新型非金属材料在接地网中应用研究进展

Application Research Progress of New Nonmetallic Materials in Grounding Grid

输变电系统接地网现有接地材料的腐蚀严重威胁电力系统的安全经济运行,开发新型耐腐蚀接地材料势在必行。通过查阅国内外相关文献、资料对目前的接地材料进行汇总、分析,归纳总结了现有接地材料应用到接地网中存在的问题;对比分析了新型非金属材料与现有接地材料在耐腐蚀性、极限耐受温度、经济性等方面存在的差异,研究了新型非金属材料应用在接地网中逐渐替代现有接地材料的可行性与经济性。

The corrosion behavior of transmission system grounding grid existing grounding material a serious threat to the safe operation of the power system, the development of new type corrosion-resistant materials is imperative to the ground. After a review of relevant literature and information domestic and foreign, on the current grounding material aggregated, analyzed, summarized the existing problems that existing grounding material applied to grounding grid; comparative analysis existing differences of the new type non-metallic material and the existing grounding material in corrosion resistance, extreme temperature tolerance, economy, etc. Study on new type non-metallic materials in the grounding grid gradually replaces the existing grounding material feasibility and economy.
