晃电再启动柜在化工项目中的应用

The Application of Voltage Sag Restarting System in Chemical Project

简述了晃电产生的原因及其影响,分析了目前常用的几种抗晃电措施的原理及各种不同方式的优缺点。对于化工装置中一些非常重要的低压电动机负荷,通过增加再启动集中控制装置系统应对"晃电"现象的发生,并与相关设备配合使用,保证了重要低压电机的连续运行。

In this paper, briefly describes the causes of the voltage sag and it＇s influence. The principle ,advantages and disadvantages of several kinds of anti-voltage sag measures are analyzed.In regard to some important low-voltage motor, the restarting system is added to deal with＂ voltage sag＂, and coupled with related equipment, it ensures a smooth operation of these important low-voltage motor.
