For example, chinese patent with publication number CN113219281B discloses a device and method for inspecting the cause of line loss abnormality, in which a driving motor drives a first rotating wheel to rotate, and the first rotating wheel drives a mounting seat to move on a high-voltage cable, and at the same time, the mounting seat drives a second rotating wheel and a third rotating wheel to roll on the high-voltage cable, so that when a section with leakage via the high-voltage cable is used, current is transmitted to an electric energy measuring instrument in a detecting device to detect the section, and when a large amount of current or voltage exceeds standard, a signal sensor can be used to notify a detecting person of the damage of the high-voltage cable. The device has more defects when in use: the existing high-voltage line generally comprises 3 cables (such as live wires) at intervals, when all overhead cables are detected, the device needs to travel to the head along one cable and then return, and then a worker manually installs the device on the other cable to detect the next cable, so that the whole detection needs to waste a long time; in addition, because the battery power supply amount carried by the inspection device at high altitude is limited, precious electric energy can be wasted due to no-load reset, and the endurance time during detection of the inspection device is greatly adversely affected; in addition, the manual line changing operation of the staff at high altitude is time-consuming and labor-consuming, and has large danger coefficient, thereby being unfavorable for safe work; meanwhile, the device can only determine the fault point position through the value of the current and the voltage, has limited detection accuracy, and can not accurately judge the specific cause of the fault.
