摘　　要：针对处于沿海盐碱地质等地区的输电线路接地电阻易受腐蚀的问题,提出采用一种新型镀铜接地装置作为输电线路接地电阻的新方法,并应用于生产实际中。通过分析新材料在接地系统中应用的各项效益指标,并与之前传统的接地电阻进行对比,可知利用镀铜作为接地电阻材料,能有效地减少由于雷击而接地电阻不满足要求造成输电线路跳闸的故障,为电力系统的安全稳定运行提供可靠保障。Aiming at the problem of easy corrosion of grounding resistances in electronic transmission lines in coastal saline regions,this paper proposes a new copper-plated grounding resistance which is practiced in production.Through analyzing the performance of the new material used in the grounding system,and comparing it with existing grounding resistance,it is concluded that the copper-plated resistance can effectively reduce transmission line tripping which is caused by lightning for the grounding resistance that doesn＇t meet the requirements,on the same time,reliable guarantee for power system is offered.
