| 摘 要： | 为保证系统短路电流快速散失,保证人身和电气设备的安全运行,变电站接地网有着重要的作用。随着电网容量的急剧增加,系统短路故障电流越来越大,同时变电站布置日益紧凑、占地面积较小,按照常规接地网设计,接地电阻值将难于满足规程要求。本文结合渭南110千伏开发区变电站接地网实例,介绍了三维立体接地网设计的基本原理,能够保证接地系统的可靠、长效。

| Abstract: | In order to ensure that the system short-circuit current rapid loss, physical and electrical equipment to ensure safe operation of the substation grounding grid plays an important role. With the dramatic increase in grid capacity, the system short-circuit fault current increases, while the substation layout increasingly compact, small footprint, according to the conventional design of grounding, grounding resistance value will be difficult to meet code requirements. In this paper, Weinan Zone 110 kV substation grounding grid example, introduced the three-dimensional design of the basic principles of grounding, grounding system to ensure reliable, long-lasting. |
