摘要
降低输电线路杆塔接地电阻,是保证电网安全、稳定运行的重要措施之一。以降低苏丹BABANUSA-ADILA 220 kV输电线路铁塔接地电阻为例,对影响接地装置电阻9类要因进行分析、研究,探索了有效降低接地射线电阻值的方法,应用效果良好。
Reduction of the grounding resistance of transmission line tower is an important measure to ensure the safe and stable operation of power grid.Taking the BABANUSA-ADILA 220 kV transmission line tower as an example,key factors that affect the resistance of the grounding devices are analyzed.Effective measures are then proposed to reduce the resistance of the grounding wires.Satisfactory application performance is achieved.
