摘要
接地装置在输变电工程中是个特殊的项目,其工程质量不仅关系到电网中重大设备的运行安全,也关系到电气运行人员的人身安全。在大接地电流系统中,接地装置直接影响继电保护动作的正确性;在小接地电流系统中,不合格的接地网将对巡视设备的人身安全构成严重威胁。下面就针对这个问题进行探讨。
Grounding device is a special project in transmission and transformation project, the project quality is not only matters the power grid in the safe operation of major equipment, but also relates to the electrical safety of operating personnel. In the large ground current systems, grounding protective actions directly affect the accuracy; in small current grounding system, unqualified grounding grids will pose a serious threat to safety of personnel, the problems are discussed according to this.
