摘要
PLC的改造采用交流提升机串电阻调速电控的方式,对这一改造方案进行了进一步的改进,针对原有的不足,提出了新的技术改造方案并进行了测试,最终得到能够平稳运行,可靠性强的,同时精度较高,并且具有节能效果的新型PLC-高压变频器具有更好的安全性和更高的经济效益。
The transformation of PLC adopts the electric control mode of series resistance speed regulation of AC hoist.This paper further improves this transformation scheme.In view of the original shortcomings,a new technical transformation scheme is put forward and tested.Finally,a new type of PLC-high voltage frequency converter with stable operation,high reliability,high accuracy and energy-saving effect is obtained,which has better security and higher economic benefits.
