摘要
低频电源供电的埋弧炉具有许多优点,我公司生产的低频埋弧炉已在国内许多冶金厂运行,取得了良好的效果。为了使低频电源更加可靠地运行,不出事故,给出了低频变频器中主要参数的计算公式及提出了改善动力特性的措施。最后给出了最佳的无电流中断时间t_n,供设计和使用该产品的单位参考。
The thyristor low frequency submerged arc furnace (SAF) has significant advantages, the low frequency SAF produced by Shaanxi Hongye Science and Technology Development Co., Ltd. has been already operated in some ferroalloy factories. In order to that the low frequency power supply can reliablely operater, the main parameter calculation of the low frequency converter was recommended. The improvable method of dynamical characteristic was introduced. Finally the optimal without current break offtime ofthyristor was given.
