摘要
通过调研相关接地电阻测试方法,提出了利用室内接地接线柱和供电电源地线连接组成导电测量环路,基于该测量环路采用钳形接地电阻测试仪的接地电阻测试法。实践证明该测试方法简便可行,解决了在复杂地理环境中进行接地电阻测试的一个难题,同时基于该测试方法提出了接地电阻持续监控的保障方案。该测量方法可推广应用于所有计量校准测试实验室和机房的接地电阻测试,具有较大的应用价值。
The definition, role and classification of the ground resistance are described in this paper. And two kinds of ground resistance test methods： three-wire ground resistance test method and pincer-like ground resistance test method are weightily introduced. Through research and combined with the actual situation of the calibration ＆ test Laboratory, a ground resistance test method using pincer ground resistance tester is introduced, which is based on the conductive measurements loop formed by the indoor grounding terminal and power supply ground wire. The method proves a simple and feasible way to solve the test difficulties in complex geographic environments. And based on the method a continuous monitoring program of ground resistance is also proposed. The test method can be applied to all calibration ＆ test laboratories with great application value.
