摘要
接地电阻测试仪是电力行业中一种常用的计量器具。本文通过在日常检测工作中的实践并参考了《军用内燃机电站通用试验方法》、《机电设备接地技术》,论述了接地电阻的定义性质,综合分析了油气勘探不同地质条件下,接地电阻值与大地电阻率的比例关系,归纳总结了降低大地电阻率的实际方法,详述了接地电阻测试仪在生产现场的主要测量方法。
The grounding resistance tester is a common measuring instrument in the electric power industry.This paper discusses the definition and nature of the grounding resistance through the practice in the daily testing work and reference to the general test method of military internal combustion engine power station and the grounding technology of mechanical and electrical equipment,In this paper,the ratio between the value of earth resistance and the earth resistivity under different geological conditions of seismic exploration is analyzed comprehensively,the practical methods of reducing the earth resistivity are summarized,and the main measurement methods of the earth resistance tester in the operation site are described in detail.
