摘要

现场总线控制系统(FCS)屏蔽/接地直接关系到控制系统的监测控制精度和机组的安全、可靠、稳定运行。对此

以基金会现场总线(FF)和过程现场总线(Profibus)为例

对FCS屏蔽/接地进行分析

并给出了FCS防止外部电击、雷电、强电流及静电干扰的电缆屏蔽层接地方法。

Abstract

The mechanism of parse screen/earthing of the field bus control system is directly related with the system supervision and control precision

and the safe

reliable and stable operation of power generation units.This paper gives an analysis to FCS screen/earthing based on FF and FROFIBUS

and presents a method of cable screen /earthing

so as to prevent influence by outside electric attack

lightening

strong current and static electricity disturbance.
