架空输电线路接地电阻测量研究

Overhead Transmission Line Grounding Resistance Measurement Study

传统的架空输电线路接地电阻在实际的测量工作中,由于存在比较大的离散性和不准确性,因此直接影响着线路的防雷水平和雷击跳闸率的高低.针对上述问题,介绍架空输电线路接地电阻的测量方法以及测量误差产生的原因,从多个方面对接地电阻的测量技术进行分析研究,并针对减小测量误差、提高测量效率提出了相关改进措施.

Traditional overhead transmission lines in the actual ground resistance measurements, due to the presence of relatively large discrete and inaccuracy, and therefore directly affects the level of the horizontal lines and lightning trip rate. In response to these problems, describes methods of measurement of earth resistance overhead transmission lines and causes of error in the measurement, analysis and study many aspects of earth resistance measurement techniques, and for reducing errors, put forward relevant improvement measures to improve measurement efficiency.
