摘要
DCS系统的可靠接地是保证化工厂DCS安全和可靠运行的首要条件。根据一些化工厂的系统设计和现场经验,对DCS系统的接地进行了探讨,提出了直流工作地悬空的处理方法。
The reliable grounding system for distributed control system （DCS）is the prerequisite of ensuring the safe and reliable operation of DCS in a chemical plant. Based on the system design and field practical experience, the grounding system for DCS was discussed, the way that the grounding of direct circuit was hung in the air was brought up.
