摘要
防雷减灾一直是气象灾害防御工作的重点,对接地电阻测量可以有效地检验防雷装置在基础接地方面是否合格,也是整体防雷装置检测中不可或缺的重要部分。在防雷装置检测工作中,由于被测量物采用的接地方式不同、接地装置客观环境的不同,经常遇到接地电阻测量读数不稳定、不准确的现象,从而导致数据缺乏公正性。对此,笔者通过多年的实践对不同检测场所的防雷装置检测进行了归纳总结,以供探讨。
Lightning protection is one of the means for detecting an important part of the mine disaster reduction, and one of the earth resistance measurement is the key and the main content of the lightning protection device testing, also important technical indicators, but also the determination is the entire mine facilities qualified important basis. In routine testing work,due to the different grounding object to be measured using different grounding objective environment, often encountered ground resistance readings unstable and inaccurate phenomenon, if not carefully analyze local conditions, proper calibration,measurement the result will affect the accuracy of measurement affect the impartiality of the data. On this, The writer of this paper conclued testing methods of lightning protection devices through the practice and exploration of several years.
