电力工程接地材料研究现状及展望

Research status and prospect of grounding material in power engineering

常规接地材料在一些土壤环境中腐蚀速率较快,给接地造成安全隐患,并且在高土壤电阻率地区仅使用金属接地体难以达到接地电阻值要求,采用耐蚀接地材料和降阻接地材料能较好地解决上述问题。针对这2类材料的研究进展及应用状况进行了综述,并展望了接地材料今后的发展方向。

The corrosion rate of conventional grounding material is fast in some soil environment,resulting a security risk for grounding.In addition,the earthing resistance is hard to meet the requirement in high soil resistivity area,adopting anti-corrosive grounding materials and resistance reducing materials can solve above problems effectively.The present research situation and application status of these two kinds of materials were reviewed,the research and development prospects of grounding materials was also put forward.
