摘 要:介绍离子棒接地系统的构成与工作原理,与传统接地系统比较,具有不易受外界环境和气象条件干扰,寿命长、节约材料、有利环保等特点。在青海高海拔土壤电阻率较高的地区,部分铁塔接地电阻值接近临界或无法满足设计工频电阻值,采用离子棒接地系统后,接地电阻值满足规范要求。This paper gives a detailed introduction to the constitution and operating principle of the ion alley bar grounding system. Compared with traditional grounding system, the ion allay bar grounding system is free of environment and weather conditions, is of long life, made of less material and friend to environment. In some high altitude regions with high soil resistivity, the grounded resistance of power transmission line towers is close to the limit or unable to be accordance with the designed power frequency resistance value. By application of the new grounding system the grounding resistance of the tower is accordance with the design value.
