摘要
本文介绍了加能有限公司生产的提升机专用能量回馈单元IPC-PFH系列在煤矿提升机技术改造中的应用,该应有方案中IPC能量回馈单元与ABB变频器配套使用,实现了变频器的四象限运行,解决了重物下放及急停情况下的能量回馈问题,避免了原系统中制动电阻烧坏引起的矿车下行失控,整个系统计既安全又省电。
This paper introduces IPC produce the elevator special-purpose frequency changer in coal mine elevator technological transformations application, explained the frequency changer in the ease of operation, the energy conservation falls consumes, the protection completely and so on the aspect remarkable superiority, had pointed out the promotion applies this kind of special-purpose frequency changer the positive sense.
