高阻抗电弧炉的电弧稳定性

The Arc Stability of High-impedance Electric Arc Furnace

近年来,随着高阻抗电弧炉长弧操作的运行和泡沫渣的实践,关于电弧稳定性的研究工作显得越来越重要了。影响电弧稳定的最重要因素是运行电抗,因此定量地讨论了运行电抗有关问题。介绍了提高电弧稳定性的主要措施。最后,给出了电弧稳定性判据。

Of late years, with the operation of long arc and foaming slag practice, the need for improved arc stability is becoming more and more important. The most influential factor on arc stability is the operating reactance caused by harmonics induced on the secondary side of the transformer. Thus related operation reactance problems are discussed. The principal methools improving arc stability are introduced. Finally, the arc stability criteia are given.
