摘要
合理地设计和安装接地装置对无线电实验室、电磁兼容实验室以及电磁屏蔽室等具有十分重要的意义。分析了影响接地线电阻和流散电阻的主要因素 ,提出了结合电磁兼容实验室的特殊要求进行接地线、接地体选取的方案以及通过土壤改良来降低土壤电阻率的具体措施 ,并简要阐述了接地装置安装施工的过程及接地电阻测量的方法。
It is important to design and fix the earthing set rightly for radio laboratory, EMC laboratory or electromagnetic shielded enclosure. After analyzing the main factors for earthing wire resistance and diffusion resistance, this paper presents the project for selecting earthing wire and earthing body , and the detailed methods for reducing soil resistivity according to the special needs of EMC laboratory. At last, this paper narrates the process of fixing the earthing set and the measurement of earthing resistance.
