摘要
ABB公司新一代产品ACS800系列变频器(DTC)针对起重机的调速特性和工艺要求,设计可使抓斗式卸船机发挥出最优性能,卸船周期的控制水平与技术最熟练的起重机操作员不相上下甚至更胜一筹。传动系统采用先进的直接转矩控制,达到了响应快、可靠性高、控制效果好的目的。本文对传动系统电气回路的设计进行了论述。
The ABB's new product series ACS800 (DTC) drives can be used for the main motions Hold. Close. Trolley, Boom and Gantry. These are crane dedicated versions of ABB's well known high end industrial drives. These drives with DTC make GSU an excellent pertbrmance. The paper indicates the electrical design of the drive system.
