设计了一种合理的低压无功补偿方案。重点分析了设计方案、投切的依据以及低压侧补偿所涉及相关关键参数的计算

并选用了适用于矿热炉低压动态无功补偿系统的新型组合式电容投切开关。实际工程案例表明该方案能有效提升矿热炉的功率因数、降低系统能耗

可作为矿热炉无功补偿系统设计的参考。

Abstract

A kind of reasonable low-voltage reactive compensation scheme is designed by way of comprehensive analysis of three kinds of reactive compensation modes of submerged arc furnace. The design scheme

switching base and calculation of related key parameters concerning low voltage side compensation are especially analyzed

and the new combined capacitor switching switch which is suitable for lowvoltage dynamic reactive power compensation system of submerged arc furnace is selected. It is shown by the actual project that this scheme can effectively enhance the power factor

reduce energy consumption of the system and can be used as reference for the design of reactive power compensation system of submerged arc furnace.
