化工装置中低压电动机供电回路的防“晃电”措施

Anti⁃voltage Sag Measures of Low⁃voltageMotor Supply Circuit in Chemical Plant

根据化工装置的特点及其对电气供用电的可靠性、连续性、稳定性要求,结合“晃电”产生的原因、危害和主要影响,对低压配电系统“晃电”问题进行综合分析,采取相应防“晃电”措施,形成适用于各种条件下的低压电动机防“晃电”方案。

According to the characteristics of the chemical plant and its requirements of reliability,continuity and stability of electrical power supply,combined with the causes,hazards and main influences of voltage sag,a comprehensive analysis of voltage sag problems in low⁃voltage distribution system is carried out.With corresponding anti⁃voltage sag measures adopted,an anti⁃voltage sag scheme for low⁃voltage motor supply circuit is developed,which is suitable for various conditions.
