技术领域technical field

背景技术Background technique
近年来，随着电网规模的迅速增长，变电站及线路数量急剧增加，由于设备长时间运行，一些关系生命安全的变电、线路、台区设备的接地体或接地网一旦发生腐蚀脱离，将会引发重大的安全事故。在这种情况下，一方面要求运维部门加强设备巡视及维护，另一方面需要通过采用简易接地检修装置来提高设备检修效率，从而提高设备运行的的安全稳定性。In recent years, with the rapid growth of the grid scale, the number of substations and lines has increased sharply. Due to the long-term operation of equipment, once the grounding body or grounding grid of some life-related substations, lines, and station area equipment corrodes and detaches, it will lead to major safety accidents.
