摘要
地铁接地电阻的检测工作是地铁各设备防雷及电气安全性能检测的一个重点和难点,其准确性是确保检测数据公正科学的前提,但实际检测中受到检测环境和对象的限制,不能按规定要求布置接地棒或使用标准长度测量导线的情况经常发生,文中介绍地铁接地的含义并结合其特殊性论述接地电阻检测的一些体会。
Ground resistance testing is an important and difficult work in safe testing of thunder defending,the veracity is the guarantee of justness and scientific of testing result.In practicality testing working,due to the testing condition and the restrict of testing object,it＇s hard to dispose the sticks according to the rule,and it almost impossible to use standard testing lead.The paper discuss the meaning and particularity of earth resistance testing of subway,and some advice about how to test credibility.
