摘要
通过对接地装置导通的人工模拟试验,得出用直流大电流法和交流小电流法测试较为灵敏,并对多个变电所的接地网进行了实测和分析,建立了变电所接地网导通试验的计算机管理系统,为设备接地网的脱焊、腐蚀等缺陷的处理提供技术支持。
According to the artificial simulated tests of ground connection, it gives out that methods to use large current of DC and small current of AC to test is more sensitive. It goes on the actual tests and analysis and sets up the computer management system of ground grid in substations.It provides the technical supports on handling defects of sealing off and corrosion in ground grid.
