变频调速装置在秦煤三期斗轮取料机行走系统中的应用

Application of VVVF Transducer to Hoofing Part of Bucket Wheel Reclaimers in Phase III of Qinhuangdao Coal Terminal

本文简介了变频调速技术的基本原理,并介绍了应用此技术的变频器在生产中的应用,它不仅拥有控制简单、节能等优点,而且功能强大,可以较好地控制交流电机的速度,使之性能可与直流传动相比。

An introduction to the fundamentals of the VVVF technology is presented in the paper together with the application of the VVVF transducer, which is highly functional,energy saving and simple to operate and control.With the VVVF transducers,the timing performance of AC electromotors can be as better as that of DC driving.
