摘要

为满足复杂土壤环境对接地材料耐腐蚀性以及高频雷电流和短路故障入地电流对接地材料热稳定性的要求

研制了一种强通流能力的石墨基柔性接地材料。通过耐腐蚀试验分析了石墨基柔性接地材料与钢材类材料的耐腐蚀性能;试验对比了圆钢与石墨基柔性接地材料与不同土壤的接触性能;仿真研究了石墨基柔性接地材料的热稳定性以及冲击散流有效利用长度。研究结果表明:石墨基柔性接地材料耐腐蚀性强

预期使用寿命超过30 a;其与土壤接触性能优于圆钢

接触电阻降低约30%;冲击散流有效长度增加约30%。

Abstract

In order to meet the requirements of corrosion resistance of grounding material and thermal stability of the grounding material under the condition of power frequency current and high frequency lightning current scattering into the ground in the case of short circuit fault and lightning strikes

we developed a kind of high current capability graphite flexible grounding material. The corrosion resistance of the graphite flexible grounding material and the steel type grounding material was compared by the simulated corrosion tests. The contact performance with different soil of graphite flexible grounding material and round steel was compared. The thermal stability and the impulse current effective length of this grounding material were studied by means of simulation calculation. The results show that the graphite flexible grounding material has a strong corrosion resistance

whose reliable service life can exceed 30 years. Compared with the round steel

the contact resistance with soil can be reduced by about 30%

and the impulse current effective length can be increased by about 30%.
