钢结构预制装配式变电站接地系统研究

Study on Grounding System of Steel Structure Fabricated Substation

预制装配式变电站通过工厂预制和现场安装两个阶段建设,因其建设周期较传统变电站得到明显缩短,更加适应了电网建设步伐,逐渐成为城市变电站推崇的建设方式。接地网作为变电站设备接地及防雷保护接地系统,对安全运行起着重要的作用。钢结构预制式变电站对于变电站的接地系统设计提供了新的理念,为优化设计方案、节约接地材料提供了条件。本文以上海兴邦110 kV变电站为例,研究钢结构预制装配式变电站的接地系统,阐述该方案的优势。

Through the two stages of construction of factory prefabrication and site installation, fabricated substation is becoming more and more respected city substation construction side because it can accelerate construction schedule of power grid. Grounding System is important for safe operation, because it is the lightning protection of the substation and the ground connection of electrical equipments. Steel structure Fabricated Substation has offered new idea for optimizing design and saving material. Taking Shanghai Xingbang 110 kV substation as an example, this paper has completed the research of grounding system of steel structure fabricated substation and elaborated the advantage of this system.
