摘要
提高仪表供配电系统的可靠性,是确保大型石化装置安全稳定运行的重要因素。该文详细介绍了仪表用电设备的特点,并对目前石化装置中应用较多的仪表供电方案进行了分析,并以内蒙古某公司20万吨/年己内酰胺工程为例,提出了一种与大型石化装置相匹配的仪表供配电系统方案。
Improving reliability of instrument power supply system was very critical to safe and stable operation of large-scale petrochemical plants works.This paper discussed detailed on instrument electrical equipment characteristics and analyzed several most common power supply plans that applied to petrochemical production.Based on 200 kt/a CPL project of an Inner Mongolia Company as an example.Project and above statements,an improved power supply plan was raised for broad-scale petrochemical equipment.
