摘要
着重阐述了大型精密仪器设备接地保护的重要性及有关接地的概念、接地类型、接地电阻的计算公式。以大型精密仪器设备D8-X射线衍射仪接地装置的设计与安装为例，介绍了接地电阻值的理论计算、接地体的设计、敷设与安装、接地电阻值的测量及接地装置的检查与维护方法。
This essay will elaborate the significance of the large- scale precisely instrumental equipment grounding protection and the concepts related to, the grounding types, and calculating formulas of the grounding resistance. Moreover, the essay takes the design and installment of the large- scale precisely instrumental equipment D8 Advance X- ray diffraction meter grounded instrument as an example, in order to introduce the calculating methods of the grounding resistance, embedding and installing methods of grounded instrument, the measurement of grounded resistance and the operating and maintenance of grounded equipment.
