摘要
杆塔接地电阻测量是掌握线路防雷水平的重要手段,是为线路大修技改提供依据的基础工作。当前,杆塔接地电阻测量靠人工展放导线,造成测量效率低、接地导线使用寿命短、浪费严重,运行工区结合QC活动研制出了便携式接地放线器,将电压、电流线集于同一装置内,具备同时收、放线的功能,不仅大大提高了测量效率,而且接地导线不再出现打结现象,用放线器进行了700次以上的测量,接地导线未出现任何损伤现象,有效的降低了运行成本。
The measurement of the pole and tower grounding resistance is the important method to grasp the lightning protection level of the line and is the foundation work to provide basis for line overhaul or technical reformation.At the present time,in the tower grounding resistance measurement,the conduct wire was manual placed,which reduces the measurement efficiency,shorten the service life of the wire and causes waste.Combining with the quality control(QC) activity,the portable wire placer was developed by the ...
