探究变频调速对起重机的影响及对策

Probe into the Influence of Frequency Conversion Speed Regulation on Crane and its Countermeasures

发达国家的许多电动起重机都是由变频调速系统控制的。近年来,我国在门座式起重机、塔式起重机、装卸桥、集装箱起重机、造船门式起重机、高等级桥式起重机、门式起重机以及对速度性能和定位精度要求很高的起重机当中均使用了变频调速。文章讨论了变频调速对起重机的影响及对策。

Many electric cranes in developed countries are controlled by frequency conversion speed regulating system. In recent years, in China, gantry cranes, tower cranes, loading and unloading bridges, container cranes, shipbuilding gantry cranes, high-grade bridge cranes, Gantry cranes and cranes that require high speed performance and positioning accuracy use frequency conversion speed regulation. This paper discusses the influence of frequency conversion speed regulation on crane and its countermeasures.
