接地阻抗测试是检查接地装置是否良好的重要试验项目。接地阻抗测试时,需要在变电站外长距离放置电压线和电流线各一根,长度为变电站对角线长度的3-4倍,500kV变电站接地阻抗测试时单根大约需要2000米,为满足测试准确性又需要通过较大电流,这就需较粗的铜测试线,按2000米线盘为例,重量在6公斤以上。单纯依靠人力抬着线盘移动进行收放线极为费力。而且,收线时如果不对测试线的位置和方向进行控制,会造成测试线大量集中缠绕在绕线辊某处,既不整齐也不紧实,放线时容易打结。传统收线方法为人力控制方向,收线效率低。 Grounding impedance test is an important test item to check whether the grounding device is in good condition. When testing the grounding impedance, it is necessary to place a voltage line and a current line at a long distance outside the substation. Sexuality needs to pass a large current, which requires a thicker copper test line. Taking a 2000-meter wire reel as an example, the weight is more than 6 kg. It is extremely laborious to rely solely on manpower to carry the wire reel and move the wire reel. Moreover, if the position and direction of the test line are not controlled when the line is taken up, a large number of test lines will be concentrated on a certain place of the winding roller, which is neither neat nor tight, and is easy to knot when unwinding. The traditional take-up method is to control the direction manually, and the take-up efficiency is low.
