[0002] During the cable power transmission, in order to ensure the normal operation of the power grid, maintenance personnel need to regularly detect the cable current in each area to evaluate the operation status of the cable. In traditional evaluation operations, for low-altitude cables, the detection is often achieved by staff climbing poles or power supports and cooperating with clamp meters. However, for high-altitude cables, due to the high installation height, there is no good solution. Relying solely on manual climbing has a high labor intensity, high operation difficulty, and certain operation risks, such as electric shock and falling, threatening the life and health of maintenance personnel. At the same time, the traditional detection mode has a relatively low detection efficiency and cannot meet the actual detection needs. Content of the Utility Model
