摘要
110kV变电站接地网,由于年久老化,存在接地电阻值高的缺陷,根据设备的分布及现场地形情况,设计采用安装深埋接地极的方法施工,取得了良好的效果,为一些年久老化接地电阻值偏高需要改造的老接地网积累了经验。
There are shortcomings of high earthing resistance values due to a geing in the earthing network of the 110 kV substation. Based on distribution of the devices and site topography, the method of installation of the earthing pol e deeply buried is used in construction, which has obtained better effect and pr ovides experience for the old earthing networks that have high earthing resistan ce values and that need transformation due to ageing.
