防晃电技术在引风机控制系统中的优化与应用

Optimization and Application of Anti-electricity Dazzling Technology into Cotrol System of Induced Draft Fan

石化厂裂解装置H炉引风机易受电网波动影响。抽屉柜中的接触器在电网波动过程中因线圈失电而脱开,严重影响生产运行,导致装置停车,造成了巨大的经济损失。为避免电网波动对引风机运行造成的影响,对抽屉柜进行技术改造,加装马达保护器,利用它的"防晃电"功能来避免电网波动。通过技术改造,极大提高了供电质量,减少了非计划停车次数。

Based on the special property of production continuously in petrochemical enterprises,and the influence of electricity dazzling,this paper introduces the anti-electricity dazzliang technology and its application,and supplies references to solve motor tripping for electricity dazzliang.
