According to the requirements of grounding tools, operation types, maintenance planning of the entire power grid, and specific implementation of operation standards, the existing main grounding wire safety protection methods are usually based on dispatching plans and unified power outage arrangements, and the number of grounding wire groups listed by the operating unit according to the work ticket Compared with the pole tower, after the power failure of the whole line, a work order is issued; the staff handles the work ticket and explains the safety measures and dangerous points; On the side, multiple working groups need to take good grounding protection measures. When working at high altitude on poles, the higher the voltage level, the greater the distance between the grounding point and the wire, the larger the angle of rotation of the line pole tower, the longer the grounding wire is required, and the less easy it is for personnel to hang up when working; sometimes when there is wind, The hang time required for the job is just longer. During the operation process, the labor intensity of the personnel on and off the pole is high, which may easily cause muscle fatigue and cause danger. Especially the operators of pole towers are very prone to high-altitude fall accidents. Due to the long suspension time of the grounding wire, the working section is not protected, and other working groups cannot start working, which will affect the work progress and delay the work time. Therefore, the existing technologies are all implemented manually, which can be implemented when the voltage level is low, but it is very difficult to implement on ultra-high voltage and ultra-high voltage lines.
