摘　　要：近年来场站由于遭到雷击使仪表失灵产生故障的事故呈现上升趋势,这给控制系统的正常运行带来了很大的隐患,因此,在场站的设计中,仪表控制系统的防雷和接地的重要性也日趋明显。通过实际工程案例,对场站中仪表控制系统接地方式和方法进行阐述,并对场站中接地系统常见问题进行分析,并给出了相应的措施。In recent years, the number of accidents by instrument failure due to lightning strikes has shown an upward trend,this brings great hidden dangers to the normal operation of the control system. Therefore, the design of lightning protection and grounding of instrumentation control system is very important in the process of station design. Through actual case, this paper expounds the grounding method of the instrument control system in the station, and analyzes the common problems of the grounding system in the station.
