“晃电”再启动技术在石油化工企业中的运用

Application of restarting technology of voltage fluctuation in petrochemical enterprise

近年来,化工企业生产对动力系统的持续性提出了更高的要求,电动机抗晃电技术也愈加重要。为优化高压电动机抗晃电自启动方案,以一种新型微机型综合保护器为例,结合生产实际提出了晃电后电动机自启动逻辑,详细阐述了实现过程和相关保护设定原则,满足了现代工企业连续生产的需要。

With the development of chemical process recently, the technology of self-start after voltage fluctuation becomes more and more important. To optimize the program of self-start, a novel comprehensive protector MICOM P241 is taken for instance to cmnpile the logic of the self-start. The related protection principle is demonstrated in detail, so as to meet the need of the continuous modem production.
