 在最高二次電壓下改變阻抗。前者靠串聯電抗器的投入和切除來改變阻抗。而后者則靠改變電弧爐變壓器自身高壓繞組的聯結 方式來改變繞組阻抗。
Steelmaking EAF transformer is a kind of special transformer that is designed and manufactured based on the special requirements of power supply by electric furnace steel making production. In addition to general characteristics of the transformer, it is mainly to meet the special requirements on the transformer mechanical strength, electrical strength, stability and voltage regulation by steel-making process, and solve specific technical problems.

According to different power utilizing institutions of EAF smelting, transformer also correspondingly has several series that are general power (RP) electric arc furnace transformers, high power (HP) and ultra-high power (UHP) electric arc furnace transformer.
Electric arc furnace transformer is the power transformer of steel-making electric arc furnace; electric arc furnace transformer capacity is based on the size of electric arc furnace and smelting process (general power, high power, ultra-high power configuration). It meets the requirements of the smelting process by regulating the voltage. There are two ways of voltage regulation: load voltage regulation and non-excitation voltage regulation. The large electric arc furnace transformer in load voltage regulation is without series reactor, while the structure of the small and medium electric arc furnace transformers in load voltage regulation can be divided into the one with series reactor and the one without series reactor, whose structures can change impedance under highest secondary voltage. The former relies on the input and remove of series reactor to change the impedance. While the latter relies on changing the high voltage winding connection way of electric arc furnace transformer to change the winding resistance.
