摘　　要：集散控制系统是自动化仪表控制技术的发展 ,由于集散控制设备中应用集成电路、微电模块这些器件普遍存在绝缘强度低、耐电涌能力差等致命弱点 ,在雷暴气候下 ,常遭受雷击。为了确保炼油化工装置集散控制系统的正常运行 。Distributed control system is the development of the automation instrument technique,because people have applicated many of integrated circuit and tiny electricity modules inside distributed control system apparatus,these equipments have less intension on insulating and can't bear the electric shocking flow normally,this usually cause weakness death,under the thunder weather,these equipments are often striked by thunder striking,in order to keep the distributed control system of the oil refining chemical engineering device working in the right way,this text is discussing about thunder striking and protective on distributed control system.

关 键 词：集散控制 雷击与防护 电源 浪涌
