摘要

电炉变因冶炼需求而频繁地进行空载合闸

不可避免地产生励磁涌流

影响电弧炉2次滤波支路的安全稳定运行。本文针对某钢铁厂2次滤波支路电容器烧毁的案例

结合励磁涌流的产生机理与实测数据的分析

研究了励磁涌流对2次滤波支路影响的机理

并基于不同类型2次滤波支路的仿真结果

提出了考虑励磁涌流的电弧炉2次滤波支路的设计方法

对电弧炉2次滤波支路的优化设计与安全稳定运行具有重要的指导意义。

Abstract

Frequent no load operation of furnace transformer due to smelt need generates unavoidably exciting inrush current and affects safe and stable operation of the 2 nd filter branch of electric furnace. In view of fuse case of the 2 nd filter capacitor at certain steel plant and with combination of generation mechanism of exciting inrush current and analysis of actually measured data

the mechanism of influence of exciting inrush current on the 2 nd filter branch is studied and

on the basis of the simulation result of different types of the2 nd filter branch

the design method of the 2 nd filter branch of electric furnace considering exciting inrush current is proposed

which has important guidance for the optimization design and stable operation of the 2 nd filter branch of the electric furnace.
