摘要
详细介绍 V acon变频器在矿井中的应用 ,该方案中 Vacon变频器作为特殊的低频电源 ,在保持输出频率不变的情况下 ,根据外部控制信号的要求和实际的运行速度 ,控制输出电压的大小 ,实现了矿井提升机高压电机减速段的平稳制动和稳定爬行 ,具有较大的实用和推广价值。
This paper introduces Vacon converter applied to mine lift. In this application vacon converter is a special low frequency power supply. The output frequency of the converter is constant. The output voltage will change according to the pre-setting decrease curve and the real speed of the lift in low frequency brake stage. It realizes smooth brake and stabile creeping of the high voltage motor in mine. It has good utility and spread profit.
