石墨基接地材料的研究

Study on Graphite-Based Grounding Materials

探讨了现有传统金属接地网面临的运行维护问题,提出了接地装置新材料石墨基。系统阐述了使用传统金属接地材料降阻的困难,如开挖受限,使用传统金属接地体数量多,难以开挖的问题,同时指出石墨基接地装置具有抗腐蚀、易施工、运输方便、环保等特点,可有效解决土壤电阻率过高问题,是取代传统接地材料的一种趋势。

The operation and maintenance problems of the existing traditional metal grounding grid are discussed,and a novel material using graphite base as grounding device is proposed.The difficulties of using traditional metal grounding materials to reduce resistance,such as limited excavation,a large number of traditional metal grounding bodies,and difficulties in excavation are introduced systematically.At the same time,it is pointed out that the graphite-based grounding device has the characteristics of corrosion resistance,easy construction,convenient transportation,and environmental protection,which can effectively solve the problem of excessive soil resistivity and is a trend to replace traditional grounding materials.
