高压变频调速器在矿井提升机的应用研究

摘要

本文以我国某矿提升机系统为例，分析了该矿提升机系统存在的问题，结合这些问题，应用高压变频调速器对其进行了改造，实现了软启动和软停止，节能效果显著。%Taking enhancing machine system as an example in this paper. First of all, it the question existing in the system were analyzed, combining these problems, through the transformation of the high voltage frequency converter, after the transformed, the whole system is stable and reliable,and does not appear relatively large fault, which achieved a better soft start, soft stop, obvious energy saving effect, investment and low maintenance cost.
