摘　　要：实验室接地主要在实验室基础建设和装修改造过程中实施,是高校实验室管理中极易忽视的重要环节。为做好实验室接地精细化管理,文章从接地的重要性出发,讨论了实验室接地种类和独立接地对提升精密仪器信噪比的作用,并分析了接地不当或缺失的风险。文章提出了满足仪器设备使用需求的降低接地电阻解决方案,在实验室运行管理中可通过检查表对实验室接地情况进行检查,确保接地系统持续有效。[Objective]Laboratory grounding indicates strong professionalism and is mainly implemented in laboratory infrastructure construction and renovation processes,which are quite easy to neglect.The core objectives of the research were to delve into the significance and complexities of proper grounding in university laboratory settings,which included examining the roles of grounding in enhancing safety,protecting equipment,and maintaining the accuracy of the experimental results.This study raised awareness of the often overlooked but critical aspects of grounding in laboratories.[Methods]To achieve the aforementioned objectives,this paper first discussed the various types of grounding required in a laboratory setting and then reviewed the essential functions,such as protection against electric shocks,prevention of electromagnetic interference,stabilization of equipment operation,and dissipation of static electricity.The protective function of grounding,i.e.,to prevent electric shocks and damage to equipment by diverting currents to the earth,was highlighted.The importance of grounding in shielding sensitive electronic devices from electromagnetic interference and its vital improvement of the signal-to-noise ratio of precision instruments,which could compromise the quality and reliability of data obtained from experiments,was also underscored.Risk analysis was conducted to illustrate the potential consequences of improper grounding,including power instability,increased likelihood of electrocution,fire and explosion hazards,damage to instruments,and data distortion.This study proposed the implementation of a comprehensive grounding design strategy for the Analysis&Testing Center at North China Electric Power University,which might mitigate these risks.This comprehensive grounding design strategy involved the use of local equipotential bonding boxes,complex grounding networks,and specific engineering techniques to reduce ground resistance to meet the stringent requirements of high-precision instruments.[Results]Implement
