浅谈化工装置中仪表线路的工程设计

Brief Discussion on Engineering Design of Instrument Circuit in Chemical Plant

针对化工装置仪表线路所包含的仪表电缆、防爆电缆接头、现场仪表接线箱等组成部分的分类及选型进行了阐述。对仪表线路不同的敷设方式之间的优缺点进行了剖析,提出了电缆槽架空敷设方式是目前在化工装置中比较理想的敷设方式。根据规范要求并结合工程实际,提出了现今比较成熟可靠的仪表线路工程设计方案,并提出了仪表线路工程设计中的注意事项。

This paper analyzes the advantages and disadvantages of different laying methods of instrument lines,and puts forward that the overhead laying method of cable trough is an ideal laying method in chemical plants at present.According to the specification requirements and combined with the engineering practice,the author puts forward the relatively mature and reliable instrument circuit engineering design scheme,and puts forward the matters needing attention in the instrument circuit engineering design.
