摘要
在某工程中塔位移动后,实测接地装置的接地电阻值大于规程要求值,对此进行分析,采用三维复合接地装置降低接地电阻,解决工程中因接地装置敷设场地小而使工频接地电阻不能满足规程要求的问题。
After tower position moving, the measured grounding resistance value is normally greater than the rule＇s value. By using three dimensional composition grounding device, grounding resistance can be reduced, it can meet the rule＇s requirement for grounding resistance, due to the grounding device laying field is small in project.
