电气自动化中电气接地及电气保护技术的关键问题研究

Discussion on Key Problems of Electrical Grounding and Electrical Protection Technology in Electrical Automation

自动化控制不仅保障了机电设备的安全运行,还为人们提供了一个安全的生存环境。文中阐述了电气自动化中的电气接地的内涵,包括TN-C-S系统与TN-S系统。重点介绍了电气保护的技术要点,包括交流工作接地系统、安全保护接地系统、防静电接地和屏蔽接地系统、直流接地系统、防雷接地系统等。

automatic control not only ensures the safe operation of electromechanical equipment,but also provides a safe living environment for people.This paper expounds the connotation of electrical grounding in electrical automation,including TN-C-S system and TN-S system.We focus on the technical points of electrical protection,including exchange of grounding system,safety protection grounding system,anti static grounding and shielding grounding system,DC grounding system,lightning protection grounding system and so on.
